Made it into a business card as you can see.
- rexreed 4y agoI'd love to make that as well or find a source for it. Curious as to costs to manufacture and ease of reproducibility. Any tips / pointers / guides?
- testmasterflex 4y agoCan’t find the tutorial I used but here is one https://reddit.com/r/electronics/comments/efz9xf/my_nfc_powered_blinky_business_card/ https://reddit.com/r/electronics/comments/efz9xf/my_nfc_powe...

- rexreed 4y agoI found this one: https://www.instructables.com/PCB-Business-Card-With-NFC/ https://www.instructables.com/PCB-Business-Card-With-NFC/ Looks closer to yours? Not sure how you did the 24k gold part tho ;)
- testmasterflex 4y agoYes, that’s the one I used afaik. The gold is one of the materials you can choose to plate your copper on the board at manufacturing. “Enig”. Increases conductivity but also looks sexy :D I think every board was $8 on MOQ.
- rexreed 4y agoawesome - thanks - going to pull this together!
- seedboot 4y agonow use that energy to mine bitcoin and you'll be rolling in ~~money~~ decimal places before you know it!
