Just a couple of months ago FriendlyElec introduced the NanoPi M4, which was then the smallest, most affordable Rockchip RK3399 based SBC yet. But now they have launched a $45, Rockchip RK3399 based NanoPi Neo4 SBC with a 60 x 45mm footprint, WiFi/BT, GbE, USB 3.0, HDMI 2.0, MIPI-CSI, a 40-pin header, and -20 to 70℃ support —…
Pi Supply, which has produced a variety of Raspberry Pi add-on boards, is now on Kickstarter to launch a series of IoT LoRa Boards that work with the Pi. The offerings include an IoT LoRa Gateway HAT board starting at an early bird price of 120 UK Pounds ($157) and a LoRa Node pHAT node board…
If you have to duplicate many SD cards for example to boot Raspbian on multiple Raspberry Pi board but you want to save money, probably you’d better build a SD card duplicator by yourself. This is exactly what Bob Brown, a retired senior lecturer, have done. You’ll first need some hardware, including a powered USB hub…
Seeed Studio is taking pre-orders for the new A.I. Thinker ESP32-CAM board with a 2MP camera for $9.90. The board needs to be programmed with ESP-IDF as explained in details in Github, and there’s no Arduino IDE support. The ESP32-CAM has a very competitive small-size camera module that can operate independently as a minimum system with a footprint of…
Maker Peter Balch has been able to turn an Arduino Nano into an oscilloscope the size of a matchbox. This oscilloscope costs the price of an Arduino Nano (£2 and a display (£3) plus a few pence for resistors. The simplest version of this device, which he calls the ArdOsc, displays data on a computer…
The PiPod is an open source portable music player based on the $5 Raspberry Pi Zero. It uses this affordable single-board computer to run Linux-based software including VLC (which handles media playback) and a custom user interface to display song titles, artist names, and album titles, song length, and other details. A 2.2″ TFT displays…
The NanoPi M4 is designed for applications including machine learning, AI, deep learning, robots, industrial control, industrial cameras, advertisement machines, game machines, and blockchain. Like FriendlyElec’s other Linux-friendly NanoPi and NanoPC boards, the board ships with open specifications. The new NanoPi M4 features a Raspberry Pi-like 85 x 56mm footprint and a low $75 price…
The $20, 802.3af-compliant Raspberry Pi PoE HAT allows delivery of up to 15W over the Raspberry Pi 3 B+’s USB-based GbE port without reducing the port’s up to 300Mbps bandwidth. Power over Ethernet is a widely adopted standard that places power on the Ethernet cable along with the data. It has no effect on the…
While making a clock isn’t an uncommon hacker pursuit, this Arduino-controlled device uses a series of wires to both power and support the clock’s four digits from a bent brass frame. This gives it a decidedly web-like appearance, so much so that Andy Pugh – the maker – notes it’s reminiscent of the cobweb writing…
The maker Edzelf recently open sourced his affordable LoRa gateway on Github. He combined a low-cost Orange Pi Zero with Rak wireless RAK831 concentrator module kit via a custom cable, and a power supply board, all assembled into a metal case. For his project he spent less than $160. RAK831 communicates with Orange Pi Zero over an…
The BASIC Engine is a very low-cost single-board home computer with advanced 2D color graphics and sound capabilities, roughly comparable to late-1980s or early-1990s computers and video game consoles. It can be built at home without special skills or tools and using readily available components for under 10 Euros in parts, or mass-produced for even…
Cultural probes aim to elicit unique responses by asking people to respond to a question, many times in the form of a photograph. The most basic type in this series of cameras is known as the TaskCam, which features a 3D-printed frame and an Arduino Uno at its core. A shield with several snap-off sections provides user interface,…
