Hi all,
As a homebrewer, I use some devices (iSpindel) to monitor fermentation parameters.
I also have small wifi relays, DIY made by someone else, which transmit measurements to my brewing software, and also display the latest ones.
These relays work very well but have a small drawback: they...
Attached image of Coconut cutter product electrically operated mains supply(AC). Can it also work with Batteries (DC)?
Thanks & Regards,

I got this online to seal polybags. The wire heats up and seals up the bag. But reality is it fails pathetically because it's too thin and doesn't heat up adequately even on brand new 6 AA batteries.
I wanna save bucks because I have already bought it.
Can someone guide me to give it more power...
I am pretty much new with this adapter thing. I bought an adapter today with a 9 V rechargable battery. I tried my multimeter between the output and found something interesting. The output voltage is 5 volts on the 9V port. But when I am connecting the battery and turning the adapter on the...
Hi, I'm new to electronics and I've been starting a project of my own which is a charger (since i though i should start first at power electronics since its all about electricity before pursuing switching electronics or automation). I had previously created a charging system (using the li-ion...
Hi all
I am in the process of designning a battery measurement and balancing system I was thinking of using a TI BQ76930, I am following the design guidelines found on pages 4-7 (**broken link removed**). The main issue I am having with this design is identifiying the following properties I am...
Housing batteries in an enclosed aluminum tube. Batteries will need to heat up the housing to 80-100 decC for 40-50 minutes. Dimensions of housing are 2 inch diameter by 24 inches long. Question - Is there a battery that could generate enough heat over that time period and fit in the housing...
Hello
My question might seem very obvious but i never really understood why... Too much power is being wasted during charging because of this internal resistance, there must be a logical explanation for this and i need that to know.
I am not looking for technical answer instead if you could...
Hello
I need to clear some doubts about solar power.. I will write down my theory please correct them if i am wrong.
I must tell you that i have absolutely no knowledge of solar power system. I have tried google but couldn't understand how solar panals are calculated and how many batteries and...
Hi,
first of all let me say that I am a software engineer and have no experience in electrical engineering, so some of the below questions may sound stupid. I am learning electronics for some of my side projects and would need a little help!
I am powering up 13 vibration motors (28822) from a...
Hi, I'm working on a battery to power my continuous 6kw DC motor. The max amp for the motor is 200 and it's max voltage is 60. I want to use 14 3.7v 15ah cells to build a battery, but I'm confused about wiring in series or parallel! I'm unsure how to wire it because either way makes my...
