Tiny Professional Microphone Preamplifier
https://www.electronics-lab.com/project/tiny-proffesional-microphone-preamplifier/
This board has been designed around INA217 low distortion, low noise instrumentation amplifier. The INA217 is ideal for low-level audio signals such as balanced low-impedance microphones. Many industrial, instrumentation, and medical applications also benefit from its low noise and wide bandwidth. Unique distortion cancellation circuitry reduces distortion to extremely low levels, even in high gain. […]
Ultra thin supercapacitor for peak power assist
https://www.electronics-lab.com/ultra-thin-supercapacitor-peak-power-assist/
Peggy Lee @ newelectronics.co.uk discuss about MURATA’s ultra thin supercapacitor. The DMH series from Murata is said to be the lowest profile supercapacitor. The product is designed for peak power assist duties in wearable applications and various other devices. Measuring 20 x 20mm, the 0.4mm thick DMHA14R5V353M4ATA0 supercapacitor is claimed to be suitable for use […]
PWM POWER REGULATOR
https://www.electronics-lab.com/pwm-power-regulator/
pinko @ blog.exrockets.com wanted to regulate the power to a resistive load so he decided to build a PWM power regulator based on PIC18LF2550. In order to synthesize chlorates and perchlorates in the home lab it is always good to have a way to regulate the current flowing through the electrolyte. Because the load is […]
A Mass Programming Bench for ATMega32u4 MCUs
https://www.electronics-lab.com/mass-programming-bench-atmega32u4-mcus/
“limpkin” @ limpkin.fr wanted to program some thousand of MCUs so he decided to build his own programming bench. He writes: As you may know I started the Mooltipass offline password keeper project more than 2 years ago. Together with a team of volunteers from all over the globe I created two Mooltipass devices which were […]

GPS RECEIVER TO FM RADIO (88-107 MHz) AUDIO + RDS TRACKING V2
https://www.electronics-lab.com/gps-receiver-fm-radio-88-107-mhz-audio-rds-tracking-v2/
pinko @ blog.exrockets.com has build a GPS receiver to FM radio based on PIC18LF2553. He writes: Today I made some modifications to this is a new project for a GPS to FM radio tracking device for rockets i.e. the V2. The initial design lacked the antenna impedance matching circuit which caused problems with the end […]
MyPart, An Open Source Portable Air Particle Counter
https://www.electronics-lab.com/mypart-open-source-air-particle-counter/
One of the most harmful airborne pollutants with respect to human health is particulate matter. Air particle counters are used to determine the air quality by counting and sizing the number of particles in the air. This information is useful in determining the amount of particles inside a building or in the ambient air. It […]
AC Motor Speed Controller for Modern Appliances Using LS7311
https://www.electronics-lab.com/ac-motor-speed-controller-modern-appliances-using-ls7311/
The project specifically designed for motor speed control application in appliances such as blenders, etc. Tact switches provided for selecting/indicating from 1 to 10 power levels ( Speed Levels). The project is ideal for universal and shaded-pole motor speed control for modern appliances design. Eliminates awkward mechanical switch assemblies and multi-taped motor winding. Features 10 […]
TP4056 3V3 Load Share Upgrade
https://www.electronics-lab.com/tp4056-3v3-load-share-upgrade/
A lot of project are battery powered and some of them need dual battery links. Robert on hackaday.io had shared his new project that shed light on this issue. He built an load sharing addon board with the ability to charge the battery while the project is operating. Many Chinese charger boards are out there […]
ZeroPhone – a Raspberry Pi smartphone
https://www.electronics-lab.com/zerophone-raspberry-pi-smartphone/
Arsenijs build a Pi-powered open-source mobile phone (that you can assemble for 50$ in parts). Currently, it costs about 50$ in parts, and all the parts are available on eBay. No BGA or other difficultly solderable ICs are used (with the obvious exception of Pi Zero). User interface is written using Python, and there’s a […]
