WARNING: MAINS VOLTAGE CAN KILL YOU. COPY THIS AT YOUR OWN RISK. How to build the slipstream box. This controls two laterally-placed fans to create simulated slipstream effects according to the position of the turn co-ordinator balance ball. 17-09-10 NOTE: I DO NOT RECOMMEND the transformers I listed at the end of the video. I've had three now, and they have all died abruptly. I hope it's just because I'm running them close to or beyond their load limits, not because of some problem with my design. I have two Maplin transformers now, rated at 120v/230v and 100W. They are also five times the cost of the cheap ones. If either of these dies I will have to rethink my design. 18-09-10. Having done some empirical measurements, I have discovered two important things: (1) The fan controllers put out around 150v when the DACs are fully open (nominally 5v DC), which is significantly more than the 110v the original transformers were rated for. This means I need to limit the values I set the DAC to in order to limit the output to 120v or less (which is what the current transformers are rated for). Experiments show that a maximum value of 226 (it's an unsigned 8-bit value) is suitable for both channels with either fan plugged in. (2) The fan controllers output 240v when the output carries no load (ie. is open circuit). This is also true when I connect a transformer to the output but the transformer's output (secondary) circuit is unloaded (open circuit). This means that having the ...
