මේක හරිද වැඩ කරනවද😊
muchas gracias me resulto útil
You are welcome friend 😊
I built this circuit but the sound output is extremely low. What could be the problem?
What is your supply voltage and speaker impedance ?
Can D313 be replaced with tip41 and B507 with tip42 transistors?
Yes. D313 with TIP41C or TIP31C B507 with TIP42C or TIP32C
Alright, thanks 🙏
You are welcome..
Super broo. ...
Thank you 😊
Hi I have a question. I tried referring to the circuit above, but it doesn't work. I attached a 47 ohm resistance instead of the 10 ohm resistance at the top right, but could this be an error that doesn't work? And I used one LED for each line, could this also be a problem?
What is your supply voltage ? Not even one LED bulb is flashing or slightly flashing ?
@@hobbyelectroniccircuits739112voltage, not even one flash….
First you have to check the pulse output of NE555. To do that, power the circuit and take another new LED and 1k resistor. Then connect LED(-) to 12V- and LED(+) to 3rd pin of NE555 through series 1k resistor. The LED should blinking, otherwise the NE555 circuit is faulty or the IC may burnt.

අයියා . අවසන led 4 ඩිම් වෙනවනේ. ඇයි එ. 🤔 කහ පාට led දැම්මේ.
අවසාන LED හතර series තමයි දාල තියෙන්නෙ 10 ohms resistor එකකුත් එක්ක. 10 ohms එක වෙනුවට 100 ohms resistor එකක් දාල LED දෙක ගානෙ series කරපු කොටස් දෙකක් parallel කරල බලන්න.
එලකිරි අයියා 👍 දැන් සුපිරියටම වැඩ. ❤

What setting do I use for 12 uf? Thank you :-)

Thanks to you I know the capacitor to my 20" fan is working! 😊 That's the good news. Bad news, I don't know what that "pop" was I heard when the fan died! 😢 Any ideas?
Wereey good
Thank you..
Can i use 12v power supply to this circuit ??
Yes, you can. Use R = 1k / 1W
any calculations to determine the frequency response band?
circuit daigram ?

where is current input or output

@@hobbyelectroniccircuits73916 oms DC45 0 45
what a differen of both?

Can operate 4ohm speaker in bridge (mono) mode?
Supply voltage should be less than 9V for bridge amplifier with 4 ohms speaker. For higher voltages, IC will heats up and burn.
@@hobbyelectroniccircuits7391 thank you so much bro ☺️

Just left long comment about developer from club Vegas social casino hacking thru smart tutor, anthrothia, hacking my phones, sneaking crap in and out of my house, leaving misspelled poetry in dead people's names, pretending to be a witch. Leaving locks of red hair, pretending to be Victoria, he switched it to India feed where it wouldn't be seen as he's also controlling every comment i leave on any forum and surveying me in my home. 2 years, im sick of it.

Hello. I have one question. Have you got stereo sound from CA6928? I thought this Bluetooth IC(AC6928) is monaural. Thank you.
CA6928 is a mono Bluetooth module. If you check the L R output pin resistance, it seems to be short circuited.
I thought so. Thank you for your confirmation.
You are welcome 🙂

How can i add a fade effect?
At switching on and off ?
@@hobbyelectroniccircuits7391 yes
You mean a circuit which flashings such a way slow rise and slow fall ?
@@hobbyelectroniccircuits7391 exactly, I've been trying to find a video that explains this
Although I haven't presented a video for it, such a circuit has been made. Opamp IC can be LM358, NE5532, TL072 or 4558. T1 can be BC547, BC548, C828, C945 or C1815 T2 can be BC557, BC558, A564, A733 or A1015 See its website from this link 👉 www.homemade-circuits.com/alternate-onoff-led-fader-circuit/
50PF is not what else can be used
39pF 47pF 56pF 68pF 82pF 100pF
39 ohm is not ..
33 ohms or 47 ohms
Not able to see the readings. The screen is black
Readings should be go until Open Line
So are his fingers, you see them right 🫣

වීඩියෝ එකේ තියෙන Circuit diagram එක බලාගෙන හදාගන්න වෙනවා. ඒකෙ තියෙන්නෙ 12V LED හයක් දාලා හදපු එකක්, ඕනනම් output හයට බල්බ් තුන ගානෙ දාලා ඔක්කොම බල්බ් 18ක් දාගන්න පුළුවන්.
Greetings i got a tda2822 based amp module but its picking up gsm and rf frequencies any advice?
I didn't get you 🤔 TDA2822 is an audio amplifier IC, operated with very low frequencies compared to gsm or radio frequencies.
Will anyone tell me what does the "B" mean in the minute: 1:33 (blue capacitor), mine starts with an "R" and ends with a "UK" or "U<" symbol, Mine doesnt indicate the voltage but it says: "R472K UK" or "R472K U<". It's an A/C indoor PCB)
R = Temperature characteristics Capacitance change within +/-15% at -25 to +85°C temperature range. Capacitance change within +15% and -30% at +85 to +125°C temperature range. 472 = Capacitance value 472 = 4700pF = 4.7nF = 0.0047uF K = Capacitance tolerance +/-10% = +/-470pF = 5170pF or 4230pF I have a doubt about the code UK If it 1K, 2K, 3K or 6K, the maximum DC voltage is 1kV, 2kV, 3.15kV or 6.3kV respectively.
@@hobbyelectroniccircuits7391 Thank you so much, other suggest it's no "UK" they stated that it's more like the brand's name something like "U<"
You are welcome. Good luck with your work 🙏

Sound එකේ Quality එකේ වෙනසක් නම් වෙන්නෙ නෑ, normal bass/treble controls වලට වඩා සියුම්ව bass/mid/treble adjust කරගන්න පුළුවන් මේකෙ තියෙන controls පහෙන්. Stereo amplifier එකකට මේ වගේ දෙකක් හදාගන්න වෙනවා. LA3600 දාල හදපු එකකුත් ඇති ඒකත් බලන්න.

hi sir you hv to go to the pdf of sanyo la 3600 there is a circuit of opamp with the ic pls check thank you
I have checked it, thank you.. I think its a test circuit.
This circuit have to make 5mm led?
Yes, you can. Replace each 12V LED by four 5mm LEDs and 33 ohms resistor which connected in series.
I did the same thing using small 6 electrolitic caps which connected as parallel to base pin of driver transistor and ground path. But non adjustable for tail lighting effect.
Nice. Good work 😊
sir if i use 12v dc adaptor can i use 1 amp or 2 amp how to make balance and volume controller seperate from La 3600 ic from that equalizer
You can use a power supply more than 25mA of current, may be 100mA or 1A or 2A, the IC draws only the current it requires. (maximum allowable power dissipation of the IC is 300mW). You can connect the volume control (stereo potentiometer) and the balance control (mono potentiometer) between graphic equalizer output and power amplifier input.
Hermoso.Trabajo elegante.Muchas gracias.
Thank you for admiring my work 😊
Muy buen video.Te quedo' muy elegante el amplificador.Muchas gracias.
