These days I was thinking about a better PIC programmer that can work with Microchip MPLAB IDE software so that I can write my own programs or edit someone else’s programs. I found that there are numerous versions of the famous Microchip PICkit 2 on the web. Some of them are using the original schematic […]

This BLE smart car is completed based on our latest design Bluetooth 4.0 chiped- BLEDuino, L298 Motor shield, smart car body. The smart car production is simple, as DIY enthusiasts can complete their own smart car only in the form of building blocks, and the operation is also very simple, just controlling it via Bluetooth
The Bluetooth Special Interest Group (SIG) has published the specs for the next generation of Bluetooth devices. Bluetooth 4.2 has a few improvements that will be of particular interest to developers of IoT devices. The biggest change is support for an Internet Protocol Support Profile (IPSP) which enables IPv6 for Bluetooth. This means that wearable

Why make your own printed circuit boards when you can get them commercially made for low cost? For one, it can take one to four weeks to receive the boards. For prototyping, this can be a major hurdle. Each design iteration will then take a month or more, and a project may need many months

HRL Laboratories, based in Malibu, CA, recently tested a prototype neuromorphic chip with 576 silicon neurons aboard a tiny drone measuring 6×6×1.5 inches and weighing 93 grams. The project was funded by the Defense Advanced Research Projects Agency (DARPA). The drone, custom built for the test by AeroVironment of Monrovia, CA, flew between three separate

This tutorial back-to-basics video discusses the operating point (or quiescent point, Q-point, bias point, etc.) of a bipolar transistor (BJT) circuit, and how the choice of the circuit design can affect how sensitive the bias point will be to the value of Beta (current gain) of the transistor. Ideally, you’d want to use a circuit

Hey guys, I built another board, which is a 3-channel (RGB) LED driver based on an inexpensive chipset called PT4115 (you can find them on eBay or Aliexpress). The circuit is very simple and looks like Sparkfun’s PicoBuck. However, I used beefier components and a different chip. You may say it’s pretty much the same
