Finally the time has come. Here I have it wired up for fire test 2.
(Before I finish any DIY-ed product it needs to undergo 3 fire tests that check if the product literally catches fire -
Fire test 1: check for any instantaneous complete or large-scale destruction of product or attached equipment, usually resulting from short-circuit or fast overheating. Ideally carried out with a light-bulb tester, but without it you can be just as fine with proper-rated fuses, secure grounding, and a keen eye for spotting smoke. Test lasts for a few seconds to a few minutes before powering-down to check for problems.
Fire test 2: check for short-term functionality and any other possible major/minor causes of failure. After checking all voltages are correct product is plugged in and turned on fully and more measurements are taken with the product functioning. Things that are checked include voltages of power supply, signal/power/chassis ground, in/out DC offset, and continuity of major conduits/capacitors.
Fire test 3: check for long-term stability of product in worst-case-scenario conditions, also known as stress-test. I decided not to do this one as it is usually related to cooling and power, and this thing has overkill cooling - a relatively big heatsink with fan for the chips that won't put out even 5W of heat under my normal use, and the power supply which won't put out much more than 5W either I have it bolted to the bottom of the chassis which becomes a large heatsink for it, coupled with a generous helping of Analbond. I can expect this thing to blast for hours while maintaining at room temperature.)
The electrical wirings to the connectors on the chassis are not done yet, so lets call this version 0.9. The version number will indicate the performance or feature/functionality/bling upgrades that it has received, v1.0 being stock. I didn't plan for a v0.9 though.
