Hi All
Started building my Dulcet and the naked PCB's look... naked.
So I got some UV curable mask paint from ebay.
It is very thick and cannot be sprayed, they also say not to dilute it but I tried anyway.
2 parts 70% Isopropyl Alcohol and 1 part UV paint. Goes on nicely and looks like most of the Iso evaporates during the spraying. Air dry for about 20 min, cover with transparency and then onto my ghansta UV box.
I made this for some analog synths I was etching some time ago. On the lamps for 90 min and the mask is smooth as silk and hard as rock.
The compressor I made as a proof of concept of a silent compressor for a linear tone arm, works very well. Gets to about 8 bars but it starts to strain about there so I let it go to about 6 or 7 bars only.
It's a tiny fridge compressor that goes to a big receiver and then on to a smaller receiver. The big receiver also acts as a oil trap because there is some oil loss from the fridge compressor, needs to be topped up every now or then.
I can also disconnect the small receiver and walk around with it spraying my weeds with a spray gun and top up with air from the big receiver.
