Solar Cockroach 2.0

Solar Cockroach 2.0
Awhile back I made a little instructable on how to make a simple Solar Cockroach virbobot out of a 1.5V solar cell and a little vibrating motor. People seemed to enjoy making them and I enjoyed giving them away as odd gifts to my friends instead of buying them real birthday gifts.

All was good in the land... until someone in China decided to stop making the little 1.5V solar cells AND the very efficient little motors which were the backbone of our vibrobot. Sadness fell on many a basement workshop. Little motors all over the world stopped vibrating.

Well after a bit of searching replacements were found! A better, and slightly more cockroach sized, solar cell was discovered and tested. A more powerful and flexible motor was bought. Now all those Solar Cockroach lovers out there can get back to making what they love: lead solder covered children's toys.


In this instructable I'll be showing you how to put together a Solar Cockroach. As stated above it's a small vibrobot that uses a solar cell to power a little vibrating motor. It's easy to construct and makes a great gift. How easy is it? I had my neighbor's 13 year old son put one together, and he had never soldered before.

Time: 15-30 minutes
Cost: $5-10
Difficulty: Easy

Step 1What You Need

What You Need
«

  • solarroachv2-01.jpg
Supplies:
1x 2V Solar Cell
1x Vibrating Pager Motor
1X Resistor or diode, or other bits of scrap wire.
2x Big Paper Clip
2x Googly Eyes
Magnet Wire

Tools:
Soldering Iron
Solder
Hot Glue Gun
Wire Cutters
Helping Hand - (Optional, but really... handy)

Where to buy:
You can find these 2V solar cells all over the net. eBay has quite a few people selling them in bulk. You can really use any cell you want, but the big factor is the size. The 2V work well in this case though a small round cell would be fun to turn into a Solar Ladybug.

You can buy the vibrating motors all over the web. They come in various sizes or shapes. If you have an old cell phone or pager you can steal the vibrating motor out of it. This will save you $2.

I sell completed Cockroaches as well as kits on my website, BrownDogGadgets. I also have a variety of solar cells and vibrating motors if you're in the need.

As I said above, you can easily buy or salvage most of these parts.

What's the motor for?

Just so you know roaches have 6 legs, as do all insects. Regardless these are really cute. I want to make one to bug my mom.

not to be mean or anything, but resistors are kinda expensive.
to cut off the wire of the thing just to get the wire is something I woudn't do


I guess it all verries from person to person.

yeah,(no offense, Radioshack), I relized Radioshack isn't exactly the best place to buy matireal.

I once built a beatlebot and bought stuff at Radioshack and the thing ended up costing $34.00!

(you must be going insane now)
how much do "Helping hands" cost?
Nov 22, 2011. 3:55 PMhrodriguez7 says:
Okay!
Thanks for tolerating my comments

I like this idea for my first bot project. But I can't seem to find the blue-cased motor that you recommend. Are there any others that fill the bill? Or can you tell me how to identify the desired motor if I try to cannibalize a cell phone or such instrument? Thanks.

( i hope you're not annoyed with all my comments)
I still dont understand why you can't use the motars that already have wires
Nov 9, 2011. 5:47 PMhrodriguez7 says:
in the kits that you guys sell, do you pack inthe kinda motars that your using,
or the fancy blue ones.

Any idea if these blinky solar keychains produce enough juice? I see them sold quite cheaply at retail or given out free as promotional logo items. http://www.greenbaba.com/Solar-Gadget/C011-Solar-Key-Chain.html

First thought: the Orang Asli kids will like this! My friends and I are visiting (every few months or so) some rural indigenous people's communities that aren't connected to the grid. Their school's only power source is solar panels so we have been trying to teach them about solar. This might be a fun toy for a hands-on workshop to show them how electricity works and basic assembly techniques.

Awesome job, Josh!

nice little robot I gues I could build it in 5min but it would be more fun if cockroach would go into dark (like thay usualy do), that would be two morors to photosensors and some forward directing bristle legs, I gues that would be the 3.0 version.

I like the simplicity of this project! It's so easy that it could be built by a 1st grader while still being a satisfying project for an adult! love it!
