Preamble
Need to get some PCBs made, preferably from Eagle .brd files, but not everyone accepts them and they want PDFs instead.

LED strips from fluorescent tubing
Preamble
I was given a number of LED strips from flourescent tubes the other day. After a quick look, I noticed that the 36 LEDs were grouped in bunches of 12. I went an got a 12 V 2 A LED power supply, but only some of the LEDs flashed. So, more investigation was required…
Wilson II print times
Preamble
Following on from Building a Wilson II in Bangkok and the somewhat crazy prices for locally sourced printed parts, after finding out that a neighbour has a 3D printer, I decided to have another attempt at printing the parts for the Wilson 2.
If print time is charged at 1 baht/minute then how much would it cost to print a Wilson II 3D printer? Or more precisely, how long would it take to print all of the required parts?
Perspex in Bangkok
Preamble
I needed some perspex, or plexiglass, in Bangkok, but didn’t know where to find it cheaply… so yet another voyage of discovery.
Coin Operated Brain
Preamble
Following on from Reverse engineering the coin box, the microcontroller used is the MC68HC908JL3 DIL-28, or a similar derivative.
Capacitors for Sleeping iMac
Preamble
Following on from Sleepy iMac, here are some capacitors that might be a good fit.
Reverse engineering the coin box
Preamble
Tenuously following on from Laundry in Thailand, the coin operating box often suffers problems, namely the coin slot and the control PCB. The former suffers from failure to register a coin. The latter sometimes fails to start the washing machine.
