Just the SMT transistors to add on the back. Hand soldering the TQFP AVR microcontroller was interesting.
PCB through the excellent DorkbotPDX batch PCB service (nice colour)!

I just love that sparkly background liquid-crystal displays have! A camera flash brings it right out, too.
I've long wanted to learn how to use graphic LCD modules. They're fairly cheap liquid-crystal displays designed to be used in a variety of devices, and it's very likely you've seen some of them just like this one used in equipment around town. For you other Salt Lakers out there, I'm pretty sure the gas pumps at the Costco on 3rd West and about 17th South use displays like the one pictured here.
Your laptop screen or desktop flat-panel is the great-great-great-etc. grandchild of the generation of displays this one belongs to. The heart of this one is a chip called the Toshiba T6963C and I think it was designed in the 1980s. Though this individual display was built in about 1998, it has a very 1980s feel to it - very slow drawing and capable only of black and white. T6963C-based displays can show some simple clunky pictures - I think you're required to make them display Tux the Linux Penguin at least once or they take away your geek ID card.
For me, these displays were demystified by the T6963C Rosetta Stone by Steve Lawther. Mr. Lawther, a helpful British guy - sorry, bloke, designed a straightforward test circuit for these displays around ten years ago. I get the sense that many if not most electronics hobbyists who have used displays based on the chip have started from his design. The test circuit is based on an obsolete MCU, so I ported his code for a newer chip and (as they say across the pond) Bob's your uncle.
His test code didn't include a checkerboard screen like this - that was my own contribution, because I like checkerboards.
I'm not sure what I want to use these displays for just yet, but I dig knowing that I can in fact get them to work.
A 3.3V 8MHz Arduino Pro connected to an XBee Series 2.5 and a battery. The other Xbee is on the Sparkfun Explorer USB and connected to a Python program that responds to the Arduino's calls.
The long exposure shot lights up the LEDs :o
Once this component guided microwaves, now it's headed for the aluminum scrap heap. Old electronic devices in the Knox College physics department are disassembled for recycling by faculty member Tom Moses.

Vintage passenger service modules , called APAX, from passenger aircraft. These modules are located under the seats and provide music and other passenger services, as steward call feature.
Closeup on the first tests with the pulsar toner transfer paper and my new GBC H212 laminator. I'm not quite happy with it. The lines + spacing are 0.25mm and I had to run it through the laminator about 15 times. I'm starting to doubt whether toner transfer is such a big saver of time/work compared to the usual photographic transfer. OK more chemicals involved, but NaOH doesn't stink and is much cheaper than a laminator and with the right UV box, it's painless and gives 100% result.
