    "Portable" system to output power from solar to a notebook

    To provide you a more in-depth explanation of your requested photovoltaic panel system. I need to know:The magnitude of solar radiation available for energy conversion in your geographical location.

    "Portable" system to output power from solar to a notebook

    Very well... I am shameless which supersedes embarrassment. Make and model of your laptop. Clarification is needed. From this post I have to guess that you wish to plug in your laptop as you would in your home through a power outlet correct? As far as solar panels I would suggest flexible solar...

    Canon i865 inkjet printer not powering up after refurbished print head installed

    Well then you have just proven you can swap out good known working boards with no problems. Refurbished boards must be reset because they're wiped clean so to speak it's stated in the service manual. But in order to do so it must be able to power up and if not then you have purchased a defective...

    No! he's talking out of his behind! (I know... I possess a doctorate in that field) Referencing your link (paraphrasing) you're dead printer head logic board if the power supply becomes defective it affects the fused 3.3 volt microprocessor logic lines signals. They talked to talk but don't walk...

    Need help about switch power supply circuit

    I was curious I've never seen an RMS voltage stated as 150vac.Just curious? I understand based on distribution load demand that value may swing drastically minimum to Max. I meant no offense. It really doesn't matter. No answers needed. It could be 10kVac ohm's law Or any laws that govern is...

    Fire alarm using a PTC as a sensor.

    "An operational amplifier must be used."That sounds very much like a class assignment.Is this school work? If not. High temperature sensing is a very good indicator of a fire... Unless of course you have a heater set at 60° c. :rolleyes:
