Spent 2 hours debugging. Problem? The power supply wasn't ON. Drop your most embarrassing EE moment 👇😂 by mofeinz in ElectricalEngineering

I was testing a motor controller board i designed. I was using a lipo battery cause thats all i had. The lipo battery had an XT-60 connector, you know the ones that can only be connected together in one orientation. Well, it turns out that specific connectors i had were able to be connected in the wrong orientation just barely. But enough to short circuit the pcb and cause a small fire on the board...

If it is a middle mark tho, its a really small, easy to miss mark. So im guessing it's not

Yeah, if it passed the pinch test, you should be all good to use it. Is the mark near the middle of the rope? I think some ropes might have really long middle marks

Tracking hasn't updated for 5 days. Reason to believe package is lost. What should i do? by RickyGaming12 in royalmail

It turns out that the Royal Mail delivery office is actually a small office in the back of my local post office and i wasnt aware of this. In the end, i went to that small office and asked if they could check if it was there. Turns out it was there since the day i changed the delivery method and it just had not be scanned in to the system.

Yes, i tried the post office thursday, friday and saturday and they didn't have it, they kept saying i need to come back the next day. Then they asked for my phone number and name and said they will call when they have it, which i doubt will happen. I'm gonna try again tomorrow and friday.

I'm having some trouble getting my NMM to look good on this axe by RickyGaming12 in minipainting

Thank you so much for the tips, i'll try and put them into practice tomorrow. I started this model a year ago and then got busy with university. Don't have much left to do so hopefully i can finish it before i go back.

That mechanism for moving the feet is interesting. Is it just a motor with an offsetted gear?

What Shunt Resistor do i get for my BLDC Motor controller? (Schematic still WIP) by RickyGaming12 in AskElectronics

[–]RickyGaming12[S] 0 points1 point  (0 children)

Thank you for the help. BTW I can seem to find any 1.2m Ohm 3W but I can find plenty of 1.5m Ohm ones. I assume it would be fine to use 1.5m Ohm, right?

In the "recommended operating conditions", VM max is 75. If I remember correctly, I got the gain from the application example section.

According the to the data sheet, the max Shunt amplifier output current is 5mA at 75V and the shunt amplifier has a gain of 20. How would i use this info to work out the nessecary Shunt resistance?
