UV Enlargers - Part01: A 100W UV light source

To really enjoy the previous discussed processes in this channel we need a reliable and safe enlarger so we can skip digital negatives and curve adjustment all together. We'll use an enlarger with a condenser at first and later we'll build a couple from scratch for analog and digital. And if time permits we'll go beyond that, imagine printing a cyanotype from your phone. The components in this project could be replaced by others of similar functionality. Here's a list of components for this build: 1) HS: heat sink, an old computer CPU one will do. 2) LED: 100W UV light COB 395NM 3) R: Resistor 50W 25 Ohm Aluminum Case 4) Power Supply from an old PC computer 5) VB: DC-DC Boost Converter, 6) TM: Relay Cycle Timer FRM01 7) Pot: 100K potentiometer 8) PB: Momentary Push Button Switch Normal Open 9) LN: Lens + Reflector + Fixed bracket for 100W LED 10) TG: Thermal Conductive Glue Please be safe when working with high voltages and protect your eyes from UV lights.
