Have a question?
A really good feature will be current limiting feature and voltage up to 9V, but anyway the hardware is already very good like that.
I used to spend a lot of time in the lab when I was a board design engineer. Now I'm a cryptographic chip design engineer, so I only occasionally go into a lab to try on my designs when the silicon comes back. One of the problems I always encounter is getting hold of useful power supplies. (1) They tend to 'walk away' if left unattended. (2) Modern silicon runs on low voltages (E.G. 0.6 - 1.3v ) and the PSU control ranges tend to very coarse relative to that range.
The idea of having my own USB powered/controlled, voltage and current limit controllable PSU that I can take with me in my laptop back would is very exciting because it would solve all my PSU problems. I don't personally have a need for higher current or voltages, but other people might. I'd pay more for a device with independent current control since it takes an extra knob and display. Being able to control it through USB and script a bringup sequence that ramps the current until the right voltage is reached (or abort if it takes too much) would be awesome since it would be more accurate that turning the knob with my fingers.
Hi James and David!
We have discussed your suggestions and have to agree. As this is the first iteration we clearly have room to improve. At the same time, portability and cost effectiveness are key ingredients. We have started working out how to incorporate current control without adding significant costs to the build. We have also been looking at alternative housings in order to increase the portability. So James, we're going after those extra points you mentioned.
Thanks for the feedback,
Brad and Mike
I agree with the other guy. Think about independent control and display of current and voltage. This is what distinguishes a useful lab bench power supply from a useless lab bench power supply.
Looks great guys! Killer features I'd like:
- As thin as possible (pocketable)?
- If not thin, tiny alligator clips and leads stored within device?
- Press a button to change to Current Control (extra points for independent selection of current and voltage display and current and voltage control)
But if it was just as it is, you have my money! ;)
