Tell us about yourself!
Perhaps consider Lost PLA?
Adding a ground plane defeats the object of having a circuit board that you can see through.Might as well just be on fiberglass board.But from a circuit design point, what you say makes sense.
Why is it pointless?The technique can be used for installations that are not just functional but artistic too.Imagine a digital clock where you can see through the clock to all the circuits. Art painting are pointless. Just take a picture.But people still do it and enjoy it.
Yep. I tend to agree.Far easier cuts on a table saw with a sled and stop block for each runner. Or even a chop saw.Either way much less cutting and waste that way.But a nice idea none the less.
You can buy 12% Hydrogen Peroxide quite easily.I bought some from a seller on Ebay, it's food grade but works just as well. I've not tried it for etching.
Can I recommend the U8g2lib in preference to the Adafruit library.It is MUCH smaller than the Adafruit library.A little faster too I think.
I love the idea.I just wonder how many shop owners are going to go..."Woah woah there?! What are you going?!":)
UV LEDs might be the way to go to get that 'not quite right' look.
Looks amazing!I hope you get to post the code up soon as I can't code in Python at all.So would not be able to re-create it.I assume that this would run happily on a standard Raspberry Pi 1?
I'll be honest.I rarely vote for Instructables in the competitions.However.Having read a particular comment which said your instructable was difficult to follow and irrelevant.I have voted for you.
I too have not used PETG.But I understand it is VERY difficult to glue. So a one piece ring and hinge design might be a better idea for PETG prints.
I recon he used the charging module to act as a voltage dropper for the leds.As stated a resistor would be cheaper.Or. Just connect an old lipo phone battery and make it wireless. ☺
Why not use an led strip instead of individual led's?Easier to wire up.
