New soldering iron
The past few years I did my soldering with a Aoyue 936 and a Velleman vts25, but the Aoyue was underpowered and the Velleman needed a new tip every few months and isn’t temperature controlled.
So it was time to buy a new one. I decided it would be a Weller WS81. There was an action to get it with a free dry cleaning station, so I got that too.
Wire tugged away.

Going green
A few weeks ago we decided to put some solar panels on the roof. We chose for 22 251W bisol pannels, with a Piko 5.5 3phase inverter. Yesterday Elcubi installed it all.

RCD Differential Switch Teardown
With the instalment of the solar panels we tested the RCD differential switch, and it refused to work, so we replaced it.
I have taken a look at what’s inside of it:

Spot welder
I had a lot of 10mF 6V capacitors where I didn’t had a use for. After putting them in a different place again, I decided to create a sort of spot welding machine with them. The inspiration comes from a elektor magazine where something similar is done.
The intention is that the amount of energy that is put in the capacitors is adjustable. Therefore the output power into the short-circuit will be adjustable. This is controlled by a microcontroller. I will also make a measurement on the output pins, so that sending the current to the output can be delayed after contact (to prevent sparks)
For adjusting the settings I have added a display and 3 buttons. For the display I chose an HP HDSP 2111 H5, this display is smaller than an LCD and therefore fits easily on the front panel, a disadvantage is that it can only display 8 characters.
The front panel layout I want to use:
