Naw, no need to be like that. There's some impressive (and exceptionally creative!) talent here and I'm looking forward to this being a long, fascinating and
aspirational thread. I suddenly want to spend the next half of my life shopping for power and hand tools and a place to put it all.
I have a great love for thereIfixedit stuff like your phone answerer. That was very cool and reminded me of the handiwork I put in maybe forty years ago making a charging dock for an Icom 2m radio. Radio Shlock blue plastic project box, lots of cutting, nibbling and filing, a few pieces of circuit board to fashion the slot, glued into place, a roller leaf switch for activation, small transformer power supply and a constant-current design charging circuit from the pages of Radio Electronics magazine, no printed circuits anywhere, back in the day when our boffins were still trying to figure out the best TLC approach to NiCad batteries.
Running a guest house has been teaching me a lot about fixing shit, patching stuff, making shit work, fixing other folks' repairs, etc. Especially when it's in a foreign country where the culture is for someone (Korean) who doesn't know how to help to say it just can't be done. So I'm on my own here. Fukkity. And I'm in a place where people think
oh I don't have a 55W FPL so I'll just put this 36W in there or
I don't have a 55Wx2 ballast handy so I'll just use a couple of these 36s I brought. Or, better yet, a couple of weeks ago, I found our real estate guy, who is a retired engineer, decided
replacing ballasts is for the birds and put in LED retrofits. Yay, except they were around 10cm too long so he cut the housings short and drilled holes through the circuit boards to accommodate the stud between the lamps that holds the fixture's glass. FFS. Oh, did I mention that stud happens to be a ground point?
So anyway... I'm running a villa here in Seoul. It's a five-story, seven-unit building with apartments that are mostly 100-139m² indoor space plus large balconies. The first floor is an open parking deck and an entrance lobby. The parking gets abused by the whole neighborhood (it's a Korean thing) if we don't have access controls so we were forced to install a parking bar. Which is OK except because we're cheap cork-soakers it doesn't have an intercom panel and license plate reader like many of them here do.
The folks staying here are given cheap $15 keychain remotes for the parking bar, which is fine if they're driving their own car, or a rental or whatever. And as long as they don't forget to bring it with them. Which is another issue, along with remembering the card keys for the lobby door. And they are instructed that to open the parking bar for visitors, to use the [shitty $15] remote at their window with line of sight to the parking bar. But that shit just goes in one ear and out the other, which means traffic waits while the come downstairs.
So,
solutionz...
Some stuff is easy and very satisfying but hardly pic-worthy, like adding WiFi -enabled controls to our parking bar and lobby door so we can do things like say
hey Siri raise the parking bar and
hey Siri open the lobby door for dumbasses who forget or lose a remote or RFID card. Which beats hiding buttons and cards. Which I've seen a few cases of people (usually delivery folks) actually looking for! Easy to do if you can work a voltmeter without electrocuting yourself. Which with 220V is always a concern. Which I've found out the hard way a few times. And which the Samsung washing machine repair guy found out just two days ago while I was watching him, LOL...
Next WiFi item will be current-draw monitoring at the basement washing/dryer set to automatically turn off the dehumidier. Because pulling wire and installing a new junction box down there is gonna cost a grand.
Now for the
slightly more picture-worthy bit. We wanted pushbuttons inside the apartments to reliably and easily open the parking bar. But, options to upgrade the intercom system or pull new wires would be expensive. BUT WAIT... the whole building is wired for telephones that almost NOBODY USES. Like seriously we're the only ones with a POTS line here. Even our elevator's emergency call feature is on 4G. So I decided to use those phone lines to carry the pushbutton open/close from the apartments down to the lobby deck where the telco demarcs are. OK, great. Except now is where a little thereIfixedit comes in... We don't want to have surface wires showing. Running a hidden cable around the corner of the parking/lobby area from the telco box to the parking bar is going to be expensive. So, what to do...
First I made some push buttons to plug into the wall jacks. I made eight of these (all apartments plus one for the office). Effort was taken to find water-proof low-profile buttons and unobtrusive housings. I don't have a workshop here, or a drill press, or a good selection of bits, the coffee table and an old shelf is my bench. A small pilot hole and then a Japanese step bit does the work on this piece. The last one or two size gradiations for the button's hole are done by turning the part on the bit, LOL. That helps me use body english to keep the step bit on-target and avoid bloody fingers.
No, I didn't leave the strain relief like that. That was a failed hot glue experiment. I would up just tying a tight knot in the phone cable.
Button installed on a kitchen backsplash. Some have the buttons velcro'd to the WiFi routers instead. Just different patching in the punch-down block in the apartment.
And now for the wireless magic downstairs (LOL):
There are four telco pairs going up to each apartment so I settled on using the second pair for the parking bar pushbuttons, just because. So there's the orange/white pair joining them all up semi-artfully through the 1st floor punch-down block (that's the demarc on the left) and then going through a molex quick-disconnect (if troubleshooting required), then soldered to a button connection in the remote.
Oh, and the remote is hung off a hook that way because if I velcro it to the back of the box it won't work. Probably standing waves or some undesired grounding effect from being too close to the metal behind.
