There are many high voltage differential probe on the market, most of them pretty expensive. If you want to have a good product very cost effective, with an impressive performance cost ratio, Micsig could have one you’re looking for. We’ve tested DP10007, a probe useful for differential measurements up to 700V, with 100MHz bandwidth, with a selectable attenuation of 10X and 100X (gain accuracy is ±2%). DP 100007 is USB powered therefore it is possible to use USB port on your DSO to supply power to it. Micsig sells their probes with a plastic carrying case and all the well made measurement tools you could require during its use.

Nowadays almost every electronic gadgets are powered or recharged by a USB port (full size, mini o micro) as well as many of consumer products we use every day, including our smartphone. To recharge or give power to such products, there are many portable rechargers which have a rechargeable lithium battery and the electronics necessary to convert the battery voltage to 5V and to recharge the internal cell. The cost of these smart chargers is very affordable but we’re hardware makers, aren’t we? So why don’t to do it by ourselves to give power to our Raspberry Pi, arduino or Beaglebone black? We’ll show you a possible way to design one of these intelligent portable power supply.
