    Getting ready to manufacture something and need advice for detachable battery pack.

    Well, we need to make it waterproof and this method is way of getting power from the batteries. I'm using one of these. Can I draw power from the micro-USB part? https://www.adafruit.com/product/1904 I thought that's what the 5v and ground pins were for. Sorry, I'm not sure how to explain...

    Need to find a cheaper part than this: Micro USB charger board

    I'm not afraid to modify it, but I'm trying to find one without that connector piece in the hopes of finding a reliable one for less. Thanks. Ian

    Getting ready to manufacture something and need advice for detachable battery pack.

    Hey guys! I've never manufactured something before and this is only the second other thing I've invented, so forgive me, I'm learning still. The device I'm working on has to have a rechargeable battery pack. We have the rechargeable batteries, the micro-usb recharge terminal and the casing...

    Should I be able to use this battery with these LED's?

    Hello all! I'm working on a project with these LED's and was curious if I could use these LED strips: https://www.superbrightleds.com/moreinfo/top-emitting/outdoor-led-light-strips-weatherproof-led-tape-light-with-18-smds-per-ft-3-chip-smd-led-5050/1622/#/attributes/49 with this or something...

    Can I split an 8 AA battery holder into 2 packs that still generate 12volts?

    Awesome, thank you! So I'm drawing 12 volt Current from the other one. With these I would wire it up like this and get the same amount of current? Thank you! (-)-----(+) [AA] [AA] [AA] [AA] [AA] [AA] [AA] [AA] (+) (-) (+) (-) Appliance

    Can I split an 8 AA battery holder into 2 packs that still generate 12volts?

    Hey guys! I'm building a project that needs to conserve space and do so by spreading things out. I have a Plastic 8 AA battery holder that converts power into 12 volts. I'm trying to see if there is any way that I can take it and convert it to two 4x AA battery holders but still generate a 12...

    Trying to power strobe bulb from wall fire alarm.

    Greetings! I recently purchased two fire alarms like you would commonly find in a building. I purchased these for the strobe bulbs inside and the alarms, but the alarms ended up being way to big for my project so I purchased two smoke detectors and ended up using those alarms. My current...

    Are these buzzers just like the ones found in a smoke detector?

    Thanks guys! I'll post some photos of the alarms I salvaged from some smoke detectors. They have a ground wire unlike most other alarms I've seen on the internet.

    Are these buzzers just like the ones found in a smoke detector?

    Hello! I was hoping to find out if anyone has any experience with these types of buzzers and if they are as loud at beeping as a smoke detector is? Do they produce a buzzing noise, or more of a beeping noise? Thank you...
