Export Eagle Libraries With SnapEDA
https://www.electronics-lab.com/export-eagle-libraries-snapeda/
Although the new Eagle subscription model by Autodesk will bring much-needed features to the software, many users after the announcement had decided to move their work to other alternatives, such as KiCad, Altium, Cadence, etc. One of the challenges was to convert the libraries made by Eagle to be compatible with other software programs. SnapEDA solved that […]
Increasing Battery Life With UB20M Voltage Detector
https://www.electronics-lab.com/increasing-battery-life-ub20m-voltage-detector/
Engineers at the University of Bristol have developed a three terminal pico-power chip that can cut standby drain in sensor nodes – even compared with today’s low-power microcontrollers. It does this by replacing the low duty-cycle sleep-wake-sleep pattern used on MCU-based sensor monitors, with ‘off’. A voltage detector powered by the sensor – there is […]
12V @ 120mA Transformerless Power Supply
https://www.electronics-lab.com/12v-120ma-transformerless-power-supply/
The circuit provided here is a transformer-less non-isolated power supply which is capable of delivering an output of 12V at 120mA current for an input voltage varying from 85VAC-265VAC. The LNK304 is the heart of this circuit which supports buck boost and flyback topologies. This project is low in cost and simple when compared other […]
TI claims first for zero-drift, zero-crossover op amp: precision & linearity
https://www.electronics-lab.com/ti-claims-first-zero-drift-zero-crossover-op-amp-precision-linearity/
by Graham Prophet @ edn-europe.com: With precision and high input linearity in a single high-performance device, Texas Instruments says it has the first operational amplifier (op amp) to offer both zero-drift and zero-crossover technology. The OPA388 op amp maintains high precision across the entire input range for a variety of industrial applications, including test and […]

Teardown of a Peaktech 6225A
https://www.electronics-lab.com/teardown-peaktech-6225a/
Teardown and analysis of a Peaktech 6225A power supply from ElectroBob: I got a Peaktech 6225A power supply to power some things, as it seemed like a good deal, going beyond what one might find normally in these types of supplies: more display resolution and supposedly, lower noise. For this price, this supply is a good […]
