Ha that's a cool little gadget, unfortunately I don't know of a similar charging chip. I took a look and the stuff on there is pretty cheap though!

Hi!
I want to work on an offline power supply (flyback) 50W (100W maximum) prototype from 230V 50Hz and I want to be able to check signals with a Rigol DSO, and obviously, work safely.
What would be the professional approach?
I'd like to buy an isolation transformer but I don't know which one would satisfy my needs, nor where to buy one from Europe.

I'm not sure about the exact approach but I do know that some have gotten the parts from ebay.

Bus Pirate Support / Re: Bus Pirate Firmware 6.3 BETA development

May 29, 2013, 09:31:36 pm

This update also seems to increase the stability of the SUMP / logic analyzer mode. With the 6.1 firmware, I frequently got the bus pirate to lock up at the end of a capture (it stopped responding after two of the five reset commands sent by OLS), when using smaller sample rates (e.g, 4Mhz was ok, while 20Khz would break nearly every time). I haven't been able to reproduce this since upgrading to 6.3 beta1.

I had a bug with the previous firmware but so far the update is MUCH more stable than before. I'll keep monitoring for improvements.

Thanks for letting us know. I had a look on ebay for some parts but didn't really find anything, are the supplies good quality?
