[cartufer] sent in this sweet little Polonium detector. It’s fundamentally similar to the Geiger counter the other day, but the circuit is simpler by several orders of magnitude. No exotic parts for this one, just some basic metal working skills. (This might be handy when I visit my in-laws.) The page is loaded with several ion detection designs, from simple to very complex.
