Wikipedia states that Hermes is the god of commerce, as well as trickery and thieves (amongst other things). The latter two might be best to describe Hermes – the courier company. In fact Perses would be a more suitable name for the company, as he is the god of destruction.
I had purchased an absolutely beautiful Fluke PM3092 oscilloscope, and was really looking forward to receiving it. When it arrived, in fact before it arrived, before I had even opened the door I heard the delivery guy drop the package on the floor. “That doesn’t sound good”, I thought to myself.

A follow on, bulk move, from Pocket ‘scope to deal with bench DSO is its own separate blog, rather than a small section in a blog about pocket oscilloscopes.
I had always been after a DS1052e/DS1054z, due to Dave’s EEVBlog videos, but after reading Owon SDS7102 vs Rigol DS1102E vs Rigol DS1052E Review, I realised that the Owon has more features (VGA, LAN and battery operation) as well as a better screen.

A colleague and I have been trying to reverse engineer a few different PCBs recently (a coin operated washing machine’s control board (see Reverse engineering the coin box) and a Bastl Trinity are a few examples) and we have been scanning them or simply photographing them, with the aim of either copying them, coming up with a schematic or coming up with a PCB mask, with mixed or limited results. Like this:
After watching EEVblog #675 – How To Reverse Engineer A Rigol DS1054Z, I saw that Dave explains a pretty good process, using a tripod mounted camera, light box and a back light.

Leading on from Miniscope, I wondered if I should/could improve on the front end of the STM32F103C8T6 board based scope which connects to

Following on from Pocket ‘scope, the section on the Miniscope became too large and so was moved to here.

Following on from Pocket ‘scope, the JYE Tech DSO150 (along with the DSO138 mini) seemed the cheapest and best (for the money) option.
I also came across a number of different hardware and software hacks, which I have assembled below.
