CLASSIC ENGINEERING TRICORDER (Static Prop - non working)
This is something I came up with and put together. I noticed that in the original series Scotty would sometimes carry a tricorder with him -in particular the episode "The Doomsday Machine" I figured this had to be some kind of a special engineering tricorder (like the geological tricorder) or at least programmed for that area (like the medical tricorder)
Being a prop enthusiast, I though a "special" engineering tricorder would be more interesting then an average-looking task programmed tricorder. Since we never saw Scotty's tricorder opened to the camera to see any of the details, this gave me freedom to create a special unique face for the middle section similar to what had been done for the geology tricorder.
The main tricorder body was from a garage kit by Marco Ent.
I added a small secondary "false" engineering screen on the right side and 3 extra tricorder buttons on the left with a "false" side lever switch on the bottom and 3 light indicators (one green, one red, & one blue rectangular) on the top. I also made an engineering graphic display for the main top screen.
Now I have a one of a kind tricorder. No electronics, but still looks cool!

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.

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)
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.

Finally got my hands on the MB-23 battery grip for my F4 (now F4e).
Just like my F4, came boxed and mint.

The Nikon F4 was a 35mm autofocus (AF) single lens reflex (SLR) film camera, first introduced in 1988 as the next generation in Nikon's line of F series professional cameras. With industrial design by Giorgetto Giugiaro, the F4 was the first professional Nikon to offer autofocus and is able to accept any of Nikon's manual focus (MF) or AF lenses from 1959 to the present day, including the two F3AF lenses (in Autofocus mode). The F4 replaced the F3, which was a manual focus camera produced from 1980 until around the year 2000. Nikon introduced its next flagship model, the F5, in 1996. All F4 models were discontinued soon after, in May 1997.
The F4 introduced many Nikon owners to autofocus (as well as focus tracking), and was the first professional Nikon to utilize a vertical-travel metal-blade shutter (with shutter balancer to minimize noise and camera bounce). As a fully electronic camera with motorized film transport (up to 5.7 frames per second), it required one of three available bottom-mounted battery packs to operate, using standard AA or rechargeable cells. For the first time on a Nikon SLR, two of those battery packs also offered an additional vertical shutter release button and grip for using the camera vertically.
Its controls were transitional between those of mechanical SLRs and future professional film and digital SLRs: the F4's electronics, LCD viewfinder display, autofocus, programmed auto-exposure, and matrix meter looked to the future, but it also retained classic dedicated analog dials for shutter speed, lens aperture, metering pattern, and exposure compensation.
The F4 was the first Nikon F-series camera to lack a manual film-advance lever, though it offered both motor-driven and manual film rewinding. Like previous F-series cameras, the F4 featured a high degree of customization to specific tasks, with various remote controls, film backs, and viewfinders available. While it was a complex camera with over 1700 parts, the F4's high-quality mechanical and electronic components, as well as weather sealing and tough construction, made for a reliable and long-lived professional SLR.
The F4 will accept all autofocus lenses made for the F mount, as well as almost all manual focus F mount lenses excluding some very early fisheye lenses. The meter coupling cam can be moved out of the way for use with lenses manufactured prior to 1977 (non-AI lenses). The F4 is one of the few Nikon cameras offering full Matrix metering with AI manual focus lenses.
Its lack of electronic aperture control limits the F4's functionality with G type lenses, which do not have an aperture ring. With these lenses, exposure control is limited to program and shutter-priority modes. In addition, DX lenses are not designed to cover the full 35mm frame and will vignette when used with the F4 (or any other 35mm camera). The F4 also provides no support for Nikon's later VR (Vibration Reduction) system; VR-equipped lenses will mount and function, but without image stabilization.
Eventually Nikon had three F4 models that were distinguished by which integrated battery pack was attached. All F4 bodies are interchangeable with all battery packs. Therefore none of the cameras includes a label for its particular model name—all use a simple "F4" nameplate:

Bright/dark LED triggering off PS3Eye VSYNC for eye tracking.
The bottom signal is the VSYNC off the camera, the top is the toggled output from the 7474. This is zoomed into a single VSYNC clock pulse.
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.

It flashes the digits in order, then pauses, then repeats.
Components all laid out with solder paste. The big square chip there is the expensive accelerometer. It's kind of freaking me out because there's no real way to apply solder paste by hand for the tiny pins — you basically need a stencil or something. So, I took the advice of those more experienced and did a trick where I applied a tiny-tiny amount of solder to each pin — basically a pin-prick of solder+flux. That was a bit messy the first time. The second time I was a bit better. And I got to try a third time because on this board (SFE — Sparky) I completely misplaced the chip — I had it turned the wrong way, which was a really dumb mistake. So, I had to remove it with hot air, and then clean up the mess, then reapply pin-pricks of solder, then heat it on again but with hot air.
In Sacramento, on Del Paso. Closed recently, would make a good store for someone.

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.
