Blue IR: Build your own universal remote

Sarunas built this device to replace a bunch of different remote controls with a smart phone:

Blue IR

Build your own universal remote

Features include:

Control TV, HiFi and more from Android, iPhone or Windows Phone.
Control devices using NEC, RC5 and SIRC protocols
Provides Bluetooth Low Energy service for controlling it from other devices.

A solar version was also designed to avoid having to change the battery:

Blue IR solar version

Despite that Bluetooth Low Energy device uses so little of it, the battery will eventually run out. To overcome that, the old device was improved by adding a solar charger.

Open Source AIS Transponder

November 27, 2016November 23, 2016 fustiniAIS, EAGLE, gps, RF, Transponder, wireless3 Comments

Automatic identification system (AIS) is an automatic tracking system used on ships. Peter Antypas designed a low-power AIS transponder:

Open Source AIS Transponder (Class B)

This is the first ever (that I’m aware of) attempt at creating an open source AIS transponder

Hardware:

On the hardware side, the design is based on two Silicon Labs 4463 transceiver ICs and an STM32F302CBT6 ARM Cortex M4 microcontroller. One of the SiLabs ICs acts as a transceiver, while the other IC works as a receiver only. In receiver mode, each IC tunes to a different channel. When a transmission is scheduled, the ICs swap channels if the transceiver is not listening on the next transmit channel. This configuration may be construed as a violation of the AIS specification, but it makes for a much simpler PCB layout and negates the need for a 3-position RF switch.

Software:

There are two programs that need to be installed on the flash. The bootloader and the main application.

HydraESP32: HydraBus and ESP-32S

The Espressif ESP32 features a 32-bit 240 MHz dual core processor with Wi-Fi and BLE. HydraBus created this shield for ESP-WROOM-32 or ESP-32S.

HydraESP32 v1.1 Rev1 with ESP-32S is alive

This shield can be used with or without HydraBus board, you can even cut HydraBus specific right side (on the line) to have a tiny ESP-WROOM-32 breakout board.

Put That Amateur Radio License to Use on 915 MHz

November 11, 2016November 11, 2016 fustiniHAM, RF, wirelessLeave a comment

Amateur radio enthusiasts in the US will be interested in Faraday, an open-source digital radio that runs on 915 MHz, which amateur radio enthusiasts may know better as the 33 cm band. You can transmit on 915 MHz without a license (in the US), taking advantage of the Industrial, Scientific, and Medical (ISM) exemption.
