Trying to identify/locate ICs

[GordonSmith]

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!

Manufactures would be helpful. Sharp Toshiba?

IR3To7 is a Preamp.
CLICK HERE TAG GUN pdf
It is not a Datasheet but it is helpful.

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.

Here are some other circuits to look at.

Have you tried Emailing the Author?

[GordonSmith]

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.

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 the sensor (

). A question remains (as I can't seem to find an email address on the author). Do you think I could attach multiple IR Receiver modules to the 567 in the sensor, instead of multiple 567 outputs to the 555 timer?

Also, I think the 161 chip is a 74x161 counter (say, DigiKey part #296-2096-5-ND), but could someone more knowledgable than this humble llama confirm that?

 

[hotwaterwizard2]

I don't see a 161 in this circuit.

 

[GordonSmith]

That one's the emitter. The sensor (

) is below.

I think you may be right. Compare for yourself.
