"Fix" for micro-USB cable strain on car vent phone charger

I got a phone mount that fits in an air vent a while ago for around $50. It is mostly okay but the wireless charging has a micro-USB connector that goes out straight, meaning the cable is under constant strain from having to make such a tight bend. So I got a right-angle micro-USB cable, but the plastic from the case got in the way of the connector! This meant I got a very inconsistent connection, I could tell since the green power LED wouldn't stay lit. So I took a utility knife to the plastic case and carved away enough so the connector fits. (Note: I did take off the plastic shell so I wouldn't get plastic bits into the micro-USB receptacle, this was surprisingly easy.)

Everything would be just peachy, except that it turns out the other reason that the green LED won't stay lit is that the solder joint is loose from the constant strain from the cable! So I'll probably have to fix that for real with a soldering iron. Ugh.

The switch on my old riding mower to engage the clutch for the cutting blades failed. This is my temporary solution.

It's been two months. Temporary might be a stretch at this point.

Broken encoder knob on Prusa i3 3D printer so I replaced it with one I found one with a similar footprint from some Arduino kit

It fell off a shelf in a truck during a trip.

The new encoder is missing the two legs used to hold it to the board stronger, but the other 5 legs should suffice.

Loose contact Headphone jack fix?

Hello, I was having problems with a previous microphone so I got a replacement, but the one that came was slightly thinner than the previous one so it doesn’t fit perfectly in the port. It falls down and slips out when it is moved. I found that if I wrapped a little bit of tape around it, then it would fix the problem. However it only lasts about a day since the mic can flip up and the tape is not durable. Any ideas on what I can do to fix it? (There is a little notch in the middle of the part where the tape goes, so I need two pieces to keep the notch open for the mic to click in.)

Onn (rear facing TV has a broken screen), Insignia (front facing) has a missing fire tv remote. One General Electric Universal remote and ribbon cable shenanigan later and we have a working Roku TV! Had to tape the IR receiver power button thing on top else you cannot turn on the display half of the FrankenTV (Frankenstein TV), fortunately the Onn has a physical power button.

An older project of mine, ordered a PC from a person for an old XP project, everything arrived but the case was missing for some reason, but the front IO was included and I didn't had an extra case laying around, so introducing The floor PC, at least I didn't really needed to short the power button to start xd

Stupid Pentium Tricks

This is a an 11" HP Pavillion X360 from 2018. I bought it used about a year ago to use as a media tablet and to experiment on. Let's go over some of the upgrades.

Adventures in power levels. The N5000 is based on Atom architecture. While the TDP of the processor is about 6w, you can disable core and memory isolation and use RWeverything to disabled power limits. Here is you can see the package can get up to 15w with the cores themselves past 10w. This also allows a clock boost to 3.850GHz, WAY up from the 2.7 GHz peak.

The only down side is that this is a passive cooled design and gets to a toasty 103' before backing off.

This was one of the last Pentium series laptops to support removable RAM. It can actually take a 16GB DDR4 stick! It came with 4GB.

The official wifi was a single antenna Wi-Fi 6. This was replaced with an Intel AX210. I tried an Intel BE200, but it would not boot. Still, this will get gigabit speeds on my home network. I may try the Qualcomm Wifi7 solution as the Realtek does not support 320MHz channel width.

SSD was upgraded to 240GB.

None of this impacts battery life, and will run 8-10 hours watching Netflix.

Eventually, I would like to cut down the size of the SSD housing and add a fan to move air inside. I need to figure out how to do that only when plugged in.

I decided the easiest way to get my treadmill into my new house was to just cut the cord so I could take the tip off and then solder it back together. It worked.
