I need to learn how to make PCBs with UV method and I've create simple test board. Heart-shaped led blinker :)

Step 1: Materials:

You need:

- STM32F030F4P6

- 12 LEDs SMD (0805)

- 12 resistrors 1k 0805

- 3 resistors 10k 0805

- Battery connector and battery

- one SMD PMOS

- one SMD switch

Step 2: PCB:

My firsts PCB with UV method.

Step 3: Soldering:

Step 4: Cutting the Edges:

I use my dremel to cut edges.

Step 5: Create Animations:

I've made PC app in C# to create animations.

Step 6: Final:

Movie with animations (before cutting edges):


Visit my Youtube Channel and simple blog.

<p>I have made a heart shape a few years ago with pic12f629. It has only 8 legs, but that's enough for 12 LEDs. With one cr1220 battery it is working for a year or two (depends of how much do you turns it on) and the full shape is only 4*4cm.</p><p>The source files are available on my page (hungarian): </p><p>http://bence.zahalka.hu/2014/02/14/villogjunk-valentin-napon/</p>
<p>hey, nice project :) destination for my board is test how easy can I make PCBs with UV method.</p>
aside from a few pictures this isn't an Ible.
