Since resistors are in parallel,all will consume the same voltage....so instead of using the resistors and power adapter,if I connect 3 V coin cell say 2032(since it will fit nicely within the casing),will it work or current becomes insufficient?
No,not good, the coin cell will go dead in a few days; a CR 2032 only has 100mAh; 12 small leds like that consume ~~ 12 x 5 mA, or 60 mA; so,i'll rephrase that,the coin cell will only last a couple of hours.; (they can last 10 years in a watch,because it only consumes in the micro Amp range).
You have not mentioned polarity of LED's and not clearly defined connection in series/parallel and rating of adopter also. Can't say this is informative Vedio.
Charger mat lagao. 0.22uF 400V ka polyster capacitor ke series me saara LEDs laga do. Charger ka jhanjhat khatm. Bahut achhi light hogi. LEDs front to back pairs me lagenge. Yaani 6 pairs series me honge. Direct AC mains se chalega aur ek LED dusre LED ko protect bhi karega.
You can directly light up the LEDs from the AC source by little modification to the LED circuit. Use a low value capacitor such as 0.22uF in series of all LEDs. You can eliminate the DC components by connecting two LEDs in parallel (forward and reverse). This arrangement doesn't require too many components and requires least energy.🙏
@@Vaibhav.R.Sutar45 why not? Upto 25 LEDs can be connected in series. It's even better if you use bridge rectifier by using 4 diodes. A 100uF 160 volts capacitor in parallel to LEDs to reduce flicker in LEDs. Use 0.47uf Capacitor in series with bridge rectifier at input.
@@Dave_en actually I have 0.22uF 400v capacitor and I am connecting 12 led of 3v, 0.020A in series therefore output voltage becomes 12×3=36v. So can I make 36v with 0.22uF capacitor?
@@Vaibhav.R.Sutar45 the actual voltage drop will be decided by LED. This capacitor only limits the current. If you connect two leds in parallel in opposite polarity, it will give reverse voltage protection to each other. Connect 6 of such pairs in series and use a 0.22uf capacitor in series of the LED circuit. It will be enough. No need to check voltages.
At first Li-ion battery is not 1.2 volt, it's 3.7 volt.... It's charging voltage is 4.2 volt and deep discharging voltage 2.7 volt.... Don't try to charge Li-ion battery no more than 4.2 volt... Charging with higher voltage, the battery may explode, causing serious injury.....

You Need to Mention in this Video that Which is +/- for LED Lights? & where u are Soldering the resistors330 ?...
Wow.
U gave me a better idea!!!
👏👏👏👏👏
💚💛💙🇧🇷🇧🇷🇧🇷
Clock manufacturers should learn from this expert & manufacture clocks with LED light with lithium batteries.
Niche plate ki jgah aapko side frame pr led lagane chahiye the or white colour to zyada best rehta..isme clear nahi dikh raha
الله ينور عليك ياهندسه
Adapter kiti volt cha lagel...
Need to re-do it; 4 leds only, but angled to the center,so the watch hands can be seen; gonna try that.
Which type connnecting wires used❓️
Resistance kaun sa use kiya hai...
I think 1k resistors
After a long time
Kon konse resistance or kitne watt ki led use kari h
todo bonito, pero y las agujas del reloj como se ven de noche, y luces apagadas si es de lejos no se ve ????
भाई सब्सक्राइब कर दिया
I think 12 No. Led bulbs are not required. Only 4 bulbs for 3, 6, 9, & 12 are required. Anyway nice idea.👍👍
Yes ✅
Aankade na dikhe to chalta hai, sirf kante dikhne chahiye, kanto pe simple radium patti laga lo to bhi chalta hai.
Super super nanba.

Idée très cool, les mains en l'air, salutations du Maroc
Gr8 job. 👍
Good innovative idea. 👍
Resistance value ?
सुई में तो लाइट लगाई नहीं है। टाइम कैसे पता चलेगा?
Good job👍
Very nice
resistor ka value kya hai??
Led bulb and resister power ?? Capacity of resistor and bulb watts What please tell

Wow Wonderful

Isme white led light kaafi better work karti👏🏽👏🏽👏🏽
Yapp
Dear, clock ke kanto me bhi redium lagane se achha dikhega 🤟🤟
Wowwwww👌👍😍😍
Resister valu kitna hai
Awesome, nice creation bro
Great Work
Which resistor you used what is the value and LED I din understand so please tell me ok
@mesum naqvi Its mentioned as 330E !! And what Peter is asking is the Watts of resistor, value means both Ohms &
Watts... Please answer if you know...
बहुत बढ़िया,लेकिन कोई फैंसी या स्टाइलिश नही
Yes, registan ?
Radium tape use kr lete!
Amo estad coisas
Nice work man!
.
Video ke sath sath matirial aur uski value bhi bataya Karo
beech me bhi 1 led hona tha try it
Glue koun see lagaie hai sir,?
YES
Zuba zooba....👌👌
Charger kitny volts kaa lagana hai aur resistor kitny ohm ka

Led 1.5v ?
Rezistor 330 ohm?
भाई इसको जब दीवार पर लगाएंगे तो घंटे और मिनट की सूई दिखाई भी नहीं देंगी।
Badiya... Such WallClocks available in market ?
Youayp
List the materials which is used for?
Gracias, pero en que polo positivo o negativo se suelda la resistencia? ¿Qué alambre se suelda en los extremos de los polos?
Cuando conecta el cable de la fuete de alimentación, te das cuenta
Led to dikh jaega isliye numbers pta chal jaega pr clock ke time hands kaise dikhenge andhere me ki kin numbers ke beech me h
But at night how can anyone see time?
No light in minutes second 😹

Thanku bhai desi jugar
Super.
COOL....
प्रेजेंटेशन बहुत जल्दी किया कुछ समझ नही आया। डिटेल में बताया भी नही। घड़ी की सुईया भी क्लियर नही दिख रही
Good work man very talented....
Good idea
Looks nice
Great job Sir!!

Component value should be mentioned in video thanks
Bro if we will charge lithium battery 1.2volt with power socket 12 volt in current what will happen the battery will burst or not
Bro I don't understand your language so please tell in english

wow very nice
Very super sir
Awesome
अगर आप frant में border में led strip लगाते तो सही लगता
Sahi baat hea. Time hi nahi dekhta..
Resister kaha solder kiye ,??
YES
Itni karigari karne ki
Bajae led watch hi le

Good project but ir will be EXCELLENT if you make the power supply to power the clock too...
Am with you
Happy Republic day 🙏🙏
well done
Kya bat h bhai
Thanks ........bro
Hello ...i big like this video nice thànk you..😉💯👇👇👇👇👏
Very good
Great 👍😃
Ak light clock ki suai me bhi lagana tha bhai
Wao nice
Great work

NO indication value of resistor, useless tutorial video i guess.
150 OHM RESISTANCE
Super
great
Super 👍
Very good, what is the resistance of resistors.
330 ohms...
Weldon 👍

I suppose a flashlight can do a better job.
अगर led को सुई पर फोकस करते और सही रहता
very nice/
