Connect up to 32 Relays to Raspberry Pi with a Stackable 4-Relay Board (Crowdfunding)

People have been playing with off-the-shelf relays on Raspberry Pi boards ever since it was released in 2012, and over the years, some companies have maybe Raspberry Pi-specific relay boards such as Strawberry4Pi and Pi-OT. Two years ago, Sequent Microsystems introduced a stackable 8-Relay board enabling up to 64 relays to be connected to a single Raspberry Pi board. The 8-relay board only supported 24V/2.5A, and the company is now back on Kickstarter with a 4-relay board with 250V/10A line-switching relays that can offer up to 32 relays by stacking 8 boards connected to one Raspberry Pi board via the 40-pin I/O header. The board comes with four Songle 250V/10A relays, 3-pin pluggable connectors that accept 18 to 22 AWG wires, and a 5V/3A power supply is recommended. If you stack multiple relay board a beefier power supply may be required. Here are some power consumption numbers provided by the […]

Bangle.js is an Hackable, Open Source JavaScript and TensorFlow-driven Smartwatch (Crowdfunding)

Espruino brought JavasScript to the Microcontroller, now Bangle.js is bringing Javascript plus TensorFlow Lite to your smartwatch. There has been some movement by some developers that says that JavaScript should be used for everything, even though I find that idea ridiculous, I still find JavaScript a fascinating language. The NeaForm Research team and Gordon Williams (the brain behind Espruino) have all teamed up in launching Bangle.js Smartwatch. Bangle.js isn’t your ordinary smartwatch, at the heart of it is the open-source ecosystem. JavaScript plus TensorFlow Lite and of course, a cool looking Smartwatch is what Bangle.js is offering. Bangle.js was launched at the recently concluded NodeConf EU conference, and the goal is to bootstrap an Open Health Platform hopefully. NodeWatch is the specific implementation of Bangle.js for NodeConf EU 2019, co-developed by Espruino and NearForm Research. This project has the potential to bootstrap a community-driven open health platform where anyone can […]
