Hello everyone !
Here's the plan to make my first mechanical computer : A Fourier series composer, made from lasercut frames and gears, a bunch of springs and a pen, to create sine waves and add them to draw a signal.
Despite my terrible grades at my Fourier's work lessons, i fell in love with the principle of this machine, and i decided to share with you the plans to make one.
I recently watched this engineerguy's video about the original machine.
The first mechanism was invented by Albert Michelson, a famous American physicist, in the late 19th century, in order to have a better understanding about spectroscopy.
Cut it in 3mm thick sheets. MDF will do the job. I personnaly used 7 sheets of 30 x 60cm to cut it all.
Screws & Stuff
- A compression/extension spring set, similar to this one on Amazon. this box is sold everywhere in the world, check out the same set available around your country. - x5 45x58x7mm 6809 bearings,
- x2 120mm Ø4mm threaded rods,
- x2 140mm Ø4mm threaded rod,
- x1 190mm Ø3mm threaded rod with nuts,
- x3 120mm Ø3mm soft rods (threaded rods can do the job),
- x20 Ø4mm nuts,
- (Optionnal) x8 Ø4mm acorn nuts for aesthetic, or else, replace it by 8 extra nuts,- x20 10mm Ø3mm bolts,
- x2 15mm Ø3mm bolts,
- a 100mm Ø6mm screw with 2 nuts,
- Ø4mm tubes with Ø3mm inside as tiny bearings like these ones, x10 8mm long and x10 5mm long,
- a bag of Ø3mm washers,
- some metal scrap as counterweight (around 500g)- x5 paperclips,- a bulldog clip,
- a pencil,
- a little note pad.
