Although the printer is fun to watch, kids tend to get board with it in just a few minutes. I like to come up with classroom projects that let the kids use things that are printed with the printer. Since it is so cheep it is also fun to print something ahead of time that they can take home.<br />
<br />
For the kindergarten class we printed some flowers that the kids could use to put together a cut spring time flower pots just in time for mother's day:<br />

So my Ultimaker2 extruding head got clogged, really bad. Something got jammed while printing and I could not get the filament to feed. This had happened once in the past when I tried using some really cheap filament but I am not sure the real root of the problem this time. In any case, I found using the "atomic" method for getting a clean nozzle. This method is named after MostlyAtomicBob who described the method for the first time in the following post:</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">

<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
Here is a summary of the steps that I used:</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
1) Remove the boden tube from the printer head</div>
<div class="separator" style="clear: both; text-align: left;">
2) Heat up the head to full temperature (around 210 degrees) </div>
<div class="separator" style="clear: both; text-align: left;">
3) Push in a piece of spare filament until I can no longer push or it starts coming out the end.</div>
<div class="separator" style="clear: both; text-align: left;">
4) Reduce temperature to around 90 degrees. Filament should solidify but stay a little soft.</div>
<div class="separator" style="clear: both; text-align: left;">
5) Pull the filament out of the print head.</div>
<div class="separator" style="clear: both; text-align: left;">
6) Repeat steps 2-5 until I get completely clean filament</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
You can see the result of my cleaning in the picture below. The pieces are a little backward and ordered from right to left. Note the really dark char slowly going away and the pieces getting longer as they nest better and better in the print head. </div>

I installed a motion sensor in my basement because the light switch is in an inconvenient place and most of the time we go in this part of the basement my hands seem to be full. The motion sensor fixes this problem and even found a outlet plate on thingiverse that fit perfectly.</div>

The only problem is that the installed switch box is too small for the new sensor and my printed play sticks out a good 15 mm from the box.</div>

My wife and I volunteered to lead a couple of their meetings with a maker theme. I thought the 3D printer is always a hit and what better project for girl scouts than cookies (yes I realize this is cliche but it is still fun). I did some searching on the internet and came up with a variety of ways the girl scouts could design cookie cutters. However, I had a checklist of desires and none of them quite made the "cut" (I will stop now). Here is what I was looking for:<br />

<li>An option to upload and trace a picture. This is necessary because I do not have enough computers for the group. I saw a similar activity at the Detroit Maker Faire and I thought hand drawn images would be more natural.</li>
<li>Ability to add both internal and external features on the cookies. What I would really like is two layers so the cutters could imprint on the cookie as well as cut through the cookie. </li>
<li>Ideally an online app so I do not have to download anything. </li>
<li>Obviously an easy way to output stl files I could use with my printer.</li>
</ol>
<br />
<b>CookieCaster: </b><a href="http://www.cookiecaster.com/#editor">http://www.cookiecaster.com/#editor</a><br />
Online app for drawing outline of cookie cutters. This makes for a fun group project because you can scan and upload hand drawings into the editor and trace them. The downside is that this editor only does a cookie outline and not the insides. Here is an example we did:<br />

<br />
<b>Cookie Cutter Editor:</b> <a href="http://www.local-guru.net/blog/pages/cookiecutter-editor">http://www.local-guru.net/blog/pages/cookiecutter-editor</a><br />
Downloadable cookie cutter editor. Uses a programming language called processing (written in java). I could not get the MacOS stand alone version to work so I tried to download processing and run the source directly. Still was missing some libraries so I gave up on it. Looking at the examples I do not think it would work much better than CookieCaster and could not get any of the internal details I wanted anyway.<br />
<br />
<b>Thingiverse: </b><a href="http://www.thingiverse.com/apps/customizer/run?thing_id=116042&code=2633da7762519236fd52412f6c8bf143">http://www.thingiverse.com/apps/customizer/run?thing_id=116042&code=2633da7762519236fd52412f6c8bf143</a><br />
<br />
Thingiverse has one of their customizable apps. This one was really nice because it could do some internal details. Seems to only have one height but having details is better than the other two. However, this app also only had an option for online editing and no way to upload a picture. It was also a difficult interface to master. For example, it does not handle overlapping editing very well and was particularly hard to get right with my laptop's touchpad. Here is an examples we made:<br />

<br />
Although none of the apps seem like they would work, none of them really fit all of my criteria. I am going to have the girl scouts use Cookie Caster since it is the one that works with pictures. Please stay tuned for future blog posts with details highlights from the girl scout projects.<br />

I like handing them to people with the light coming from the front. Most of the time they are polite and say, "that's nice." Then I have them hold the lithophane to let the light come in from the back and the image pops out. "Wow," "cool" they say and the expressions on their faces are ones of awe and surprise. <br />
<div>
<br /></div>
<div>
For christmas this year, my wife came up with the idea of putting a picture of the kids inside of a lithophane inside of a 3D printed snowflake.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjF5Gp4dTpR-LNDQpcYEBZSzsSdGnyLYfbF_CLEpgmdK4V64caNmldBcmfHpP3kaDoRB0A8aD8h78Kq5sUPLUefiw2_cE-P860B5zBtHTsHAXoWjlJtgSSQxmPvF6phwsnxS5KRRppoB28/s1600/il_570xN.688476899_eapl.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjF5Gp4dTpR-LNDQpcYEBZSzsSdGnyLYfbF_CLEpgmdK4V64caNmldBcmfHpP3kaDoRB0A8aD8h78Kq5sUPLUefiw2_cE-P860B5zBtHTsHAXoWjlJtgSSQxmPvF6phwsnxS5KRRppoB28/s1600/il_570xN.688476899_eapl.jpg" height="320" width="180" /></a></div>
<br />
Took a while to figure out but got much easier when I found an openscad program to generate snowflakes I found on Thingiverse:<br />
<br />
<a href="http://www.thingiverse.com/thing:74322">http://www.thingiverse.com/thing:74322</a><br />
<br />
I picked a random seed that fit well with my idea and then I tried importing my the stl file from my lithophane program. I could not quite git it to work. So, instead I decided to make the print in two parts and glue them together. I did some minor modifications to the openscad file add an area for the lithophane, the hole for a ribbon and in latter modifications a way to add the year: <br />

<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
You can download the stl file for the frame on youmagine:</div>

<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
Now I just print the lithophane separate from the frame and it turns out quite well. <span style="text-align: center;">Here is a video:</span></div>

It was over 10 years ago, it was fairly expensive to operate and it printed in a kind of expensive wax. <br />
<br />
Anyway, this was the first time I saw a lithophane. It was a picture of Marilyn Monroe that just popped out if you held it so up to a light so that it is backlit. It was just so cool that I really wanted to make some Lithophanes when I got my 3D printer. <br />
<br />
Once I finally found some time I did some research and there were a few programs on the web which would make lithophanes for me. <br />

I tried a few but nothing excited me so I just wrote one myself. I am very pleased with the results:<br />

If you already have a printer I am happy to send you the MATLAB code to generate these for yourself. However, I must warn you that it is not very robust and I am reluctant to post it until I can add a bunch of error checking and a little better user interface. It's also written in MATLAB, ideally I would like to change to something like Python but I am just quicker working with MATLAB.Anonymoushttp://www.blogger.com/profile/05133503093028104989noreply@blogger.com0tag:blogger.com,1999:blog-714277384851084514.post-54121070368385240902014-11-28T13:37:00.000-05:002014-11-28T13:37:03.479-05:00Learning to use a sewing and embroidering machine<div class="separator" style="clear: both;">
We are trying to turn our basement into a mini makerspace for the kids. Quite a few years ago my wife bought a fancy sewing machine that does embroidery which I thought would make a fun addition. My eldest daughter and I got playing with the machine and it is quite amazing. In no time at all we were able to embroider a bow and make a cute little pillow. I look forward to seeing what we will make next time.</div>

Over the summer we spent some time up at our Aunt and Uncle's cottage. Kids were picking up a lot of nature detritus to "keep" and my wife got the idea to make a Fairy House. Turned out to be a really fun project. I particularly like the paper lantern made from an old hornet's nest and the ladder. The trick seems to be start with the big stuff and keep filling in the details until it looked right. </div>

<span style="font-family: 'Helvetica Neue Light', HelveticaNeue-Light, helvetica, arial, sans-serif;">We are spending time with the kids at our aunt and uncle's cabin in northern Michigan. This is an old hunting cabin but it is not exactly roughing it. There is air conditioning and internet. </span></div>
<div>

I am worried that the kids are spending too much time inside on the devices. At some point yestuday I banned the devices and told my eldest to go out and build a fort:</div>

I decided that this would be a great project for me to do with my kids. Step one was to find the parts. <br />
<div class="separator" style="clear: both;">
</div>
<ol>
<li>Cell phone motors (pack of 50). </li>
<li>Batteries. Large pack ordered on amazon: <a href="http://amzn.com/B0043SAFK0" style="font-family: Arial, sans-serif; font-size: 12.727272033691406px; line-height: 19px;">http://amzn.com/B0043SAFK0</a></li>
<li>Glue</li>
<li>Double sided tape</li>
<li>Toothbrushes</li>
</ol>
<div>
Between the motors and batteries, the price per brushbot was getting expensive. So Instead of buying a bunch of toothbrushes I decided to see if I could print the body instead. I came across the following design on thingiverse that did exactly what I wanted:</div>
<div>
<br /></div>
<div>
<a href="http://www.thingiverse.com/thing:68968">http://www.thingiverse.com/thing:68968</a></div>
<div>
<br /></div>
<div>
I ended up using only the "legs" and the body. I also think it was also better to assemble the body upside down. In any case, I was able to print out these three parts and just let the kids assemble them using superglue:</div>
<div class="separator" style="clear: both; text-align: center;">

<div class="separator" style="clear: both; text-align: left;">
<span style="text-align: left;">Then we had to strip the wires for the motor (probably the trickiest part) and remove the sticker cover on the motor to stick it to the "bug". </span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEit5DUJxJEX5AI4k_pUsG9dbGatiquYWcycLWGBNtSI7paPcTZ9wnWFu6qJ81L-1FkLYgFw6gh4N13x8x7GTD4OZlRVz1z4tF0gcY5l_ZtEBxfg6CHKNjH2zwS8ZFd840tP83FMdi7kO_o/s1600/blogger-image-1701867005.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEit5DUJxJEX5AI4k_pUsG9dbGatiquYWcycLWGBNtSI7paPcTZ9wnWFu6qJ81L-1FkLYgFw6gh4N13x8x7GTD4OZlRVz1z4tF0gcY5l_ZtEBxfg6CHKNjH2zwS8ZFd840tP83FMdi7kO_o/s320/blogger-image-1701867005.jpg" width="320" /></a></div>
<div class="separator" style="clear: both; text-align: left;">
Add small pieces of double sided tape and lay down one of the wires on the tape. Then have the kids stick the battery on top of the tape and use a second piece of tape to secure the top wire. </div>
<div class="separator" style="clear: both; text-align: center;">

<div class="separator" style="clear: both; text-align: center;">
At this point the bug bots should start dancing. We used an upside down paper plate as a "sumo" rink to see which bug bot could stay on the longest. </div>

Overall this activity was easily complete in 15 minutes and the kids had something to take home with them. Special thanks to <a href="http://www.thingiverse.com/ekaggrat/overview">ekaggrat</a> at thingiverse for posting his 3D designs which made this project possible.<br />

I decided that this would be a fun project for my 3D printer. There are a lot of drawer guides in thingiverse. I downloaded a few drawer guild stl files but none of them really fit my dawers:</div>

After the flat part was printed I put it in a warm pan on the stove to soften the plastic a little so I could put an appropriate bend in it. Here is a link to my files if you are interested in working with them:</div>

<div class="separator" style="clear: both; text-align: center;">

<span style="font-family: Arial; font-size: 13px;">To start we took two pictures, one with everyone in an away team formation and one with just the background</span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEglHjOLRkDAIq2-csK5duE4WiTG7qq9VU0gXj1O347CA5YcDSEpV7QH7aqPzQGxFFhy7urcjeN8bVudkcG7tkTXzUWu9m-bPR3lxKhJgbjXQRUYK-As7stCm3sklkaynW2ugKXB3j1mZjo/s1600/small_DSC_0859.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em; text-align: center;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEglHjOLRkDAIq2-csK5duE4WiTG7qq9VU0gXj1O347CA5YcDSEpV7QH7aqPzQGxFFhy7urcjeN8bVudkcG7tkTXzUWu9m-bPR3lxKhJgbjXQRUYK-As7stCm3sklkaynW2ugKXB3j1mZjo/s1600/small_DSC_0859.JPG" height="214" width="320" /></a></div>
<br />
<span style="font-family: Arial; font-size: 13px;">I then wrote a simple program to add the two images together using a weighted sum. This technique looked okay</span><span style="font-family: Arial; font-size: x-small; text-align: center;"> but I also wanted some noise. I used the matlab imnoise function to </span><span style="font-family: Arial; text-align: center;"><span style="font-size: 12.727272033691406px;">create</span></span><span style="font-family: Arial; font-size: x-small; text-align: center;"> some sparkles. Inicially just a few, grow to a lot about halfway and then disparate as the people materialize. </span><br />
<span style="font-family: Arial; font-size: 13px;"></span><br />
<span style="font-family: Arial; font-size: 13px;">The trick is to get the speckles to only appear where there are people. I could have tried some clever image subtraction trick to find the region that changed but it was just as quick for me to use GIMP to cut the people out and make a simple flag array using the following Matlab code. I had to also use GIMP to paint over any white spots in the image. Fortunately for my image there was very little white. I ended up with the following (I guess I could also have just select the white and set everything else to black).</span><br />

<br />
<br />
<span style="font-family: Arial; font-size: 13px;">Now, potting All the components together and looping from 0 to 100 I was able to create a directory of images that I wanted and stitched the images together using ffmpeg.</span><br />
<span style="font-family: Arial; font-size: 13px;"><br /></span>
<span style="font-family: Arial; font-size: 13px;">To top it off, I found a transporter like sound on the net and used my copy of Camtacia (</span><span style="font-family: Arial;"><span style="font-size: 12.727272033691406px;"><a href="http://www.techsmith.com/camtasia.html">http://www.techsmith.com/camtasia.html</a>) </span></span><span style="font-family: Arial; font-size: 13px;"> to put the audio and video together.</span><span style="font-family: Arial; font-size: 13px;"><br /></span>
<span style="font-family: Arial; font-size: 13px;">Here is my final product:</span><br />

I participate every year with my kids but was extremely enthusiastic that the theme this year was for makers so my goal is to show off the 3D printer and make some things for the 50 or so kid participants. It's no fun watching a 3D printer without having something to touch and even take home. However, I am fairly new to 3D print design so this was only my second endeavor to design something of my own. <br />
<div>
<br /></div>
<div>
I was trying to think of a project where each student would get a gismo to take home but we could put them all together to build something as a group. This fit in with the theme quite nicely however most of my ideas were a little too complex to get off the ground.<br />
<br />
I finally settled on building gears with logos and holes on one end so they could attach them to their backpacks. I thought I could assemble all of the gears together to make one big machine the kids could play with that all worked together. With this plan in mind I searched though thingiverse and youmagin for some designs I could use as a starting point. I was really excited when I found this one by <a href="http://www.thingiverse.com/thing:40410">http://www.thingiverse.com/thing:40410</a> that can be used to make gears that fit into Lego technics. I have a ton of lego technics and I really liked the idea that the motivated students to integrate their gear with their own legos. <br />
<div class="separator" style="clear: both; text-align: center;">

<br />
<br />
After some iteration, I ultimately ended up doing is importing the images into Inkscape and converting them to a dfx file which is a vector map using instructions I found on a couple of website. Here is an example image I loaded into Inkscape<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<div class="separator" style="clear: both; text-align: center;">
<br /></div>
Using this technique I was able to make a variety of gears and they worked well with lego. Here is a video of one of the gears working with my old first generation mindstorm:<br />

<br />
This turned out to be a really flexible design and I was also able to someone elses openscad files to make other gears with different projects I found on thingiverse. For example here is one with a robot in a openscad file from thingiverse <a href="http://www.thingiverse.com/thing:53285">http://www.thingiverse.com/thing:53285</a>:<br />

<br />
I really like this design because it is easy for me to swap out different logos based on the event. I uploaded my source files and these examples to github:<br />
<br />
<a href="https://github.com/colbrydi/gear-givaways">https://github.com/colbrydi/gear-givaways</a><br />

My eldest daughter wanted to make a birdhouse/feeder. It was the middle of winter and I think she was thinking of building it out of wood. However, I realized what she really wanted to do was decorate it using some extra stickers she had. So, we compromised and I cut out a hole in a washed out milkjug. </div>

However it is messy and the logistics of getting the mentos in the coke without getting crazy sticky is challenging. I did a quick search of thingiverse and found a couple of wonderful solutions:<br />

<br /></div>

A short 3D print of the second one and all we needed was Diet Coke, Mentos, string, paperclip and space:<br />

<span style="font-family: Arial; font-size: 13px;">So, I took some measurements and came up with this drawing</span><br />

<span style="font-family: Arial; font-size: 13px;"></span><br />
<span style="font-family: Arial; font-size: 13px;">My goal is to see if I can print this out using a 3D printer. When I started this project I was planning to use the one in the engineering department where I work, but now I have an Ultimaker 2. I know I need an stl file but I was not sure the best way to generate one. After some quick internet searching I found openscad.</span><br />
<span style="font-family: Arial;"><span style="font-size: 12.727272033691406px;"><br /></span></span>

<span style="font-family: Arial; font-size: 13px;"></span><br />
<span style="font-family: Arial;"><br /></span>
<span style="font-family: Arial; font-size: 13px;">I downloaded the software and found the wiki quick start page. It did not take long to figure out the simple language. I started by making a cube and then creating the top. Then I made objects to cut out the inside and the bevels. Here is the resulting model. </span><br />

<span style="font-family: Arial; font-size: 13px;">The hardest part was to get the surface normals for the wedge shape object to face in the right direction. However, once I drew out my points and used the right hand rule things settled in nicely. </span><span style="font-family: Arial; font-size: x-small;">Openscad outputs stl files so all I did was </span><span style="font-family: Arial;"><span style="font-size: 12.727272033691406px;">import</span></span><span style="font-family: Arial; font-size: x-small;"> it into the cura program to generate the gcode for my printer and save it to the SD card to print. The first print was a little too close to my tolerances and I could not get it to fit inside the tripod. However, with some simple modifications to the openscad file I was able to generate a quick release mount that I think looks quite nice and works well:</span><br />

That little monkey is a bit of a maker. I really like the episodes where he tries to build things. In most cases he doesn't get his design right and has to debug and iterate on the design until he has what he wants. It is a very good lesson for our young makers. <br />
<br />
In one episode George decides to make a pinata. My youngest daughter LOVEs this episode and has been asking my wife and I to make a pinata for weeks. A few weeks ago my wife relented and found a really nice youtube tutorial on-line:<br />
<br />

<div class="separator" style="clear: both; text-align: center;">
<br /></div>
We got the supplies suggested by the video and my wife and kids started paper machine a star shaped balloon and party hats. The family ended up making two since the overall costs were about the same. <br />
<br />
We filled them with candy and put one of them to the test this weekend at a family party:<br />
<br />

<br />
The only problem we had was keeping the pinata attached to the string. Ultimately, I had to tie the string around the whole thing to get it to stay. I probably need to follow George's example by iterating and engineering a better process for the second one.<br />

In addition to just having fun and learning how things work, we were able to salvage the stepper motors. I want to try hooking them up to the Arduino (<a href="http://www.arduino.cc/">http://www.arduino.cc/</a>) that my brother gave me for Christmas. If it works, we are going to try and make a reprap (<a href="http://reprap.org/">http://reprap.org/</a>) using parts printed from my Ultimaker 2 (<a href="https://www.ultimaker.com/">https://www.ultimaker.com/</a>).<br />

For years my wife has listened to me think about buying or building a 3D printer. At heart I am a cheapskate and can not justify spending a lot of money on a toy. I even had a <a href="http://www.thingiverse.com/">http://www.thingiverse.com/</a> account and would spend time "liking" things I would print if I only had the printer...<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgQTiC6_J1Fynu6_mnFoL9EQF4XC5NWaANDLLXXpf7Cuk3psRKD6YJTvSHDgjGBKz6M_dnWJ0wkTw93KRtvqv3jGu0kfk7XTZp5oOsN0zmT9qpaVXXkF6j5ihRDjqUlolvDkJ5T7L26aRI/s640/blogger-image-593926156.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"></a></div>

Well, I think my wife got sick of me talking about getting a printer. She not only purchased it for me, but she got what I consider to be one of the top of the line hobby printers: the Ultimaker 2 (<a href="https://www.ultimaker.com/">https://www.ultimaker.com/</a>). I think one of the things that finally convinced her is when she started checking out thingiverse and found stuff she wanted me to print.<br />

I have only had it for about three days, but I can truly say that the Ultimaker 2 is a joy to work with. Although expensive, it came fully assembled and I had it out of the box and making my first print in less than an hour. It has been printing almost non-stop since then. I have made over 24 prints and the thing keeps running: puddle jumper, toy daleks, keychains, hooks, 3d puzzles, all kinds of stuff. Here are a few pictures: </div>

This was my first Maker Faire, and we went as a trial run for the Detroit Maker Faire (<a href="http://www.makerfairedetroit.com/">http://www.makerfairedetroit.com/</a>). It was everything I had hoped: there were plenty of robots, 3d manufacturing devices and other things to touch and play with. My oldest daughter (with help from her papa) even got to do her first soldering using one of the "learn to solder badges" from the maker shed (<a href="http://www.makershed.com/Learn_to_Solder_Skill_Badge_Kit_p/mkls01.htm">http://www.makershed.com/Learn_to_Solder_Skill_Badge_Kit_p/mkls01.htm</a>). I heard a lot about this kit and it was better than I thought it would be:<br />

Specifically </span><span style="font-family: Arial;"><span style="font-size: 12.727272033691406px;">vegetable</span></span><span style="font-family: Arial; font-size: x-small;"> gardens where we can grow, harvest and eat some of our food. I've had a few gardens before, but in our current house it is difficult to have one because our beautiful four legged neighbors (deer) like to snack in our yard. </span><br />
<div>
<span style="font-family: Arial; font-size: x-small;"><br /></span>
<span style="font-family: Arial; font-size: 13px;">I got this idea from a community garden just down the road. They used an old glass door as a small green house. I am using the same idea but as a screened-in space for a little garden. </span><br />
<span style="font-family: Arial; font-size: 13px;"></span><br />
<span style="font-family: Arial; font-size: 13px;">I got the door from our local Habitat resale store and it works great. </span><br />
<span style="font-family: Arial; font-size: 13px;"></span><br />
<span style="font-family: Arial; font-size: x-small;">Here is a </span><span style="font-family: Arial;"><span style="font-size: 12.727272033691406px;">picture</span></span><span style="font-family: Arial; font-size: x-small;"> of the final product. Note, that the door opens for easy top access and the back can be easily removed also by lifting it off the screws I use as hooks.</span><br />

Photography has been a passion of mine since I was my daughter's age. I remember one vacation in Lake Michigan with my family: my Aunt Pat gave me a 110 cartridge camera and basically just let me loose. I was hooked. The only problem with my habit was the cost of developing film, which I tried to pay for in high school by working at a one hour developing store and in college by working on the newspaper and yearbook. Finally, even though the resolution was poor, digital cameras allowed me to feed my habit - and as they continuously get better I haven't looked back.<br />
<br />
I found the plans for this light box on the internet (<a href="http://digital-photography-school.com/how-to-make-a-inexpensive-light-tent">http://digital-photography-school.com/how-to-make-a-inexpensive-light-tent</a>) and thought it would make a good project for me and my kids. A light box will also come in handy if we need to take pictures of the things we are making.<br />
<br />
The first step was to measure and cut the box. This is where we got stuck because the cardboard paper I had was a little old and yellowish. I wanted something cleaner so I had to set this project aside until I could by some better cardboard (and cloth, while I was at it).<br />

I ended up buying Bristol board as recommend in the blog post. It has a nice smooth finish and I think it will work well.<br />

My daughter and I cut out strips of the board and glued them to the box. <br />

Once glued, we added the cloth and tested it out on my android phone. <br />

This looks okay, although I think I need some better (and brighter) lights - but this looks to be a good start.<br />

This is a wonderful place where the university can recycle and reuse some of its vast equipment and supplies. It turns out to be a big junk store. My goal was to find something useful that I could take apart with my kids; I came across this $3 drill that someone had already modified. You can tell by the after market trigger switch.<br />

My daughters and I took this drill apart to see how it works. The girls loved the activity.<br />

We had some trouble getting the chuck off, but overall it was a great way to spend an hour on Saturday. I was just going to throw away the drill, but I think the motor and gearbox may come in handy for a future project.<br />

I like the idea of reverse making. This is an activity well-suited for younger kids. I plan to hit the garage sales this summer looking for things we can take apart and recycle or reuse for parts. Maybe we will build a robot!</div>
