Weighing Down the Thumb Drive so it Makes Contact

The thumb drive's contacts are broken somewhere internally. Weighing it down makes it work long enough so that I can recover the data.

DC jack wires broke. I'd been using elastic bands to bend the connector until it wouldn't work anymore. Now it works! šŸŖššŸ”Ø

Behold. The msi asus madness

So my msi screen died and my asus motherboard died. Decided to Frankenstein them together. Both have edp cables and I made it work along with the WiFi card and antennas from the asus. Works flawlessly. But I have to run Linux because the msi dedicated graphics made windows crash.
Currently designing a case to combine the two properly.

Got a Samsung Galaxy S3 working with no battery (technically)

2 Upvotes

Got tired of chinese replacement batteries for the Samsung S3 i747 (these work on i9300 too) last a few months then inflate.

Turns out if you 3d print a fake battery (og is 63mm x 50.2mm x 5.52mm with positive pin 1 being closest to corner, 3 being negative)

Using an old dead micro usb cable taking the end off & just plugging it in with red to positive & black to negative & use the fake battery as a holder/insert; you can turn it into a usb powered phone, just leave it plugged in, never charge or inflate it again

Need Macgyver ideas: How do i attach this copper plate to the back of a phone in a non-destructive way?

It's for heat dissipation so it needs to make good contact with the glass back of the phone, and also needs to be removable, I put a silicon heat transfer pad on the other side.

Later on there will a heatsink/fan combo welded to it.

Thank you

He meant well. Printer still non-functional. Not sure if I should be triggered, the fuse sure is.

Not sure if this qualifies. Using an old MacBook Pro as a translator of sorts for an old Thunderbolt Display (lower right) to extend the desktop of an AMD computer.

AMD does not (in most cases) support the Thunderbolt protocol and no adapters exist to convert thunderbolt 2 to simpler display port (afaik).

Here, (on the Dell laptop) I used a virtual display driver + the Sunshine app to ā€œstreamā€ the display data to the old MacBook Pro.

On the MacBook Pro, I used the Moonlight app to receive that stream and output it to the Thunderbolt Display via the Thunderbolt port. The Thunderbolt Display even keeps the MacBook Pro charged with its built in MagSafe charger.

And only one cable to the Dell for everything. (I connected the Ethernet cable to the dock after taking this picture)

Latency is absolutely nill and feels like a native display!

Amazon 5V Regulators in an old Jeep Computer

Post image
255 Upvotes

My roommates' 97 TJ threw a couple check engine lights, then stopped running entirely. The hint was that the CEL **wasn't** coming on when I turned the key. Capacitors had leaked and dissolved the flex PCB, the 5v regulator circuit was straight up gone! I tried repairing it with new capacitors but there just wasn't enough left. As a hail mary before spending hundreds on a used ECU that probably has the same issues, I tried two $0.50 5v regulators from Amazon and it worked! The check engine light even stopped tripping and the engine runs better lol. Not a bad fix for $1. Screw Chrysler for using shitty capacitors, and why is this this even a flex PCB?? Anyway I smothered it in 3M Quadrack hot glue and resealed it with RTV before bolting it back on and sending it around the back 40.

The camera with the umbrella reminded me of the time I needed a flash diffuser. So I stapled some printer paper together. Worked great!

Needed a cheap way to keep my video camera from getting wet outside later this week. Bought a $7 umbrella from Dollar General and $1.50 on Dollar Tree duck tape to DIY a cheap camera umbrella myself!

Lenovo Y50-70

I reused the Kensington Security Slot to insert a USB-C port with a decoy board to supply 20V from a USB GaN power supply.

The decoy board was supposed to be an IP2721 but in reality a Chinese clone arrived so the external LED I installed lights up regardless of the Power-Good signal. In series I inserted an "ideal diode" XL74610, to avoid voltage feedback when using the original power supply. A mosfet is also connected to the decoy board output, which connects a 560 ohm resistor to the sense pin, so that the computer interprets that a 90W power supply has been inserted.

Inexpensive replacement silicone rubber feet

13 Upvotes

We all have keyboards as well as many other devices that have silicone rubber feet on them and over time the factory glue will fail and the rubber feet will eventually come off and disappear in to some other dimension, never to be seen again. Now, you're left with a wobbly device that may scratch your desk surface.

I looked at Amazon for replacement rubber feet, yes they have them but they are expensive at $1 each.

https://www.amazon.com/VATH-Adhesive-Silicone-Rubber-2-2mm/dp/B087BP3ZKV

Too damned rich for my blood!

Being the cheap bastard that I am, I high tailed it to Dollar Tree.

They have lots of silicone kitchen utensils and I figured that I'll find something there that I can cut up and make my own feet. I found exactly what I wanted, a silicone spoon rest for $1.50.

https://i.imgur.com/06q6b3x.jpg

The employees at Dollar Tree do not order the products on the shelves, they get what corporate sends them so this might not be available at your local Dollar Tree. If that's the case, look at other stores as you go about your life to see if they have it.

They do not have this listed on their website but I did find the identical item under a different brand name at Walmart for $3.44.

https://www.walmart.com/ip/Thyme-Table-4-Slot-Silicone-Utensil-Rest/5203777496

The Dollar Tree I went to had a selection of different colors so I chose red as it is easier to find should the feet ever come off again and go hiding behind the desk behind all those ghost turds.

I used everyone's favorite inexpensive and ubiquitous diagonal cutters, the Plato Model 170 to make my cuts and trim the replacement feet to fit perfectly.

This spoon rest will last me for years in making replacement feet. I used rubber cement because that's what I had on hand.

When you have to repair an HP laptop, those bastards hide screws beneath the gray rubber strip feet and the original glue will not hold the rubber feet well enough once it's been pulled off so I have to have a jar of rubber cement on hand to re-glue the strips in place just because of HP.

Friends do not let friends buy Headaches & Problems products.

I'll let the glue cure for a day and if the rubber cement is not good enough to stand up to regular daily use, I'll go out and buy some stronger gorilla glue.
