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.
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.
