Wykonany od podstaw elektroniczny prędkościomierz do motocykla MZ ETZ. Prędkościomierz współpracuje z impulsatorem z Lanosa. Cewka powietrzna pochodzi z zegarów z Renault Megane I z 1996r. Sercem układu jest mikrokontroler Attiny2313 który steruje zarówno wyświetlaczem LCD jak i cewką powietrzą (poprzez mostek L293DD). Wsad zajmuje 2024 bajty (czyli prawie 100%), sterowanie wskazówką zostało zrealizowane przez programowy PWM.

Awesome job! How did you create the housing? The clockface, the glass, the case.
I used original MZ ETZ box from speedometer. Only clock face and electronics are created from scratch. It is build from laminated prints on paper and foil glued on plexiglass. I will post more pics if I will find it.
I see. It’s incredible!
My hobby is to restore old stuff, until now I only did with old computers – like Commodore 128. I’m extending the product range to motorbikes 🙂 I just bought an old ETZ 125 in a pretty bad condition. I’d like to restore it, and make a few modernization – like these clocks what you’ve created. I’m a computer engineer, so I have the technical background for the hardware and software part, but I have no clue about how to create a case, clockface, pointer etc. I’m thinking about to use a 3D printer to print the case.
I would appreciate if you could upload more photos!
Do you still have the machine? 🙂
