Cover up.


Accelerometers, Gyroscopes, Temperature Sensors, Pressure Sensors, ...

Switches and Relays

Turn things on and off.


Make thing move. We include some circuits/chips for driving motors


GPS, Mobile Phone, RF Transceiver, Bluetooth Modules, ...

Popular Parts

So many parts to pick, but which ones? Why not pick a popular part, or a group of parts for areas of interest?

Component Manufacturers

Links to homepages, phone numbers, contact info, ... There is often info under each component as well in the components sections above.

PCB Manufacturers

contact info, PCB trace width/spacing capability, ...


Good places to buy, numbers to call, people to talk to, ...

Get your low cost motor controller boards & motor driver ICs

Free Samples

Free is nice.

Free From Salvage

Dig in, to the free stuff, a list of links and a bunch of ideas on how to use your loot.

Salvage Ideas

Unusual ideas for the fruits of your labor.

demo board

Lots of people put a microprocessor and most of the other essential stuff on a tiny little demo board, easy to plug into your solderless breadboard (or your custom PCB) that has just a few more things that make your project special.

data sheets

You will want data sheets for you parts. Check:
