Max Ritter has pointed us to his latest project, the DIY-Thermocam, a open source thermal imager based on FLIR thermal sensor. The results are awesome! The device is based on the popular FLIR Lepton thermal sensor and uses a Teensy 3.2 mikrocontroller to display live thermal images on a nice 3.2 inch touch screen. The aim […]

Inside the ALU of the first ARM microprocessor


https://www.electronics-lab.com/inside-the-alu-of-the-first-arm-microprocessor/

Dave @ daveshacks.blogspot.co.uk takes a look inside the first ARM microprocessor and explains it’s design. With that in mind I embarked on my own attempt to reverse-engineer parts of the armv1. Some background knowledge of the processor’s architecture is helpful, and googling for “ARM Architecture Reference Manual” will lead you to very detailed descriptions of […]

UCload new PCB build


https://www.electronics-lab.com/ucload-new-pcb-build/

Sjaak has published a new PCB build, uC controlled dummy load: With no snow outside I finally got around to solder the 3rd PCB. It is the second revision of a microcontroller dummy load. It is loosely based on the arachnidlabs uc:load. It uses the same base ciruit and adds a microcontroller (PIC16F1825), rotary encode […]

Texas CC2538 based development board


https://www.electronics-lab.com/texas-cc2538-based-development-board/

Jelmer Tiete has designed a development board for the TI CC2538, that is available at GitHub: It’s a nice little system-on-chip with an ARM Cortex M3, 2.4 GHz 802.15.4 radio and it runs at 32 MHz. Perfect for all your favorite Internet Of Things (IOT) shenanigans. Contiki supports this chip pretty well, which means easy […]

Galvanic Skin Response System


https://www.electronics-lab.com/galvanic-skin-response-system/

The Galvanic Skin Response (GSR) is a property of the skin to exhibit electrical characteristics. It is also known as Electrodermal Activity (EDA), Electrodermal Response (EDR), Electrodermal Level (EDL), Skin Conductance Activity (SCA), Skin Conductance Response (SCR), and a lot more. The GSR utilizes the principle that skin property varies with the state of sweat […]
