Electromechanical Workshop
Album
We had various mechanical parts for the machines in addition to electro-trash. / CC BY Kati Hyyppä
The Fischertechnik construction toy parts could be also used for quick gear mechanisms. / CC BY Kati Hyyppä
This is one example that I brought with me to the workshop to demonstrate a cam and how abandoned objects such as fidget spinners can be repurposed. When the crank in the back is rotated, the cam rotates, causing the mini-hammer to move up and rapidly down. / CC BY Kati Hyyppä
We had also motors and relays, as well as 555 timer circuits for changing the direction and speed of the motors. / CC BY Kati Hyyppä
Old PC power supplies were useful for powering the machines. / CC BY Kati Hyyppä
Scavenging interesting parts from the electro-trash for the first machine. / CC BY Kati Hyyppä
Long metal parts from fluorescent tube lamps turned out to be a treasure. / CC BY Kati Hyyppä
Screwing a motor in its place. / CC BY Kati Hyyppä
Testing up and down movement. / CC BY Kati Hyyppä
How to avoid the breadboard from falling (apart)? / CC BY Kati Hyyppä
Heat sink made magical sounds when poked with motor-controlled tie-wraps. / CC BY Kati Hyyppä
The second machine was a kind of propeller with a plywood stand. / CC BY Kati Hyyppä
At first a rope construction was explored, but the ropes had to go later due to entanglement hazard. / CC BY Kati Hyyppä
Testing the rotation. / CC BY Kati Hyyppä
The machine received also a bouncing lever, which made a quite angry sound. / CC BY Kati Hyyppä
The third machine was based on the idea of having a loud lever. / CC BY Kati Hyyppä
Here a giant cam is being prepared for slamming the lever. / CC BY Kati Hyyppä
I don't know where these giant metal holders came but they looked impressive. / CC BY Kati Hyyppä
The metal fence in our 'class room' proved to be perfect for attaching the giant cam. / CC BY Kati Hyyppä
Slamming test. / CC BY Kati Hyyppä
As opposed to the grand slammer, the last machine was minute and Fischertechnik-inspired. / CC BY Kati Hyyppä
A paper rolling mechanism from a discarded printer was used in combination with a gear mechanism to move paper poetically up and down. / CC BY Kati Hyyppä
