Obviously not in the same league as the other version, but if you're
only interested in low frequencies ...<br>

The DS0150 appears to be 200kHz analogue bandwidth which is a bit
restricted.
<br>
<br>
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.
<br>
<br>
May have been based around something like

and 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.
