After having made a design, you want to test it. And run it. And make software for it. In my case, the software will mainly be written for Linux and DOS with Mocka and with Tcl/Tk. With makes porting it to the other system rather easy.

In many an occasion, I have a PCB made. In fact: I may have several PCB's made. And on this page I offer these extra PCB's for sale to the worldwide population. I will not overcharge. And I don't want to undercharge either. Therefore I present a full list of parts (Bill of material) in each project file. My 'profit' is in the engineering charges. The shipping charges are need to get the things to your part of the world.

PIC programmers

Board options
Everybody is talking about the PIC programmers made by Jens Madsen en Feng San. As soon as you decide it's this programmer you would like to use, you end up with a surprise: you will have to make the PCB yourself.

Not anymore. I have made a batch of PCB's according to the Feng San (RCD) and Madsen (JDM) specifications. These are bare boards. Elsewhere on this site you can find more details about populating the boards. You need dedicated software, like PonyProg, to run the programmers.

Pricetag: JDM board = € 6, RCD board = € 6, Combo board (RCD plus JDM) = € 10

picoSam 32

PCB population options
The picoSam 32 is a slow oscilloscope or a fast data logger, to be run off the parallel printer port. It was made for the serious programmer. I supply the hardware, examples of the programming algorithms and you do the porting to your language (and operating system) of choice.

Pricetag: board = €10, kit = €20, assembled = €30.

Okapi 3

PCB population options
Okapi is the optically koupled AVR programmer interface. But you can use it with other microcontroller families, as long as they are programmed serially and in circuit, where you need no more than 2 outgoing and 1 incoming signal.

Okapi 3 comes on a fully populated first class printed circuit board, mounted to a plywood base. This gives it a firm stand and the chance of accidental short circuits (due to metal scraps laying around on your desk) is minimized.
Okapi 3 is not only a programmer. It is also a snooper device. All programming signals are monitored via LED's so that you can see what's going on in real time. So if you are developing your own AVR programmer software, you need an Okapi 3!

Pricetag : €10 for the PCB, €20 for the parts kit, €30 for the fully assembled version.

Poes is the 'Power over Ethernet System' adaptor. It can be used with UTP cables in 10/100 Mbps networks for carrying one extra signal (or Power/Ground) over the unused pairs of the CAT5 cable. POES comes as a set of two populated PCB's.

Other companies refer to similar products as PoE injectors. Most of them demand the power to be delivered through a 2.1 mm barrel connector.

PoES Competition
  1. cut the power cable in two
  2. prepare the four ends
  3. insert the four ends in the Springcon connectors
  1. cut the power cable in two
  2. prepare the four ends
  3. solder a 2.1 mm barrel connector on each end
  4. insert the barrel connectors in the sockets

With POES the third step becomes very fast and simple. For the competition this is the most time consuming step: soldering a barrel connector to each end. Count on 5 minutes per connector.
Not for POES: just insert the stripped wire ends in the POES connector, close the clamps and you're online!

Parilux 1a

This is a feedback device for programmers, but it is also a simple yet affordable and flexible I/O system. It features seven buffered outputs, four LED's, three open collector outputs, six protected binary inputs, two level presence detect circuitry, on board adjustable power supply.

Pricetag : €22 per unit


Serilux is a very simple feedback device for programmers. One bicolour LED is connected between two pins of the serial port. The art is to make the LED cycle through Red, Green, Off.

Pricetag : €5 per unit


GBexx is a buffer board with a dual purpose: as an extender board for getting the signals out of the Gameboy and, in the mean time, buffering the most important signals. The board is errorfree. But I never tested it with a live add-on. So the direction of the databus buffers may be faulty.
Pricetag : €1 per unit

Parino 4

PCB population options
This is a design from 1993. We sold many units over the years and the first one has yet to be returned. So the design must have been good. Features: 12 relay outputs, fully buffered interface, 5 optically coupled inputs, on board power regulator, two channel serial bus outputs.

Pricetag : €75 per assembled unit. €10 for a bare PCB. €40 for a parinocard without the relais installed. Use the button on the right for quick payment.
