[chbot] DS0150, and ilk

[Mark Atherton]

Thanks Volker.

The DS0150 appears to be 200kHz analogue bandwidth which is a bit 
restricted.

Having said that, for US$20 landed, you get an STM32F103C8 CPU and a 
touch-screen 2.4-inch colour TFT display; this seems extraordinary 
value-for-money.

May have been based around something like 
https://hackaday.io/project/20821-multiscope -- not too sure whether to 
rejoice of to cry when someone builds a product into a model car...

want some circuit mods. The DSO wants an 78L05-stabilised ADC ref input 
(currently just a supply voltage resistor divider...). The same article 
said the DSO150 was overall better than the DSO138. Supposedly they're 
supplied with schematic.
