The first scratch-built component for my current project is just about ready. It is all soldiered (and yes, I've tested all the connections).
Next up is wiring up its partner and then linking the two together.
Structure supporting a large (approx. 7.5m x 5m) LED matrix display for road-side advertising. The display is seen by motorists on the Hammersmith Flyover. London Borough of Hammersmith & Fulham.

I'm currently using a Lilypad switched battery holder (w/coin cell battery) to power the LED. I'm hoping to switch over to the rechargeable battery like that used with the Lilypad Arduino, but need to find a connector for it that I can wire up somehow. But as a proof of concept, I'm quite pleased!

Tira de led flexible de 48 cm.
Sin regulador de potencia, esta tiene una característica especial, que por un lado se ve blanca y por el otro amarilla, lo que permite crear efectos como los que veis aquí.
Just some test shots with a new 10 watt LED! It's soooooooo bright! :) I need to set up a deep cityscape to show it off properly.
I make these framed, color-shifting LED light art things, which I have yet to come up with a good name for. The colors and patterns slowly shift over time: the two images in this set are taken of the same piece a few moments apart. The frame is spaced away from the wall so the reflection off the back of the canvas projects a "corona" on the wall around the frame.

LED wall lights indoor – Indoors of a house are just as important in appearance as the outside. In fact, some people might agree that the insides are more important and valuable. This is the reason why many of us decorate them with our heart. Some of the closest things to our heart are put...

An ATtiny13 uses PWM to fade 12 0603 surface mount green LEDs in and out, suspended from the PCB inside a jam jar. The ATtiny13 picks a random LED to flash each time, flashes it once, twice or three times randomly, then waits a random amount of time before flashing the next one. An incrementing counter is stored in EEPROM and used to seed the random number generator, leading to a different sequence each time the device is powered up via the switch mounted on the top. The LEDs are arranged in a standard 3x2 matrix which gives 6 LEDs, and for each position there is a second LED in reverse. The two column controllers are PB0 and PB1 as they can do PWM - another two LEDs could be added between PB0 and PB1 (and were on the prototype) but made the PCB design needlessly more complex: 12 is more than enough!
