You say to yourself, “Self, I want, nay, need a lathe”. Being a good little trooper, you then did all your research, having chosen Import or American, Imperial or Metric, and all your feed options and such. You then pulled the trigger and the machine is en route to your shop. Now what?

Some people are better than others when it comes to documenting their hacks. Some people, like [Micah Elizabeth Scott], aka [scanlime], set the gold standard with their recordings. Hacking sessions with the Winch Bot have been streamed regularly throughout the build and this is going to lead to a stacking effect in her next projects because the Winch Bot was designed to record hacking sessions. Hacking video inception anyone? Her Winch Bot summary video is after the break.
The first part of this build, which she calls the Tuco Flyer, was [Micah Elizabeth Scott]’s camera gimbal hack which we already covered and is a wonderful learning experience in itself. She refers to the gimbal portion as the “flyer” since it can move around. The Winch Bot contains the stationary parts of the Tuco Flyer and control where the camera will be in the room.
The trademark hacker style of Hessian YouTuber [Homo Faciens] is doing a lot with a little. Given a package of parts from a sponsor, he could have made something “normal” like a fancy robot arm. Instead, he decided to make a winchbot. (Video embedded below.)
What’s a winchbot? It’s a big frame that supports three relatively heavy motors that pull steerable gripping arms around. It’s a little bit like the hanging Hektor / wallbot / plotterbot and a little bit like a delta-style 3D printer. Although [Homo Faciens]’s build doesn’t showcase it, a winchbot is also a great way to lift heavy things because the parts that need to be beefy — the frame and the lifting motors — don’t have to move. We love the gimballed square rod that works in concert with the winches!
With five extra servos on hand, and the computing power of a Raspberry Pi, [Homo Faciens] couldn’t just stop with lifting a claw. Instead, the gripping-arms part of the bot is mounted with four degrees of freedom and is powered with software that makes it stay parallel with the table and rotate around the gripper to make programming easier. Watch it in action in the video to see what we mean.
The biggest unsolved problem that we can see is the jerkiness that it displays in moving things around. That doesn’t stop it from building up a tower and a domino knock-down. We suspect that there’s some combination of firmware and hardware tweaking that can solve this problem, or it could just be run slowly so that the wobbles damp themselves out. We’re also quite confident that [Homo Faciens] will come up with an elegant and cheap solution. Have you seen his CNC machine?
We’ve seen a lot of hacks from [Lou] and his latest continues the tradition of excellence. The entryway of his home is a couple of stories high and features a chandelier. Unfortunately he doesn’t have a ladder tall enough to use when changing light bulbs. Even if he did have a way to get up there it would be nice if the light fixture could come to him instead. This hack makes that happen by adding an electric winch to lower the light fixture.
Watching the installation process makes us think that [Lou] might be a little reckless. He’s up in the attic mounting a winch to the rafters before he cuts the board holding the fifty-pound chandelier’s junction box in place. He mentions foregoing the recommended cable fastener in lieu of some baling wire. But he does manage the task without dropping the ball so to speak — perhaps we shouldn’t be so critical of his methods. After altering the chandelier mounting bracket to work with a winch [Lou] wires an outlet in the attic and adds a plug to the cord on the light. This means he needs to go into the attic to unplug the light before lowering the fixture on the winch. But he’s not done yet. After the break you can watch the second part of the project with improves upon this by adding a wall switch to control the winch and extension cord management to route the power.
[Lou] really loves his automated home gadgets. Check out the gaming table which drops from the ceiling.

As every kid quickly finds out, sledding in the winter is awesome until you have to trudge back up to the top of the hill. If your sledding run is reasonably short, this isn’t a problem, but if you sled on huge hills like [Josh], you need to figure something out.
He had a go kart motor sitting around, so he figured he might as well put it to good use as a sledding winch. The winch runs a continual loop of over 1000 feet of rope, and is able to pull 3 adults up a 30 degree incline fairly easily. They say that necessity is the mother of innovation, but at some point you have to ask, “Does sledding really require an 8 HP motor and a continuously variable transmission?” The answer, of course is a resounding “Yes!”
Not only does this winch allow [Josh] and his friends to get back to real business of sledding in a hurry, it actually makes sledding fun in both directions.
Keep reading to see a video of the winch in action, and be sure to check out some other fun uses for winches we have featured in the past.

Here’s a build log for a nice beach winch for your next trip out to go beachwinching. Beachwinching is when you use a fast winch on shore to pull you in, allowing you to wakeboard, wakeskate, or water skii without the need of waves or a boat or jet ski to pull you along. While there’s nothing amazingly groundbreaking here, we do love a nicely documented build log. We think a remote way to initialize the pull would be nice too.
You can catch an example video of beachwinching after the break
