Beric Dunn, K6BEZ, designed a handy antenna analyzer prototyped on a HamStack DEV board and ported to an embedded PIC and another version on an Arduino.
Presented at Pacificon 2013.
John, KJ6K, is designing an open source keyer project written in Microchip C18 C language compiler for the HamStack. The video shows some basics of the multi-tasking capability of the HamStack software stack.
These projects are all built with the HamStack microcontroller platform. Some projects are built entirely from off-the-shelf HamStack kits, some have additional customized hardware. If you build an interesting project, we would like to show it off here.
This mini-project shows how to use a mechanical rotary quadrature encoder as an input device to indicate left or right knob rotation. The example is written in Swordfish Basic.
Frank, N6YP, developed a great repeater site temperature monitoring system using our GPIO board and digital temperature sensors. The system keeps track of 3 repeaters and displays the status on a 4 line LCD.
This CW/PSK keyboard project is featured in the June 2012 issue of CQ magazine. The HamStack project uses a PS2 keyboard to send CW & PSK to an Elecraft K3 or KX3 radio and provides rig control through the serial port.
Brian, W6BY, demonstrates ham radio homebrew projects at the Maker Faire. Brian is adding HamStack smarts to his microwave station. This YouTube video shows the HamStack CPU, CW Keyboard app and the GPIO board controlled by an iPhone.
Robert, KJ6HFR, shot a very handy video showing how a HamStack can perform high / low voltage detection. Check it out on You Tube. In this example, an interrupt request flag is set when voltage to HamStack board falls below 2.8 volts.
KJ6HFR’s video companion to his HamStack cookbook. Many experiments are done without compiling any code. Instead, the Configuration Editor in the PICkit2 application is used to set chip configurations, such as oscillators and Watch-Dog Timer.
This project uses the 8870 DTMF decoder chip circuit built on a HamStack prototype board. As tones are decoded, the ASCII character is sent to the serial port. The firmware is written in Swordfish Basic.
