Disconnect circuit for 12 volt lead acid and lithium batteries
https://www.electronics-lab.com/50967-2/
KA7OEI designed a circuit that disconnects the battery when it over-discharges. He writes: The avoidance of overcharging is usually pretty easy to avoid: Just use the appropriate charging system – but overdischarge is a bit more difficult, particularly if the battery packs in question don’t have a “protection board” with them. Lead acid batteries (almost) […]

Using Bluetooth LE in Products
https://www.electronics-lab.com/advices-using-bluetooth-le-products/
Jone Teel over Makezine walked through how to use BLE (Bluetooth Low Energy ), aka Bluetooth smart, in an electronic product. BLE, unlike classic Bluetooth, it’s not designed for big data transmission or streaming audio or video. BLE comes in SoC (System on Chip) ICs which combine a RF transceiver and a microcontroller running the […]
How to Upgrade Your ESP8266 SPI Flash to 4MB
https://www.electronics-lab.com/upgrade-esp8266-spi-flash-4mb-one/
ESP8266, the well known WiFi module contains an ESP8266EX SoC IC and an external SPI flash. This external SPI flash is used together with ESP8266EX to store user programs. The supported size of flash by ESP8266EX is up to 16MB but some of ESP8266 modules contain flash chips with low storage capacity like 512KB. In […]

Simple Arduino Radio with TEA5767
https://www.electronics-lab.com/simple-arduino-radio/
AxelP6 @ instructables.com has uploaded a new tutorial on how to make a simple arduino radio based on 2.2″ TFT ILI9225 controller, TEA5767 breakout board and Arduino MEGA2560. The radio can play a list of predefined stations and can’t scan through them. So, I was searching for a tutorial to create a simple Radio with […]
