In this DIY project, learn how to build a simple 1.5V battery welding machine at home. This easy-to-make tool is perfect for basic soldering and welding tasks. Using just a few materials, create a ...

Watch as a simple 1.5V battery is transformed into a DIY welding machine perfect for soldering wires. This genius idea brings a new way to handle small welding tasks right at home.

The circuit uses only an AA or AAA 1.5v battery (1V to 2.4V). The charger is composed of simple oscillator, a rectifier, and voltage regulator. This is similar to the Joule Thief circuit. The feedback ...

Here is an interesting circuit to generate stable and secure 5V DC (at 200mA max) from an ordinary 1.5V AA sized cell. At the heart of this circuit is IC1 MAX756 from Maxim, which is a CMOS step-up DC ...

The Ground is odd, but the +/- 1.5V appears with your image that it makes a total 3V circuit/battery, but the board only needs 1.5V to function. It's sort of like wiring up batteries for a golf cart.

But the inability for traditional NiMH (nickel metal hydride) batteries to reach the voltage of a single-use alkaline battery at 1.5V or even maintain their 1.2V level for the operating life of the ...

A: Within the primary battery systems the most common are the 1.5V alkaline batteries (AA, AAA, AAAA, C, D, 9V). These are widely available at retail and are relatively inexpensive for the ...
