    Energizer CHPROWB4 Project

    The part # you gave seems to be a bundle of CHPRO charger plus 4 batteries. This charger (linked below) has the AC mains wall plug directly on the rear of it, unlike some that have a separate AC/DC adapter (usually at 12VDC). http://data.energizer.com/pdfs/chpro.pdf Because of this, it will...

    Li-ion battery pack

    Yes the pack will need a protection board to keep it from draining too low, and being a drill it will need to be beefier than some, able to handle above the stall current the motor is rated for @ target voltage. Typically Li-Ion drill packs have either a PCB with a large copper area and vias to...

    Something zapped it

    I doubt it's just fuse(s). With one side still working, I would suspect the output transistor(s) for the other channel are blown. It is curious that the speakers are blown unless someone was using it while you were away.

    CB/ballast on a OTTlite

    What I would do is mount a piece of plate aluminum in it as a heatsink, where the CFL tube was, put 6 x 3W LEDs on the plate, and run them at 1W each as two parallel series of 3 LEDs each, powered by a 12V (~1A rating is common and plenty of margin) switching wall wart (AC/DC adapter). This...

    Li-ion battery pack

    I have nothing against reclaiming old tools, have rebuilt the packs for an old Dewalt 14.4V drill I have, but stuck with NiCd, so the charger was still usable. Even so I wouldn't have done it except for that drill coming with a snakelight that's very handy and that I've converted to LED. I use...

    Crock Clips

    Try contacting the developer, asking for the old version?

    Li-ion battery pack

    What you are doing makes no sense to me. You're starting with a weak 12V drill, might weaken it further using only 3S cells so nominal voltage is down to 10.8V already, but apparently feel a lot of extra weight (low weight is the only reason to pick a 12V drill over 18V in the first place) is...

    Led resistor types

    Although the type doesn't matter, it is good to over-shoot the needed wattage rating for lower thermal density, and if using a PCB, to leave long(ish) leads so less heat is transferred to the solder pads.

    18650 Under voltage protection

    Umm... :rolleyes: I wonder if the reviewer meant batteries or fingers?

    Hi all, from a different tradesperson.

    I don't know the regulations there, but suspect you will have an easier time if you use already-certified external wall wart or brick style mains AC-DC adapters to power them, so your unique design starts with an Extra Low Voltage DC input.

    Rewiring Power supply. Noob question

    You list 6 HDD ( 4 x H + S x S), but earlier you implied support for 3 HDD? HDDs can have higher spinup current than that listed, but generally one lead will support 3 HDDs, especially if they have staggered spinup. You did not need to loop the wires in the 24 pin, it doesn't really do much...

    Problem with bringing internet to entertainment center

    IF you have a model TM1602 modem (manual linked below) then you only have one lan port on it as shown on page 18. In that case see page 30 of that manual. It states quote "I have two computer connected to the telephone modem, but only one can get on the internet. Check your cable company's...

    Problem with bringing internet to entertainment center

    WHAT MODEL MODEM? That is literally the only thing we needed to know and still do. If I am understanding correctly, that you used to have DSL, but now do not have DSL, have only cable internet instead, then they did not splice into the phone line. They ran a coax cable to your premises, to a...

    Help needed identifying onboard fuse

    Determine where it is in the circuit then see if the following document is helpful. It seems the Siemens now goes under the name Daikin? It has diagrams for multiple models with fuse current and you'd pick a voltage rating above that shown for that part of the circuit...

    Problem with bringing internet to entertainment center

    TLDR: What is your modem make and model #? Do you have DSL or cable internet? What model of modem do you have, this will tell us even more than the answer to the above. Either you have coax cable coming from your outside junction box to the modem input, if cable internet, -OR- you have a...

    Cassette Deck Help?

    You will have to take it apart and see if the belt is moving both pulleys it's on, or if the motor is stalling, or pinch roller not staying on, hardened rubber or broken spring, etc. Is the player worthy of buying parts for? You might find something that works, cheap at a garage sale...

    Recapping pc motherboards.

    I have recapped many many different things in including motherboards. My technique and equipment may differt slightly than what others have available but the following works best for me. Don't worry too much about temperature. Unless your iron exceeds 60W, you will need every degree...

    18650 Under voltage protection

    You can get "battery protection board" shipped world-wide on eBay (usually coming from China). Will they not ship to you? A few other thoughts about this project... Some major brand 10W LEDs are fairly good quality, but many of the generics that look like the following picture, have very poor...

    Vertical ic getting Dameg every time i palce a new one

    Just quit while you're ahead. You aren't making an effort to communicate well and this just won't work. I would have locked this topic up the moment you started it with only 4 words. VERY POOR FORM.
