The battery in my Lenovo laptop were slowly losing charge. Remaining capacity was 69% (good score after 2,5 years) but I need the really long battery time while travelling. The battery statistics according to Lenovo power utility:So, I bought some...
The Bio-Metric Time Clock features a 4.3" color touchscreen display, 3G cellular capabilities, silicon fingerprint sensor, accelerometer, and GPS. This project has a custom PCB to provide the functionality needed for the features of this device...
helloLets all put our heads together and make this true.I have sketched a few ideas on what this printer should do:-create traces - this could be achieved with standard copper strands from electric cables - flexible enough...
So I took my bicycle out to my parents, about an hour ride and I noticed that it's quite embarrassing as a tinkerer not having my own arduino based bycicle computer. I've looked around the web and could not find something satisfying to start with, only...
DESCRIPTIONA gradually improving attempt to make a useful pcb mill out of a printer and other assorted garbage, with a minimal budget and no fancy tools. It works!, but let's see how much better it can be.DETAILSNOTE: This project is gradually improving....
I cut the pcb just above the bottom of the zig zag pcb antenna, remove the copper going from the signal line and ground, then scap the soldermask off near the passives, that is also a grounded point.On the revers side scrape off the soldermask...
I thought I might as well share my thoughts on some new stuff I got from SparkFun.First up: the 50 watt soldering station. Apart from the metal dome for the brass sponge in the iron holder being loose, it's a solid iron. Adjustable temperature, fine...
