If you don't mind a bit of coding, then could always buy the OLED graphics LCD and write the access code. Have a look at Conrad Electronics (don't bother looking for America as a country they don't list it but Venezuela and Zimbabwe go figure!) Anyhow they have some starting at 30Euro going up to 14...

I recently received the Heat Management DVD from Optek (the LED people). Ignoring all the sale pitch stuff they ahd some interesting things to say about LEDs. 1. They are only 8% efficient once the heat and photonic losses are taken into account. This refers to high power white LED's 2. The most int...

Realising that it says COAG and not COAX, perhaps it is a cauterising device?

A capacitor with an indifferent plate - I like it! :grin: Anyhow, I don't see it saying what type of triode is being used or what the voltage off the transformer is. Theoretically you could replace the valve with a J-FET or maybe a dualgate MOSFET assuming the voltage off the transformer is in line ...

Just to add in -Hitech are now offering their 8 and 16 bit Pic C compilers in a 'lite' edition, free download, but has optimisation switched off unless you pay big bucks (U$1100 approx) for the full professional version. Reports on the Piclist are that with no optimisation it creates horrendous asse...

Aah the terminolgy difference between English speaking languages, what is a baseboard heater? Is it an outlet that is piped under the floor and vents out in the skirting board, or more like a free standing radiator style? As I typed that I just realised that certainly in Queensland, Australian homes...

I think this is a genuine request for help with a part identification, the website is a Serbian broadband/cable company, and this poster has also posted to the CNC Forum for the machinist community.

USB Flash drive recognition

I've just discovered that some flash drives don't report themselves as mass storage devices but as hubs. This seems to be a bigger problem for Linux users, but if you have a USB stick that works on some systems but not others, or a USB drive (powered type), then this might be the reason. I found thi...

Al, I must be having an off day , Since the wire size is 1/10 the secondary size, that makes its resistance 10 times less than the secondary The smaller the cross section the higher the resistance. R = ( length of wire / cross sectional area ) * resistivity per metre of wire used. Assuming an Ï

It is possible to use the triangle idea for those parameters that use time as part of the equation, though there is one extra step. so for capacitors. i would be on the top 1/3 of the triangle. below it would be c | v . Like this of course t is missing so that needs to be placed next to the i So - i...
