This is a description of how I designed and built my UV exposure box. After experimenting a bit with dry-laminate photo-resist and liquid UV hardened solder mask I decided to stop trying to improve my toner transfer technique and rather build a proper UV radiation unit for making printed circuit boards. I wanted it to

One thing we all always wish we could do when using any display is to load our own custom graphics, be it a logo, gif etc. In today’s tutorial we will show how to do just that on an OLED display using an Arduino. OLED (organic light-emitting diode) display is a display based on light-emitting diode (LED)
Displaying Customized Graphics on OLED display using Arduino Continue Reading
There are two things that you don’t want to do with any rechargeable battery on a routine basis: Overcharge it. Overdischarge it. While the above are true for lead-acid batteries, they are particularly true of Lithium-Ion chemistries, but for different reasons. With Lead-acid batteries: Lead-acid batteries – particularly the “flooded cell” types (e.g. those to
