Companies are an awful trend.

Most of the time cheaper products are better for the environment when they’re durable. A very simple whistle has hardly any parts that could fail easily and is therefore durable.

See the cost of veganism, prefab buildings or electric cars. If local production and local distribution of objects saves transport and handling expenses, which come from people expending time, keep in mind those people need to be fed and have to get to work somehow, then that is a fact.

This is incorrect, the author says that he prints whistles for 5c a pop, which is cheaper than dropshipping from China. This also implies that 3D printing whistles at home in that fashion is more productive when one doesn’t live in China (or next to a whistle factory).

Cheers! Much obliged. Will definitely be adding ESD protection.

I based the USB power circuitry on a reference that assumes Micro-USB and I know that USB-C is really different when it comes to power. I’ll see that I put a resistor there, as you did.

The point about connecting up the redundant pins is also an interesting one, think I need to look into the PDF for the specific part I’m using to know what extra work is necessary, if it is necessary. 👍

OK, that reassures me.

I’ll get to swapping the caps for bigger ones though I do like the challenge of soldering them.

The spirally tracks/flourishes I added simply because of looks. No intentional RF stuff going on here. I have the track smoothing plugin installed and felt bad about not using it. Besides, the switch goes directly to ground here so having a bit of “cable salad” probably won’t do any harm, I could even draw a little Tux on the board if I were so inclined…

Thank you by the way!
