There was a classic instance here in Australia in either ETI, EA or Si C.

The magazine sold for $0.75, and promised to save over $1000, and sold on
ePay for $662.33, so the buyer is still ahead by (+$1000.00 -$0.75 -$662.33 =
$336.92). What a deal!

I like Nuts and Volts, but I like the good ole Radio Electronics and Popular
Electronics (both USA), Practical Electronics ETI (UK) better. Elector
Elektronics (NL) is OK but many projects of today are PIC-based.
Aussie Silicon Chip is OK but a bit expensive.

Thanks for that comprehensive answer Jeff.
I think the risks are too high (for me) to produce anything using
these cells atm although I'm sure they will vastly improve over time,
they've come such along way already I know how they have made electric
powered aircraft so feasible with power and
I got 7 or 8 helis.
I now fancy a turbine powered as well.
I don't mind spending $1000 on a heli, but $8000 is a little to much for
me.

Hi all,
I have been away from this group for a while due to travel etc but now
I'm back with a link to a video of my latest clock. It's a 6 digit GPS
locked E1T clock with a nixie tube to show the number of satellites
being received. It's very cool even if I say so myself. Take a look
at:
How about the current it draws when setting the time? This might take
like 30 seconds or more to complete.
You could use a parallel supercap if the 3C currents only last for a
split second.

Yes, I like optimism :). Most of the things I design *must* be
finished in a few months, so that includes the watch, although there
isn't really any pressure on that one. If it takes too long, it will
just end up in a drawer where I might find it again after 5 years or
so.

Hi Morris,
Been awhile since you chimed in. Nice use of E1T tubes.

From what I've read, its count direction is due to

Can't fire one up, if I can't get one. None on eBay, nor the Russian
