Re: 1st time on DCG Project
Yup, seems like you put too much dichromate and it crystallised out.Zeta wrote:Yes

Re: 1st time on DCG Project
Did the plate look like this prior to exposure?Zeta wrote:Ummm. This is bad.
Is this because too much dichromate?
Or just my bad coating?

Re: 1st time on DCG Project
Hello my new laser just arrive this morning. 532nm 50mw About the old one the amber light is on about 40-50min and then off and back on again but no laser. About the new one, is this expanded beam good for the reflection hologram? S__25460912.jpg or just shine the plate everything will do. Looks go...

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...
