    A lightweight, simple Li-Ion charger for running off DC.

    I bought cells from my supplier before and he said matched cells are possible, albeit little bit more pricy. Also, last time he sent me a test sheet which I double checked with my mulitimeter and they were pretty close, I only remember one cell which had quite high internal resistance out of 100...

    A lightweight, simple Li-Ion charger for running off DC.

    Hi, I want to build my very first li-ion charger, so any help and tips are much appreciated. I've only worked with digital circuits, so my experience in this area is close to zero. I have a 5s6p li ion ncr18650b battery pack that's going to power my portable desktop. I'm planning to use a...

    Datasheet question for CCD linear light sensor TCD2711DG

    Thanks, this is both a good thing and a bad thing: The number of lines that I need to scan increased significantly as my DPI of the line itself increased. 2700DPI is pretty high given that it is a tri-linear ccd sensor not bayers style sensor witch each pixel having all three RGB pixels. One...

    Datasheet question for CCD linear light sensor TCD2711DG

    At the header of the datasheet(you can google it, I wasn't sure if a datasheet counts as an ebook), it says 600DPI sensor. However, it has 7500 pixels per line(7500*3 for RGB technically), and sensors are almost 70mm long. How does this translates to 600DPI? By my calculation, 7500pix/70mm =...
