I’ve been working with Arduino boards for a number of years, as shown by the dates on some of my older blog posts. In that time I’ve only used boards based on the ATmega8 (like the …

Open source software that isn’t signed by an identified developer can cause headaches upgrading it on OSX. While working with the Arduino Due the first time, I downloaded 1.5 Beta …

The other night I happened to see a tweet come across my twitter stream from Joe Walnes (@joewalnes) about a resistor color code tool he created. You can find it at the clever …

Here’s a couple of quick tips to get around the Arduino IDE error message “Serial Port in Use.” These mostly apply to OSX, but since it is UNIX based, they may make sense for Linux …

Regulator Types Fundamentally there are two types of voltage regulators: linear and switching. The names come from how they operate and how they achieve voltage regulation. Linear …

Status: Completed GitHub: https://github.com/baldengineer/8x6-LED-Matrix-Shield Abstract After getting a couple of flashing lights working on a microprocessor, the next fun project …

Digital ICs like microcontrollers, memory, and shift registers need a stable voltage source to make sure they work as expected. Most circuits are designed with a voltage regulator …

When working with components like capacitors and inductors it is always helpful to know how to calculate a resonant frequency. This Resonant Frequency Calculator is an excellent …

When I was working on BinBoo (A Binary Clock), I decided I was going to create a custom enclosure with a laser cutter. The process took me a couple of iterations. The very first …

Recently I realized most of my projects were all Arduino-based. There are lots of other prototyping platforms available in the market, and the TI LaunchPad, based on the MSP430 is …
