Also visible, the motor and gearbox that provided the lifting feature. See it in action www.youtube.com/watch?v=7eunXxowqcQ

For years, I have purchased Apple products from Small Dog Electronics because they were recommended by my daughter Jessamyn. They turned out to be as helpful as she said they would be. However, I had never been to the store before this week. Everything had been done online or by telephone. Yesterday I finally had the chance to visit the store in person. They were really great--good service, unintimidating, and helpful. I refrained from telling them that my brother was now the new voice of Apple products online, because I didn't know the ads had started to run yet, but they have.

Dirty Electronics Mute Synth custom modified by A.S.M.O. for Daniel Miller (The Normal / Mute Records).
Touch panels hardwired to pots and switches, 3 LFOs, one for each oscillator and feedback.
Low / band pass resonant filter with external voltage control input, self oscillates at full resonance.
Panel is covered in (warm) leatherette, nice!

General Radio Type 687 Electron Oscillograph.
This was the first successful commercial oscilloscope ever. GR made one model before this, but they did not sell more than a handful. They made one more model after this, but did not market it effectively.
The only other oscilloscopes made before GR's three models were custom research instruments not sold as commercial products.
GR's oscilloscopes predated Dumont, Tektronix, HP, etc.
This one is rather beat up, but entirely restorable, even the broken shafts. It contains very little electronics (no vertical amps for example) so after replacing a few very old capacitors, it will probably be fully functional.
uC prototyping blocks, aka "Dev Blocks." These are small single component boards that are ready to plug into a breadboard.
Here the connectors are interlocked.
From left to right:
Piezo element
Bi-color LED (red/green) x2
SPST, N-O momentary switch w/ pulldown resistor
Light dependent resistor (LDR)
DS18B20 I2C digital temperature sensor
LM35 temperature sensor (10mV/C)
Finally got the nerve, after my soldering class, to finish putting together the kit I got sooo long ago. It was easier than I thought.
Here you see the almost-final step of Lesson 3 in Ladyada's Arduino tutorial.
The circuit and PIC code are from www.electronixandmore.com/nixieclocks/3.html
It flashes the digits in order, then pauses, then repeats.
My first test with the pan-tilt servo unit.
Next up is finding a way to power and control a small fan attached to the end of it and finding a way to control a minimum of 5, but preferably X, more from one Arduino, I've found some links that look promising.
Tools to the right, parts to the left. My workbench has two modes; overly organized, and chaotic + crowded. When I dive into a project, there tends to be five or six working 'threads' competing for resources and attention. Each subtask takes on a life of its own, and the clash of these efforts looks like this. Trust me though; it's a symphony, and my mind is in a focused fugue-state when I'm buried in this. Amusingly, the various steps and components each have a distinct synesthesia-esque voice in my head. Sadly, I get occasionally interrupted by real-life (tm) and then it all comes crashing to a halt and sometime later I have to painfully rebuild that original mental state in order to have *any* hope of remembering where all these tiny parts came from. Its like coding or math. This is why I photograph, sketch and document project steps so obsessively.
Circuit board from a dead VTech cordless phone. Strange metallic colour due to the camera making weird decisions about the exposure.
Printed circuit board that should be equivalent to the breadboard that displayed The Eight Colors. It'll be much smaller and neater, about two and a half inches square and with a minimum of actual wires - it'll be mostly low-profile surface mount stuff like on this board.
It's a bit goofier than most boards I make, because I think the recipient will appreciate that.
Everything is mirror-image because you have to do that to get the boards right. What you see here gets laser-printed onto the Special Blue Stuff, then applied face-down to the bare copper circuit board and ironed on. When you peel away the Special Blue Stuff, you're left with a mirror image of what was printed, which was a mirror image of what you wanted, so you end up with what you wanted.
I have a terrible grasp of visual/spatial stuff, so I always have to walk myself through that concept.
