In this instuctable ill show how to make handpowered led torch from servo motor

The basic principle behind this project is servo acting as a generator when given mechanical rotation which is similar to bicycle dynamo

Step 1: Materials Required

servo motor

small cube with lid


super glue

Step 2: Fixing the Led

make a hole on the cube so as to hold the led and passage of wire

Step 3: Servo Connections to Led

servo is connected to led by the 2 terminals present in both ledand servo motor

connect the led to servo and just give a check by rotating the motor shaft clockwise and anticlockwise

Step 4: Gluing Up

using super glue base of servo is attached to back side of cube

Step 5: Torch Is Ready Just Give a Little Rotation and Its Ready for Action

Step 6: Full Video of Making the Torch

<p>sorry nice try bit no.1 you kill the led verry soon.</p><p>2 its a flash not a constand light</p><p>3 to smal to handle </p><p>i would put 1 item on it : Z -- you see here the letter Z, thats our paperclip bend it almost like that but with a Vertical LINE not scuare. put a piese of tubing on the side you turn the led on and you can CONTINU have light. (but place a resistor of 500 Ohm and see how bright it is then go lower in Ohm`s by 100ohm every time (not lower then 200\300ohms</p>
ya ill try to improve it....
<p>and dont get me wrong friend,</p><p>its amazing in its simplicity and looks,but the name was what me akted to respond.</p><p>as i say ,nice</p>
<p>(related subjects) if we integrate rectifier , capacitor , modulated LED drive&sup1; with current control&sup2; ((then it's not sure if it's all worth it ... unless we succeed to find the working configuration for particular combination of hardware -- servo , LED , ...))</p><p>&sup1; <a href="https://www.instructables.com/id/555-Timer/step7/555-Timer-Astable-Mode-Duty-Cycle/" rel="nofollow"> https://www.instructables.com/id/555-Timer/step7/5...</a></p><p>(the PPM drive is likely easier to fine tune for MOS-FET and vice versa than PWM -- about&sup1;)</p><p>&sup2; <a href="http://forum.allaboutcircuits.com/threads/can-someone-please-explain-what-this-circuit-does-or-even-tell-me-the-name-of-this-circuit.126501/#post-1032308" rel="nofollow"> http://forum.allaboutcircuits.com/threads/can-som...</a></p><p>(there are not too many good precision high current limiting circuits -- about&sup2; -- though all above may need modifications to fit in to new needs)</p>
<p>anyways nyc video.......</p>
<p>New York City viideeoo nana nan naa nan naa naa naa naa naaa . . . Sempre assim, Em cima, em cima Em cima, em cima Sempre assim, Em baixo, em baciu Em baixo, em baciu</p><p>(todays mood , muhahaa)</p>
<p>very good initiative for servo generator use</p><p>(i guess i have some floppy drives lying around F;i)</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/RYCWY52yVVQ" width="500"></iframe></p>
<p>When your Led will burn (soon), add a resistor to the new one, it will last much longer ! </p>
<p>ya sure ill try it out</p><p>anyway thanks for ur suggestion..</p>
<p>Let me collect these materials. Then i will do next things.</p>
<p>good...go ahead</p>
<p>I will try it again later. Thanks for such nice tutorial.</p>
<p>OK i got it.</p>
Add a capacitor and a single pole, double throw (SPDT) switch and toggle between charging the cap and using it as a temporary battery.
Ya surely ill try to modify it
Ya sure sir I will try do it on my next instructable
