I have been contacted by a number of people in search and rescue (SAR) who are interested in the other Ripple LoRa mesh projects I have been working on, and it got me to thinking about making a dedicated device for the field personnel.This device doesn’t require a companion Android handset, as it has a very simple UI for the user. It has a small OLED screen and just 3 push buttons, so only offers limited types of interaction with the user.

By supporting concurrent communication over Bluetooth Low Energy (BLE) and Sub-1GHz wireless, the STMicroelectronics STEVAL-FKI001V1 dual-radio development kit gives unrivaled flexibility to envision, build and connect IoT devices like smart sensors, finders and trackers which can be configured, updated, remotely monitored and tracked using various network topologies, protocols and services. The Kit integrates two radios,…
Just over a year ago we have introduced our first Arduino-like 32-bit board, called Fishino32 which was characterized by the format of the widespread Arduino UNO (but also of the Fishino UNO), although equipped with a 32-bit microcontroller capable of exceptional performances, when compared to the average prototyping board of its kind. We have…
[youtube id=”5H85RDA5HEw” width=”620″ height=”360″] Today we present a mod of Dotklok, the product that we presented few months ago , with new features such as reading ambient temperature and controlling display brightness based on the ambient light. The whole thing can be controlled remotely via a standard TV remote control. Open firmware and hardware have…
Sometimes you want your creation to look great. That was the case here, as this electromechanical clock integrates several different types of metal along with a chain drive into something that’s as much a work of art as it is a practical timekeeping tool. This clock was designed, machined and assembled, every piece from scratch…
An audio file player based on an MP3 module with FM radio, Bluetooth and remote control; a 10 V stereo output and two speakers are used for the listening. The device can even work via outlet or using two 3.7 V rechargeable lithium batteries. We all know we can find any kind of loudspeakers…
