The Raspberry Pi and other low-cost, board-based computers are becoming increasingly popular amongst developers and hobbyists, thanks to the Internet of Things revolution. Users are easily able to experiment with IoT projects by connecting to a network using wired or wireless connections – whether this is through the simple use of an Ethernet cable, or with complementary accessories such as the Raspberry Pi’s Wi-Fi adapter dongle.   However, users requiring access to internet d ...
I am hoping that a new HAT we have designed and released will be of interest to anyone wanting to control motors within their own projects using the Raspberry Pi computer. The Pulse Train Hat is an add-on board for the Rapsberry Pi computer and allows clean, fast and accurate pulses to be created using simple ASCII commands.   There are many hardware designs where a variable frequency pulse is needed, but one that is the most popular is for driving stepper/servo motors that use pulse an ...
Hi, my name is Dan and my ham radio callsign is M0WUT. I am developing an automated Raspberry Pi Zero based transceiver for the WSPR amateur mode. What is WSPR? WSPR stands for Weak Signal Propogation Reporter (full details WSJT Home Page) developed by Joe Taylor, K1JT. In short, amateur stations transmit data packets containing their callsign, their location and how much power they are transmitting with. Once received, these can be decoded by a computer who uploads them to a central databas ...
If you are here to see how to add Ethernet / soundcard functionality to the Pi Zero, this is a part to be used in my automated amateur radio WSPR transceiver. Explanation of which can be found here: WSPRpi part 0: Introduction and what is WSPR? If you are not interested in how I intend to use it and just want to see how to add Ethernet or a soundcard to a Pi Zero, skip to the Design section.   Finished result   WSPRpi For people interested in the use in the WSPRpi project: The tw ...
