Mclaneinc Posted June 17, 2019 Share Posted June 17, 2019 Hi DrV, I spoke to the guy and he said there is a switch on the SDrive and a power socket, he siad the switch choses where the supply voltage comes from so I presume this stops both being connected at the same time, The only thing that has now thrown me is that he said it uses a standard multi PSU plug in the wall type thing with the numerous heads but he said it needs to set to 9V dc center pin positive which I fully understand but varies from the 5V I've seen..

flashjazzcat Posted June 17, 2019 Share Posted June 17, 2019 This is an Arduino board, right? If so, I believe they can run off 6-20V DC. 1 Quote Link to comment Share on other sites More sharing options...

Great! I know a lot of folks are adding an external switch for that purpose. I’m too lazy - I just disconnected the SIO power wire inside my board. ? 5 minutes ago, flashjazzcat said: This is an Arduino board, right? If so, I believe they can run off 6-20V DC. Jon is correct - the standard USB PSU is 5V DC, the Uno wall-wart I use is 9V DC. Either will work just fine. Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted June 17, 2019 Share Posted June 17, 2019 Thanks guys....Much appreciated, didn't want to screw the thing on the first day of use... I did have a look for Arduino psu's on ebay and the ones I saw were 9v..Some variable voltages.. Again, thanks for all the help, back to normal chatter Quote Link to comment Share on other sites More sharing options...

Again, thanks for all the help, back to normal chatter Just as a note, the easiest way to power those and not put another power supply on you desktop is to connect the USB cable to a USB charger (*everyone* has at least two of those lying around). Heck, the power strips/bars are being sold now with USB ports on them. It's clean power, you don't have to worry about the wrong voltage or polarity. Easy peasy. 2 Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted June 17, 2019 Share Posted June 17, 2019 Thank you kind sir, I know my daughter has at least two of those or should I say HAD two of those Its arriving Friday (hopefully) will check it out then and see what is the the table here...I'm going to have to have a spare USB lead anyway for firmware updates so it may as well go in a charger but lets see what I receive and go from there.. Great help from all, appreciated!!! Paul. Quote Link to comment Share on other sites More sharing options...
+DrVenkman Posted June 17, 2019 Share Posted June 17, 2019 I got my replacement screen today and I'm back up and running perfectly with the SDrive-MAX. With MrRobot's board design installed, there's no issue whatsoever sharing the bus with my real floppies or other SIO devices. 3 Quote Link to comment Share on other sites More sharing options...
NISMOPC Posted June 17, 2019 Share Posted June 17, 2019 (edited) Not sure, but thinking I fried my UNO board. Last night got the bright idea to use a universal power supply at 12V. SDrive-Max powered up, screen came on then within seconds, the screen went completely white in color. Unplugged it and then chose 9V. SDrive-Max powered up like normal, but I am no longer able to use the touchscreen, except to maximize/minimize the command line window (READY prompt) by touching random areas on the screen. I can't get into [Cfg] or anything. SDive-Max still loads the D0: atr file and I can still operate using my 8-bit onscreen commands, but that's about it. A few months ago, I lost 1TB harddrive with all my files, so I downloaded Arduino IDE 1.8.9 and installed the proper CH340 driver. The COM 3 port is showing as being the active port. I am unable to upload any sketches, etc etc etc. Any thoughts? Fried board? Error message for all attempts is as follows: (BLINK test) Sketch uses 930 bytes (2%) of program storage space. Maximum is 32256 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

+Stephen Posted June 18, 2019 Share Posted June 18, 2019 Think that should only use 5volts - I can imagine 12V doing some damage. Quote Link to comment Share on other sites More sharing options...

The SDrive-MAX Arduino has several options for power. - SIO 5V - USB 5V (w/SIO 5V wire removed) - AC/DC 7V-12V (w/SIO 5V wire removed) I was using the SIO 5V, but noticed low power flickering, so I decided to remove the SIO 5V power wire and use the AC/DC input. That is when things went south... Quote Link to comment Share on other sites More sharing options...
Forrest Posted June 18, 2019 Share Posted June 18, 2019 From the reviews I've read, some Arduino Uno's with the surface mount Atmega328 processor will only accept 7-9 VDC on the power jack. 1 Quote Link to comment Share on other sites More sharing options...

Forrest Posted June 18, 2019 Share Posted June 18, 2019 I would measure the voltage on your universal power supply with a multimeter. I've seen some overshoot 25% - which is not acceptable. The output voltage should measure no more than 10% over the rating. Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted June 18, 2019 Share Posted June 18, 2019 I'd hope for a 5% difference maximum especially under load. Quote Link to comment Share on other sites More sharing options...

NISMOPC Posted June 20, 2019 Share Posted June 20, 2019 I'm back in action. Picked up new board locally from MicroCenter. It's an Inland branded board on sale for $7.99. There was nothing wrong with the touchscreen. Just the UNO board. Using a 1n4148 inline and 5V USB power. All SIO devices are working. Since this is not a micro USB version like my original build, need to get another case printed or file the slot open... 1 Quote Link to comment Share on other sites More sharing options...

If you don't have any fine files, you can buy a cheap "Kobalt" branded set at Home Depot for like $10 that includes flat, round, half-round and triangular files. I doubt they're terribly long-lasting but for plastic they're great. Glad your screen is in good shape! Excellent job on finding a local board cheap. Nothing like that around here - it's 2-day Prime from Amazon or 6-week slow-boat from China here. 2 Quote Link to comment Share on other sites More sharing options...

I would love to have more memory (Arduino mega) to allow more features. An option for a bigger screen would be cool. What do do you envision this new device doing differently than the SDM?

Mr Robot Posted June 21, 2019 Share Posted June 21, 2019 (edited) I was going to add a super capacitor to it so that the UNO powered by SIO doesn't power off when you power cycle the Atari. No more saving your settings to remember the disks and hoping it will startup faster than the Atari does when trying to boot. That should get rid of the need for an external power supply. The supercap is a tight fit, UNO board layouts vary, I want to make it fit on the most common boards, the boards I have are not the most common so the components on it aren't where they are for most people. If I make it fit my UNO's it will be too thick for some oithers. I want to get the most common boards to prototype against so I was asking for links to see if I could get a common standard.

This is a good example, you see that metal can by the 6 pin connector? is that in that position for everyone? If it is I need to avoid it because it stands too high. It looks about the same place as the UNO's I have, but mine are different, they only have 2 rows of headers next to that connector and they have a mirco USB. Other people have other layouts too! Here it is with the supercap I have to find a home for... Edited June 21, 2019 by Mr Robot Add Pics Quote Link to comment Share on other sites More sharing options...
+slx Posted June 21, 2019 Share Posted June 21, 2019 I came across the non-socketed version on Aliexpress and this socketed version on Amazon (which does not need the sub-board). The oscillator can needs on the former needs to be insulated when the sub-board is installed. Quote Link to comment Share on other sites More sharing options...
Mr Robot Posted June 21, 2019 Share Posted June 21, 2019 The DIP versions and Genuino's I wont be able to do at all, to make this work I'll need the pin holes you get on the knockoffs inside the pinsockets to mount to. Quote Link to comment Share on other sites More sharing options...
