HiFi Passive Preamp
https://www.electronics-lab.com/hifi-passive-preamp/
FutureSharks @ github.com has build a very nice HiFi passive preamplifier controlled by an Arduino board. It has the following features: Volume control and input selection via encoder and Apple remote. Uses a 256 step R2R relayed based attenuator. Completely passive. Only 5V power required. Adafruit NeoPixel shows volume level with colour. Sleep mode with low […]
MagSpoof – Wireless credit card/magstripe spoofer
https://www.electronics-lab.com/magspoof-wireless-credit-cardmagstripe-spoofer/
MagSpoof is a device that can spoof/emulate any magnetic stripe or credit card you currently own. It can work “wirelessly”, even on standard magstripe/credit card readers, by generating a strong electromagnetic field that emulates a traditional magnetic stripe card. Note: MagSpoof does not enable you to use credit cards that you are not legally authorized […]

blog.squix.ch has published there code for a ESP8266 based weather station. More details here: It is not yet working as smoothly as I want it to work but maybe some of you can help me getting rid of the nasty issues that were bugging me for the last few weeks. The README on github contains […]
Raspberry Pi tutorial: Use SSH to in order to remote control your Raspberry Pi
https://www.electronics-lab.com/46297-2/
SSH protocol can be very useful if we want to remote control our Raspberry Pi. I am using a Raspberry Pi A+ board in this video but you can use any Raspberry Pi board you like. So far, when we wanted to use our Raspberry Pi, we were using a keyboard, a mouse and a […]
Microcontrollers with USB interface are common, but…
https://www.electronics-lab.com/microcontrollers-with-usb-interface-are-common-but/
FTDI.FT-X series USB to serial bridges can be still reasonable option even for today. Microcontrollers with USB interface are common nowadays. Manufacturers provide source codes for USB device classes like CDC, HID, Mass storage and DFU. . Even in this case, programming USB communications may not be a trivial task. If it is only required […]

https://www.electronics-lab.com/contactless-infrared-thermometer-pyrometer-using-mlx90614-and-msp430/
mcs.uwsuper.edu has build a contactless thermometer based on MLX90614 sensor and MSP430 mcu. The device is designed for contactless measuring and monitoring temperature of objects. It is built on Melexis MLX90614 sensor and can measure temperatures in the range from -70°C to +380°C with 0.5°C accuracy and 0.01°C resolution. The period of measurements can be […]
4 Digit Thermometer using DS18B20 and PIC16F628A
https://www.electronics-lab.com/4-digit-thermometer-using-ds18b20-and-pic16f628a/
moty22.co.uk has a PIC16F628A based thermometer using DS18B20 digital sensor. Counter based on PIC16F628A . Included C code and circuit diagram. Displays -55 to 125 centigrade. The temperature is read every 15 seconds, can be changed in the code. The math is using integers to calculate the degrees and the tenths of degrees are calculated separately. […]
