This channel shows about electronics and random technical stuffs that can make your life easier. Most of the videos are very basic innovations that can be done by anyone like me a 18 year old Filipino engineering student . I just come here to share my cool and little ideas about electronics, specially in innovating things.
Update Im now an electronics engineer/technician in ph.
I am trying to do something similar - except, I am trying to bypass the bluetooth receiver - I just want to add an INPUT to my bluetooth speaker, (guitar project). How hard would it be to bypass a pockettunes PT200? I've popped it open, and oh MAN I have no idea where to start.
But there was a problem in xl6009 or other type of boost converter i personally use xl6009 when we convert 3.7v to 9V or 12v it works good But when the battary voltage drops its immediately power around 40v maximum volt my many led stripes are damaged by using this boost converters the best way to mitigate this issue is my providing constant volt to the module ex: you use SMPS circuit or voltage regulator ex: 12V battary using 7805 Ic it power const 5V use it with module works good!
Which type of hack is this bro ..... any one can do this simple change . i thought you goanna powering 9v Multimeter with as low volt as 3 or 4 volt so we can replace 9v with rechargeable li-ion battery using just one cell !! i think it's possible because there are some brand that uses only 2 AA cell in it's Multi meter
Will this circuit automatically switch back off if the button is not pressed a second time? I'm trying to find a 555 circuit with single button push-on/push-off function which also will time out and switch off on its own.
Nice video.Thank you. Is there any chance you could show us how to make an audio jack INPUT on a bluetooth headphones?My bluetooth headphones do not have a 3,5mm output jack.Thanks
Thanks for this video. This is exactly the information I was looking for, that too in a good format. Best thing about the video is that he explained all the important points in very easy and simple way. Good job👍🏻
Hey, How much current can you get from this power supply? I have an epson power supply which can provide half amp. I got another question as well, my epson power supply uses feedback voltage to turn on the primary part of circuit, how did you get the output voltage? Mine turns on and then it turns off. Do you have schematics of this power supply? By the way, how to provide feedback voltage to turn printer's power supply on? Thank you.
@@JohnSmith-mf6pe 600milliAmps, i showed a schematic on the video but not on the secondary side only, if your power supply has a three pin -output,one of it is the enable/disable pin, you need to pull up or pull down . But i dont know exactly if its like yours. But this printer has 3 pin but i just leave the enable/disable pin .but it readily works
pull up means connect it to high voltage or the + 5 volts or pulldown connect it to the negative /GND . But in my case,pulling it down will disables it.
Note : this only works on simple power supplies that dont have a undervoltage protection and also lowering the voltage too much will a also cause it to shutdown
Thanks a lot. The power supply I'm talking about us used in epson Cx3200. As I checked in service manual, it has over voltage protection (ovp) and power supply controler (psc). Could you tell me how to turn it on? Do you have access to similar power supply? Thanks.
you need know the pin-out of your 3.5mm female connector. normally it has 4 or 3 pins . just 2 of the pins will be used because a speaker has 2 wires .
do yo mean to have a higher capacity? if you parallel 3 of the li-ion battery their voltage will be equal. 4.2 volts when fully charged 3 volts when discharged.
Is there a way to get to the line level signal before it is amplified? I took the audio out on a motorola "Deck" bluetooth speaker that happens to have an audio output jack (the only one I know of that has this) ; oddly eough, it does NOT mute the built in speaker, so I just connected it to an amplified subwoofer because the Deck has quite satisfactory midrange and treble, but limited bass response. The subwoofer has a variable internal crossover so you can set it to filter out what is being handled by the Deck, leaving it to kick in right where the Deck drops off - starting about 250 Hz but non-existant below 100 Hz. The subwoofer has a 12 inch speaker, so it can cover all the way down to 30-50 Hz quite easily. It sounds great, but if was fed a balanced low-impedance line level input instead of a headphone signal, it would be cleaner. Thanks for the video!
Sir gawa ka ng video, lagyan mo yang bluetooth speaker ng audio jack cable para pwede isaksak sa component o may aux input na may dalawang speakers. Thanks
