Makerarm – The first robotic arm that makes anything, anywhere
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. […]
LTC4282 – High Current Hot Swap Controller with I2C Compatible Monitoring
https://www.electronics-lab.com/ltc4282-high-current-hot-swap-controller-with-i2c-compatible-monitoring/
The LTC4282 is an energy monitoring Hot Swap controller with dual MOSFET drive to enable 100A and higher current board designs. The LTC4282 ensures safe board insertion and removal from live 2.9V to 33V backplanes by controlling external Nchannel MOSFETs to gently power up capacitors, avoiding sparks, connector damage and system glitches. High current […]
