I thought it may have been a war between conventional and electron current flow.
There is a high voltage DC submarine cable between the Australian mainland and Tasmania:

Re: Selecting a Chromebook
emmc is certainly the cheaper of the two memory devices. so if they are advertising it comes with SSD and in fact has emmc, then I would consider that false advertising. you could actually program arduino's on a chromebook with codebender: https://codebender.cc/ however they are closing down codeben...

Re: Survey of Video Generation Possibilities
I have made different fonts for LED screens before and I know what you mean about trying to get readable characters in the fewest pixels possible. I found you can get alot of characters in a 3x4 pixel grid however there are some that just don't work correctly like M and W

Re: Any way to get this sensor working again?
Have you tried measuring the voltage of the 5V power supply when everything is running? If the power supply can't handle the amount of current needed by the motors, then the voltage will drop down quite a bit below 5V.

Re: Christmas ornament project
I just found some code from a number of years ago which should really help you out. It uses a different microcontroller however you should be able to simply change the ports to the ports you are using for the RED cathodes, Green cathodes and the common anodes - then change the microcontroller detail...

Re: Christmas ornament project
I apologise for not being around much, hopefully this coming weekend i'll have some spare time to sit down and have a good look at your code and even test it out on some hardware.

Re: Building a 24x24x24 led cube
I imagine that would have been quite expensive to have PCB's made that large - certainly seems to be a much quicker way of making an LED cube compared to using individual wires though!

Re: Christmas ornament project
just so I am following along, you currently have nothing being displayed on the matrix - and the circuit you are using is exactly the same as the design files you posted, is that right?

Correct me if i'm wrong, but could this be used in place of an ultrasonic transceiver?

Re: Edison Bulb Still Burning After 100-Plus Years
I guess they rely on consumers not bothering to check hour counts so they can really market it however they want and people won't do anything about it.

Re: Help wanted 74HC595 LED sign
One question I have is that you need to be entering in at least one logic 1 to begin with so this data can be shifted through the 595 chips. How does this logic 1 get in there to begin with?
