CompuPhase articles and Application notes CompuPhase

On-line publications “for programmers”; they are also written “by programmers”.

CompuPhase develops electronic designs, printed circuit boards, prototypes of custom apparatus and the embedded software that runs on the devices.

Examples of such apparatus are the various LED-panels that we set up in several exhibit centres, under contract of Podium (Netherlands). Embedded systems

CompuPhase Services include contract programming of applications and embedded systems, and also the design and production of custom electronics.

This site uses hands-on experiments to show the basics of how real things in the real world are controlled with computers.

Controlling The Real World With Computers

This site is also for anyone who is the least bit curious about monitoring and controlling such things as motors, lights and switches, or recording and playing everything from sound to the arm position on a robot.

Experiment 7 – Bi-directional Control Of Motors And The H-Bridge

It would be useful to be able to run a motor in either direction. That’s simple with a motor of the type that’s been used in the experiments thus far. Reverse the DC power connections on such a motor and its shaft will rotate in the opposite direction. One way to control direction is to use switches arranged in the following manner:

Bug Labs – Modular Stackable Embedded Computer

BUGbase is a fully programmable computer, with a CPU, RAM, rechargeable lithium-ion battery, USB, Ethernet, micro-SD and serial interfaces, and a small LCD with button controls.

Bug Labs - Modular Stackable Embedded Computer

BUGbee is a low-power radio module based on the 802.15.4 protocol, perfect for creating a personal area network (PAN) for machine-to-machine (M2M), home automation and intelligent grid applications.

BUGvonHippel is a breakout module to which you can connect sensors, wires, and USB devices. This module is named after Dr. Eric von Hippel of MIT who wrote the book Democratizing Innovation.

VeeCAD takes a schematic generated netlist and assists you to build a layout – but on stripboard (Veroboard). The usual design tools are provided: netlist import, component footprint definition, component positioning, wiring and connectivity check.

VeeCAD for Stripboard with Auto Router

Engineers and hobbyists use VeeCAD for prototypes and small quantity builds, saving hours planning layouts on graph paper.
