As per the title of this post , I share a tutorial to make a charger hp / portable phones that term cool Powerbank : D.
Starting from battery sony ericson K510i already convicted ngedrop constantly looking for ideas to make my brain without having to buy a new battery .
Because many rechargeble battery ( rechargeable ) unused tamiya former had thought to use it .
But that desire is gone when I saw the long battery RC untouched .
Finally, the decision falls on the RC battery is 700mAh capacity of approximately 1.2 volts . More practical than tamiya batteries are still pritilan : D.
RC amounted to 8 cell battery , so the total is 1.2 volts x 8 = 9.6 volts . And 700mAh x 8 = 5600mAh . Or 5.6 Ampere . Wow . . .
Why even counted - itungan yaa ? : D . .
Do not let me know papa mama was little . . : D
The question How do you let the battery aka RC Remote Control ( not yellow, you know that box ! ) Can ngeces hp ?
Not clay deh hp charger adapter directly from the electricity it says input : 100 - 240VAC ~ 100mA , 50 - 60Hz
Output : 4.9 VDC ~ 450mA
See the output , because that's all we need is 4.9 VDC ~ 450mA .
Compare with RC battery 5600mA or 9.6 VDC ~ 5.6 A. Much larger RC battery right? Imagine if you directly for hp charger , your phone will be damaged even fire ! ! Eat do not mess with electricity if you do not understand ! ! : D
Some there are 3 RC battery cables red , blue , black . Just use the same red- black .
And what next? Yes we turunin voltage of 9.6 VDC 4.9 VDC Being let's easy 5Volt DC .
Why not 3.7 volts ?
That's the capacity of the battery so we used above but not too big hp power ic jebot later : D .
I use the IC AN7805 Regulator LM7805 or other important or 7805 .
Since my K510i hp charger adapter generates the amperage 450mA for ces hp, then I use LM78M05 Regulator IC. But given MC78M05C electronic stores.
Never mind the important 78M05, letter manufacturer code in front.
If your adapter hp more than 500mA use only the 7805.
Skemannya following:
LM78S05: 2A
LM7805: 1A
LM78M05: 500mA
LM78L05: 100mA
Code 05 indicates the voltage was lowered to 5volt.
There are LM7809 means 9volt and others. Minimal input 7volt 7805, if less than 7volt not be stable. Maximum input to the IC 78xx 30volt battery so it could still use a 12volt motor 5A. But do not forget! Put the heatsink so that heat reduces the IC, if the need for a DC fan. If it does not heat the IC can make fried eggs sunny side up half-baked ... : D
Now prepare the materials components:- bateray RC 9,6Volt
- saklar
- IC Regulator 78m05
- D1, dioda N4002
- C1, capasitor 100uf/50v
- C2, capasitor ceramic/milar 100nf , kode : 104
- R1, resistor 180 ohm
- D2, LED 2-3volt
- PCB Matrix
- Port USB Female
- Heatsink
After that raft components on the board pcb with circuit schematic flow matrix as below.
Note the installation of D1 and D2 do not reverse. And also do not be reversed C1!. Once done tests with a multitester or avometer.
The appearance got me:
After that my raft back into a flashlight by adding 2 leds, the result is like the picture above.
UPDATE 10 Februari 2014 :
Because a lot of comments asking, then today I decided to update this post.
below there are a series of schematic drawings which have dimodif to be like the picture at the top of this post (no additional DC Jack and 2 LED lights as a flashlight)
Here's his statement: R2 = 180ohm-1K (it is up to you how much love, the less Ohmnya the brighter lights)
D3 & D4 = LED Lighting White color
As the DC jack connector between the Adapter 10volt battery POWERBANK
switch
Can you create a physical form at will, I just made the above scheme groove.
If there are not clear can be asked to comment below.
