Re: Robot arm - free for postage

Homer Simpson better watch out, his job pressing buttons at the nuclear power plant may be at risk! I think he is still quite safe! :lol: If the Break key does nothing until you release it, then can't you add a "raise the arm" instruction to the program, making sure you've allowed enough time for t...

Well in part at least. Not sure I'm prepared to fit link 5 just yet!! :wink: However I did work on getting it to press...

Re: Robot arm - free for postage

For those of us who have a DataCentre with a USB port on the front, I wonder how simple it would be to somehow control it that way? So the short answer to that, thanks to Flaxcottage, is quite simple really! https://stardot.org.uk/forums/viewtopic.php?f=3&t=4337&start=30#p69633 Using the informatio...

Re: Odd reset/Atom MMC behaviour

Can you try a small test: - Power up the Atom (so AtoMMC appears) - Press BREAK (so AtoMMC disappears) - Now remove the SD Card then Reinsert it - Press BREAK Is AtoMMC back now? Yes. That does indeed make it come back! :D So I should basically just try a different SD card then? Ha, well that turne...

Odd reset/Atom MMC behaviour

Hi All, Last weekend I fitted one of SirMorris' Atom MMC's to my Atom. It seems to be working well and I'm very impressed with it. Only odd thing I get is that when I press 'break' it seems to stop running. It is active at power on and displays ACORN ATOM + ATOMMC2 all fine. However if I press 'brea...

Re: Today I received.....

If you have a Datacentre it can be operated via the USB port. I got mine working with a joystick. They have no feedback, however, and cannot be used for repetitive tasks with accuracy. Fitting small potentiometers to each 'joint' and using the Analogue Port for feedback could produce a fun system. ...

I have replaced the 7805's with small switchers.
That's interesting, and I assume therefore that you're still able to use the original 8v power supply? That would be something I would consider doing I think.
