https://www.electronics-lab.com/3a-variable-bench-psu-with-color-display/
by SHARANYADAS @ instructables.com: I am playing with electronics since i was a child and made numerous circuits.But still now,i didn’t made any power supply unit for general purpose use.So tired of making PSU for each circuit,I decided to make a stable Bench PSU for general purpose use with some enhanced features.I decided to made the […]
Electronic Live Capture Mousetrap
https://www.electronics-lab.com/electronic-live-capture-mousetrap/
A mousetrap is a type of animal trap specialize to catch small animals, particularly rodents like rats, mice, hamsters, etc. This project is a kind of mousetrap that is intended to keep a captured animal alive. In this way, the hunter can release the captured animal later to the wild. The PIC12F683 microcontroller acts as […]

https://www.electronics-lab.com/makerarm-the-first-robotic-arm-that-makes-anything-anywhere/
Makerarm just lauched on kickstarter. It’s a penknife for the DIY world, it can make almost anything by changing the toolhead! A complete digital fabrication system for makers everywhere: 3D print, laser, carve, plot, assemble, pick/place + more on your desktop! Makerarm works with interchangeable heads for countless applications. It 3D prints: Makerarm is not confined […]
The femtocell technology
https://www.electronics-lab.com/the-femtocell-technology/
by Slovati @ dev.emcelettronica.com: Femtocells are basically low-power wireless access points that operate inside licensed frequency bands for connecting standard mobile devices with a provider’s network, using a broadband connection such as the DSL or a cable connection (basically using the best Internet connection available at that point). A femtocell is therefore an indoor base station that […]
Fastest, highest-resolution DLP chipset for 3D print/lithography
https://www.electronics-lab.com/fastest-highest-resolution-dlp-chipset-for-3d-printlithography/
by Graham Prophet @ edn-europe.com: With its latest micro-mirror-based light-steering chip, Texas Instruments says, applications developers can innovate with more than 4 million micromirrors to enable high throughput digital imaging applications. Presented as its highest speed and resolution chipset for 3D printing and lithography applications, TI’s DLP9000X digital micromirror device (DMD) and the DLPC910 controller, offers […]
Programmable Home Security Alarm System
https://www.electronics-lab.com/programmable-home-security-alarm-system/
In this project we design low cost high performance programmable home security system using few LDR’s as an input sensors. When above sensor(s) get triggered system may dial the user specified phone number (using build-in DTMF generator) and activate the high power audio alarm and lights. All the parameters of DTMF generator, audio alarm and […]

Open Inverter, an open source micro-solar inverter
https://www.electronics-lab.com/open-inverter-an-open-source-micro-solar-inverter/
Ken Boak has been working on an open source micro-solar inverter project: We wanted to make a design that uses readily obtainable N-type FETS and an Arduino (more strictly a ATmega328P-PU on a breadboard) to generate the PWM signals and provide simple circuit protection, and load sensing. With the PWM signals generated in firmware it […]
LiFePO4 charger
https://www.electronics-lab.com/lifepo4-charger/
Markus Gritsch shared his LiFePO4 charger project in the forum: Since I really like using LiFePO4 AA and AAA batteries in some of my projects, I finally gave in and built a dedicated charger for them. Previously I used a lab power supply to mimic the constant current/constant voltage charging curve, which worked also fine. […]
