    Hi, I wanted to know how I can send data (voltage and temperature) from multiple wemos d1 minis to a raspberry pi 3 running InfluxDB. If this works I want to send this data to Grafana. Unfortunately I know nothing about things like that and have nearly no clue how to do that. I managed to...

    Hello Everyone - My 2002 Jeep Grand Cherokee is not driven very often and the battery has had to be replaced twice since 2016. The only drain that I can think of is the alarm system. My question is whether I can simply disconnect the cables and leave the battery in the car - or should it be...

    I have some seasonal decorations that have your standard 110v wall outlet plug, but my apartment doesn't have any outlets on my patio. I was curious as if there would be a way for me to splice some sort of battery power where the plug is. Would I need some form of transformer since it runs at...

    Hello everyone. My gf has this funky house. And behind this old retro furnace I look up and see this. I have no idea what it is. But seeing a recharger makes me think if this is an old igniter system. I did measure the volts on one of the battery it was reading 2 volts. (but it on...

    I have an older cordless Makita circular saw (model: BSS611) I bought with a set of Makita cordless tools. One of my batteries died and I bought a newer 4.0 amp battery (the 5 amp batteries are still quite pricey) and a new charger (model: DC18RC) because Makita says the 4 and 5 amp batteries...

    I own a 2005 Camry that I bought new. The original battery lasted me 7 years and one day I went out to start the car and --nothing happened. Called auto club, service tech said battery lasting that long was remarkable, so he got me going and I went right down to a local chain repair shop and...

    I'm building my own home and so far I've been totally off-grid with a solar powered battery setup. I'm looking into getting connected to the grid because I can't store all of the power I make and also can't run power tools for example because they draw too much power. I'd like to be able to...

    This project is being developed due to a dilemma I am facing with my co-tenant. There was an agreement in the past where we divide the utility bill for electicity 25/75 (I being 25), since I was a lower power consuming commercial unit. Now he's asking for more and for me it's not worth it for me...

    Where should batteries and inverter be mounted (indoors or outside)? I read that while batteries are charging they emit a flammable gas. I also read the inverter may create a spark. This sounds like a dangerous combination. How far away should the inverter be mounted from the batteries to avoid...

    Feeling stupid and was hoping someone might know the answer. The 6 lights pictured below are each normally meant to be directly hooked into a 9 volt battery and have a resister built into each one of them. An odd project requires me to wire the power to them instead. Question #1: Can I safely...
