So yesterday i picked up a blade for my garden tracor for super cheap. It came with a mount but does not fit my tractor - No problem, i have a welder and can fabricate one. I am trying to decide how i want to raise and lower the blade when reversing or not using it. My options are as follows: Electric linear actuator : $40, or a 1500lb electric winch: : $70.
Cost aside, which route would be better? the linear actuator is only good to 250lb. The blade only weighs 70, but the angle at which it would be pushing up might make it seem more.
>>930495 If the tractor has an option for a plow on it theres normally already a bracket on the deck lever that you can attach to the blade. Mine has one in the middle of the deck attachment points and pushes a rod forward to lift the plow.
Situation: I want to use an arduino to have my dorm room open with my phone and/or a keypad
Problem: I can't change anything that I can't change back
What would be the best way to have the door open from the inside (mechanically) that would be easy to put back afterwards and that wouldn't ruin my door's ability to open with a key? I can deal with the actual programming etc easily, but the actual mechanism has me scratching my head as to what the best method would be.
>>930410 Get a towel rail that you hang over the door Some rope, tape it to the handle. The tape won't hold but wrap the rope around and around and around until pulling the type pulls the latch. Rope goes over a pulley on the towel hanger. Other end of rope tie it to a paint can and fill with sand or bolts until its a decent counterweight. Drive pulley with motor indirectly, use a rubber wheel as a friction drive or a belt and pulley to turn the main pulley.
>>930373 To anyone as clueless in electronics as I am, this is an amplifier I'm using to build speakers, the point of the diagram in the op is to reduce the ripple from the wall wart powering the amp. The high ripple from cheap wall warts would cause the speakers to emit an irritating buzzing sound.
>>930373 Hi OP, I was the guy who drew that diagram. I'm glad it worked for you, did you not need to use that unconnected capacitor on the desk in the end?
As to your question there was a guy who showed me a technique on how to take iron cored transformers apart (to scavenge the copper wire). The core laminations would not come out but he said that all I needed to do was chisel them out with a hammer and flat head screw driver. 10 minutes later and the job was done.
Another time I had a strange looking connector... Comment too long. Click here to view the full text.
>>930349 A 2N3904 is a single transistor, and isn't useful as an amplifier by itself. Most amps use a lot of transistors. It's not a simple subject. This is a website I have been gleaning information from about amplifiers for over a year now.
I have a light with a grounded plug that I want to use on a timer I have on hand. Problem is the timer only accepts two pronged cords. Could I use one of these cheater plugs and connect the ground tab via ring terminal to a grounded cord plugged in close by?
I'm making a DIY light/reflector for some plants and because the reflector is going to be made out of metal duct I thought it'd be a good idea to ground it. I could just stop being cheap and spring for a grounded timer (like $12), but where's the fun in that?
/diy/nosaurs, I'm looking for an indoor house plant that is very hardy and quick to use liquid. I play a lot of online poker and keep knocking my Gatorade bottles over during long sessions. I cant just get up to piss. I've got to keep playing or lose my stack. I'm looking for a plant I can set next to my battlestation and use as a urinal. It does not need to handle excrement. Only urine. "Piss plant" in google only brings up batshit crazy claim for a hybrid coleus that's suppose to repel cats/ dogs from gardens. I need an indoor human urine variety.

OP here. >>930311 This is not a solution. This is the current problem.
>>930312 A tube to the toilet is great, but I live in a basement. Having to run a hose up steps and around the corner will be problematic. That's why I need a hardy plant. The only real light down here illuminates from my monitor.
>>930282 What kind of pump is it? If it is an in-well submersible pump, check the electrical wire that runs down to the motor for wear and tear. They tend to vibrate on anything they touch and short out eventually when the insulation is worn off. "Torque Arrestor" can help stop the twisting motion. I have like 3-4 on mine. However, the pump motor uses so much electric that the wires can actually move a fraction of an inch, especially if they are in a conduit pipe anywhere. This too can short them out by rubbing the...

My friend came across a multi-line intercom box with the microphone (Hamilton Air Model 3001-6 Multi-Lane Intercom, to be exact), and I was thinking about using it as my computer's new microphone. Any thoughts on how I could accomplish this?
in 2016, no sane person should be using an analog mic on a computer. the static can drive people nuts. get a $5 used Band Camp or Guitar Hero USB mic and stick the element at the end of that stick thing.
schematic looks sorta awright. i'm not looking at the last 2 drawings coz it's too much work. - the transformer is drawn wrong. there's no secondary coil. - having a legend is stupid; you have to keep shifting your gaze between the wiring and the legend. - the compressor uses two different contacts, which doesnt make much sense, unless you wanna isolate it for safety - in case some idiot wants to work on it while powered.
I have some 1/4 mono cable and I'm wondering if pulling off the end and taping the open cables and taping them to a square of sheet metal would give me a sort of contact mic? How delusional am I? Would it work?
