Kicking off this campaign with a relatively straightforward 8-bit make-over. Love how the negative space arrow between the E and x translates into pixels.
I made these in about 1980 I think. You can actually buy these for real now. I was ahead of my time...
This was the first computer I ever used. If I recall, my Dad bought it in 1982 or 1983 -- which made me 5 or 6 years old at the time. It wasn't long after that I was learning BASIC. The last time this beast was powered on, everything was working except the space-bar. I also have a newer (cost-reduced) sibling to the 800 known as the 130XE. I'm happy to report that the 130XE is sitting next to me, functional, and sees some occasional use.
Strobist Info - PM7500EDF bounced off white foam board to the right and left of the 800. Looks like the small fill on the PM7500 was also on.
Some of the random 8-bit NES junk i've picked up here. The ? block is a portable speaker that also plays a Mario sound effect when you hit a button on top. The three diorama figures play short sound clips from the games pictured when you push the buttons on their bases.
A bit of 8 bit pixel art from Mega Man, in particular his classic foe, Iceman. Found in Central Sq, Cambridge in the alley next to the Central Kitchen, the piece proudly survived a classic New England winter with minimal damage. The wall around Iceman continues to change with new graffiti or murals regularly, but the painters respect the space around the 8 bit art and maintain its integrity.

Six of eight.
I might not do any tomorrow, my allergies are starting. :(
Thoughts?

The starry night(Vincent Willem van Gogh)
The image on the right is a close-up of the inside of an IRF230 MOSFET (a kind of power transistor), taken whilst the device was operating and running quite warm.
The thermal image was made using a Therm-App thermal imager with its 13mm f/1 lens at closest possible focus. To give an idea of scale, the diameter of the circle encompassing the 'works' is 20mm and the device measures 39mm in its longest dimension (not quite visible in the photo). The rectangular semicnductor device in the centre of the thermal image is about 2.75 x 4.5mm.
I was pleasantly surprised at the depth of field in the thermal image.
Normally, the 20mm circular area is covered by a metal cap but this was cut away to gain access to the device's internals. Thanks to G4JNT for this.
When the thermal image was made the device was passing about 2A with about 10V across it, dissipating about 20 watts. This is well within its specifications - provided it's bolted to a heatsink. It wasn't, so it got warm.
The diagonal lines visible on the thermal image are fine wires chemically deposited on the silicon so that current can be drawn through it. The small blue rectangle is the bond pad, where the connecting wire is bonded to the silicon die. You can see how that hair-fine wire cools the silicon, though that's only a side effect.
On the visible image the two round spots in the green dots are the lead-out wires, which protrude through the back of the device and provide connections to the outside world. A third connection is made through the metal of the case. In the thermal image the lead-out insulators appear hot but they're not: they are made of some kind of epoxy or glass that has massively higher emissivity than the metal that the rest of the device is made from.
This case style is known as TO-3 and a web search will turn up its precise dimensions. From tip to tip it's about 39mm. Likewise, a search on IRF230 will turn up a datasheet on the device.
The visible image was made with a Nikon D700 with a 28-80mm f/3.3-5.6 G lens mounted on a 48mm macro extension tube.
