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

Can't remember right now how TV power supplies without the third PE conductor are arranged (double insulated). I've worked on quite a few of them over the years, but can't recall the arrangement of...

Yeah, I'm not gonna mess around (too much) with the electrical wiring in my home/shop. I was mostly interested in how to design a proper power supply that's safe to install on lab equipment which...

Re: Line filter question

Well, I haven't done anything yet, hence this discussion :D


Yes, my apartment is in a pretty old building, but there are no pipes close to my workbench anyway, so it's not an option.

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...

Re: Line filter question

I'm mostly interested in protecting the stuff I work on if it gets connected to this power supply or if it powers a soldering iron. I haven't had any mishaps with the first supply I built using a DPS...

Re: Line filter question

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...

Re: Line filter question

I know what it does, I was just curious how such a setup would behave when the earth pin (PE) is floating. It's not just my apartment - I could carry this supply someplace else and I may face the...

Re: Using car key fob as generic remote control

There isn't anything else on the PCB, as you can see in the pic I showed (the other side only has the battery), hence why I think the PCF chip in the fob handles the immobilizer too...

Ok, good to know - that's why I said "inferred" :D. What threw me off is the antenna coil in the datasheet for the PCF chip, connected to the "IN" pins on the left - apparently those receive...

Red face Re: Using car key fob as generic remote control

After doing some more reading, I learned (or rather inferred) some more about this particular PCF (https://pdf1.alldatasheet.com/datasheet-pdf/view/1132654/PHILIPS/PCF7946AT.html) chip, despite the...

Good day folks. It's been a while since I've DIY-d anything, so the other day I was thinking if it's possible to use the key fob of my car as a remote for other automation stuff. I have quite a few...
