High-level programming languages do a great job of making a programmer’s job easier, but these languages often leave a lot of efficiency on the table as a compromise. While a common thought is to move into a lower-level language like assembly to improve on a program’s speed or memory use, there’s often a lot that […]

Ok, we’ll come clean. [Design Build Destroy] didn’t really add any memory to his Arduino Nano. But he did get about 1.5K more program space when compared to the stock setup. The trick? On some Nano boards and clones, the bootloader is set to use a large block of reserved memory, but Optiboot only requires

Isn’t it nice when you can hit two birds with one stone? That’s exactly what we’ve done as we approach both Arduino Day and Saint Patrick’s Day with our version of the Chug-O-Meter! We absolutely loved what the circuit.io team did with their Chug Meter but thought that we could add more to its survivability

There’s something about Reverse Polish Notation (RPN) and the calculators that use it. It calls to mind a time when a calculator was a serious tool, and not just a throwaway toy. Created in the legacy of such calculators by HP and Texas Instruments, [Simon Boak] shows off his SB116, sporting an Arduino Nano under the

FPGA Boards have grown to become one of the “favorites” of the Embedded community. They feature in all kind of applications ranging from automation to DIY Applications, however, typical FPGA boards still cost way more than some other popular boards like the Arduino Microcontroller boards (even though performance is incomparable!). This keeps FPGA boards out

So this is the Nanoleaf 2.0 which is a DIY version of the famous Nanoleaf RGB Triangular lighting setup. The goal here was to Recreate a Nanoleaf-like device with minimal spec and low cost, one that has all the basic RGB Glowing features and can be made easily. To accomplish this feat, I prepared this
In May, Arduino released a guide on how you can create a UPDI programmer for under $10. Now Dlloydev has posted a guide on Github how to make an Arduino Nano HV UPDI programmer. The Nano HV UPDI programmer will enable you to use the additional configuration settings for the UPDI pin without the fear of getting locked out from the MCU. The Nano

Summary This PCB (Printed Circuit Board) resembles the YouTube Play Button award that is given out to creators for reaching certain milestones such as 100,000, 1 million, and 10 million subscribers. When the switch is turned on, the user can scroll through 5 different modes by pressing the button on the top left corner. The

In the mid eighties synths manufaturers started a “less is better” process that led to barebones synths. This allowed the reduction of costs on the manufaturer side, but made the patching process tediuos if not impossible for the final user. Manufacturers themselfs and third party companies realized optional boxes full of knobs and/or sliders to
