Simple BUT Inefficient circuit! Much of the 3.7 volt battery's power is wasted as heat from the BC547 transistor and the two 10k resistors. A more efficient, yet more complex, circuit would be to use a buck converter to drop the 3.7 volt battery to 1.5 volts .
Projeto muito bom ! Reaproveitamento de Baterias e também de pilhas Recarregáveis de Notebook. Faltou somente colocar um carregador USB para alimentar as Baterias para o Funcionamento do relógio.
A better idea would be a USB input to charge batteries (rechargeable) and thus interconnect them to the clock, as well as remote controls, of which there are many in homes.

Nice 👍👍
When battery gets down how it will charged. You would have added a charging circuit or mobile adopter to battery in parallel.
_Bravo._

Use LM317T (input dc 3-38 volts) as voltage regulator and you have your 1.2 or 1.5 volt out.
I too used this circuit but my lithium cell wad drained within two days

how to charge battery?
платка 4056!
cọc duoc khg anh
Niby mądre ale ta baterie też trzeba naładować więc trzeba dołożyć moduł ladiwania
🎉🎉🎉😊😊😊😊😊❤❤❤❤❤❤❤
ใส่วงจรชร๊าตไฟไว้(ต่ำเติม/เกินตัด)❤❤❤❤❤
10 rs का cell 1 साल जाता है
AMS1117 1.5V board
Quero ver recarregar essa bateria 😅

If you put a new 1,5 AA battery,will be cheaper and easier
100% correct
أسان سا بنا کر بھیج دو کیونکہ ادھر پرزے نہیں ملتے
uma pilha sai mas barato. vai vendo kkk
SHOW
ये तरीका गलत है बोल के आराम से वीडियो बनाओ फिर से रजिस्टर कितने का 10 om के लेना हे क्या और watt का ये नही बताया
All impotant things I show in the video
@@AryanExperiment-se4wr रजिस्टर की वैल्यू नहीं बताई
क्या भाई रजिस्टर का मूल्य बता रहे हैं। 10k रजिस्ट्रार 1/4वाट का। आप ठीक से देखिये.
