Electricity is important for us. But sometimes we need electricity in emergency, like power outages, emergencies, camping, etc. With this inverter, we can use Car / motorcycle battery. This can increase the electricity from 12V DC to 220V AC, and this can turn on Light bulb, Phone Charger, and small consumption device.

OK LET'S MAKE IT!!!

Step 1: You Need This

• 2 Pcs TIP31 Transistor
• 2 Pcs 15ohm Resistor
• Transformer with Center tap, 1-15 Ampere (I use 1 amp, but it's have a small voltage output. I recommend you to use 5-15 amp transformer)

Step 2: The Schematic

Simple, Anyone can build this inverter.

You can build this inverter less than 30 minutes.

Step 4: Thanks for Look My Works!

I hope you can make better than me, HAPPY MAKING!!

<p>This circuit runs at 11Hz, and power delivery is terrible, not even a sqaure wave.</p><p>Frequency can be found as f = R/1.45</p>
<p>Yes, and thinking about safety, it could kill your just laid out as it is. Especially if you go for a higher power transformer. One high voltage lead in each hand and you would be jumping about!</p>
i suggest you to make the case for more safety. Thanks for look my works
<p>This circuit is basically a free-running oscillator and I doubt its frequency is anywhere near 50 - 60 Hz. I would be leery of connecting it to anything requiring a 50 - 60 Hz power source.</p>
thanks for look my works. <br>
<p>What is the wattage rating of the resistors please?</p>
1,5 watt
or bigger
