If you need an UV LED timer, or a timer for any other purpose you may be interested in the UV LED Controller that was constructed using a PIC 16F628A Microcontroller. There is a schematic and code available however the original project was not documented in English. Have a look at the Google translation that did a decent job of translating this one.
Here is what you need to build it.
"- The LC-Display
- 1×16 headers man and female — 1×16 headers male and female
- 4x drukknop
- 4x pushbutton
- 1x PIC16F628A met voetje, 18pins — 1x PIC16F628A with socket, 18pins
- 1x 10kO potmeter — 1x 10k O potentiometer
- 1x 100nF condensator — 1x 100nF capacitor
- 1x 220uF / 25V condensator — 1x 220uF / 25V capacitor
- 1x 7805 spanningsregulator — 1x 7805 voltage
- 1x BUZ11 — 1x BUZ11
- 1x Rode led — 1x Red LED
- 1x Connector — 1x Connector
- 5x SMD weerstanden — 5x SMD resistors "

Excellent! I’ll use one of these on my portable exposure box for circuit boards!

Thanks for the translation. Dutch is relative similar to german, but english is more understandable
