#StuffMadeHere really is a "#GearWhore"...

I like that this channel shows how any little minor annoyance can be resolved given exorbitant effort and excessive time. (bro) #StuffMadeHere
😲 Wow! Amazing concept: A virtual camera lens where objects appear larger (!) the further they are from the lens!
🤯 mind blown:

Näin unta Stuff Made Herestä ja sitten isoista perhosista. Salilla tein jalat, ja lopuksi 25 minuuttia lihashuoltoa. Kävin Prismassa. Koodasin.
New Year’s resolution?
I just happened to watch https://m.youtube.com/watch?v=WsPHBD5NsS0 that has a great line: “if at first you don't succeed, reduce your expectations until you're a success” #StuffMadeHere
A very good example is #StuffMadeHere!

Putting the ‘Go’ In Frisbee Golf With a Robot Launcher
If you've gone to a local city park lately, you might have noticed strange metal baskets on poles with chains dangling free. These baskets are spread out throughout the park seemingly at random. For the uninitiated, Frisbee golf (sometimes known as disc golf) is a confusing concept. You might not think it, but Frisbee golf can be a very big deal to some people. [Stuff Made Here] is back with a disc launcher that he hopes will put all the disc golfers to shame.
It's no secret that we here at Hackaday are big fans of [Stuff Made Here], or [Shane] (he has his own tag after all), and for obvious reasons -- the CAD design process, the careful machining and testing, and the extremely high bar that [Shane] sets for his projects. This one is no different, and it is a tale of iteration and scaling. He started out with a simple goal: break the speed record for a thrown Frisbee.
An initial design was decided upon based on high-pressure air pushing a piston to throw the Frisbee off of an arm. Initially, the arm was way too slow as the airflow was severely restricted due to air solenoids and pressure regulators. After fixing all those problems by fabricating his own solenoid and adding a secondary tank with no regulator, the arm started really moving. However, [Shane] wanted it to be able to be arm-mounted, so making sure the torque wouldn't melt his arm bones was an important priority.
A counterbalance was added to cancel it out, but that ended up causing additional problems down the road, so the throwing arm had to be made as light as possible. The gripper mechanism had to be redesigned again and again as each time the speed was increased, a new problem arose. Turns out that small plastic discs being accelerated at many G's tend to deform and slip out of their holders, no matter how well engineered. So [Shane] switched to a clever new design to pull the Frisbee along rather than push. It was too dangerous to really be handheld, and the only tests while he was wearing it were at very low amounts of pressure and power.
Testing it in a wide-open field at full power showed promise and while he had plenty of speed, he wasn't able to beat the distance record. Breaking the distance record is much harder as Frisbees aren't really designed with the sheer acceleration that [Shane] is subjecting them to, and they want to flip. Additionally, the Frisbees are lacking the spin that would keep them more stable, and what we do as humans is quite difficult to reproduce. Maybe a larger-scale version of this disc launcher could be made that accepts Frisbees?
It's incredible to watch this contraption come together as each part needs to be designed and machined first by [Shane]. Video after the break.

Building An Archery Mech Suit To Skip Practice
According to legend, King Edward III once said: “If you want to train a longbowman, start with his grandfather.” Consistently making accurate hits with any bow, especially on moving targets, takes many hours of practice. Or, if you're [Shane Wighton], you can spend a comparable amount of time building, debugging, and rebuilding an robotically-enhanced bow to do it.
The goal was to shoot flying targets out of the air, so [Shane] had to create a system that could track the position of the bow and the target, and automatically adjust the position of the bow and loose the arrow at exactly the right moment to intercept the target. The position tracking was done with the same Optitrack cameras [Shane] used on his robotic basketball hoop, with reflective marking balls on the bow, target, and the release mechanism. The auto-aiming is done with a two-axis rack and pinion mechanism driven by a pair of stepper motors. [Shane] first used the cheapest recurve bow he could find online, which caused accuracy issues likely related to the Archer's paradox. The setup also made him repeatedly hit himself in the face, because the servo-operated release mechanism would release unexpectedly without having a proper anchor with his draw hand.
[Shane] eventually upgraded to a compound bow, which reduced the tension he had to hold while lining up the shot, but also increased the weight of the system dramatically. This leads him to fully embrace the mech suit look, and use a Steadicam vest to hold the weight of the bow. This finally allowed him to reliably William Tell shots and hit the flying targets.
Whether it's an all-in-one electronic golf club, an explosive baseball bat, or a robotic pool cue, [Shane] is certainly adept at using impressive engineering skills to compensate for his lack of physical skill, or just his willfully closed eyes.
