The design of the rover left me with a question about DB1. The NASA rover first brings the battery power to two voltage regulators (5 and 12 volt) and...

The Rocker-Bogie assemply is elegant. The total cost to build the rover is several thousand dollars (at least two). I see various groups are sharing...

@robo-pi what a fascinating concept for a puzzle. The notion of parts that can be assembled in two ways is challenging enough regardless of what the t...

I think they are torx screws.

Nice addons. And of course lights are cool. The Ryzen motherboards pretty much all have a connector for LED strips now, and some of the motherboards h...

There was some discussion about fuse sizes. It seems like some experimentation is going to be needed before we know best values, so an assortment is r...

I just did the firmware update on my rpi4. This update is still in beta now, but they also provide the script to put it back to the default version so...

Don't forget to update the firmware - it saves 3-5 degrees for the USB chip which is a good thing.

As you may know the desktop interface flashes a red thermometer when the board goes above 80C and the thermometer icon goes full red if it goes above ...

That definitely looks like a fun project. How far along are you with the design for electronics and such?

Here is a benchmark study on rpi4 and heat. In general it will benefit from active cooling. It will get substantially hotter than a pi 3. And there is...

One other thought. I know some people use a smart phone to detect initial state of the sides and communicate back to the solver by bluetoooth...

@squeaky Well that’s an interesting challenge - algorithm versus looking up the answer using Cube Explorer (). While the algorithm probably will take ...

Incidentally, most machines solve the cube before they make the first move, so they know in advance the exact number of moves required. It is similar ...
