A couple of times a year I send in a bunch of PCBs. As usual I combine multiple designs and have them delivered express. That sounds a bit expensive but when ordering about 4-5 designs the cost is almost the same as the other snailmail options. I also make sure I send...

Designing a PCB businesscard seems to be the go-to for a hobbyist electronic engineers. Most people design either a passive PCB, USB HID/MSD device or battery powered LED frenzy. Uptill now I haven’t seen any cart that has a RFID, not even regular paper ones. As...

Today I stumble across a neat/new feature in Eagle I haven’t seen before. Prolly in there since early versions 7, but at least it is present in version 7.5.0 (current version at writing is 7.7). Some PCB manufacturers will accept panelized PCB and you can save a...
