    Picaxe touch sensor for ham CW keyer?

    Has anyone made a plain (non-touch) CW keyer? Would be a great 08M2 project. I'm old-school, some 40 years ago I built a multi-IC keyer kit which I got from a hamfest, based on WB4VVF's 1973 Accu-Keyer, which worked great. Nice options including auto-space, etc. Funny that an 8-pin Picaxe could...

    Kolobot with 08M2 and H-bridge

    Nice project. Lately I've been using these MX1508 dual H-bridges: https://www.ebay.com/itm/292947397109. At 78 cents for TWO prebuilt 1.5A motor controllers, it's just not worth building H-bridges from discrete components anymore. Same 2-pin control (per motor) as described above, with both...

    14M2 Trade Show Prop

    For the first time, I can call a project "finished"! This was a prop for New York Toy Fair Feb 16-19 2019. It was a freelance job to create a sort of slot-machine game to promote a small new plush toy line called "Foodie Roos". The spinning eyes had to index, so I used some new servos from...

    Development board that plugs directly into USB port

    No, just whoever's cheapest. Pic attached of the ones I made to use in my classes. I prefer this white-screened PCB with the diagonal SMT IC since its output pins mostly line up with the 74HC14N inverter pins and require the least soldering. Simple enough to fabricate on a scrap of perfboard...

    Development board that plugs directly into USB port

    There Windows has always worked fine for the 20+ CP2102 adapters I have made. There was a driver conflict after the 1803 update last year, but SiLabs fixed it. Back to working great now. https://www.silabs.com/community/interface/forum.topic.html/cp210x_driver_v101-91Gl

    Development board that plugs directly into USB port

    Why wait? Just make your own cable as Goeytex showed with a dollar CP2102 usb dongle and inverter. You have 5V and ground pins right there.

    PE5 No Sound

    There are system sounds in every computer except this one. Looked at sound manager, settings are all set to default. <scratches head>

    PE5 No Sound

    A student is running PE5 on his computer. It works fine, but there is no sound from PE5 when verifying or downloading. Other sounds on the computer work fine. Is there a volume control or toggle somewhere in PE5?

    Development board that plugs directly into USB port

    That's incredible... there's a Chinese Ebay seller offering ATTINY85 boards for USD$1.50! There's another cheap ATTINY dev board with USB adapter and 8-pin DIP socket. An 08M2 sure would look great plugged in there, but it wouldn't do too much. Mod Edited (hippy) : There's no problem in...

    setting up a new windows 7 computer to use the Editor

    Hey Gramps! erco here from Parallax too. You should be fine swapping your cables back & forth. I've set up 9 laptops for programming school. With fresh Windows 10 installation, every computer defaults to com 3. We mix & match cables, computers and physical ports and everything keeps working...

    Other options to wirelessly program PICAXE?

    Big and clunky but this guy found a wireless USB hub that programmed a BASIC Stamp in 2011, an IOgear GUWH104KIT . I haven't tried it myself, but I know that in general, adapters that work with the Stamp also work with Picaxe...

    I feel like a fraud!

    Un. Bee. Lee. Va. Bull. WOW, incredible! At first I thought it was a motion control flight sim on hydraulics, but it's a kid's bed? EVEN BETTER! WOW! Any kid (or adult) would love that. Could never sleep, but who cares! Are you surprising your son with that for Christmas? Does he never look in...

    Inductive charging of a Lipo

    If you want another long-term experimental project, spin that magnet. It may be possible but there is likely a reason no one else does it that way. Moving parts wearing out, noise, etc. If you want a quick solution, go with Sparkfun.

    Picaxe Class

    I taught my second class in programming 08M2s last night at Bit Torrance (my new school at my new office). It was National Computer Science Education Week, and it helped that we rolled happy hour into it. From my experience, bits & beers go together well (PICs & pints?)... our "Happy Hour of...

    Most excellent work, hippy! How nice that late_voyager, a new member, discovered a singularity in the fabric of space-time.

    hell.p 20m2 pin c.7

    He wants C.7 as input. @ LATE_VOYAGER: Just for sport,, try INPUT C.7 after CALIBADC.

    hell.p 20m2 pin c.7

    Hmmm. Not sure about this one. Unlike C.4 and C.5, pin C.7 has ADC capability, possibly related. Is it an option for you to use input-only C.6 instead of C.7, or have you made a million of these PCBs already?
