400V – 5A Power Supply For Brushless Motor Drivers
https://www.electronics-lab.com/project/power-supply-brushless-motor-drivers/
Although the power supply design is specific to the Brushless Servo Drivers mainly for IPM Modules, the concepts and circuit design may be used for any power supply that requires high voltage output up to 400V DC and 5 Amps. The power supply is an unregulated design with an option to allow connection to either […]
A 32-BIT FISHINO board with WiFi, SD card, RTC, audio codec, LiPo and more
https://www.electronics-lab.com/32-bit-fishino-board-wifi-sd-card-rtc-audio-codec-lipo/
Boris Landoni @ open-electronics.org presents his 32bit Arduino Compatible board which has some nice features on board. He wrties: Our prototyping board acquires a 32-bit processor and sets the bar high, towards demanding applications that may take full advantage of the WiFi support, of the RTC and of the SD-Card, that make Fishino stand out from […]
Solar Power Module v2
https://www.electronics-lab.com/solar-power-module-v2/
Chip McClelland @ hackster.io published his solar li-po battery charger based on MCP73871 to manage the solar and DC charging of the LiPo battery, TPS63020 Buck-Boost Converter and Maxim 74043 LiPo Fuel Gauge. He writes: I build connected sensor which are often deployed in local parks where there is no access to utility power. Over the […]
A new type of flexible micro-supercapacitors
https://www.electronics-lab.com/new-type-flexible-micro-supercapacitors/
Researchers from Nanyang Technological University in Singapore build a new type of flexible supercapacitor that aims to be used in wearables and other portable electronics such as T-shirts charging mobile phones. The new type of capacitor is made with out-of-plane wavy structures of graphene micro-ribbons specially placed so that they don’t break when stretched while […]
Paperino, The ePaper Display Shield
https://www.electronics-lab.com/paperino-epaper-display-shield/
ePaper displays (EPDs) are becoming a trend in application, just like the display used in Amazon Kindle, for their low power consumption due to the to the underlying ‘bistable’ display technology. These displays can continue to show information without any power at all. It is only required while updating the display with new information, otherwise […]
FPV drone teardown
https://www.electronics-lab.com/fpv-drone-teardown/
Michael Dunn @ edn.com did a quick tear-down of his drone. The main processor is an ST STM32F031K6, an ARM Cortex-M0 with the usual cadre of peripherals, as well as a motor-control block (the leftmost large chip in Figure 2). Although at the lower end of the ARM continuum, it’s doubtless more than powerful enough […]
