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:

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.


The panels:

The inverter:

Surge-arrester, new 3 phase group and an energy meter:

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.

Dead Battery

One of the Batteries from my Bosch cordless drill machine had died. I could buy a new one but that is rather expensive. So I opted to take the batteries out and put a cable on it. The cable plugs into my 12V power supply that powers my lights etc.

The cells inside (5 cells at 0V):

I have mounted a cable gland in the plastic enclosure from the old battery so I have a strain releave for the cable.

Plugged in the drill:

I added a diode to the power supply to protect my power supply against voltage spikes from the motor.

The downside of this is of course that I have a cable connected to it now. But I still have 1 battery that functions so I can still work wireless :p. But if I’m working at the workbench and the battery is flat, then I can use the cable to avoid waiting for the charger. Another downside is that my LED lights dim as I start the drill, this is because it draws too much current. The power of the drill isn’t as big as on the battery. My power supply delivers 12V while the battery does 14.4V.

Updating my network

I was using my network more intensely to transfer files the last weeks. And I got tired of waiting, so it was time to update my network. So I ordered a new switch and router from, and today they arrived :).

My old “fast ethernet” 100Mbit/s equipment:

Linsys WR454GL 4 port router
D-Link DES-1005D 5 port switch

My new “Gigabit” 1000Mbit/s equipment:

Linsys E2000 4 port router

Cisco SD2005-G2 5 port switch

The new gear is working great, the only downside is that you need to install a config program on the pc to config the router. It has a build in web interface, but it doesn’t cover all the settings :s.
