Sir can you make these kinds of project th-cam.com/video/netHzDIee1g/w-d-xo.htmlsi=xR9zjVMm2zQwdckq

Algo (bastante) chapucero.

Guantes con ratos, no cazan gatos 😆 😂 🤣 🤭 👀

Nice design, not that it can't be done without a 3d printer. Foil might be ok for signal level circuits, but not for power handling. 7 mhz for example needs 1 mm/.040" thickness plates using the 5 skin depth rule of thumb. Forget about using it for a magnetic loop antenna.

Yep. I'll just run right down to the store and buy me a 3-d printer and learn how to right g-code. Oh wait. I'll just buy a over priced tuning cap. Great job by the way. I just don't have that luxury.

nessuno si e accorto che il condensatore e' in corto circuito . con lo strummnto misurava gli ohm non la capacita .....svegliaaaa

Where is the PCB design for etching it?

Howdy. Nice idea. Very suitable for further development like scaling up and using several pipes. Regards.

Did you find it smooth to turn? How about the back-lash, noticeable? Thanks for this!

Do market survey. Produce more and put them for sale

I feel the title is a bit too simple as it makes it seem like it will just display one QR code which anyone can print and it will do the purpose. The title should be more like "Dynamic QR Display Badge" or "Configurable QR Display Badge using ESP8266". Mentioning ESP8266 will help ppl like me find it more easily. Plus you haven't added any tags in your video. Maybe consider learning a bit about youtube marketing/video promotion. That's for reaching out to more audiences. Great educational video overall, just need to work more on marketing so you can reach out to more ppl and others can benefit from it as well :)

Good job bro i need more of these

If you want to make this look a little more professional then rebate the numbers into the 3D print (ideally as a part of the design but you could use a cutter) then fill with either paint or wax crayon.

Thank you for this tutorial.

The meter is marked on the screen as nano. This type of capacitor would be adequate for receiving purposes only, transmit power of any appreciable amount would require something other than aluminum foil and a better dielectric. I would recommend instead of using paper and aluminum foil simply replace the two plates with pieces of copper or aluminum pipe. Instead of using a manually turning knob which looks to be very inconvenient, a stepper motor could be used.

nice

Great creation bro.

Great one!

reading the digits is not that easy but the concept to use rotary encoder for measuring the steps is good
