I'm Stefano also known as “Electronic Projects Stefano91ste” - Here my mission is to show simple Electronic Projects and teach how to do them, I also love creating some new ideas about the world of Electronics. In any video you will find circuit diagram, PCB files and explanations, so you can easily make it!
General Info: [Update 28/6/2024] ⚠️ • All the projects I posted are 100% working and rigorously tested on breadboard or PCB. • I share for free all circuit diagram, PCB, etc, you can use them for personal or educational purposes. • I do not allow my projects and PCBs to be used for profit or sponsored videos. • I do not allow my videos to be re-uploaded on any platform.
great job sir. Its working perfectly, i added a transistor to switch an LED with higher voltage rating and also to slow down the flashing speed i connected two 1uf in parallel .
My laser light is also 303 i try all method even the focal lentgh etc but i cant burn a matchstick did i have to change my battery i have the battery which come with the laser can i change it with lithium battery does it have changes on my laser power please reply ❤
Hi, unfortunately after 2016 the lasers were weakened for safety reasons. With those that can be purchased nowadays it is impossible to carry out these experiments that could have been carried out years ago

Ciao Andrea ho una Ford fiesta titanium del 2010 ,ho scoperto di non avere acqua ,quando sono andato a metterla bolliva è usciva di fuori insieme al fumo ,la ventola non attaccava ,secondo te ho rotto la testata?
Ciao, se dovessi rompere la guarnizione della testata vedresti del fumo chiaro/ bianco uscire dallo scarico. Ad ogni modo vai immediatamente da un meccanico. Ps: non so chi sia Andrea
most of the board looks fine... is the HV components of the board damaged? also still kind of surprised the breaker took that long to trip due to a short.
Yes, the low voltage part was deactivated immediately, while the high voltage remained active. I have two emergency switches, the first is dedicated to the laboratory, the second covers the whole house (including the laboratory) I assume they didn't stop immediately since dispersion was minimal and confined to the plastic container
Hola muchas gracias por el aporte, una consulta porque pones en la lista "1x 3 MΩ Resistor 1/4 Watt" pero finalmente veo en el circuito que usas de 4.7 MΩ ??? o es mejor la de 4.7M ??
I got a a few batteries from Jcar and took my vape on with me to make sure I got the right ones and they say FIRE HAZARD NOT FOR VAPE. So,does that mean I can't use them or what they sold it to me and said I could use them
Very useful to me -- i received my package from Ebay with NO DESCRIPTIONs at all: no info on the modules, no paper, not even an internet link. Thank you!
Normal operation. Mine does it too. The circuit that drives the display has radio interference. It goes dark so you can hear the fm signal. Has static when it's on.
@@Stefano91ste ah io stavo pensando a provare a crearne uno sostituendo il chip da 4 megabyte su esp32 a 16 megabyte però non sapevo cosa aspettarmi da un microcontrollore...
