Re: Megatronics v2 problems
Yes I did solve the problem. There is a later u8g library that solved the compile issues, it's u8glib_arduino_ v1.1.15 zip found going to the u8g web page best. I found that adding a library from...

Will only make one suggestion: Make sure that the USB connector shield is NOT connected to ground by default. Provide a jumper for this purpose (if people want it), but don't make it hard wired. A lot...

This ground loop thing is right, but ignoring the shield doesn't help, you get the loops through the data lines anyways. In fact, I found connecting the housing to GND to be neccessary even in my low...

The schematic details are hard to see because of resolution, but i think i see some caps (100nF/10nF?) on every I/O pin? I think it drastically limits the use of such pins, by changing the pin...

NoobMan: Actually I aim for 12V tolerance as I hope 12V will be enough for my purposes. I agree you have to be careful with diodes and that is why I removed any part info in the schematic as I want to...

The printers you've mentioned use OLED displays, not LCD displays.
View ArticleRe: LCD-TFT Screen Ultimaker 2?
It's just a display to drive. Electrically it's easy. That said, the main issue is that the firmware is already fairly big, an driving an OLED display from an 8-bit Arduino with its limited...

Hmm now im just thinking what about "octoprint" ? maybe we could incorporate an OLED, because its also talking to ramps i guess, and its using the Raspberry PI. What do you think Cefiar ?

Hi, I have an LED power supply 12V-400W. The label specifies Input 170-260V - 50/60hz. The problem is I am in North America with 110/120V input. Will it work?

There are some multimeters that can read temperatures. Not all though - just some. Those will have come thermocouple probe as accessory, and designated place to plug thermocouple in it. But can not...

ok, thanks. I had in mind that some thermocouple came with adapters and you could use something like 1mV/deg. scale. I found some on ebay that looks good. for sake of interess : Scientific Digital...

I think the simplest thing you can to about USB ground loops is to arrange the layout in a way that makes any ground loop current not affect thermistor readings. Like this: [www.pasteall.org] Excuse...
