Recipe:
1. Take one broken Orla DMK8 midi keyboard from your mate in Paris.
2. Realise you'll never fix it (realisation pre AAC membership) so pick up hacksaw and cut out power supply section.
3. Bravely and cluelessly solder 5v regulator to seemingly free posts. I figured the designer wouldn't have installed it hovering over the board, there were three pins doing nothing and amazingly after bothering to apply more brain power and check the pin out found I was correct! (I try and approach these type of issues in reverse now and check first)
4. Pull interesting steel stair tread from hedge, take home, hack to size and pop rivet on. Save the rest for other projects.
5. Using as many original screws, wooden side cheeks etc from the Orla assemble into useable box; spray then smudge paint through impatience.
6. Try to make as Gucci as possible even though you have no real idea what you need. Install neon mains indicator, Led's to indicate +12v(Red),-12v(Blue) and 5v(Green). Learn that the 5v is for the Logic chips and assume (as I type) negative supply is for op amps.
7.Mount switchable 3.5mm and 1/4" I/O on rear panel and breadboard. Mount speaker terminals for the hell of it as well as second switch and 1/4" jack (not yet wired- I had a spare hole after no planning). I have taken a small speaker (1/4W 8Ω) from a kids toy mic and mounted it via magnetism. They seemed drawn together....groan.
8.Start building Analog kids Tabata Timer despite lacking CD4060 because of impatience.
9.Repair Banana connections to breadboard. Get frustrated because manufacturer has coated the pins but persevere and win through eventually.
10. Install adjustable rubber feet taken from below school desks (retired) and save £5 at Map@~n.
11. Wait for post man to arrive.
Please comment with any ideas to add to this-I don't know what circuits I will be building in the future (cat scarer bumped high on list) but am already thinking LED meter or V and A meters (range req.?). I will post a hand drawn (my first) schematic and a question about the different sized caps on + - 12v circuit a bit later. My guess is they differ due to current requirements....
p.s. yes I broke the 5v regulator and just tacked it back on for now. Ugly but working. (at least the LED lights which is my only proof...Logic may be some way off for me yet.) Soldering is still a challenge.
