I'm mucking around with the cool little AS3935 lightning sensor IC, however being in the middle of winter, storms are a bit hard to come by up here.
AMS sell a dev kit for this chip, which includes a little board that lets you emulate various noise and lightning strikes, however it's $240, and I've already got the IC wired up and running.
From what I can see, it just has a basic uC and a DAC, and some sort of antenna. The chip says it's frequency detection is around 500Khz, so I'm trying to figure out a way of basically copying the operation of that board.
I'm mainly wondering how I can go about creating 500Khz RF pulses that I can control with a uC, anyone got any ideas?
