hello! i know this is an old video but i am doing a proyect and my queston is: how does the value of the inductor affects on the voltage conversion value? or its depends of the switch frequency only? i will be very greatful if you could help me, cheers!!
Hey Julian, Iam a long term fan and just comming month iam going to finish my electronics engineering school stuff. You are one of the reasons why i got into electronics and went to University for it.
But after seeing your video's again after long while. I still wonder why you don't just buy a Labbench PSU? They are dirt cheap nowadays and not that bad either.
Never thought I'm going to hear 15KHz sounds considering I never seen a CRT tube in 10 years. Good to know my headphones could pump out 15KHz. lol
thanks for this issue. i used a lamp as well as payload, on my b00st circuits. sometimes, it would help a little, while seeking on the web, if you could shortly put the target goal of a single project, in the description box.
here, u may create 5-30 v out of 12v, regarding the consumption power over all. the clock of ur script on arduino would also help to enlight, as it is a little tricky, to raise the frequency above some khz, to hundrets of khz or mhz maybe.
finding the proper coil and capacitor is another story, so probing and measurement over the different steps could guide one to the end of such thing.
cheers
There is a beeping noise when you turn there poti. where does that come from?
I'd imagine that with the harmonics you generate a lot of EM hash up the spectrum into at least the AM Broadcast range.
WHAT WIKIPEDIA DO YOU USE? IS IT POSSIBLE YOU COULD SHARE THE LINK. THANKS
There is NOT 15 watts going through your bulb. At least half of that is passing straight through your fet to ground lol.
How we can give feedback to arduino for village up and down…??
Very nice job
theres not really 12w on that bulb, your switching frequency is too low, the core gets saturated after lets say 10µs and the other 90µs of your 100µs pulse duration is just a dead short until the fet opens.
Just to be silly: Closerliestestest? 🙂
Where's the resistor?
Surely this demo would be more impressive if you boosted from a lower voltage (say 6v) when powering a 12v bulb rather than using an input of 12v for a 12v bulb!
