Hi, the guys and gals on 4hv started one of these.
It made it round many states of the US, before it got lost.
Might be worth keeping the more expensive parts in one location and sending a "mini box" rather than the whole thing, on the basis that it reduces postage charges and is less likely to be lost in the post or nobbled by Customs/etc.
OTOH, if anyone wants to contribute to a UK/Europe box I have many many nearly antique surplus components, a flat CRT, vacuum fluorescent tubes, sensors, small batteries and other goodies here waiting for a purpose.
PM or email me and I'll send a box in your general direction
Kind regards, -A
