Excelente video, las puntas de tu osciloscopio estan descalibradas al principio del tutorial, por eso la parte superior de la onda cuadrada aparece curva . El mejor video en el tema, muchas gracias ! 🏆🏆🏆
If the scope readings are correct, the error is more like 0.2% error, much better than 2% error. Amazing accuracy for such an inexpensive device, thank you for the educational videos!
Good idea, different materials require different frequencies, brass doesn't melt properly at the same frequency as steel, if we can change the frequency it would be more efficient and can experiment with many different materials , I like this idea
Ciao. Sto facendo un lavoro dove devo comandare 4 stepper nema 11( premetto sono di base meccanica.) Siccome io ho necessità di comandare tutti e quattro i motori contemporaneamente. Devono girare solo in un senso AVVITATURA. Però devo dare un comando Esterno ( i motori sono chiusi in una scatola di plastica ) che è gestito da un PLC.. Quindi non so come collegare il comando esterno per i motori. Tipo semplice interruttore. Che quando gli mando il 24.volts. Metta in rotazione i quattro motori. Spero di essere stato chiaro nella esposizione del mio problema. Spero che tu mi possa essere di aiuto. P.s. siccome sto facendo un pantografo quattro assi. Sempre con stepper. ( Ma il mio elettricista non ha molta esperienza in queste applicazioni!) In pratica devo trovare sia il CNC ed il programma adatto a SCRIVERE SU DEI PEZZI TONDI. SIA SULLA PARTE PIANA ( FACCIATA ) CHE SULLA PARTE CIRCONFERENZA. SE TU POTRESTI ESSERMI DI AIUTO ( PAGANDO OVVIAMENTE!) TE NE SAREI GRATO. GRAZIE E CONTINUA COSÌ!
Please help with settings. in a variant of this, a 2 channel module... I want to run both the channel on 50% duty cycle @ 1Khz. While I want to run channel 1 instantaneous, I want channel 2 to commence only after Channel 1 reaches zero duty. eg: When Ch.1 = 5v, Ch.2 = 0v and vice versa. Thanks
@@ludicscience Thanks. It will require a bigger secondary module for open any bigger transistor. Or use infra optical gate will better. For flyback sure.
Will the set frequency and duty cycle for both channels individually remain the same even after the power supply is removed? or it gets reset once the power supply is removed.
Do you have a link to this particular module? I have bought identical-looking ones from two sources, and the screens are illegible junk because the digits are not illuminated when looking straight at them (if at all). Yours isn't great (you can tell it's washed out when viewed from exactly straight on), but it's much better than the ones I got.
Would this work with a flyback transformer? Would this produce the required Hz to create arcs? I'm sure you would need to use some extra components to handle the current needed to produce those arcs as well.
Thanks for sharing. It's exciting. I'm learning a lot. The only thing I'm lacking is the imagination of how this could be used to build a multitude of applications
This reminded me of something I worked on back in the 90's where the front control panel multiplexed bulbs where rated at 5 volts but ran off of 28 Volts. All through the magic of PWM.👍
I don’t like buck converter i really like negative buck boost converter mosfets or igbt running cool at load but in positive buck booster converter mosfet get get heat up a bit even with no load on positive voltage so negative buck booster is the most efficient
Hi Ludic. Thanks for another fantastic educational video. Can this be used at 150khz to form the Oscillator component of a longwave Amplitude modulated radio transmitter? If yes, will you build one and show it to us? God bless you and your work.
