I got the circuit board back from JLCPCB a few days ago. Although I was excited but with some Fever mixed with bout of the Flu, Gout attack and a tennis elbow all rolled into one, I had to stay in bed as soon as I came back from Work. Just sitting on the Works Table with an aching arm and sore bones just really dampened the mood to the point of me becoming depressingly suicidal while everyone was able to chip in with the House work.
Why flexiPCB?
As we all know, circuit boards, like its namesake, is a board. A solid, unyielding fibreglass board and the Tesla Emitter arm is curved. Designing it to conform to the curve can be summed up into one word: expensive. Not impossible but expensive.
This was very true for the last two years as decades ago, as although flexible PCBs were used in manufacturing, they were quite expensive. But just over the last two years, JLCPCB has successfully made my dreams come through (nevermind the *ahem* Projects I did and prototyped during the Pandemic.). And it is so much better than heating and bending the 0.8mm FR4 PCBs into shape. Imagine doing it to just three boards would already be a nightmare and a possible fire hazard.
How now, Brown Cow?
Now, we wait. Because the Ice Blue 0805 SMD LEDs which I bought some time ago cannot be found. I’ll have to search for it once I am well but just to be safe, I am ordering some more, which would arrive sometime before April ends. Or May begins…
