Zigzag sewing machine conversion to treadle
@ai6yr my oldest sewing machine is electric but from before they redesigned them for motors; it’s a treadle machine with a motor bolted on… the opposite of your project, funny how things come and go
I guess easy to covert to treadle if I wanted to, though it doesn’t zigzag
@raven667 @ai6yr I guess it could be a case of “the future isn’t evenly distributed”
Depending on where and when it was sold, it may have had a treadle version in some parts of the world… mine (from the 1910s iirc maybe early 20s) was available in motor, treadle, and a hand rather than foot powered version, as well
Either way, converting to treadle is a distinct change in direction from what started around 100 years ago
@c_merriweather @ai6yr TBH I’m just using mine as a piece of furniture, it’s a nice cabinet, but it belonged to my great grandmother
This one was available in hand crank and treadle as well, when it was new 😆
@c_merriweather @ai6yr I have another one from the early 40s, and the cabinet is falling apart 😆 I think it just needs some wood glue, but it was never as nice as the older one
The cabinet may be newer, since the machine was made during the war, I don’t know they would have bothered with a wood cabinet at the time, but I guess it had to have some kind of stand
@ai6yr The source of this bike blender memory has been bugging me since I posted this, and I finally figured it out. If anybody else wants to see a musical documentary about mid-2000s dumpster diving that features a bike-powered blender operated by Alden Penner from The Unicorns (anyone?), behold Surfing the Waste:
@ai6yr “Chair bodgers” in England used foot powered lathes to turn parts for chairs
The last of them were 1950

Chair Bodgers is the name of my foot powered lathe tribute band!
Seriously though, nice work with such meager means
wow. but also wut
"One of the flay rods' gone out of skew on treadle"

It's possible, of course.
My hunch is that a treadle+flywheel mechanism is a more sustainable way for a human to deliver mechanical energy. Rotary pedals work, obviously, as on a bicycle. But repeatedly pressing a treadle with a linear action strikes me as more natural/efficient.
And it's certainly an older, more established approach.

World famous track cyclist Robert Förstemann battles a 700w toaster. Can he, with his 74cm legs, generate enough energy to create a golden-brown toast? Pleas...
omfg. this is awesome bc i showed my ex the treadle/modern sewing machine and he said 'I need a hand power microwave, so I can heat up my instant noodles like the settlers did' 🤣
@ai6yr I like this, and we should start with home exercise machines, which are designed to *waste* power/energy, pretty much by definition.
Then we can move on to exercise machines at gyms!

Peddle powered radio helped with isolation and allowed people to call for medical help in the remote Australian Outback.

In the mid 1920’s Alfred Traeger invented the pedal powered radio, revolutionising communication in the outback. The invention was integral to the founding of the Royal Flying Doctor Service, but it wasn't his only invention and he was just as innovative at home as he was in his factory.
interesting history! thank you for posting about it!
Standing Rock had a bike generator but once the solar/wind started going up, no one wanted to ride it anymore 😂
