Re: Using car key fob as generic remote control
Again, it's not about using the car as a receiver, since it's too far from anything (I live in in an apartment complex, so it's down in the parking lot) - it's about using the car's fob as a remote...

Re: Using car key fob as generic remote control
Ok, I just had a go with these RXB6 modules and I get absolutely nothing out of them. The program the chap shows in his article (https://alex-hhh.github.io/2018/05/arduino-433mhz-receiver.html)...

Re: Soldering station thoughts and guidelines
Indeed, that's what Louis Rossmann uses, at least in the early days, so I tried finding one too, but I cannot seem to find anything Hakko here unfortunately. There are only a couple of listings and...

Re: Soldering station thoughts and guidelines
I just measured the edge of my smallest T12 tip and it's 2mm, so even the smallest knife tip from that original JBC lineup doesn't cut it (pun intended). They cost a fortune for a friggin' iron tip...

Re: Soldering station thoughts and guidelines
No - the T12 handle came with the "Ksger" base station from Aliexpress.
The C210 ones I linked to on Aliexpress are the JBC clones, I reckon. I'd get a complete station instead of trying to adapt...

Re: Dell 2700w j728n 3kVa UPS not starting
One way of simulating UPS packs I thought of at one point, though this is both dangerous and possibly expensive if you don't have one, is to use a variac with a bridge rectifier. Of course, you...

Re: Line filter question
I did some tests today: I took a power transformer that outputs 24VAC, enough to power my soldering iron through a bridge rectifier and DC-DC converter to limit it to 24v and measured ACV between the...

Re: Line filter question
There aren't any pipes that are easy to run wires to anyway, hence why I suggested I should just use the TN-C method in each outlet. The only danger I see with this is if someone, for some reason...

I can't do that in this case, since the caps are inside the metal shell and I DO want a connection to earth just in case there IS one there. I think I can use an IEC connector and just omit those...
