Bro u r videos and works are like heaven to me as an electrical engineer

This video definitely has more info and more details! Definitely taught me a lot about VFD's.

Much more functional than my current method of lighting the VFD displays in my upcycling e-waste art pieces - i.e. UV leds reflected at it 🤣🤷‍♂ I feel confident in giving it a go now - even handier that Arduinos can be used to drive chip function as I'm already implementing them for kinematics. Good work lad, 10/5 stars. Or 20/15 grid segments ;)

I just find your channel and I already love it, you have really great videos and info!

Amazing video! Thanks a lot for sharing your knowledge

Thx for this vid it helps alot. There isn't alot of videos about reusing displays from old equipment

The Mega328B has a built-in hardware SPI. So hardware shift register and things to read/write them out/in to parallel. So the clock rate shouldn't matter if you read the data quickly enough in the software and push it to serial. The hardware pins are 11, 12, 13. You have free choice for the chip select and reset. Then the IC is even faster than in software SPI. There are now VFDs that have the multiplexing driver IC directly in the glass housing. These require SIP, 5V, 2V, 15V and an R-C for the internal clock. These are also available with a circuit board where the required voltages are provided.

I've got a load of these sitting around waiting to be reused.... and a bunch of driver chips.... so thanks for a bit of extra info.

great ideas thanks for fresh unique content, hope you post more.

Nicely done and greatly appreciate your work. fun reusing all this free electronics like the VFDs. Best Wishes

Than you very much, I managed to modify your code to use with MSM9201 driver, which uses slightly different command table.

11:00 If it's a multiplexed display then grid control is essential.

Nice job and explanation.

For the section beginning at 5:29 discussing how to power a VFD: What is kind of a mind bender for me is that the negative return path for the independent DC supply that powers the grid and segments is solely through the independent AC supply that powers the filament. It would have been nice if the connector between the AC power supply and the DC negative was made by a black wire to indicate that this is a negative return path, and not another positive DC power source (green wires). Anyway, the result is a diode / triode structure, where positive voltage starts at the anode / segments, and works its way to the cathode / filament. Since VFDs are high impedance, there shouldn't be much current (DC conventional flow current) from anode to cathode.

Okei informeishon ,favorit ,!!!!

Good luck sir....

These were in everything from car stereos to video recorders and hand held game consoles..

Which VFD driver are you using? Or can another one be used, like PT6312 or PT6315? Thanks

25:54 why not use shiftOut(datapin, clockpin, LSBFIRST, 'W'); instead?

Where did you get this nice VFD?

That was fun

VFD Pros. : Bright, cool, not affected by temperature. VFD Cons. : Large power consumption, burn-in occurs.

is there a simple circuit thats DC to AC to make portable electronics with VFD's

How about driving segments with PWM for dimming/glowing effects?

Why do you need the mesh?

can you use a DC voltage to power those filaments?

damn i have a lot of them but now without the chip xD (didnt know its important)

Wish we could make VFD's at home.

How can converte a dc to ac to make powring the vfd more easy

RIP. ➕

Hi How can increase brightness?

Hi, Is it possible to use a DC voltage for the cathode?

Thanks for this great video, very informative! Regarding your PrintString() function, I would suggest making a class that derives from the standard Arduino Print abstract class. This way you could vfd.print() just like you would Serial.print(). Here is my proposed implementation: class : public Print // anonymous class { const uint8_t CMD_DCRAM = 0x10; // starting at COM1 public: // Write a string of characters. size_t write(const uint8_t *buffer, size_t size) { digitalWrite(sspin, LOW); shiftOut(datapin, clockpin, LSBFIRST, CMD_DCRAM); for (size_t i = 0; i < size; i++) shiftOut(datapin, clockpin, LSBFIRST, buffer[i]); digitalWrite(sspin, HIGH); return size; } // Write a character as a 1-char string. size_t write(uint8_t c) { return write(&c, 1); } } vfd; // pre-instantiate This way you inherit all the functionality of Serial.print(): vfd.print("Hello, World!"); vfd.print(some_variable); // automatically converted to ASCII
