LED lamp software

I don’t even have the SOIC-8 test clip so I can program it, but between a couple hours last night and an hour tonight, I’ve already written most of the code for the ATtiny13. One thing I like about the AVR microcontroller is avr-gcc and avr-libc. It makes for really quick development using tools I’m […]

LED lamp, done making boards

Though I have a cold, I had to do something with my time (such is life without a TV), and I redesigned the board and etched this: This is a project of firsts. Not only my first time designing PC boards, but my first time soldering surface mount devices. I put everything except the ATtiny13 […]

Working on a third board rev…

I got the parts for my LED Lamp project from Digikey today. Once I got home from work, I decided to engage in the relatively relaxing and quick task of verifying that everything fits the pads on the board and the board layout. Most of it is okay, but a couple things are wrong: I […]

Second LED lamp board

From my comments on the flickr post: All hand-routed this time. The more I get familiar with the particular board layout, the less the autorouter impresses me. [The second image is] with jumper in place. I laid it out as to use a 1206 zero ohm resistor, but since I hadn’t ordered any, I just […]

LED lamp, PC board design, soldering stuff

I’d been working on the LED lamp design. I have the circuit design basically done, and I’ve been spending my free time in the past week learning Eagle CAD and designing the board. It’s quite a learning curve, but I’m also satisfied that this software can do what I need. Here is my first board […]
