Re: 48V issues

A good point. I'll get that supply and I'll start working through the notes you had. Thanks

Re: 48V issues

It's a pretty small propeller chip (gadget Gangsters prop module) so about 1.5A. The 12V was for the 1-wire devices but my son just pointed out that I can run all the ones on the boat with 5V. So if I get 1.5amps at 5V at the input supply, I should be golden. The chip runs at 3.3 but the 1-wires use...

48V issues

I thought I had seen an answer to this question before, so if someone has the link, please send. We finally got our electric outboard boat working. Four 12v batteries in series with an AXE controller. We have the speed we hoped and so far, all is good. Time for the next step. Power Gauge; We need to...

Re: Peltier Project

Interesting ideas all.

I guess you all have convinced me that it is just not worth doing, or at least not the way I wanted to do it. I'll do a bit more research, but the one pie per case idea sounded interesting.

Thank you all for input. I appreciate the thought you all put into this.

My plan was to put a few peltier junctions across the top, cold side heat sinked to the inside of the box, hot side heat sinked to the room. Usu...

Simple Midi External Display

Boy I wish. I tried that. The issue is that getting the metronome and the Midi-piano in sync is a bit rough. If both players were human, this would have been a non issue. I've tried kicking both off at the same time. Any delay is the computer causes me a an out of sync. Still looking for suggestions...

Simple Midi External Display

I would like to find a simple way to trigger an LED based on a midi channel. We are using a midi piano to accompany my son. In a few sections, the backup stops, and it is quiet while he keeps playing. Then, it resumes. Our problem is that his sense of time is not developed enough to rely on him gett...
