DS1307 RTC Module
https://www.electronics-lab.com/ds1307-rtc-module/
The module based on DS1307, The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I²C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is […]

Hacking a UART on a blood pressure cuff
https://www.electronics-lab.com/hacking-uart-blood-pressure-cuff/
moamindustries.com hacked an Omron RS8 blood pressure cuff by adding a UART interface to it. As part of a prototype developed 12 months ago I was tasked with reading measurements from a blood pressure cuff [sphygmomanometer] in real time. Not surprisingly there are no consumer level devices that have a serial interface because what ‘normal’ […]

Bob hacked a home weather station transmitter and made a home thermometer from it. He writes: Recently I’ve found this piece of electronic on the dumpster, it was looking interesting – compact case with battery holder, LCD display, temperature and humidity sensor. It has also radio transmitter, but I’m not interested in it since I […]
