An incredibly fun and engaging toy for kids and adults. Press a button and something lights up. Flip a switch, and everything changes. You'll be amazed at how such incredibly unpredictable behavior can be achieved through cleverly connected switches and pushbuttons.

Build you own kit... The kit can be found on the Jameco website: Fun Light Switch Box

Soldering iron and solder
Drill press (preferred) or hand drill
Drill bits (1/4", 9/32", 13/32", 15/32", 9/16", 5/8", 13/16")
X-Acto knife
Small flat or triangular file
Phillips head screwdriver
Wire cutters
Wire strippers
Needle nose pliers
8x AA batteries
Double-sided foam tape

Step 1: Materials Collection

In addition to the kit:

Drill bits: A variety of drill bit sizes makes the project look cool, but requires some work to find the odd sizes. Sizes are: 1/4, 9/32, 13/32, 15/32, 1/2, 9/16, 5/8 and 13/16 inch.

Soldering iron and solder: If you are fairly new to soldering, try watching an instructional video on YouTube. It is well worth your time. This project requires a fair amount of soldering, but it is pretty easy if you know the right technique.

Drill press (preferred) or hand drill and center punch: You have to make some pretty precise holes. A center punch is a must.

X-Acto knife: Used to clean up burrs from drilled holes. You could use a utility knife or file or sanding paper instead.

Small flat file or triangular file: Used for making the rectangular cut outs and for cleaning up burrs.

Wire cutters, wire strippers and a small pair of needle nose pliers.

Phillips head screwdriver: Used for attaching the lid.

8 AA batteries: A set of alkaline AA batteries should last a really long time in this project. I don't recommend rechargeable for this project, because they don't have the shelf life of alkaline.

Double-sided foam tape: For attaching components inside the project box.
<p>Two things :</p><p>1) I can't find the four screws that fasten the top of the box (with the switches) onto the case. Can I buy 4 more from you?</p><p>2) I understand that some switches just change the way other switches work -- but I am not understanding how the switches I described can do anything if they are not completely wired into the circuit. What about the 3 missing jumper connections for the black momentary toggle? I have gone through the instructions carefully to see if I missed those connections, but I can see where that switch gets connected.</p>
<p>I finished the project, but there are some switches that don't do anything. One of the momentary switches, for example, doesn't have all its connections jumpered (and so doesn't do anything). What am I missing?</p>
Hey Steven,<br><br>The designer got back to me and said that all switches should perform a function. Some switches only change how other switches work. If there any more questions, email us at technical@jameco.com.<br><br>Best Regards,<br>Jameco Electronics<br>
<p>Hey Steven,</p><p>Glad to hear you finished the project. I was wondering which momentary switches exactly would be be referring to? I can ask the designer to double check in case he missed any steps or comments about them. Let me know when you can. Have a great day.</p><p>Thanks,</p><p>Jameco Electronics</p>
Look at the diagram for Step 31,32,33,34 -- you see the six wires from 'black momentary toggle'. As I read the instructions, only three of these wires get jumpered connections (both white wires and the lower red one). There are other switches that aren't doing anything, but this is the clearest example.
<p>I would love to see a video of this awesome project!</p>
