Designing a Mini BillBoard using LED Lights(different colors) , Arduino and Bread Board. Thought of creating a mini billboard, that could display my name (“Josh”) . This is for one of the build nights (required us to use LED lights). This billboard would blink in out josh several times just like any big billboard. Here
DietPi recently released version 9.1, which among other changes includes new images for the Raspberry Pi 5, Radxa Rock 4 SE and NanoPi R5S/R5C & 6. The Radxa Rock 4 SE image was necessary because the Rock 4’s RK3399 SoC is subtly different from the RK3399-T’s SoC in terms of memory support, which prevents a Rock 4 image

We’ll take a wild guess and say that right now, within arm’s length of wherever you’re reading this, there’s something that was produced by injection molding. Look around; it’s there someplace, and whatever it is, thousands or perhaps millions of other identical artifacts were produced along with it, all by squeezing hot plastic into intricately

The widespread adoption of the CAN bus (and OBD-II) in automobiles was largely a way of standardizing the maintenance of increasingly complicated engines and their needs to meet modern emissions standards. While that might sound a little dry on the surface, the existence and standardization of this communications bus in essentially all passenger vehicles for

In CPU design, there is Ahmdal’s law. Simply put, it means that if some process is contributing to 10% of your execution, optimizing it can’t improve things by more than 10%. Common sense, really, but it illustrates the importance of knowing how fast or slow various parts of your system are. So how fast are

Fundraising is not always an easy process. People are getting solicited left and right, and simply asking people for donations at random just doesn’t cut it anymore. People have very short attention spans and there are so many different causes and organizations to give to. This is why you need to learn how to show

You can’t do much development without running into Git, the version control management system. Part of that is because so much code lives on GitHub which uses Git, although you don’t need to know anything about that if all you want to do is download code. [Dr. Torq] has a good primer on using Git with

Daniel Eichhorn @ blog.squix.org, shares his experience with some popular PCBA services and documents his finding on his blog. He writes: Until recently I believed that having PCBs assembled by a professional service is either too costly for small batches or not possible at all. That was until I realized that some PCB manufacturers offer
