If you're in the UK I've got some boards based on the ones Jules did that. Just need to sort out the slider plate and build some up. Welcome to have one at cost for test, if you fancy. They should be less than 20 iirc
Great!
I've just been quoted the same price for the alternatives. Hopefully I can get the shipping done to the UK.
I plan to use the following Piezo preamp from the guys at Stompville.
Worked fine for the Geophones that I made and will come out at about half the price of the JLI boards after factoring in postage etc.
Will post back when everything is done.
