Re: I am at my wits end..
Well here I am, any constructive feedback is welcome. . One place to start, is to re-read all of your previous posts in this thread. You make a lot of noise about almost everything. Why complain about getting a fake unit here? It's not jye's fault that you got cheated. Why complain about Chinese ne...

Pingpong:
You behave yourself like a kid.
You want a genuine item, but don't want to buy from Jye because they are too expensive. Jye says Banggood is genuine, but you don't trust it.

Re: Measurement errors with x10 probe on large negative sign
I have modified my scope now, and it appears to be functioning OK. I use SENSEL3 for switching the LED on/off. To avoid mixing too much into the existing circuit, I choose to use a separete transistor as a switch for the LED and only use one of the spare switches in U2 to control that transistor. A ...

Re: Measurement errors with x10 probe on large negative sign
Thanks for bringing up this problem. I have done some very rudimentary testing with a home made optocoupler consisting of one 5mm white LED and one GL5549 LDR (cost almost nothing on ebay) since I already had them. Instead of changing the input network as suggested, I just lifted pin 12 on U1D from ...

Re: Li-ion power mod
Some pictures of my implementation inspired by the previous posters. Battery is Motorola BH6X and charger / stepup as shown in my prevous post. The stepup is lifted about 0..5 mm above the PCB to avoid shorts and the charger is held in place by some strong double-sided tape. I have added some foam b...

Re: Li-ion power mod
Hello upsss or anybody else who can answer. Appreciate the description and photos of your implementation. I've ordered the parts, now for a 1 month wait to arrive. I could use some help as to which SMD feedback resistor on the step up converter board needs to be changed and from what value to what ...
