Bangle.js: the hackable Smart Watch
https://www.electronics-lab.com/bangle-js-hackable-smart-watch/
While Python currently sits atop the throne of the most popular programming language in the world, languages like javascript have been creeping around the throne with different frameworks and APIs that have taken the language beyond use of web development. This was evident in Espruino as it opened up the doors to the use of […]
Free Elektor Article: 0-30V Lead-acid Battery Activator
https://www.electronics-lab.com/free-elektor-article-0-30v-lead-acid-battery-activator/
A well-known electronics store has been selling a very simple lead-acid battery activator for many years. Although I can’t prove it, my lead-acid batteries do seem to last longer since I started using the activator. The principle behind this circuit is very simple. The battery is loaded with a current of about 100 A for a […]
HyperDisk: Pocket-sized & High-speed Portable SSD [Attention: SCAM reported]
https://www.electronics-lab.com/hyperdisk-pocket-sized-high-speed-portable-ssd/
Physical storage drives have not changed a lot over the years. They have improved in terms of storage capacity and technology but they are definitely still a bit bulky (compared with how small things are becoming) and relatively slow. To offer an improvement to what is currently in the market, GrowthLabs recently announced the launch […]

Even with the advent of several file-sharing platforms and the proliferation of internet access to enable their use, the “old” regular way of moving a file from one place to the other via USB drives is still in vogue. Especially for large files like the video and picture contents which creatives need to move around […]
Multi-output Power Supply Based on LM2576HV-ADJ
https://www.electronics-lab.com/project/multi-output-power-supply-based-lm2576hv-adj/
This is a multi-output power supply based on LM2576HV-ADJ and LM317 IC. The power supply provides 3 outputs with input supply up to 55V DC. Output (O1) is adjustable up to 24V DC and load current of 2A, Output (O2) is adjustable to 1.2V-24V with load current up to 500mA and Output (O3) adjustable 1.2V-24V […]
AC Waveform and AC Circuit Theory
https://www.electronics-lab.com/article/ac-waveform-and-ac-circuit-theory/
Introduction When talking about current or voltage, these signals can be fitted into two main categories : DC and AC. DC states for “Direct Current“, this definition regroup the signals that are constant in time : their amplitude and sign (+ or -) remain unchanged. AC states for “Alternating Current“, these signals are alternating between […]
PocketAdmin – Keystroke Injection Device
https://www.electronics-lab.com/pocketadmin-keystroke-injection-device/
This is a keystroke injection device (also called badusb). It is similar to a well-known USB rubber ducky made by hak5, but has much extended functionality, lower price and is also completely open source. It looks and feels like an ordinary USB flash drive, but acts as a keyboard that types in a preprogrammed payload. […]
