It looks like a standard HD44780 display, 16x2 character with LED backlight, the pinout seems to be identical (first datasheet). 99% of character...
heh, I did actually think of something similar to that using a voltage divider which the transistor bypasses, it seems NPNs dont like being before...
hmm, this doesnt actually work... I have spent a good while trying to saturate a NPN transistor with 5v through a variety of base resistors, With...
I am majourly impressed that this thread is still going strong after like 3 or 4 years! I still have the desire to make a giant incandescent clock...
your a star, I tried a similar thing but not with a 2n2222, but i have a stash of those.... I am going to use a similar thing to achieve the 8...
Hi people, I am trying to connect a 9x 7 segement VFD display (from a pole display / cash register) to a PIC uC, using a 4017 decade counter...

quality, i will solder up a splitter tomorrow n try it out ^_^. just hope a magnetic card reader, keyboard and barcode reader can all run off one...
how long a momentary?
i use circad all the way as i like to be in full control of what i am doing and circad allows you to almost "paint" the board but other software...
bahh to late i have done them now.... that would of probably of been a bit too big as i am working now mainly on offcuts...
where abouts are you and what is the size as i will most likely be etching soon.... been a while though and it usually goes wrong randomly but...
only the top three pics work on teh HTML but if you go to index: http://www.malkjos.com/index_files/ pics 10 onwards are what u want......
1st and 3rd lines black, 2nd and third lines blank i think.... its been a while!
i have a full pic programming suite myself personally, thanks though! The problem is not physically doing it it is knowing how to do it, sofar i...
if you have any idea on how to use a PIC to do this or link to information about doing it that would be great, but as for designing a controller...
the keyboard should not send any data unless you type at the same time, which would be silly ^_^. but i will give it a shot somewhen...
i am trying to think of what damage splicing the power, ground, clock and data lines could do... apart from the kboard being low n scanner being...
hmm, i ideally want to keep this as a ps2 based system, as far as i can see it should be possible to simple daisy chain them together... just...
Hi, i have just bought a barcode scanning system as part of my computing project for college, but it is ps2 and does not have a follow through...
