Here’s the design for the interface: I’ll be sending this to OSHPark.com for manufacture.

0805 Capacitors / Resistors
Today I did a bit of soldering, and one thing that still amazes me is how small some components can be. I purchased some 0805 ceramic capacitors (0.1μF for those interested). These things are 0.08″ x 0.05″ (2.0mm x 1.2mm)! Even more…

Lights Controller PCB
The PCB for the lights controller is in! At OSHPark, you can only order a minimum of 3. Here they are: Looks like I forgot to label the ports on the silkscreen for the screw terminals. Oh well. I started…

Lights Controller Design
I did a quick design of the controller for the lights. It’s pretty simple: Everything connects to an ATMega328P (the heart of an Arduino) microcontroller. The RGB LEDs connect through some 100ohm current limiting resistors to the micro. If you…
LED Strip PWM
Just a quick shot of the LED strip in action. There’s an Arduino Uno controlling this with PWM (pulse width modulation) and some N-Channel MOSFETs. Some oscilloscope porn:
Kitchen Under Cabinet Lights
I’m starting a project to install under cabinet lighting in my kitchen. Most of the options at Lowe’s aren’t really attractive, to say nothing of the price. One major requirement is to use LED lighting to keep the heat under…
New Oscilloscope
I finally purchased an oscilloscope, the Rigol DS1054Z from Tequipment. It took a little over a month to arrive, but it works great, and is packed with features. It’s hard to believe that this scope was only $399!
