Hey I'm reading 23kΩ resistance on the test points labelled GND and 5V (and 3V.) Is that bad (as in don't try to power it up)?
<lukego>
(Maybe I'm being impatient and the board hasn't tried properly since I gave it a wash...)
<d1b2>
<Attie> depending on polarity, i see ~15k / ~30kOhm
<d1b2>
<Attie> don't forget that there is an amount of capacitance on that rail, so you'll need to wait for the reading to stabilise (it'll likely start low and rise)
<lukego>
thanks for checking! close enough for me
<d1b2>
<Attie> have you turned it on yet?
<lukego>
nope but ask me again in thirty seconds :)
<d1b2>
<Attie> now test the bottom left pin of U15 (as oriented in that photo) - should be 5v too
<d1b2>
<Attie> (that's an enable pin)
<d1b2>
<Attie> also worth jusy checking for dry joints, etc... (reflow / add a bit of solder)
<lukego>
Right. I committed a LOT of soldering sins while hand-assembling this board one part at a time, definitely e.g. put a LOT of heat into the FPGA and FX2 and that area of the PCB, so I should give the disclaimer that there's a high risk of spending time chasing soldering bugs
<lukego>
(and I'm happy to spend MY time that way but shouldn't take it for granted that others do too :-))
<lukego>
yeah 5V between ground input and bottom-left pin of U15
<lukego>
Maybe I'll call it a day now and in the morning I'll make another pass over the PCB looking for soldering faults, adding some solder anywhere that looks iffy
<lukego>
Thanks for this help! I am using this Glasgow as an entry-point into learning soldering and electronics so it's a bit of a slow process

lukego: now that there was no smoke with the current limited bench supply - did you try to plug in the usb? that would be the next thing I'd do once there is no smoke with the bench supply at 5V
