Mini RGB controller kit.
Visit the project page.
An awesome miniature RGB controller that uses an 8 million bit randomiser to select from over 16 million colours and has a multitude of really smart effects unmatched by any other controller anywhere near this price. It can sink up to 5000mA (5A) per channel and is designed to run from a 10 to 15V supply. Check out the project page for more details.

Mini RGB controller kit £8.95 each.
Mini RGB LED pixel kit.
Visit the project page.
A really neat little kit for making a 12V RGB LED array. It is supplied with good quality diffused LEDs to give extremely good colour mixing. Ideal for moodlights and other projects when combined with one of my controller kits.
Mini RGB pixel kit £2.85 each.
Sign PCBs.
Visit the project page.
PCBs that let you build LED signs that can be operated from batteries or a power supply. One PCB is used per character with a standard 5X7 matrix used for standard characters and a narrow 3X7 PCB used for narrow characters like "I" and "1".
These PCBs are supplied blank for you to fit your own choice of LEDs and resistors. See the project page for more details.
Visit the project page.
These PCBs can also be used to build low voltage LED floodlights.
The pricing has been set at full quantity discount on the basis that most applications will require several PCBs.
STANDARD 5X7 sign PCB £1.95 each.
NARROW 3X7 sign PCB £1.75 each.
RGB CONTROLLER CHIP
View the data sheet.
New software May 2009 (green release).
A chip dedicated to the task of generating cool colour changing effects with RGB LED lighting.
There are 26 sophisticated programs with up to sixteen speed or colour options on each. These range from psychedelic colour strobing through to very smooth and dignified architectural colour changing with a massive pallete of over 16 million colours and a randomiser that produces a continuous stream of over 8 million data bits for truly random results.
Don't confuse this chip with the tacky colour changers that just go through a very short repetitive colour routine. This chip has a virtually endless array of subtle colour moves in a range of colour palletes.
Just to add the icing to the cake, the last program settings are stored to non volatile memory so that the unit always powers up in your favourite mode.
The tech specs are equally impressive with a very low component count, a PWM frequency of about 350Hz and an intensity resolution of 8 bits giving each colour a range of 256 intensities.
The output capability is 20mA which can either be used to drive a few LEDs directly for ornamental applications, or used to drive power switching components like Darlington transistors or MOSFET's. The chip incorporates weak pull up resistors for the program selection buttons.
RGB chip £2.95 each.
Pack of 10 RGB chips at 10% discount £26.50 (£2.65 each)
Pack of 25 RGB chips at 20% discount £59.00 (£2.36 each)

FULL RGB CONTROLLER KIT
Visit the project page.
New software May 2009 (green release).
No other programming equipment is needed to set this controller up. All software is already on-board!
They say that simplicity is reliability, and that was certainly the design concept behind this kit. It has a very low component count, but still somehow manages to put multi thousand dollar architectural lighting systems to shame.
It's a true "fit and forget" device. Once set with your preferred options it will always power up in the correct mode for the life of the installation, or until you make further changes.
This module can drive up to 5A (5000mA) per channel making it capable of driving literally thousands of LEDs.
This quality kit uses professional grade components throughout, from the gold-insert turned pin socket and rising clamp connectors to the good beefy MOSFET output stages.
The board is manufactured in FR4 laminate and is fully tinned and screen printed with a solder resist mask and component placement data for all the components supplied as shown above.
A set of four mounting feet and matching fixing screws are supplied for mounting the module in your desired location.
Refer to the controller page for assembly tips.
This kit is used extensively around the world in theme parks, architectural features, fountains, sculptures, trucks, cruise ships, rides, bars, moodlights, clubs and many other applications.
RGB controller kit £14.85 each.
Pack of 5 RGB controller kits at 10% discount £66.80 (£13.36 each)
BARE MR16 SUPERFLUX PCB
Visit the project page.
Get some cheap LEDs at Phenoptix.com.
A very nice PCB designed to fit into standard MR16 downlight frames (12V 50W downlights). It is designed to take nine superflux 4-pin LEDs (3 or 5mm lens) with either three of each colour for RGB colour mixing, a cluster of nine of a single colour or even a random combination as you please (red and blue mix looks good).
The board has four resistor positions with one each for the green and blue circuits and two in series for the red circuit to spread the heat dissipation due to the lower forward voltage of reds.
The board is manufactured in FR4 and is ROHS compliant with the extra touch of gold plated pads making it very easy to solder. There are four pads on the back for wire connection R,G,B and +. For single colour use just bridge the R,G & B together.
Each channel has three LEDs and a resistor in series and the PCB is designed for use at 12V.
MR16 PCB £1.35 each.
MR16 PCB £6.25 for five.
MR16 PCB £11.00 for ten.
LARGE BARE SUPERFLUX PCB
Visit the project page.
Get some cheap LEDs at Phenoptix.com.
An excellent PCB that is designed to fit into a standard 150W halogen floodlight case. It can either accommodate 18 each of red, green and blue superflux LEDs (3 or 5mm lens) for colour mixing with RGB controllers, or 54 of one colour.
Other applications include low energy (solar) lighting, vehicle lighting, emergency lighting, outdoor lighting or Hydroponic red/blue grow lights.
An all green version looks fantastic for spooky halloween FX!
Large superflux PCB £2.95 each.
Pack of 5 large superflux PCBs at 10% discount £13.25 (£2.65 each)
Pack of 10 large superflux PCBs at 20% discount £23.60 (£2.36 each)
FULL RGB KNOB CONTROL KIT
Visit the project page.
Back again and supplied with the new software! A knob based RGB controller kit for colour mixing with LEDs. This kit is different from the other controller in that it uses a single knob to choose colours and enable the automatic modes. This kit is perfect for controlling the LED panels shown above.
I've upgraded the software for this dramatically. It can now access variable colour temperature white with the knob, has a calibration mode to match red, green and blue intensities, has a "favourite colour" mode which can recall a programmed (full spectrum colour) with a single press of the knob and has two automatic modes which pick colours randomly (solid or full spectrum) and gently fade between them, pausing on each one momentarily.
Once again everything is done in gentle sweeps, and the unit remembers the last mode it was in even when tuned off. All the features you'd want in a basic architectural lighting controller.
RGB knob control kit £16.85 each.
Pack of 5 RGB knob control kits at 10% discount £75.80 (£15.16 each)
Knob controller software upgrade chip
The new software for the knob controller (supplied with new kits) that adds variable colour temperature white into the colour range, allows calibration of the red, green and blue intensities for perfect white, lets you choose a favourite colour for instant access at a single press, has two automatic modes, one with bold colours and one with full spectrum colours and last but not least, a facility to set all parameters to their defaults.
As before, the last mode is always remembered for power-up.
RGB knob software upgrade chip £2.95 each.
