Thermal Tweeter fail, that’s all folks @dangerousproto

It looks like Thermal Tweeter has come to an end. After 15 rolls of paper the printing is light and the paper isn’t feeding properly. We tried adding some extra delays in the software, but even at 4 seconds delay per line the problems still happen. It’s supposed to have a life of 30 miles […]

Partlist Wednesday: Ceramic capacitors

Every Wednesday we highlight a component from the updated partlist. This week: surface mount ceramic capacitors. Ceramic capacitors are cheaper than aluminum and tantalum SMD caps, but come in smaller values. Typical values are in the pF to 1uF range, but we’ve noticed some 2uF+ ceramic caps at Mouser recently. Most have a maximum rating […]
