As a prior amateur boxer, I have always wanted to find a way to record and measure the strength and velocity of my punches. So, when I decided to put together my own project using Adafruitâs ESP32-S2 with TFT.
I have been working on Adafruit iOS apps, specifically PyLeap, an app used to download project resources and transfer them directly to the userâs device via BLE or Wi-Fi. While working on the app, I became interested in creating my projects and decided to use my knowledge of iOS to make something related to my passion for boxing.

Scientists believe that a dogâs sense of smell is somewhere between 10,000 to 100,000 times more acute than that of humans because for every scent receptor a human has, a dog has about 50.
Now, researchers at Tel Aviv University (TAU) have developed a biological sensor whose sensitivity rivals that of dogs. The sensor sends electrical signals as a response to the presence of a nearby odor that the robot can detect and interpret.

Digi-Key Electronics and Make: are pleased to release the updated Boards Guide and companion Digi-Key AR augmented reality app available in both the Apple App Store for iOS devices and the Google Play store for Androidâą-based mobile devices.

Meet Alpakka: a customisable, open source gaming pad with additional features to improve performance and user experience. Input Labs designed it and they are a new organisation creating open source 3D-printed gamepads with a focus on accessibility. We quite like their mission statement: âDemocratizing videogame controllersâ.

While most of us associate Morse code with old-timey telegraphs, it is still in use today. The benefits now are the same as they were a hundred and fifty years ago: it is an incredibly resilient way to encode information that works with a variety of different transmission methods. But what if you have trouble operating a standard Morse code key? This CWvox device, designed by Kevin Loughin (AKA KB9RLW), translates voice commands into Morse code keying.

Most of us learn to read digital clocks first, which display the time in obvious numbers. Analog clocks are often learned later, with the hands taking our young brains a little longer to figure out. Once youâve grown into a 1337h4XX0r, though, youâre ready to learn how to read a binary watch. Then you can build your own, just like [taifur] did.

Itâs been a while since I last wrote about my ThinkPad T430 that was tasked with being a home server. After doing some experiments with my setup a couple of times, it is once again the main server for all my self-hosting needs. However, this time I have made some adjustments.

The die photo below shows the 8086 microprocessor under a microscope. The metal layer on top of the chip is visible, with the silicon and polysilicon mostly hidden underneath. Around the edges of the die, bond wires connect pads to the chip's 40 external pins. I've labeled the key functional blocks; the ones that are important to this discussion are darker and will be discussed in detail below. Architecturally, the chip is partitioned into a Bus Interface Unit (BIU) at the top and an Execution Unit (EU) below. The BIU handles memory accesses, while the Execution Unit (EU) executes instructions. Both are stopped by a halt instruction.
