DACS Data Acquisition & Control System -- This module is a serial data acquisition and control system that provides four 12-bit analog inputs, four relay driver outputs, six general purpose logic inputs and temperature. Simple serial commands can be used to acquire data to scripts using your Beaglebone or Raspberry Pi.

DECA Decade Divider Module -- This module takes a 10 MHz clock from a source such as a rubidium reference and divides it down in decade increments to 1 millihertz (0.001 Hertz). Available outputs include 5 MHz and a buffered version of the 10 MHz input. This project supersedes the DECUS and DECL projects.

DSYS Serial to DDS Controller -- This module controls one or two inexpensive DDS modules using serial port commands. The first DDS module mounts above the DSYS system board, making a compact unit for embedding in a project.

FEBO Interface for FE-5680A Rubidium Reference -- This board plugs directly into the DB-9 on the FE-5680A to provide regulated power to the unit and access to the RS-232 pins. It also provides logic buffering of the FE-5680A output and an output for an LED lock indicator. A FEBO variant, FEBO-PLL, also provides a jumper selectable PLL-multiplied output.

MIDE Programmer and Interactive Tether -- MIDE stands for "MyForth IDE." This is a tongue in cheek reference to our minimalist "IDE." MyForth development uses a specially-programmed 850 chip to download programs into chips that have a C2 interface. This programmer is described in the PROG project.

The MIDE application builds upon the PROG programmer to additionally implement a "one-wire" tether. This tether uses the same bi-directional C2 data line used for programming and does not require allocating any extra chip pins. You can go from programming a chip to tethered debugging without switching any connections.

With the one-wire tether, all myforth definitions (other than macros) can be executed interactively. Words can be exercised with input parameters. Output results can be displayed with dump and stack displays. The one-wire tether is particularly useful for exercising applications that use the serial port, which may make it unavailable for debugging.

An added benefit to using the one-wire tether is that interactively executed words do not need to be visible in the standalone interpreter's dictionary, thus avoiding the need for dictionary entries for debug words. Finally, for applications not using the serial port, debugging does not require compilation of the standalone interpreter and allocation of the serial port pins.

PRUBY PLL Multiplier for Rubidium References

RF Amplifier Board

YACC Crystal Calibrator Modules -- This is Yet Another Crystal Calibrator for older HAM radios. It is microprocessor-based but fits into many calibrator sockets on older receivers (schematics for popular receivers are included).
