Mechanical video recorder
Posted: Sun Jul 07, 2019 8:02 pm
Well my title is very wishful thinking but don't try never know ...See if i can get to Alberts Drum video recorder stage ...
i have not posted this project here till i tackled 2 of the mechanical problems i needed to get out of the way before i can even think about caving a bad sound signal track on a disk ..
So first was the turn table i didn't want to reuse a record player due to its size and i like to make things smaller where possible ,i am not great making stuff from scratch but repurposing junk is more my thing ...had the idea the old dvd burners might be a way to go first 2 ended up dead ends mainly due to i wanted stepper motors for the job what was on the dvd burners motor wise is not useful without gearing and fitting the geared motor for the recording arm and turn table stepper took a bit of trial and error and very much so luck with what i had handy .
What is shown todate 2 insides of dvd burners for a test bed to mount on and for the record arm ...a old large HD motor for the turn table ..a old video camera lens geared motor replacing the tiny stepper for the once laser arm ...to jerky for slow speeds...
The recording a speaker needle and other arm the stylus for play back .
This now all seems correct to at least look workable for some sound recording ...... on testing really a good 2 weeks work here and many days of head scratching almost giving up ...what i am a little worried about the stepper noise might end up on the recordings mmm..
I wanted a stepper for the turntable to test different speeds and adjust the recording speed for the audio result .
