Sparkfun has recently released a bevy of new boards and other devices, with some very intriguing new builds among them.
The first board that caught our attention is the Wee. It is a compact Arduino compatible controller that features a small size, low voltage, and many other minimalist attributes. It is built around an ATMega 168V and uses all SMD parts.
For even tinier fun, check out the LilyPad LED. It is a LED designed to be incorporated into clothing, featuring large holes for threading, a thin and extremely small PCB and a very bright 250mcd light. It is also washable, meaning that one or many can permanently be incorporated into clothing without fear of losing them. You can see these in the turn signal jacket we covered earlier.
The last one we’ll discuss is the LiPoly Charger, a USB lithium ion battery charger. Based on the Max 1555 IC, the LiPoly can use USB bus power or a 2.1mm center positive wallwart power(it uses the more high-powered wall-wart if both are connected). It can’t charge NiMH batteries, but it is still compact, efficient, and very useful.

really loved the lilypad led.. there are so many ways to play with it.. intertwining your sewing with thin metal wires and arranging the lilypads on the wires would allow powering from a centralized source.. it would be really cool to emanate light from different parts of your sweater for use in dark places..
The Wee product number (and link) is incorrect. The correct URL is Wee
the wee link above points to the wrong product (a biometric monitor). The wee is “products_id=8737”
anyone know the voltage for the lilypad led? it didnt say. it would be sooooo sweet to put those in clothes or all over your bike or car…
Did you guys see that linear actuator ? Based on muscle wire? nice…
kvmanii: quick digikey search says a 250mcd white LED is ~3.3Vf. In the pic you can see a 100 ohm resistor.
So 5V to this would result in 17mA led current (which is close enough to 20mA, fairly standard value).
