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.

My first PCB: a breakout board for ERNI's MagJack.
I had to design my own part for this as I couldn't find a library for the jack. Once you get the hang of it, it's not that tricky. Once that and the design part were taken care of, the rest was pretty smooth. I used paper of a recruiting handout from a university to print the toner transfers. It worked out pretty well (I did have to make a few corrections – sharpie, exacto). I wasn't sure what to use for drilling, so I used a small conical shaped diamond bit with a Dremel. It too, worked out pretty well. I have to say I'm really happy of the end result and will not hesitate to do it again.
A riddle one of the EFF staff has in their office.
Can you figure it out?
To start off, there aren't any hidden wires, it's a single wire running in series through both switches and both lights.
However, each of the lights is controlled independently by it's own switch.
How does it do it?

What I packed for five months in Ecuador and Peru. I'll primarily be farming, but also hiking, camping, swimming, sightseeing, and just plain adventuring.

Electronics/Paper:
3 copies of my passport
6 small Moleskin notebooks for recording thoughts, experiences, and plans (instead of blogging)
1 copy of my immunization record and driver's licenses
40 photos that I took the last time I was in Agua Blanca and would like to give to the families and individuals that I became friends with there
1 iPod (with charger and headphones)
1 iPad with Otterbox case (not pictured because I'm taking the photo with it!)
1 Camera Connection kit so I can upload my photos from my camera to the iPad
1 Olympus Tough camera with case
1 travel alarm clock
1 GPS Spot device (to ease my parents' worry a little bit...)
1 little Maine case to remind me of my roots and keep this stuff organized
3 chargers (iPad, camera, Kindle)
2 spare camera batteries so that if I'm away from electricity I can swap them in and out
1 Belkin power strip
2 reading lights
1 3G Kindle loaded up with new (and old!) books
This is the first prototype PCB for my LED firefly concept.
For some reason, despite extensive checking the PCB was completely mirrored when transferred it onto the board, it looks like printing from an exported gerber is the problem here. This sucked!
However I'm not one to waste a perfectly nice PCB, so I took the ATtiny13 and bent all the pins over, mirroring it, then soldered that down and came to my LED.
Here I had a real problem: all the pads are on the bottom normally, so now they'd all be on the top. For three connections, I was able to make a giant solder bridge, but for one of them there wasn't enough space so I managed to make a jumper wire. That was crazy soldering! I somehow got the resistors in place too.
Sadly the LED points into the board, but you can still see what colour it's trying to pull off.
I then went to program it and for some reason the ATtiny13 wasn't responding at all. Probably static or broken or something crazy. I checked all the connections but they were all good, so in the end I took a second ATtiny13, bent all the pins on that as well and soldered it on top of the first ATtiny13.
This worked (amazingly), so I now have a working prototype board - with a deadweight ATtiny and an LED that points into the board, at that.
I also had to tape over a track that was shorting the button cells, damn inaccurate silkscreens! Oh well.
By the way, the random wire is for a nice random seed when read using the adc.

An unattended radon detection and data logging instrument I built for work. I know... I accidentally installed an under-board SD card slot on the top, so the cards have to be put in upside down. That's embarrassing...

When traveling, I go through a rather thorough, yet painful process of figuring out what the heck electronics I should take along. On Saturday, Sara and I will be traveling to Finland and Sweden, so the process begins.
Here is most of what I use today in terms of portable electronics, from the white lens in the upper-left, spinning counter-clockwise:
Canon Lenses
Cameras
Polaroid t833 waterproof
Canon 7D (not shown.. used to take picture)
Phones / portable music / Readers
LG Rumor Touch (Sara's)
HTC Evo 4G
iPod Touch 2Gen
iPpod Touch 4Gen
iPod Nano 1Gen
iPad 2
Kindle 3rd gen WiFi (black)
Kindle 3rd gen WiFi (Pink, Sara's)
Computers
15.4" Dell Studio 1537 (Sara's)
12.1" Dell L attitude D420
Flashes
Canon 430 EX (not shown, bounced off ceiling for photo)
Canon Vixia HF100 Camcorder
Media players / photo dumpers
Vosonic VP8390 160GB
Vosonic VP6230 120GB
GPS
Whew! So traveling, sort-of light, I'll take the Canon 7D, the 24-105, 10-22, 28mm and the 50mm. Only one flash, a 430ex as I don't plan on shooting much with flash. Canon S95 is small and does video, so that's going. Polaroid is not needed as we aren't going in the water. My phone is a necessity (though it's CDMA, WiFi makes it very useful for everything but phone calls). Ipod touches will stay back for Ian (so we can do Facetime w/ the iPad 2, which we will take). Kindles come along as does my laptop. May take both Vosonics for redundant photo copying, camcorder stays as does the nuvi (not taking a car), but Oregon goes for geocaching and general navigation. If you actually made it this far, congrats, you are a nerd.
A power supply, a soldering iron, two crappy but one is at least serviceable multimeters, a hot glue gun, and various other tools.
I got 12 IN-14 nixie tubes from Russia sometime in June but haven't had /any/ time to play with them since then. I've finally got around to etching the PCB I designed for a power supply - it goes from 9VDC to 170VDC - and so today was the first test.
I'm delighted to say it worked first time (though I did have to add in a resistor I forgot to include in the design).
I also found out that these nixies have decimal places! I never knew that.
The next step is making a system to control all 12 at once, which will probably need a few of these power supply modules to get enough current flowing. I plan to integrate that with an RTC to show a DDMMYY/HHMMSS clock, but maybe I'll think of something more inventive first.
