this is the project: i want to use a remote to activate a fan. if i use the 555 in a monostable way, it will activate the relay and remain stable untill the 555 times out as a result of the delay. now i want something that will be stable...
i'm designing a project. i want to use a 555 timer ic to activate a relay and the relay remains stable. i know some other circuits will be involved apart from the 555 timer. please how do i make the relay stable after activating it with the...
hi guys...got a little tired of soldering and i decided to take some experiment out.
now this one, i took-out the lence of a dead CD rom and i actually got deep down into the coil. i really could not figure-out what i saw, it looked like a...
Hi guys,
I tried this little project out. i built an infrared transmiter with the CD4069 hex inverter and the output frequency was at 10KHZ. now i still would want to use thesame IC to build the receiver but how to configure the pins are my...
Hi chaps,
i'm a physics electronics student. i'm building a project which is an RC (radio controlled) car. i'm not good in PIC programming, hence i want to use RF technology. i can build the transmitter and receiver circuits very well. but...
thanks. actually i did not use an IC for the audio/video transmitter. I used 4 transistors which are: C1852 for the audio, C945 for the mixer stage, C1105 for the Video stage and C2254 for the oscillator stage. I did not use any IC at all for it...
Hello... all i'm really sorry for the first post I made. i'll be more ellaborate now. My name is Timothy Ojeaga. from Nigeria. And i'm 23 years of age. I love electronics. on this day, I decided to build an audio video transmitter or sender. now, the...
I BUILT AN AUDIO/VIDEO TRANSMITTER. THE VIDEO SIDE WORKED PERFECTLY WELL, BUT THE AUDIO DID NOT. I USED A MIXER WITH THE YELLOW SLUG CAP. BUT WHEN I REGULATE THE MIXER WITH A PRICISSION SCREW DRIVER, IT DOES NOT REGULATE THE FREQENCY. BUT THE PICTURES...
I HAVE BEEN WORKING ON A PROJECT FOR THE PAST THREE MONTHS WHICH IS "ECHO CIRCUIT". I HAVE AN IDEA AND I TRIED TO SEE IF I COULD USE FIVE JRC4558 IC, IN SERIES. BUT AT INTERVAL BETWEEN EACH OF THE ICS, THERE HAS TO BE A KIND OF DELAY. AT LEAST...
please if TDA is the best kindly give me the link.
Please if TDA is the best kindly give me the link regardless the output power. I'll fix the final output power my self. please kindly include the tone controls. if it has any. thanks.
