    Trying to identify/locate ICs

    That one's the emitter. The sensor () is below.

    Trying to identify/locate ICs

    Hmmm, I sifted through those addresses, and came across a link to http://www.mikesusan.com/lasertag.html, which may be what I'm looking for. It's compact, doesn't necessarily have to work with commercial sets, and I can run it off a 9V battery. The emitter is pretty straightforward (), as is...

    Trying to identify/locate ICs

    Tried, but no response yet. I've found several email addresses for Mr. Bodger, but some of them are bouncing back. I might not have hit a "live" account yet. -G-

    increment/decrement counter

    Hmmm... The bar displays look interesting, but I think would be difficult to run off a battery. I spent the weekend looking over the shift register information, and think that the best solution would be a bidirectional 8-bit shift register, with some sort sort of limiter that when all 8 LEDs...

    Trying to identify/locate ICs

    :) Actually, that's where I got the part #. I'm trying to put together a tag gun for my physics class as a "learn how to do machining" course. However, I couldn't find the parts in Newark, hence my search here. -G-

    increment/decrement counter

    Thanks for the leads. I looked them over, and the first one is for a numeric display, which is too tech-y for what we want. The second looks to be a binary counter, which is also not quite there. The last knight-rider diagram is really cool, and I may build one for another project, but also...

    Trying to identify/locate ICs

    I'm trying to cobble together various circuits into a coherent whole from what I'm finding online, and was hoping I could get some help locating or identifying alternates for the following IR3T07 (IR Preamp) MP1826 (microcontroller) UM3562 (sound generator, maybe??) Thanks! -G-

    increment/decrement counter

    Greetings, I'm trying to put together a project for some students, and it's a bit out of my field. The portion that's stumping me right now is to get a counter that also backslides. The output is 8 LEDs. Everytime we receive a pulse, the number of lit LEDs should increase by 1. However...
