buildzoid Posted March 16, 2016 Share Posted March 16, 2016 I had an idea for a device that I want to make because I'm sick of having to pick up piles and piles of pots to get voltage control on different GPUs. I guess it's going to basically be a dumb EVC. Basically it's going to be a pile of digital potentiometers with some inbuilt sensing and safeties to make hard modding easier. Here's my goal for the features: 3 channels(VCC,VMEM,misc voltage rail) offering resistances from 2ohms(the lowest I've seen) up to 500kohm(the highest I've seen) Each channel will also have an option to monitor voltage and set limits on how much overvoltage is possible(my biggest fear with hard mods is setting the pots to really low resistances by accident). With some clever coding this could be setup to also counter act voltage drop in situations like the E-power on a TITAN-X because you just tell the device to hold X voltage and when the voltage drops bellow that it will adjust the pots to push more voltage(this might not be fast enough to work properly but you could try to slow down the voltage drop with extra caps to the point where this thing does keep up) Connector so that you only need to attach a connector to the GPU you plan to mod and whenever you want to use the device on another GPU you can just unplug it and solder a new connector to the new GPU. I'm not yet sure what I'll use as the brains for this monstrosity since I've done exactly 0 stuff with any kinds of micro controllers so if anyone has suggestions that would be great. If you have any other suggestions for cool simple to implement functions I'd love to hear them. Quote Link to comment Share on other sites More sharing options...
