Hi there :)
I was asked to recreate the idea demonstrated in these awesome setups:
-> of course, Kudos to the respective original author ;)
Now, after a quick read of the schematic involved:
I could start a new version :)
Now, all that is good, but looking at the code ( whatever the version .. github.com/cubic-print/timeframe/tree/master/software) , it seems to be using some register's mambo-jambo tricks specific to the AT328P for precise timing purposes ( .. )
I was wondering if I could achieve driving LED stripes in a "stroby manner" while simultaneously driving correctly the electromagnet using only js ( actual DACs or using PWM .. ) or if I had to look into writing a quick module that'd allow me to do so :)
Long story short, the objects getting vibrations from the electromagnet have to oscillate at 80Hz while the LED stripes have to strobe at 79.5Hz to get a "beat freq" of 0.5hz, perceived by our eyes as a very slow motion ( etc .. ;p )
For the fun of it, if anyone has hints/advices on the above, remember the "water + subwoofer + camera ( filming at 24 fps ) + audio waveform" trick ?
By modulating the waveform from 23Hz to 25Hz, the water appeared to go backward or forward and also gives a really nice effect ..
.. so another question may be how to replace the camera fps' by strobe lights while having those oscillating at a freq enough for our eyes to perceive the motion ? ..
Looking forward to reading some answer on this,
Happy coding !+
