Thanks to Raspberry pi and 3D Printer you’ll be able to recreate a perfect replica of the iconic Commodore PET model 8032 launched back in 1977. The Commodore PET with the first personal computer sold to the general public and was equipped with a built-in keyboard, screen and cassette deck and was priced at $795…
Few days ago tomshardware.com has published an interesting interview to Raspberry Pi CEO Eben Upton about the fascinating story behind the most famous SBC for makers. In this post Eben Upton has revealed 10 things you may not have known about Raspberry Pi, so let me shortly summarise what he told to tomshardware: Raspberry Pi…
Max Williams has just shared on Hackster.io schematics, PCB layouts, CircuitPython code via GitHub, BoMs, measurements and photos about his new open source modular HiFi amplifier. It uses an Adafruit ItsyBitsy M0 Express running CircuitPython to make great music. The preamplifier is made up of a number of connected components: MDAC attenuator (PCB, code): Controls the volume Input selector (PCB, code):…
Aptly named TWIST the open source environmental monitoring system is capable of sending tweets and collecting meteorological data thanks to its include gas, rain, light, temperature and humidity sensors. “Meet Tweeting Weather IoT Station aka TWIST – a DIY, Open-Source Environmental Monitoring and Meteorological Data Acquisition Platform. The purpose of TWIST is so that individuals…
Created by Speeko, the 3D printer frame kit offers an easy way to build an accurate 3D printer and provides everything you need to create a foundation on which you can build a reliable and accurate desktop 3D printer. “The Easy Frame is a machine frame for 3D printers, based of the measurements of the…
Hardkernel failed to deliver the $100 Rockchip RK3399-based Odroid-N1 developer board last year due to component shortages. But it’s now back with a successor, the Odroid-N2, which is cheaper and performs significantly better in benchmarking tests. The ace up the $63 board’s sleeve is its performance, courtesy of four 1.8GHz Arm Cortex A73-based processors and…
YouTuber Electronoobs has just created an Arduino Nano multimeter device. Using a small OLED screen in combination with the Arduino Nano together with a couple of buttons and 16-bit ADC for precise measurements the multimeter is able to display voltage, resistance, current, and it’s also capable of reading capacitance and inductance. Power is provided by…
SinoVoIP has just unveiled their latest Banana Pi BPI-M4 board powered by Realtek RTD1395 processor, following Raspberry Pi 3B+ form factor, and adding an M.2 key E socket with PCIe 2.0 and USB 2.0 signals. The new SBC by SinoVoip has a 92 x 60mm footprint and a 40-pin, Raspberry Pi compatible expansion connector. The…
The SuperB module is made by Macchina, the company that describes its product as the perfect marriage of two of hardware’s ubiquitous names : the Bee form factor and ESP32. In fact the SuperB module allow you to easily add wireless and Bluetooth connectivity to your project. SuperB marries two of hardware’s ubiquitous names – the “Bee” form factor and…
Developed by students at the California Institute of Technology, Poseidon is an open source alternative to commercial syringe pump and microscope system. The Poseidon microscope consists of a Raspberry Pi, touch screen module, and commercially available digital microscope housed in a 3D printed stage. This device offers a large and clear view of the object…
The Delta 5 Race Timer is an open-source multi-node timing system that uses the video signals from FPV vehicles to determine when they cross the start/finish line. The heart of the system is a Raspberry Pi, and each node has a dedicated Arduino Nano and RX5808 module. The Arduinos are themselves connected to the Raspberry Pi over…
Field-programmable gate arrays (FPGAs) are a very different to a regular microcontroller board. With a microcontroller you have control over is the software, the code that runs on the chip, but with an FPGA you start with a blank slate and design the circuit rather than write the code that runs on it. There is…
