In theory I don't see why not, though the bother may not be worth it.<p>For the 12/16 series they are serial programmed and Microchip have published the algorithm and timing procedures required on their website.<p>Now the big problem is getting the info out of your device to the pic. If you have a t...

Well you have now cos I say so.<p>OR<p>Well I sort of had two trains of thought going and at my age that is just begging for disaster. I had written deflection coils realised my mind was not on the job and only half changed my twittering.<p>Look I just spent two days trying to work out why a program...

Transformers are rated in VA rather than Watts because technically Watts are the result into a resistance of Volts and Current mainly Direct Current.<p>Alternating Current on the other hand (Left or Right theory :D ), has the added fact that the current and voltage are not in phase with each other a...

TV Line Output (LOPT) coils run at 15-25KV -it'll be the lump of plastic lurking near the neck of the tube with the big thick lead coming out of it.<p>Microwave transformers are a possibility (Big CAP near so discharge first) <p>You could also make one see the thread on fence/people zappers earlier ...

Don't have a circuit off hand, but this could be easily done with uP (PIC with onboard UART 16F628/876 would do nicely). Receive the data then use an 8 bit port to output to the parallel device.<p>Plain serial to parallel conversion could be done using a shift register such as a 74**595 or similar.<...

An Op-Amp could do this using the inverting input. Or were you thinking of using an ADC chip or uP?<p>bodgy

Aha is that an American mile or an Imp Mile and is a block a recognised ISO or AS or even a BS. :D <p>Now who's going to write the manual for -<p>? Blocks in a Chain ' '' 'Furlong ' '' Rod ' '' Cricket Pitch<p>Mind you I can't remember how many chains to a cricket pitch 22.5 or something - SCHOOL wa...

Being a foreigner I have never quite grasped what distance a block is - so I take it its a mile square?<p>Anyhow cordless telephones - standard 27-30MHz have a guaranteed range between 10-50M approx from the base station (upto 30')has been known to work to 100'. New digital/long distance style upto ...

It is possible the delay is needed to either stop a current surge to the equipment at switch on, and/or, to prevent stress to the transformer and output drivers.<p>

Distel in the UK have new and second hand ones!<p>

Look in this months edition of Elektor Magazine, I believe it's available in the States.<p>They have just this very thing including copybit protection for your OWN personal use.<p>Sorry can't email you a copy unless you want to wait until next March when I receive the CD version of the years issues....

good grief, the last time I saw a double cap was in a valve radio!<p>bodgy

Gary,<p>It depend if you're wearing a smirk as you say it.<p>Your right on both counts - view carefully any Carry-On films assuminmg they made it to America.<p>bodgy<p>PS just in case a smirk is a slighty lascivious grin

You could also try a wheel with a small cam on it, this would provide the same effect, in fact it's how some rotational devices get their eccentricty.<p>
