  • Plating through holes is going to be a fun project. There are kits for doing that kind of thing, but you will pay a premium to get everything in one box. The last time I researched it, some conductive ink/paint/glue and an simple electroplating setup was going to be the best option. (The low resistance conductive ink at the time was super expensive, and I was super broke, so I had to ditch the project ) For diy, copper rivets seem like the next best option, TBH.

    Take lots of pictures of your wins and failures in your multilayer board project. I have no clue how you are going to be able to press the layers together while keeping them aligned, so I am super curious how that will go.

    Those projects are super fun, but are a time suck because they tend to have quite a few iterations before they are usable. Sigh. Work and kids basically terminated those kinds of projects for me.


  • It depends on what kind of IC you need. If you need an authentic part that has been tracked and verified through every step of distribution, you pay a premium.

    For hobby products, sure. Spend 30 cents on that 5 dollar part.

    However, a bad batch of fake ICs could potentially cost a company millions of dollars in returns, or worst case, liability lawsuits. (It has personally only cost me a few bucks and some wasted time.)

    My personal trust in any Chinese sourced electronics is zero. It’s less than zero if I attempt to buy a proper name brand IC. I ain’t salty about it since I know my odds of getting defective or improperly labeled (or relabeled) parts: Expect about a 30% failure rate or parts that are way out of spec.

    Simply put, QA is generally poor and the supply chain is sketchy. If that doesn’t matter to you, so be it.

    What happens is it chips do come from the same Chinese manufacturer, you can get spectacularly different grades of parts depending on how you bought them.
