DIY/Fix-It Up/Repair / Nexus 5 Repair
« on: March 05, 2017, 01:40:08 PM »
I thought I already posted my first repair. Guess not.

The ribbon cable that connects the display to the motherboard failed abruptly a few nights ago. I had replaced this part around October. Turns out cheap Chinese parts don't last long.

Well I need a phone and couldn't wait a week for replacement parts, so I bought a new phone that night.

Now that there's no rush, I'm going to order the replacement part and fix this again.

In the photo below, the ribbon cable that plugs into the board in the left has failed. The connector was actually getting was because it's making a bad connection.



I'll update when the part arrives.

Hope the dumpsters are kind to you and you find something nice under your Christmas trees.

DIY/Fix-It Up/Repair / Car's gotta pass inspection...
« on: December 10, 2016, 05:09:40 PM »
I brought my car junky old car in for state inspection and it failed. They handed me an estimate for about $750.

The car is 14 years old and worth $1000.

That's not an option.

It needs new front brake pads, rotors, a lower control arm and a tie rod end.

Brakes are easy.

I've never changed out a lower control arm or tie rod before but I watched some videos on how to fix them on my car and it looks pretty straightforward. A few New England winters have made it a little rusty so we'll see.

I bought pads, rotors, control arms and tie rods for both sides - about $225 in parts with shipping. They'll be here in a week. I need to pick up some large sockets and wrenches. I've got a whole can of PB Blaster to cut through that rust, and a MAP gas torch just in case.

Let's see what happens.

Trash Talk / Exploding Dumpsters

The Elizabeth incident unfolded after two men found the backpack in a waste basket on North Broad Street and Julian Place around 8 p.m. Sunday, the mayor said.

The men took the backpack "because they thought it was of some value," walked for a bit, then saw wires and a pipe, dropped the package and notified Elizabeth police, he said.


Later on while a bomb defusing robot was working on it, the backpack went off. Dunno if it was intentional to dispose of it or it went on its own, but scary stuff. Those guys were pretty lucky.

DIY/Fix-It Up/Repair / Game Boy Repair
« on: September 10, 2016, 06:23:10 AM »
I picked up a broken Game Boy pretty cheap. Vertical lines of dead pixels are pretty common with these.



I saw some videos online showing how easy this was to fix. By rubbing a soldering iron over the lower ribbon cable where it meets the LCD, you could reflow the solder and eliminate the vertical lines.

Using my trusty Weller soldering station I found by the curb a few years ago



Success! All the lines are gone.

HOBO Stew / Noodles & Thai peanut sauce
« on: September 05, 2016, 03:46:15 PM »
Here's a cheap recipe that's delicious.

- 1 Ramen noodle package
- 1/2 cup peanut butter
- soy sauce
- garlic powder
- hot sauce
- water
- lime juice (optional)
- crushed peanuts (optional)

Boil up the ramen noodles. Drain and set aside. In same pan, melt peanut butter over medium low heat with soy sauce. Add a pinch of water to thin and help it melt. Let it thicken up and add hot sauce and garlic powder.

Mix with noodles. Add lime juice and crushed peanuts.

Not terribly healthy but cheap and tasty.

The Dung Heap / efray question
« on: August 25, 2016, 10:47:48 PM »
I won an auction for a Super Nintendo supposedly in good condition, functional, etc. I also bought a few games. So far I received two games, and the console itself just arrived today. Hooked it up and tried it. One game is glitchy, second game doesn't even work. All games are supposed to be functional. I should be getting a few more in tomorrow to test.

If none of the games work, I can be confident that the system itself is bad. What's the best way to handle getting it back and a refund. The guy has 100% and I don't want to ruin his feedback.

Metal Heads! / Metal Prices
« on: April 18, 2016, 06:31:20 AM »
I took in a load this weekend. Metal prices have tanked and it was hardly worth the effort. I still have batteries that I'm going to hold on to until prices rebound.

Motors: $0.05 / lb.
Cords: $0.35 / lb.

Motors were paying $0.25 at their peak, and cords were $0.75. Motors alone should have been worth more than what I was paid for everything this weekend. Real bummer.

DIY/Fix-It Up/Repair / Gorilla Tape Repair
« on: March 08, 2016, 06:01:06 PM »
Was in gf's car at the walbart getting fluids. Poor car was quite thirsty for oil, coolant, and power steering fluid. With the hood up, I notice coolant has leaked into the engine compartment.

The radiator hose had been rubbing on the alternator pulley and abraded a nice hole, causing a decent leak.

Back inside for some gorilla tape and zip ties. Not my best repair but good enough to get it home until a new hose arrived.

Part came in Monday and she's right as rain now. Gonna keep the tape in the car just in case another hose decides to give up the ghost.

The Dung Heap / Chip On Board LED flashlights
« on: February 08, 2016, 06:24:03 PM »
I only recently learned about chip on board (COB) LEDs recently while watching some Youtube vids. They looked pretty impressive.

While at a local bargain store, I spotted a little flashlight/floodlight, with a single LED on one end and double LEDs and reflector on the side - $4 w/ 3 AAA batteries included. I tried it out and the amount and quality of light is amazing. Pure white, not like those cheap Arbor Freight freebie LED lights with a blue tinge. And it's much brighter than my LED Maglite I've had for about five years. It actually puts the Maglite to shame.

The guts look quite nice. Solder joints are neat. Poor idea running one battery cable directly over the other but overall it's very well done.

Dunno about battery life yet. I intend to use rechargables once these are flat.

Excellent tool that's sure to get a lot of use every day. Guys, this cheap Chinese garbage is actually getting good.

DIY/Fix-It Up/Repair / Keurig Overheated
« on: January 20, 2016, 08:32:10 PM »
I have a Keurig with a color LCD that I took home from the office. It was leaking so they tossed it. This was about a year ago. I just got around to opening it up and finding the leak.

I disassembled most of it and foolishly removed a small TRIAC from the bottle metal case where it was dispersing its heat. When I ran it with the TRIAC floating free, the machine powered on and heated the water. I saw where the leak was (small plastic fitting) and it was no big deal to replace. Then things got too hot and the water in the reservoir began boiling. Steam and boiling water shot from the output into a coffee cup I had placed beneath it. I unplugged the unit. The TRIAC was red hot.

Now, even after it's been allowed to cool for days, the LCD displays "System Overheated". I'm not sure if the TRIAC is toast or even had anything to do with the overheating. Last time I used the machine months ago, it wasn't overheating. There is what looks like a thermal protector on the side of the water reservoir - not sure if that's at fault until I bring home my multimeter.

It's hard to find any info on these Keurigs. I googled around and can't find any way to resolve the "System Overheated" error. I ordered a new TRIAC and will check out the thermal protector or thermometer. Heard of anything like this? Any ideas?

DIY/Fix-It Up/Repair / Broken laptop hinge
« on: November 30, 2015, 10:56:44 AM »
Had an old customer call me with a busted hinge. It's an expensive laptop so I suggested with replacing it with an OEM lower chassis... Or the less expensive alternative of drilling and screwing. She chose the latter.

I omitted some pictures but essentially, the plastic stanchions on the lower chassis break off and the brass inserts with it. These are what hold the screen hinge in place.



I drilled through these holes, through the lower chassis. I then sent some screws up from the bottom, with a lock washer and nut on top. A bit of loctite will ensure they don't come undone. It works surprisingly well and ought to last for a very long time. As you can see from below, there's hardly anything different cosmetically.



I'm pleased with the results. Will definitely replicate this in the future.
