    Hand Sanitiser Dispenser Circuit

    Sir Waitingfor Here are my mechanico/technico perceptions from your pictorial data as being provided: That the units initial activation is being dependent upon an approaching hand establishing reflectivity of a LED light emitte source as per my markup, reflecting onto a sensor *** to then...

    Lithium ion polymer battery: What is the 3rd (yellow) lead? what can I use for a replacement?

    . Sir Midatlantian . . . . My suspicion is this: That the red and black be assigned to the + and - battery connections, with the yellow being a sense wire to provide corrective info to an off board charger. Typically the sense mode will be provided by variable resistance provided by a small...

    Can anyone identify these components? They are SMD

    It also reminds me of a SM profile of Wee-inductor. Additionally, subject the unit to a neodymium-yum-yum-yum magnet placed atop it, and see if there is being any "pull" to a core material. 73's de Edd

    Are there any alternative to epson ic A2098, C6082?

    . Sir ngzek . . . . . It would be nice for you to have given the model of the Epson printer to research. Strange that you are assuming the devics to be integrated circuits I am suspecting them just to be common bipolar power transistors. Those numbers are akin to the common assigment used...
