  • If you are buying a coin that’s already on the market as a fully attributed coin then yeah you don’t want to clean it. I buy coins that are “fresh” out of the ground so they’re literally caked with mud. They look like this so they require cleaning. Properly cleaning 2000 yr old coins is a months long process involving microscope and very deliberate & precise application of effort. For some reason I find it very relaxing, almost like a form of meditation. It’s a hobby that I’d love to share the results and talk about with others.

    Shameless plug: You can see some of my Before/After pictures over at !ancientcoincleaning@lemmy.world :-)











  • Not always, it really depends on what the person who did the board layout or wrote the firmware thought. When I do a board/firmware I label it from the devices perspective, so the TX is where the bits I’m transmitting will be coming out of, RX is where I’m expecting your bits to be sent to. Others label it from the perspective of the device connecting to it. So TX is where you connect the line your sending bits from. To me that’s wierd because, to others it’s what they expect. There is no standard and the result is you end up hooking it to an oscilloscope and see which line bits are being sent from. Then you use the scope to figure out all the settings. If they don’t transmit in power up then… Frustration ensures
