UV LED MOSFET driver board for custom PCB light etching

This is a a MOSFET driver board that can source 4x 1A of current to 4 separate arrays of ultraviolet LEDs. The purpose of this project is to design a UV exposure box that can develop photoreactive printed circuit boards. I didn’t have a large bench power supply that can supply 4A of current to […]

Review and teardown of UV nail polish curer and PCB developer.

This unit is a very common UV nail polish curing unit available cheaply on ebay. It uses four 9W UVA tubes like the ones found in insect traps and UV exposure units. The unit has the option of continuous or timed operation with a fixed time of two minutes. I experimentally exposed a piece of […]

Insoladora “6u” DiY PCB exposure UV box

This is my DiY PCB exposure UV box. It´s made with an old HP scanner, two UV anti-mosquito devices and a programable timer with relay. It expose an normal PCB in about a minute, but normally i set it to 2 minutes. Esta es mi insoladora casera. Está hecha con la carcasa de un viejo […]

pcb uv exposure unit

contains 3 pairs of pc blacklight lamps and a custom timer with lamp compination selection and pre-heating stage for 2 minutes. It uses a pic 16f628 programmed in C and an ready made power supply giving 12V for the lamps and 5V for the microcontroler board. The casing is made out of an old computer […]

Making a led UV exposure box

In this video you can see the process of creating a UV LEDs exposure box, which you can use to make your own printed circuit boards (PCBs). The full process and more info in electronics, robotics and DIY projects in general in my blog: vlxs.wordpress.com source
