They keep hyping plastic recycling issues like it's politically correct. https://www.theguardian.com/us-news/2019/jun/17/recycled-plastic-america-global-crisis If minor low cost changes are made to plastic containers beforehand it may be easier than they think to make recycling profitable. Most industrial separation processes don't have the luxury of designing what is going to

The aaa alkaline batteries went out on my tv remote. I decided to use my NiMh UBL aaa batteries. 1100 mAh. They are currently showing 1.31 volts. And they work ok in the remote as is. My charger is the manual type. It charges that type at 150 mA. I want them fully charged since they are 1.2 volts versus 1.50 for the alkaline. I would like to know how much longer to charge them...

My workshop stuff includes many unused phone cables, discarded when their respective phones were replaced over the years. I'd like to use these for general wiring around the house/garden/garage/workshop. Can anyone recommend a cheap socket to make interfacing easier please? With breakout leads to either plain (and thicker) wire ends or screw blocks or similar? Terry, East Grinstead, UK

I bought this thing. It has setting to adjust but it does NOT maintain anything like a set temperature. I left it on one night at the 300 setting. When I woke up the next day and say that it was on, I noticed that the tip was slightly glowing. https://i.imgur.com/qhM1Ymo.jpg https://www.ebay.com/itm/Electric-Soldering-Iron-Gun-Adjustable-Temperature-60W-Welding-Set-Tool -Kit-110V/37

My TV remote for a Westinghouse lcd tv is acting strangely. The power button generally works. The channel button will go on channel at a time or go thru all the channels. Sometimes hitting one button will result in another function occuring. I tried shutting off all other devices near the tv. Another remote for a radio has a power button that works on the tv. I changed the batter...

I could use some feedback. I think I soldered on the right side this time. https://i.imgur.com/vTV4Qwv.jpg https://i.imgur.com/SNdSgdJ.jpg https://i.imgur.com/gLIvVCQ.png The circuit was working and I made adjustments to a pot. The pot ranged from 0 -> about 4400 ohms. I got the circuit already pre-made and it worked ok indoors. I forgot to record the resistance before I st

I bought my first Arduino UNO R3 kit two weeks ago (the Elegoo Super Starter kit) and am stepping through its tutorials. In parallel I'm trying to learn the basics of its C++ based programming language, but that's proving a struggle. I'm impatient to use Arduino on my own projects so I will take a 'copy/paste/edit' approach. It then becomes a matter of finding sketches that cover a particular ...
