In this project we learn how to charge mobile phone using candle. we make simple free energy device that generate electricity when we start heating. its one of the best emergency electricity generator and free energy project.
For making this project we need some components.
Components:
Step up charging module.
Peltier module,( i use 6 ampere peltier module)
Candle,
Heat Sink,
Heat Sink Paste.
Now following few simple steps and make same.
Peltier has 2 sides. Written side is cold and opposite side is hot. We need hot side.
Peltier Red wire use for positive input and black wire use for negative input. Connect both wires with charging module.
Now apply some heat sink paste on peltier. And adjust heat sink on both sides.
And now take some iron pieces and make a stand.
Now on candle and put it on stand likes this. In cold side I put some ICE for Palter safety.
You don't need any electricity for charging mobile phone. when peltier heat then its generate automatic current and voltage.

How to convert 24v dc motor into 5v high speed dc motor
In this project we learn how to convert 24v dc motor into 5v high speed dc motor easy at home using few simple steps with the help of video and circuit diagram. for making this project we need some components.
How to convert 24v dc motor into 5v high speed dc motor
Components:
DC Motor 24v or 775motor
24 SWG Wire
Some screw dirvers
Plier (plass)
Normally 24v motor dose not work on 5 volt. because for running this motor we need high power voltage and current. its specially design for high voltage. but we convert it as our desire voltage.
we chose 24 swg because 24 SWG wire start working on 0.6 ampere.
now following few steps and make same.
High speed dc motor winding circuit diagram
1st open dc motor and remove old winding from armature.
This time DC motor wind with 16 swg wire. 16 swg work on 5.46 ampere. so its dose not work on 5v.
Now simple replace old winding with 24 swg wire winding.
Each armatures core 40 turn and after 40 turn connect wire with hook of armatures.
2nd time again 40 turn and connect wire with hook of armatures.
3rd time again 40 last turn and connect again wire with hook of armatures.
And finally last wore connect with 1st wire. like diagram.
we learn it more batter with watching video.
Video of how to convert 24v dc motor into 5v high speed dc motor:
Some basic question and answers:
Whats basic logic with wire gauge with dc motor?
basically each wire has different value of current. if we use low current wire then its work on low current. but if we use high current wire then its work on high current.
for example in 775 motor wind with 16 SWG wire so its dose not work on 5v power (mobile charger) but when we replace this wire with 24 SWG then its working very well.
How do you determine the current rating of a wire?
Normaly we calculate current rating using this formula
How to make 12v kitchen exhaust fan using 775 motor
In this project we learn how to make 12v kitchen exhaust fan using 775 motor easy at home. its very easy, cheapest, and energy saving project. for making this project we need some components.
12v kitchen exhaust fan using 775 motor
Components:
775 DC 12v Motor
12v, 1.8 amp charger
Plastic fan wings
Round rubber (for adjust motor with wing)
2 Iron pieces (for adjust fan with wall)
Some wire
in this project we use 12v DC motor. its very cheap low power and high speed motor. and best for exhaust fan.
Now following some procedure.
adjust rubber with wing
Adjust round rubber in the center of wing. ( because fan wing center hole and motor upper pin size is not same. so we use round rubber for adjust it)
adjust iron pieces with motor
Now adjust 2 iron pieces with motor. one piece adjust wit left side and 2nd adjust with right side. ( this 2 clips use for adjustment fan on kitchen wall)
connect 12v charger power with motor
Now connect wire with motor for input power ( if your charger wire is long then you can directly connect charger wire with motor.)
connect motor with wing
Now adjust plastic fan wing with motor. (motor nozzle pin connect with round rubber its perfectly fit on wing)
adjust 12v exhaust fan on kitchen wall
Finally adjust fan on kitchen wall using screw. (simple hole on wall and iron piece that adjust with motor, and adjust it on wall using screw)
we learn it more batter with watching video.
Video of making 12v kitchen exhaust fan using 775 dc motor:
we can use it with UPS.
we can directly connect it with 12v battery.
because this time electricity is a major problem. so its best alternative of 220v exhaust fan. the total cost of this project is round about 10$. you can also get DC motor form old scrap shop. then this project cost more less. if you cannot find 12v adopter or power supply then you can make it at home using this link.

How to make 12v powerful soldering iron easy at home
in this project we learn how to make 12v powerful soldering iron easy at home. you can get 1000 degree temperature from this soldering iron.
12v powerful soldering iron
its use for heavy soldering even you can sold brass very easily. for making this project we need some components.
Components:
Glow plug (you can get it form any vehicles spare part shop)
Old Soldering iron back cover.
Push Button
LED
1 K Resistor
Wire
12v power supply (we can use old computer power supply)
in this project we use Glow plug. its very powerful 12v heating device. its use to aid start diesel engine. but here we use it as a soldering iron. best advantage of this glowing is its get little power and provide very high temperature round about 1000 degree Celsius.
Circuit diagram of 12v soldering iron:
Circuit Diagram of 12v soldering iron
Connect one side of push button with Positive (+) power supply.
Now connect 2nd side of push button with one side of Glow plug
Connect Negative side of power supply with 2nd side of Glow plug.
Now connect 1k resistor with positive side of LED.
Connect 2nd side of resistor with Positive power supply.
Now connect Negative side of LED with Negative power supply.
we learn it more battery watching video.
Video of 12v battery power 1000 degree Celsius soldering iron:
Power Supply for Glow plug:
Glowing plug work on 12v power. but heating depend on current. if you provide low current then its heat-up very low and slow. if you provide high current then its heating very high and fast.
normally for soldering iron 2 ampere to 4 ampere current is enough for this. but if you sold Brass then you need 12v, 10 ampere. because brass melt in 450 degree Celsius. ( how to make 12v power supply easy at home )
Basic purpose of this project:
Basic purpose of this project is control electricity. its best for energy saving soldering iron. you can use this soldering iron with bike battery. so you don't need electricity. you can done your work using bike battery power.
