Breadboard supply.
Several circuit asks for several power. The ones I bought were more or less for 5V/3.3V. I wanted my own sypply with my used supplies. PCB is worked out great. Good quality. Very quick recieves. Compl...
Sinus Generator
Always wanted a nice generator wich creates a fine sinus. Not only for testing circuit, but also to see if my scoop still displays correct. PCB is looking great and very happy. Very quick recieves. Co...
Ordered project
Looking good and still have to investigate.Looking great and really quick delivery. I think the most fast until now.

Voltage indicator
This PCB creates numbers by 2 CD4543, of which the input can be selected with 16 options. (4 dipswitches). Looking great and really quick delivery. I think the most fast until now.
Diode trick/signal feed
This PCB will provide a Diode trick circuit in combination with a signal feed. It was the last missing for a model train control. To combine the use, it will save space in the control cabinet. Very us...
Potentiometer in OPAMPS
In testing several OPAMPS to use as guitar effects, a sum of potentiometers are available to adjust settings.
Relay delay
For my guitar playing I create pedals and coonect them to a seld made amplifier. I wanted a delay for the speakers so, this PCB is created. Looking fine. Very quick recieves. Compliments
S88 connector
In order to connect feedback signals from a modeltrain track, to several modules these connector are made. Looking very good and please with the result. Very quick recieves. Compliments

Supply for 9V device.
A earlier project ijkbooprog needed a 9V supply. I tried a different transformer so, a newer PCB was required. Looking great and really quick delivery. I think the most fast until now.
Opamp tester
A PCB which makes it possible to check/use several OPAMPS. Looking great and really quick delivery. I think the most fast until now.
Tremolo effect
This circuit is created, to achieve a tremolo effect for the guitar.
Calibrate/feedback module.
This circuit seperates by using a PIC and control relais. It devides rails to use as a configuration part.
