Just playing around a bit with a CCFL tube I stole off a "hip" computer fan and I managed to capture these great pictures. These photos were taken with a cell phone camera. I'll have to get Laura to take some higher quality shots, this is fun!
Well technically this project isn't really my first PCB. That was made back in high school, a 555 circuit that made an incandescent bulb flash. Excitement! When I first sat down last year thinking about making PCBs again, my first thought brought me right back to that etching process. I'd heard of a technique called "toner transfer" that can be used to create boards at home. However, I have 2 cats and a wife in an apartment to think about here. I don't want to leave lots of toxic stuff laying around the house for the cats to eat and for everyone to breathe. So, I decided to use an online printed circuit board fabrication house where I can submit my design and get back a nice board without messing with toxic chemicals.
I was fiddling around with an AT90USBKEY demo board ($29.99US from digikey), and Laura walks in with a Myntz! case that someone gave her. I'm looking at this thing in my hand and the case she's handing me and, WOW this is really close! So I get out the old awl and punch a hole in the side. I use the smallest key on my keychain to widen it some. Voila! Instant case!
Aww! Just think of all the awesome things I could have done with 15 LCDs!
Everyone's happy today! Came home from work and my new FPGA board has arrived. |
