12:41 <mtrbot-ml> [mattermost] <sb10q> does anyone know a cheap and reliable computer-controllable power supply that can deliver ~40A at a few volts?

12:42 <mtrbot-ml> [mattermost] <sb10q> it doesn't need to be low noise or otherwise fancy, it just needs to deliver those amps, have a firmware that doesn't crash/suck, and not cost a lot

12:44 <mtrbot-ml> [mattermost] <sb10q> I have a Ca oven (DIY construction with a piece of stainless steel pipe across a high-current vacuum feedthrough) and with manual control it is very easy to evaporate too much Ca and make a mess

12:45 <mtrbot-ml> [mattermost] <sb10q> the evap rate increases very quickly with current once evap starts + there's some thermal lag, so control is difficult

12:46 <mtrbot-ml> [mattermost] <sb10q> but in the final system the control software will eventually get a measurement of the evap rate, so I could just servo a programmable PSU
