Yup, seems like you put too much dichromate and it crystallised out.

Is this because too much dichromate?
Or just my bad coating?

Re: 1st time on DCG Project

Hard to say anything about the results without a subject. When you get your new laser system setup, I recommend doing a super simple denisyuk/reflection hologram. Also for the videos, it might be easier to keep the light and camera stationary, and tilt the hologram instead. You're exposing with a 44...

Re: Musical Instrument Holography

Once you have the hologram of piano keys, you could just put a capacitive touch panel over it. https://www.ebay.com/itm/7-inch-capacitive-Touch-Screen-Digitizer-Panel-Glass-Sensor-Kit-Driver-Board/182748491638 You can hook this up to a Raspberry Pi or similar. The screen will output XY coordinates w...

Re: 1st time on DCG Project

Zeta can you take a close up picture of the silkscreen one? Is there any texture to the coating or is it smooth like veil coating?

Re: 1st time on DCG Project

About laser I increase output from power supply to 7v and now pin 4 is 5v but still nothing. You should have found an appropriate power supply. The voltage only drops from 7V to 5V under load. There will be times, even if brief, that this load disappears. Then you get 7V pumping into this precision...

Re: Novel glass-coating methods?

Have you tried using a Meyer bar? I tried to find one for sale online some time ago, but I had trouble finding any. The fact that "mayer bars" are also known as meyer bars, meyer rods, meter bars, meter rods, metering rods, equalizer bars, doctor rods, etc. doesn't help. I'll have another...
