Mounted ZX Spectrum tape covers.
Mounted front panel from a dead, vintage audio amp. Holes are backlit with LEDs and the dials cycle up and down. You can control the speed and lighting by touching the wood on top of the frame - a capacitance based qprox sensor detects the proximity of your hand to act as a switch.
The switch is multimodal; a quick touch cycles the lighting modes to on/dim/off, holding your hand there for 3 seconds enables the speed setting mode - the dial increments one level on the panel meter per 2 seconds held, ie, hold your hand there for 10 seconds and the dials take about 30 mins to cycle, hold it there for 1 second and the dial will cycle at once every 2 seconds.
All control is done with a PIC microcontroller (before I swapped to AVR). This was my first electronics project.
Sound card NeoGS appropriate for playing trackers (MOD) and compressed (MP3) music on Spectrum-compatible computers with ZXBUS slot.

In 1984 Sinclair launched the ZX Spectrum+. A fully suitable name, because the 'Plus' was nothing more then a face lifted normal ZX Spectrum, the big bang for Sinclair that was launched two years before.
The Spectrum+ tried to solve the biggest minus of all Sinclair computers so far: the awkward keyboard.

Not much to look at - but this was the very first computer game that had me pulling an all night gaming session!
I thought my poor old ZX Spectrum was going to burst into flames.
Desert Rats was a turn based war game in what I suppose you would call the board game tradition. The 'tiles' are army units which you must move about one square at a time.
This screen shot show a particularly exciting moment (LMAO) where the German mobile infantry regiment is being engaged by British anti-tank guns!
Looking back on it now I can hardly believe that this minimalist game consumed so much of my time...
Incidentally, I discovered an amazing online ZX Spectrum emulator on which you can actually play these old Spectrum games, go to: www.zxspectrum.net/
The Spectrum launched a generation of UK computer experts. Read about the history, specification and games.
ZX Piano for iPad is a great toy.
You can play the wonderful ZX Spectrum as an 8 bit piano!!!
Just let me know if you want me to send you a promocode!
An arrangement of ZX Spectrum related objects including cassettes, manuals, and joysticks.
Still works! This was the first game console, computer even, I ever owned. The Sinclair ZX Spectrum+ was released in 1984 before I was born. I was given this in first school, probably around 1992. Ghostbusters was clearly my favourite game.

From Christmas list to scrap heap......the hard life of technology - I was 11, it was fresh out the box - I plugged it in and couldn't understand why it could not tell me my name like the ones on TV like on Blake 7 and HAL ......eventually the computers caught up!........yep hours spent typing in BASIC from magazines just to make the screen flash different colours was a hard lesson.
