Hi,
I heard today of an operation which was televised to medical students wearing VR headsets, so that they could 'see' exactly what the surgeon was doing. How's that for a serious use of VR?
But I don't want to see that for my after dinner TV watching.

bought for job purposes, I mean aging non-standard system is just an accident waiting to happen, and one day it's going to fail and your business will be halted while you desperately try to source a replacement. That is the case, I bought it for a customer, and I will probably sell (instead of being paid for the service I am going to offer) once job completed.

Two Arduino shield-compatible dev boards with 1284 surface mount chips through Budvar10.
It's got the same size and headers as an Uno plus another row on the back.

Name on the back is @rduino Pro 1284.

The one that I've checked is 24MHz the other not checked is 16MHz... I want one at regular speed.

I ran the 24MHz with a 6 red leds on 220R's for about 30 mins and the chip didn't get warm to finger touch test. Where loop() ran at 86KHz on an Uno it ran 128KHz on the Budvar board. That IS a kick!

Everything is nice, a professional job and the AVR has a crystal so I expect better timekeeping than the Uno though IIRC there is an option for extra on that front but I forget the details.

The thread I first saw the board on -- the 24MHz got me to jump.

The GitHub page with all the files for all the versions.

Only thing is I needed to add to the boards.txt patch to get the IDE to work, here's what does for me:

I put all the choices in. I may want to try OC stand-alones.

Ah, this is obviously some strange usage of the word 'safe' that I wasn't previously aware of. (D.Adams)

I really pushed the boat out today and got a few dual 7-segment LED displays to play with, never having used one before.

But while I was waiting I was drooling over the Fluke display.
