Fortuneatly they don't cost quite that much anymore. https://www.haascnc.com/we_spec1.asp?id=MINIMILL&sizeID=8_20INCH_VMC#gsc.tab=0 this one only costs $34k and could make these parts. Of course, you will have to add a few thousand in tooling to that, and a $8000 a seat CAM package if you want...

Only about $40 (and my lunch breaks for a week and a half), but almost all of the material came out of the scrap bin and I designed around what I had on hand. I bought the microcontroller for $16 , 3 sensors at $5ish each, and the magnets, which were like $.30 each but the shipping is...

Sorry for the fuzzyness in the pic, my wife wasn't here to help me, and aluminum is very reflective. I have been working on these for the last 2 weeks, finished programming the microcontroller today and have it working as a USB HID in windows. Mostly aluminum construction with a few bits of...

That was awesome! Its like a Star wars version of Heavy Metal.

They are using the opamp as a unity gain current amplifier or as a buffer. That's useful when you can get the voltage you want from your microcontroller, but need more current, or you need to change the impedance. Most 'duinos output have a pretty high source current spec though, so i suspect...

I did a little digging. The Arduino Nano seems to lack the ability to be used as a USB HID. In case you are unfamiliar, this is a USB Human Interface Device, a generic term used for a keyboard, mouse, joystick, or thumbstick. The Nano uses an ATmega328 or ATmega168 chip, while the Sparkfun Pro...

Nice! Don't forget to put a TEST logo on it

You should check out Teensy. https://www.pjrc.com/store/teensy.html Default support as a USB HID and arduino compatible. The Teensy 2.0 is powered off the USB port and runs at 5v, so its probably better than the 3.0 and 3.1, which are limited to 3.3v. Works with MMjoy also.

Do you have the internal pull downs enabled? Are you using them for something else?

Yes

Great work! You turned that around pretty fast.

I'm pretty intermittent during the week, but Saturday and Sunday are good for me. I do suck pretty bad at racing, but if you can't win, crash into the guy who can! Probably after 6:00-9:00pm ish during the week, When ever I wake up (10 am-ish) to sometime later on the weekend. Az time UTC -7...

My usual beer is Pacifico, pretty similar to Negro Modelo, maybe a tad lighter. Otherwise i go for a G&T, or whatever my wife puts in the fridge/cupboard

Aurora LN and a 315p

Hi all, checking in, When looking for an org, I'm pretty sure you had me at Friday night drunk squad. I do what I can to make BEST squardron bester
