Yeah, I'm leaning that way. Unless I can find a stash of Windows XP laptops before July! :)

Good to hear, I also remain an old school PE5 user. Old habits die hard. But I'm teaching some Picaxe summer classes and wondering if I should be teaching PE6 to first timers. Decisions, decisions!

IWP=inglewoodpete, a well-known legend in these parts. :)

IWP FTW!

Or just grab a 1980s-era 9400 V-F/F-V converter chip! https://www.farnell.com/datasheets/32473.pdf I love my old Radio Shack books by Forrest Mims.

Ah, target shooting! I like it! Definitely house the transmitting LED in a flat black tube with a lens to collimate the beam. In doing so, you concentrate the IR energy and you can probably reduce its electrical power output to reduce bleed over.

It's not clear what you are after. What's your goal? Are you making a fixed-position device? Is max range a consideration? You chose 56 khz to avoid interference from 38 khz devices? Pinholes are reducers, lenses are amplifiers. Strong IR reflects off walls and ceilings. Lots of experimenting...

The all-girl students team made a pink 3D printed case and I put the guts inside, the unit works great. Picaxe FTW!

I may be interested. I did the electronics in the prototype of O3's ozone garment sanitizer during Covid. Pretty cool freelance project. Garment Sanitization | O3 Technologies Inc

Lenses on both ends can dramatically enhance reception.

I suggest you take a stab at it. No matter what your age, Picaxe is about the easiest micro to use and likewise for Picaxe Basic. TTYTT you need to understand Picaxe Basic and all its features to get the best use of your Picaxe hardware. I don't suppose you live near Los Angeles, I will be doing...

Russia is littered with old RTGs.

THANK YOU ALLYCAT! You saved my bacon tonight. I was just contacted by a panicked high school advisor yesterday. A team of graduating students was left high & dry by some sketchy tech company that directed them buy a bunch of Arduino hardware to run a color sensor. The students have been working...

I bought a few Windows 10 license keys for $3 from https://keyvoo.com/ , which were legit and activated just fine. They also sell cheap Office License keys. I guess they recycle the licenses from e-waste computers.
