Adafruit’s PropMaker Feather is a microcontroller board designed specifically for building props with electronic features. Thus, what better way to show it off than by building a nifty replica of the most menacing AI ever to roam this solar system? That’s right, it’s the Adafruit HAL9000 build! Following the 80/20 rule, this version is intended to […]

In retrocomputing circles, it’s often the case that the weirder and rarer the machine, the more likely it is to attract attention. And machines don’t get much weirder than the DEC Rainbow 100-B, sporting as it does both Z80 and 8088 microprocessors and usable as either a VT100 terminal or as a PC with either

So here is how i made my foot pedal used to start Linux terminal using an Arduino. It’s made because I am board of pressing the terminal icon with my mouse. P.S. Sorry for my English. I am from Croatia. Tools needed: -Soldering iron and some solder -Wire clippers or any other cutting tool -Screwdriver

i2SOM has launched a PanGu SBC based on STMicroelectronics (ST) STM32MP1 series SoC. The PanGu SBC list support for both Yocto and Debian and offers 1GB DRAM, HDMI, Ethernet, LCD, USB OTG, USB Host, TF Card, audio and other interfaces. The PanGu Board utilizes the STM32MP157AAA3 version of the SoC series. This version integrates a 650MHz Arm dual-core Cortex-A7 core and 209MHz Cortex-M4 coprocessor

This project is about an open-source, USB based, 10 digit seven segment display unit. This unit is specifically designed to work with POS systems and banking applications. Initially, this system is developed to work with PC based POS systems, and later it was modified to work with other applications. To simplify the communication interface this unit is designed to

A few days ago NXP has released a new version of their Eclipse IDE flagship: the MCUXpresso IDE v11.0. The previous v10.3.1 was released back in Feb 2019, and the 11.0 now in June this year matches up with the Fall university semester. I appreciate that the releases are about every 6 months, so this gives

In this project you’ll discover how to design and create a Multisensor Shield for the ESP8266 Wemos D1 Mini board. The shield has temperature sensor (DS18B20), a PIR motion sensor, an LDR, and a terminal to connect a relay module. We’ll start by preparing all the hardware and then program it. Watch the Video Tutorial This

This is a guide to using the motors and sensors from the LEGO NXT set with a Parallax Basic Stamp II or BS2. However, rather than just providing schematics and sample code for the BS2, I’ll be providing some theory on how the sensors work as well. This way, someone using an arduino or other

Theory of operation In series thermocouple soldering iron have a thermocouple in series with their heating element and thus only have two connections (actually one more which is electrically connected to the tip for ESD purposes). When a voltage is applied to the two terminals the tip heats, when unpowered the thermocouple voltage can be
