Remnants of The Past: The First Project, The First Tesla Coil


This is a Remnant of The Past, the first project that started my journey on the road of electronics. The thing you see above is the first Tesla Coil I ever built, and the first project ever having to do with electronics. This project started sometime after I started my first year in high school, looking back it has already been 5 years since then. It all started when the younger me had watched Read More

Making of the DRSSTC H-Bridge: Part 1

This post or let’s say series of post because the process will be split into different sections to make it easier to read.

Ok so now I have a design, but that’s pretty useless so how about we make it a reality.

First of all, I needed a blank photoresist board and those didn’t come in the sizes I needed which was 150×244.12 mm, so I just bought some Kinsten presensitized PCBs from my local electronics shop ( Cost about 81 HKD, not to bad when compared to RSonline prices ). It was the perfect height so I didn’t need to cut it horizontally which saved me a lot of work, I just needed to cut it to length at 245 mm.

DRSSTC-Bridge Cut Boards

I cut it by scoring it with the yellow cutter you can see in the photo, I scored each side about 30-40 times then I snapped it which was quite easy to do, I filed the edges afterwards. The fiber glass eats blades like crazy so I prepared a few backups and of course when doing such work take care not to breathe in the glass fiber dust which is a serious carcinogenic meaning it can cause lung cancer if you experience prolonged exposure.

Well now the next step is to expose the board which I will be doing in my next post.

Part 2 is out! Read it here.
