Either populate PLCC6-5050 RGB LEDs or single-color PLCC2 ones. The other 8pcs of small 0805 LEDs are completely optional. They can only be controlled as a whole set using a hardware-PWM pin on Timer0.

The moving average spikes... this is visible as a bright flash ;-( Very bad when fading - and that is the whole purpose of this exercise. www.picbasic.co.uk/forum/showthread.php?t=7393 www.picbasic.co.uk/forum/showthread.php?t=10564

1 to 3 modules with 32pcs 129 lm/W nichia leds each. LED driver: MBI5168, brain: ATtiny2313. There seems to be a decline in brightness in the middle of the workspace when turning on more modules. I don't know if that is an effect of the camera's exposure program or if I should have used thicker wires for the supply.

Depending on what type of RGB LED you have, make sure to orient it properly. Use a DMM / diode tester in case of doubt.

Formation history is still somewhat unclear, but there are strong hints that a giant pair of tweezers might be involved.

Just recently an ancient and seclusive civilization of strange individuals was discovered. The fiercely service and believe in a god called OHM. Nevertheless they are quite often heard talking about de-coupling. It is only assumed that it can't be related to their relationship with their god. Their secret sign is the Greek Ω

Building blocks of a world of its own.

This is what I got . I wonder who will get my boards ;-) The top one is an 'Arduino Nano V3.0'. I do have suitable ATmega168 chips, headers, probably LEDs and capacitors, but neither do I have an SMD USB receptacle nore the FTDI chip. The bottom board is a breakout for the FTDI FT232. Assembled versions can be found in their webshop. There's also a thread on the dangerousprototypes forum about this service.

Solder the LED drivers. Make sure orientation is correct to prevent terminal damage.

The AVR controls the brightness of the LEDs using 'BCM'. This gives a 6-bit resolution per color channel. This printed circuit board was ordered at Seeedstudio and uses traces as narrow as 6mil. It also works with a slightly modified version of the Arduino ShiftPWM library. That delivers extra-smooth color fading.

Solder the LEDs. Turn down your temperature to about 250°C and use proper SnPb 60/40 solder.

Inspect the board. This printed circuit board was ordered at Seeedstudio and uses traces as narrow as 6mil.

Solder down the microcontroller first. Use plenty of flux and check for proper orientation and alignment.
