Remote control, radio, camera... In our daily life, some e-waste is often generated, and used batteries are one of them. But do you know? For ordinary alkaline batteries, people usually think that they will be discarded after the power is insufficient. It is not known that the average remaining battery capacity of each alkaline battery can reach 400 mA. If they accumulate a lot, they can still play a big role.
1500 used batteries constitute a mobile phone charging station
Recently, Thailand's beverage company Vitamilk has creatively built a free mobile phone charging station using waste alkaline batteries, not only for smartphone users to charge for free, but also intelligently conveys the concept of adding energy to their products.
In this mobile phone charging station consisting of used batteries, a total of 1500 batteries are included, and all the residual power is combined to fully charge up to 140 smart phones, providing a total of 830 hours of talk time. After Vitamilk placed it on the side of the road, it provided 3,328 hours of talk time for passers-by in two months. It was not only economical and environmentally friendly, but also solved the problem of low battery power for passers-by, and it also achieved good results. Product promotion effect.
Wood lathes can be used to create functional furniture components, beautiful decorative wood projects such as candlesticks and bowls, or even toys such as tops and yo yos. These machines range in size from hobby models that fit on a work bench to large industrial-sized machines weighing hundreds of pounds, but they all share some basic elements. Here are some instructions for using these unique machines. For those in the machining and turning crafts, it`s common knowledge that the Industrial Revolution had a significant impact on the evolution of the lathe and additional machine tools. As humans began developing tools and technology, honing new skills, and began more efficient ways of production, different power sources started to become standard. Motors now required electricity, meaning the conventional way of operating machine tools by human touch was being phased out as more and more machinists were [turning" to automation. But before automation and metalworking became regular practices in the machining world, there was woodturning and thus, wood lathes.
