Post your "ghetto rigging" shenanigans - Page 676

post #6751 of 7231

I welded and painted a front "trunk" for my e-bike.

I still wait for other parts like new gears and freewheel.
I'm basically changing entire crank.

Instead of current worn-out standard crank I will put there a custom-build crank.
2x28T gears mounted on a freewheel. New crank has freewheel thread.

This will stop the pedals from moving.It's not the cheapest way but the most universal one.
The cheapest way is flip-flop rear wheel(gears on both sides, usually one fixed and one freewheel) but getting 24" wheel in such variant is hard.
It's only cheap if one is to purchase flip-flop hub and simply convert rear wheel.

Have u tried if 26" wheels fits on your bike ? I have 700c wheels on my GT Agressor 26" and they fit perfect.

Changing hub and get the wheel on center is a bit tricky ... i made this tool with a old fork for that job biggrin.gif

Genius! Where did you find such tiny fans though? Old laptops maybe?

Here is mine,RC airboat buit from juice bottles, zipties and a piece of MDF. Used an old RC car remote control connected to a relay to power 2 PC fans, it works and everything but I need a worm gear drive for the rudder, better start looking for a Vcr player to scavenge one from! thumb.gif

Looks good.

The fans above look like normal 40mm fans. They used to sell HDD coolers that worked along the same lines.
My system from 2002-2003 smile.gif look at the cooler under the optical drives smile.gif You may also see screws holding a fan on the side of the case.

Those were the days hahah, my friends used to buy music CD's and then burn them onto CDR's, and we would exchange burnt CD's with each other to get new albums!

Interesting about those HDD coolers, I have opened many old 90's to early 2000 era computers and never seen one before, hang on to that beast as it might be getting rare soon, I know I had great difficulty in finding things like AGp cards when I was fixing up this old 90's emachine I had, suprisingly it still works in all it's pentium II glory with an (upgraded) 64mb ram!

Got a bunch of stuff again...

Makeshift water heater (Click to show)
I ran out of propane for my stove so I couldn't brew my morning tea. Usually, I would've went to the garage and brought a new tank but it was 5 in the morning, I wasn't willing to carry 30kg of crap up to the second floor that early. So, two PCI brackets, one zip tie and a molex connector later...





Not all that healthy but I don't exactly give a damn.
Fan controller from random electronic scrap (Click to show)



I used an LM317T and 550 Ohm resistor I pulled from a satellite receiver that is now my HTPC's case, 5K potentiometer from god knows what, used test board out of a dumpster, 3-pin fan connectors from a dead ASUS A8S-X (and one from a molex adapter), heatsink from a dead PSU and the male lugs from some scavenged vacuum cleaner electronics (by the way, Electrolux vacuum cleaners suck, literally and figuratively).

Since the heatsink lacked it's supports (got ripped off) I bent a paper clip into a U-shape, put it upside-down over the heatink, pushed it through the holes on the board, tighten the heatsink down with it then bent it's ends and put a big blob of solder over them to keep the thing in place. I taped a piece of pink cardboard on the bottom of the board with electrical tape so it can't short-circuit on anything, also taped a zip tie onto the cardboard for mounting. And that potentiometer is superglued onto the 5.25" bay cover cause I didn't have a nut to tighten it down.

Works pretty good, fans run at 9.8V tops due to voltage drop but I can't say I care much, I didn't mean to run them over 9V anyway.
Charging a GPS (Click to show)


I found that GPS in the trash but the adapter in which that cable plugs in was dead so I just jump-started the PSU and tied it's 12V cables to the lighter plug. I also put the GPS on top of the PSU's intake fan to cool it down a bit as it runs fairly warm while charging.

And after testing the thing I realized why it was in the dumpster I pulled it out of - it's signal reception sucks, works well on open road but loses signal in the city frequently, it's battery is crap too. Ah well, don't look a gifted horse in the mouth and stuff like that. I'll try to trade it for some DDR, my s939 machine could use more RAM.
Speaker box out of plastic cups and toilet paper (Click to show)
It's a crappy speaker, it deserves a crappy case.



Construction of the thing is simple - there are three cups in total, the inner most cup had it's bottom cut off so I can install the speaker more easily while the two other cups have a hole in the back through which the cable is routed. The 1W speaker I ripped out of a dead radio is just jammed in there, the cups are inserted into one another with two sheets of toilet paper between each pair of them, and I also put some toilet paper over the speaker since I find it makes the sound a bit better (plus, it prevents me from sneezing all over the thing).

The "science" behind it is that multiple cups and toilet paper is supposed to reduce harmonic vibrations and increase structural integrity. Does it work? Not really, although it does improve sound quality when compared to the speaker's original case.
Fixing my soldering iron (Click to show)
The cable on my soldering station crapped out, thermal probe wire broke somewhere so the thing gave a "no temp reading" error and beeped like mad. I was hoping it wouldn't fail so soon, the cable is cheap crap and finding a 5x0.5mm cable with 6mm outer diameter is a pain in the arse for me. While I was swearing and heading to unplug the station so I don't have to suffer it's god-awful beeping, I tripped over the perfect replacement.



Meanwhile, my brother spent all morning wondering why his internet connection is down. biggrin.gif

By the way, this is a damn good cable, solders like a dream too. I'm thinking of getting 10m of it for when I need thin wires for my projects, it's a bargain considering that 1m of ethernet cable is less expensive than 1m of 2x0.5mm speaker cable over here ($0.4/m vs $0.75/m) while I get four times as many wires.
Nokia Radeon HD 5570 (Click to show)
I was subbing a DDR score for the HWBOT team cup but my card is finicky, it's rear had to be bumped up slightly to pass POST for which I used some 3310s.



Taped two phones together with electrical tape (the upper 3310 keeps the one bumping the card on target) and pushed them onto the card with a cable tie. Functioned well enough.
DIY first aid kit (Click to show)
In case you didn't know, electrical tape and toilet paper make for an excellent emergency bandage to treat burns. I give 'em a big thumbs-up.



By the way, those aren't for show, my soldering iron fell off the desk and I instinctively grabbed it. I must say, that was a pretty bad decision.
Made a water battery (Click to show)


Solid-core copper wire and zinc-plated nail submerged in saltwater. Lemons would have been better but life gave me a bag of salt instead.

Why did I make it? Power was down that day and I wasn't wiling to sit in the dark all evening so I hooked up an LED to that thing. Yeah, I could've just used a 3V battery from a mobo but where's the fun in that?
Cardboard air conditioner (Click to show)



I put a bottle of almost frozen saltwater in a cardboard box with two holes in it, taped a fan on the hole up top and voila, air conditioner. Top of a CD box under the bottle is there to avoid condensation wetting my folder, the fan is taped onto the box cause I misplaced my baggie of fan screws and there's a folded A4 paper taped where a piece of the box was torn off.

Kinda sucks but right now I just don't care, anything that cools the air in my room is good, I'll jam more bottles in there later for better performance.
Laptop power brick modification (Click to show)
The local mountain rescue service was throwing away old equipment from their office so after some dumpster diving, I got my hands on three Compaq Evo N1020v and two HP ze4300 laptops. All of them were dead and cannibalized for spare parts to keep their working laptops working but I managed to assemble a fully functional n1020v. Battery lasts for 10m, the touchpad is crap and P4 is slow but who cares, I have a laptop for college. wheee.gif

One little problem though, there was no power brick in the dumpster and the only one I have is a patched up HP one (from my mom's nx6110, I think) which I can't even assemble properly cause I misplaced it's cables and half the casing. So, random adapter plug, desk lamp cable, some wires and a few row terminals later...



I also had some trouble inserting the plug since it's a bit too big to get in the charging port but it was nothing my drill couldn't fix. And no, I won't be running the power brick naked, I superglued it to the bottom of it's original casing so I can't fry myself while handling it and I'll wrap the rest up in packing tape after making sure the thing won't catch fire.

Speaking of catching fire, the laptop's cooling will require extensive modifications. Someone at Compaq thought mobile Pentium 4 is not hot enough to be used in a laptop so a desktop chip was crammed there instead. I already popped the lid off the CPU which helps a lot, but the northbridge and power delivery are both hot as hell.
Fixing the unfixable (Click to show)
While I managed to get nn n1020V up and running for college, I also fixed up an HP ze4318EA. It lacks some parts, those being the charger port, optical drive, battery, battery charging circuitry, and some pieces of it's casing. All missing parts are irrelevant except for the charger plug which I fixed by soldering wires directly to the mobo, then securing them to the charger plug with a rubber band.




The laptop, however, has a major flaw, which is this:



That flimsy piece of aluminum with a thermal pad attached is supposed to be it's northbridge heatsink. This is not acceptable, iGPU managed to run UT99 for a grand total of 15m before it bluescreened due to overheating. Time to fix it. n1020V has a decent heatsink so I just ripped it of with a French key (or whatever the hell that thing is called).



Problem is, Compaq used some sticky-as-hell double-sided thermal tape on the thing so I needed to use quite a bit of force, now the board is dead. Scraping the gunk off the heatsink is easy, drench it in acetone, leave for a few minutes and it will peel off right quick, except I messed up and overdid the acetone part so I had to burn some of it off. Bonus pic of burning heatsink.



Then I just sat the thing on TIM and screwed a bent paper clip to hold it in place. And since it was still crashing, I also ripped out some useless slot and installed a blower fan from a PlayStation 2 in it's place.



No problems ever since. smile.gif
Improving wifi (Click to show)
I made a Yagi wi-fi antenna a few years back but I keep forgetting to buy a cable for it since my old antenna worked. A few days ago I had problems with wifi connectivity and since I was too lazy to go buy a cable, I decided to make one myself.





I disassembled a crappy "range extending" antenna which, funny enough, actually shortened my wifi range, soldered a cable from a random adapter to it's inner terminals after ripping it's guts out, extended the cable twice cause it was too short, and finally soldered it to the new antenna. And then, of course, I used zip-ties to attach the thing to my closet's handles.



I should really make a mounting arm for it.
Overvolting a CPU (Click to show)
I overvolt my CPUs with tin foil and super glue.



1.325V VID (1.312V under load) + bridging VID3 to VSS = 1.375V (1.344V under load), which bumped me up from 2.75GHz to 2.93GHz.

Unfortunately, CPU scales like crap past that point, needs +75mV for 3.03GHz. frown.gif
GPU cooler on CPU (Click to show)
Well, my HD 5570 died, it's voltage controller crapped out. Loving to recycle old crap, I decided to re-purpose it's cooler, the thing was cooling a 60W GPU so I figured it would do good on a 25W CPU. And so this happened:



Lower profile than the stock cooler, cools a lot better than the stock cooler, and it's a lot quieter than the stock cooler. Since I couldn't think of any other way to mount it, I zip-tied it. And the connector for the fan cable is just two small pieces of a paperclip soldered onto a molex cable, then jammed into the fan's contacts and wrapped in electrical tape.



EDIT: And since I've been busy today, here's some more.

USB cable RF shielding (Click to show)
I needed a USB extension cable so I soldered a female USB connector from some old charger to a USB cable I cut off a credit card reader. Then after soldering the wires together I needed some RF shielding for that part of the cable so I used this:





Orbit chewing gum protects both your teeth and your data. Aluminum isn't so great at RF shielding but it sure beats having nothing.
New crocodile clip cable for my multimeter (Click to show)


Left over from the water battery, I needed another crocodile clip for measuring some current so I re-purposed this thing.
Phone radio antenna (Click to show)


Another re-purposing, I used a wifi antenna from above and soldered it to a 3.5mm jack, figured that's a better use for it than becoming a key hanger. Works better than the bundle of wire I had there before.

Allows me to take clear pics of stuff that would usually be blurry as hell (like the Orbit package).

so im making progress on my modernization of my ibm portable faster than expected, over the weekend i threw together enough hardware to actually give it a test run.
a few things i need to really get project going *short dvi-vga adapter, 6" or less vga calbe, a powersupply in the 600w range, a front panel audio and usb thingy, and a different gpu as im giving this one to my dad.* there are more things i need but i have them laying around IE scrap plastic and plexi glass, or switches buttons and lights.
also my plan to use the luma from S-vdieo was a good one, cleard up my image big time!

Installing Server 08 (win 6.0)


Running 08 with a tweekd high contrast theme in lovely 640x480


Video of me testing it out..
also yesterday one of my friends convinced me to spend the night at his place with promise of good food and a 5:30am ride to work, i packed all my cables in my psu box and used an old lamp cord to tie the ibm portable shut and took it to his place, i had to take it to work so i set it up behind what you would call my general work area on top of a crate next to my ghetto boom box, ran the 2 together, and on my breaks me and one of my coworkers were taking turns playing BeamNG.Drive, honestly it was a bad ideah because a 15min break only lasted 5 min... so my computer speeds up time. aslo its still at work and im probably gonna leave it there all week,
oh, and i replaced the motherboard box with a sheet of cardboard as a temp insulator.
