Radio flea market Bladel 2025
Today I went to the radio flea market in Bladel. Just like last year, I found some good stuff. Only this time, the location wasn’t the best. Parking was difficult. The radio market was divided into lots of small rooms. I’m not sure if I saw everything.
My purchases:
- 2 DC Motors with gearbox
- Atrix MPM-1010 Power Meter
- Chroma 66202 Power Meter (I had already bought the Atrix when I came across the much better Chroma)
- 5 LED panels and 1 panel for spare parts.

Mains Power Measurement Adapter
Recently I bought a power meter at the Bladel radio flea market. To make it easier to use this power meter I needed a measurement adapter. I could buy this, but it is more fun to build one.
I made this schematic to connect everything. The resistor on the schematic is internal in the power meter. The switch is to place the voltage measurement before or after the current shunt. This is done because the voltage measurement draws power.
For a high power DUT (Device Under Test) you want the voltage measurement on the DUT side because there is a voltage drop across the shunt.
For a low power DUT you want to have the voltage measurement on the mains side to prevent the power from the voltage measurement being added to the result.
This small circuit I build in a remote controlled socket enclosure.
Finished it looks like this: (I know I still need to replace the banana plugs by a safety model, they are on order).
Installed on the safety transformer:
