Yeah, we might should try “replace the USB cable” right after “check that the power is plugged in”! ;-) (Amazing how many “problems” are…
Hey John, Good catch, but sorry, not the one. I totally didn’t even think of heat sinks while designing this, or after using it so many…
Hey Madbodger, Thanks for commenting! What do you mean by strapping? I’m guessing, like a jumper option? If so, that’s an interesting…
Hey jma89, Good guess. Thanks for looking at my design! I can see how it looks that way in the picture. Although there are some slightly…
Hey Haathi, Thanks for commenting! Good eye for sure. But sorry, that isn’t the design flaw I’m looking for. It isn’t an actual assembly…
Hi Pete! Here are a few things I noticed: - The vias aren’t tented. Many of them land in the middle of silkscreen component values, making…
Hey 773, Thanks for sharing! Indeed, it sure is nice to have field-replaceable parts on wear-n-tear testing equipment. We probably replace…
