Software Defined Radio (SDR) shield for Arduino
https://www.electronics-lab.com/software-defined-radio-sdr-shield-for-arduino/
by Clemens Valens @ elektormagazine.com The new SDR board was created by Burkhard Kainka, the designer who also did the first SDR project. The antenna preselector of the original board has been removed while the CY27EE16 programmable oscillator was replaced by the Si5351 from Silicon Labs. The Arduino board takes over the functions of the FT232R […]

Alex @ obddiag.net has published a new open source OBD adapter which provides you a serial interface using the ELM327 command set and supports all OBD-II standards. The adapter kit schematic is shown here. It is built around NXP LPC1517 Cortex-M3 microprocessor with 64 kB program memory, but can accommodate another chip from same family like […]
How to measure mass of the Earth using Arduino
https://www.electronics-lab.com/how-to-measure-mass-of-the-earth-using-arduino/
victoryking @ instructables.com has posted a nice physics and arduino tutorial on how to measure the mass of earth. This is an indirect method to calculate the mass of earth by measuring acceleration due to gravity with the help of arduino. One fine day, I was weighing my self on a weighing scale. Suddenly a […]

https://www.electronics-lab.com/featherhab-balloon-tracker-firmware-hardware-source-released/
Ethan Zonca has released the firmware and hardware of FeatherHAB. FeatherHAB is a small and inexpensive ballon GPS tracker. FeatherHAB is a lightweight, small, and inexpensive balloon tracker. It tracks the location of a balloon with GPS and broadcasts the balloon’s position to the APRS network on 144.390MHz. The tracker is built around a Ublox […]
ATmega8 Thermocouple Thermostat
https://www.electronics-lab.com/47832-2/
morethanuser.blogspot.com has published a thermocouple thermostat based on ATmega8 and MAX31855KASA Thermocouple to digital converter IC from Maxim. Here is a circuit, I used popular thermocouple type K and MAX31855KASA+ to interface it. I could also put some op amp, and connect to Atmega8’s ADC, but 31855 is for lazy people and has everything inside, […]
