Spent a few hours building this Banggood (jyetech.com) oscilloscope kit, but the display failed after just a couple of minutes of use. Also, the negative analogue voltage isn't working because there's no pulse train coming out of the CPU. Otherwise the CPU appears to be working fine. All a bit of a mystery.

More Chinese Goodies.
Update - the "Touch Me" LED was quite easily fixed by re-making some of the solder joints.

A quick look at two ADC types - flash ADCs and successive approximation ADCs. Here I briefly explain how both types work and why the latter type (the type used in Arduino) is so much slower.

A bit of a steal from the pound shop - a transmitter and receiver set operating on the FM 88 - 108MHz frequency band. Once I get it up and running, I put my OWON 60MHz oscilloscope on it and look at some signals.
