It has been about one year since the announcement of ESP32 SoC and the beginning of its beta testing for some developers. Last Month we covered the release of ESP-WROOM-32 module datasheet, which promised that “New SDK features, tutorials and example applications will be released over the next few months.”. The ESP-32 datasheet was released […]

A pocket watch, tucked into a waistcoat pocket and trailing a long chain, is a retro-hip accessory. A pocket watch gutted of its mechanical innards and updated as a smart appliance might be a horological abomination, but would still be a cool hack. A pocket watch converted to a digital Enigma machine is in a class all

The mighty Class-D amplifier—build one yourself and be amazed by its efficiency. The heat sink barely gets warm! Have you always wanted to build your own audio power amplifier? An electronic project where you not only see the results but also hear them? If your answer is yes, then you should continue reading this article on
Arduino enthusiasts searching for a board that supports connection via Bluetooth rather than USB may be interested in the Z-duino Bluetooth Arduino board recently launched via Kickstarter. Compatible with the Arduino Uno the new Bluetooth board allows you to remove the need for a USB cable connection making your development and applications more flexible. “You can upload
Z-Duino Arduino Bluetooth board removes the need for a USB connection Continue Reading
Certain hobbies come in clusters. It isn’t uncommon to see, for example, ham radio operators that are private pilots. Programmers who are musicians. Electronics people who build model trains. This last seems like a great fit since you can do lots of interesting things with simple electronics and small-scale trains. [Jimmy] at the aptly-named DIY
While making my mini table saw I bought a 12 V motor speed controller module from eBay. Fair enough, I thought … that was an easier and straight forward solution. But then I decided to make my own. I did some hunting around on the interweb and found a pretty good starting point in Circuits
Researchers want to give a 25-core open-source processor called Piton some serious bite. The developers of the chip at Princeton University have in mind a 200,000-core computer crammed with 8,000 64-bit Piton chips. It won’t happen anytime soon, but that’s one possible usage scenario for Piton. The chip is designed to be flexible and quickly
Open source 25-core processor can be stringed into a 200,000-core computer Continue Reading
For aspiring experimenters, creators, and tinkerers, you must start your journey as a maker with the right tools. Arduino, the wildly popular open-source microcontroller manufacturer, provides you the tools to remotely control your light switches and appliances, as well as build small robotics in your own home. You don’t need any special knowledge base or

A situation many can relate to: an empty smartphone battery and no outlet around! That’s exactly why I recycled an old laptop battery into an USB power bank. Follow the link for the full article with close ups of the electronics and insights into the building process. This article will show you the basic powerbank
Measurements from the real world often contain noise. Loosely speaking, noise is just the part of the signal you didn’t want. Maybe it comes from electrical noise: the random variations you see when calling analogRead on a sensor that should be stable. Noise also arises from real effects on the sensor. Vibration from the engine
