Tubular Battery MaintenanceBattery maintenance is very important when we use Home inverters. Generally Tubular batteries are recommended due to its high efficiency and life span. Various makes and types are of batteries are available in the market. . Tubular batteries are recommended to backup UPS and Inverters where environmental conditions are tough and ambient temperatures are common. These are capable of long hours of backup and the life period is around five years. Battery is the backbone o.......

I am still lingering around flyback transformer and never start my tesla coil design since i am too absorbed and keen to know how does the flyback transformer work. For your information, before i got to have the ferrite c cores from the original flyback transformer from CRT tv, i have purchased four ferrite rods from Ebay as i ve planned to made them into my own handmade ferrite core or frame. As the rods were still in my room and i ve got nothing to do with it therefore i decided to resume to t.......

This circuit idea is certainly not new, but when it comes to making a trade-of between using a small, short-circuit proof transformer or a capacitive voltage divider (directly from 230 V mains voltage) as the power supply for a fan, it can come in very handy. If forced cooling is an afterthought and the available options are limited then perhaps there is no other choice. At low currents a capacitive divider requires less space than a small, short-circuit proof transformer........

LM386 is very fun. It is a multi-purpose power amplifier 8 pin chip designed to amplify small power. I ve used it to amplify small signal from my crystal radio receiver and it works marvelously! It can even power up an 8 ohm speaker, to the sound level of mobile phone speaker. This amazing chip i bought from Ebay for GBP 3. 17 , and got ten of them. To use it as crystal radio am.......
