Old radio made of bakelite. A Philco Transitone from 1948.
Lava lamp still works. Radio would take some repair, but I bet it could work too.

Almost ready to test.
Input is 50V p-p AC from a wall wart. Output is ±1–24VDC (trimmer adjusted) regulated by a standard LM317/LM337 circuit.
Pins underneath meet the pair of rails on a standard breadboard.
Both regulator circuits were tested on the breadboard first, so I'm just looking for soldering and wiring errors. And I need to add the 2 x Cadj capacitors and one diode to feed the negative smoothing capacitor.
The Adafruit protoboard is only just big enough…

PARTS
• 2 or 3 12-position rotary switches (or 10-position, whatever you can get)
• 2 pin or banana jacks (to match your test leads)
• resistor assortment from 5 ohms to 1M or greater; gold bands (5% tolerance) are better than silver bands (10% tolerance).
• project box
INSTRUCTIONS
1- Get a box and drill holes for mounting two or three 12-position rotary switches. Drill holes also for the two jacks.
2- Mount the switches and the jacks; label switch positions with corresponding resistor values.
3- Follow this diagram and solder resistors directly to the lugs of the rotary switches.
NOTE: If you solder the resistors so their unsoldered leads extend the opposite direction of the switch's shaft, these leads can be gathered together and soldered at once, connected to the bus wire terminating in point "A".
• The first switch would provide the lowest resistance, the next would provide mid-range resistors, and the final switch would be wired to the resistors with the greatest resistance.
• As seen, the 12th lug of the depicted switch connects to the next switch in the array. Naturally, the final switch in the array would have its 12th lug connected to the final resistor in the matrix.
PANEL
To mark the panel for the resistor values:
1- Turn the mounted switches to position "1" (doesn't matter at all how you orient the switches, just turn them to their lowest resistor settings).
2- Place knobs loosely on shafts and turn their pointers to wherever you want "1" (your lowest resistor value) to be located around the dial (near top or bottom of dial, usually).
3- Once all pointers are angled to this position, tighten their set screws to keep them in place.
4- With your marker, put dots where the pointers point as you click them all around their orbits.
5- Label these dots with the corresponding resistor values. Position "12" can be marked with an arrow pointing to the next switch.
USAGE
1- Set all rotary switches to "12" for starting position. This will provide the greatest resistance available (this is safest on the circuit). Plug your test leads in.
2- Begin turning the LAST dial downward and observe the response of the circuit (LED brightness, audio output, circuit clocking - whatever you're after).
3- When you get to position "1" on this switch, turn the next rotary switch to position "11" to continue the resistance decrease, and so on until you reach the resistance value desired.
4- Observe the resistance the dial is pointing to; grab another resistor of the same value, and your green LED will never again scare you with that ember-like, off-yellow, over-voltage, "Seeya in LED Halvala" glow.

A pair of cufflinks made out of some spare ICs. They were suprisingly quick and easy to make.

My solder joints are looking a lot better now that I have a good soldering iron (Weller 25W) and smaller solder (0.32mm versus 1mm).
No, this is not the Google Earth view of some city. It is a macro of a silicon wafer containing VLSI circuits. Each of those blocks is about a centimetre on each side and contains numerous transistors.
Thanks a lot to my friend in our university's VLSI lab for allowing me to take this photo.
I bought this used from KEH.com. It was listed in EX condition. It looks pretty good other than a few scuffs on the top of the camera.
