6V and 12V batteries battery charging circuit Charge Current is 0.3 A and 1A able to charge can be selected. Binding to have protection against battery reverse polarity. Float charging reverse connection, Charging status indicators and is equipped with Float charger the Float charger 14.7 V 12V battery is fully charged, the charging case feature…
The operation of a transistor amplifier for beginners. Integrated transistor amplifier from a mediocre competitors an example of how cheap it is superior, actually. I found a diagram in a foreign forum, I wanted to introduce a quite simple and low cost circuit. low-cost amplifier schematic Quite an old history in 1974 schema and extends…
Once AD161-AD162 I had an experiment with pair. I still use almost every day. At first I didn’t like the sound, but I like listening to. The frequency of particular speech sounds very clear and is understandable. Quite a while (probably has been for eighteen years) and two ad162 ad161 a pair of them in…
Lead acid battery sulfate contaminated plates designed to solve. Currently sold as the product version are also available. In this study, a similar application to them. It seems stuck at length information is the easy way to give the site links I found only the schema, run off their own pcb design I’ve done on…
I don’t use a soldering iron too expensive for everyday use. 30W is sufficient for mounting those, but it’s hard to solder thick wires and chassis. In these cases, 40W soldering iron is inevitable, it makes for cheap of this stuff deteriorates in a very short time. 40W soldering iron and a middling one of…
the led with a single battery would be interested in a while. Find a suitable circuit and a couple of candle left to do puts, instead I thought we could take advantage of. The place even over the land of both water PCB SMD SMD because let’s face it now it’s designed as something called…
