I've got about 50 of these bana lab cables for free recently so i decided to build a regulated PSU to go along with them and it turned out pretty neat and the ripple voltage is not noticeable either.

[Anonymous No.856866]

Working at a facility that takes electronic scrap has gotten me huge piles of things... My computer monitor is a capacitor plague victim that I repaired for $9. I've gotten innumerable computer parts and whole machines, including the core i3 3240 machine I'm posting on at the moment. Three or four 40-50" televisions that were also plague victims, easily repaired and sold. Most of my surround sound system, including the 7 channel receiver with HDMI input, a 10" downfiring Harmon Kardon home theater sub (just needed rewired for line input), and so many speakers...

I'm sad that I'll be leaving the job soon.

I always wonder how people throw expensive electronics away like their garbage. i recently got an expensive cloth drier which was going for the trash and opened it just to see there was only dust causing a short.

I pulled a 10 gallon, 2hp compressor out of the trash about a week ago. Nothing wrong but a 30a automotive-style blade fuse blown. Working great again, probably just a surge that popped it.

Put my borescope down into the tank and it's in great shape, so I'll probably get several years out of it.

Well I didnt go for the resistors mainly cause of the big diodes there,transistors,the buttons-switches which have a light in them,contactors and so on

I've got a garage full of old bikes. Either found them on the side of the road, in garbage cans, or given by neighbors whose kids wreck them and want till get rid of.
Cobble a couple broken bikes into frankenbikes, then either give them to friends or sell them on cl.

Also, my first car was an 83 Geo hatchback that my neighbor sold me for $70 after I helped him move his stuff into a u-haul when he moved.

About 60% of them were trashed when I got them, and the other 40% had minor things wrong, like a bent rim, bent/broken toothed sprocket, snapped brake/deraileur cable, one only had a snapped pedal and was otherwise a nice bike. Not even the crank arm, just the plastic of the pedal. It's like people don't realize that bikes can be fixed, often for only a few bucks. Bent rims and broken cable are the biggest reasons I see bikes being tossed.

the one thing that might make using those a pain is that the coils are rated at 110/120vac (yeah these are ac relays). convenient if using ac to switch things. a pain if trying to use dc (especially since the voltage is so high). i've use these types of relays to turn on ac lights using only a ldr

[Anonymous No.858786]

>>858742
aother circuit using ac relays. this one to turn on out device, press the button once. relay will turn on and remain on until the power is removed from the in and won't turn on the out device until the button is pressed.

problem with these 2 circuits is that the relay remains on for long periods so will get hot.

Got this Honda 300EX for 40 dollars, it had the body panels but I took em off because the rear was pretty destroyed. Haven't found out if it runs yet, and I don't actually know how to drive a manual ATV. I'm considering chopping it up and making a mean go kart or something since the body panels on this thing are crazy expensive and I'd rather not pay that much for plastic crap. Needs some brake fluid for the handle brake and an oil change.

Hi there!

You seem to have made a bit of a mistake in your post. Luckily, the users of 4chan are always willing to help you clear this problem right up! You appear to have used a tripcode when posting, but your identity has nothing at all to do with the conversation! Whoops! You should always remember to stop using your tripcode when the thread it was used for is gone, unless another one is started! Posting with a tripcode when it isn't necessary is poor form. You should always try to post anonymously, unless your identity is absolutely vital to the post that you're making!

Now, there's no need to thank me - I'm just doing my bit to help you get used to the anonymous image-board culture!

Atv guy here, I just experienced my first manual launch. The Atv started fine after a bit of cranking to get the old gas through the lines. Found out the throttle is sticking at about 70%. I accidentally shifted it into first after starting (dont worry I was holding the clutch) and let go of the clutch (still thinking it was in neutral) it launched forward and went about 50 feet before I got my act together and pulled the clutch and hit the brake. Damn that was fun/scary! Well now I know it works at least.
