One of great strength's of this channel is the "Nuts and bolts" approach, always with clear explanations, and such a breath of fresh air from the "Cut and paste THIS code" style channels !
That was very nice. I think this kind of learning hand-on experience is very valuable. As a non-electrical engineer I'd have liked a bit more emphasis on how is the electricity flow as the coils are powered. +1 sub :)
bi-polar, so four blocks of 4 contacts on double circle, a rotating disc with just 1 copper pad on each circle, driven by a dc motor powered thru a sliding resistor, more pads = faster steps. Triple circle for plus/minus/plus config so 2 blocks of 6 contact points and 2x2 copper pads on rotating disc. mechanical PWM where length of pad and spacing between pads determine duty cycle, might need several discs usage: if dc motor also drives some other display and needs stepper, or sliding resistor also powers another device / identical device but in reverse rotation
Similar ones in older CD/DVD drives that I have scrounged from our local disposal/recycling center. Also, you can find stepper and other motors in scrapped printers. In the multi function printers, the scanner drive usually has a motor and gear train that drive to the linear gear rack in the lid...if you take the lid apart, you can cut the linear gear out of it, and get a linear motion device with about 35 cm travel.
hi thanks but then where do I connect the + and - cables inside the protoboard (i.e. where the electronic components are located)? because I don't know from the video, he's left out
Yes you are correct. My high school metal work teacher always pronounced it LED with reference to a lathe leadscrew so it became habit. Realized after video was made ... thanks for the correction.

Appreciate your feedback!
Fantastic video. I love the breadboard demo!
Glad you enjoyed it
Very interesting video and a great explanation to how they work. Thank you.
Very welcome
Thanks for the excellent Tutorial
You are welcome!
Very good explanation, Ken!
Thanks John! Happy New Year to you and your family.
@@0033mer Thanks Ken, and to you.

Nice! Thanks!
Welcome!
Creative,thanks:)
You're welcome!
Merci !!
Welcome!
Muito bom. Mais simples, impossível!

Nowadays old printers use encoders with dc motors. I made a video showing how to use them like steppers...on my 3d printer-in-a-microwave video.
Over a year ago.
hi buddy thanks for the great video.. could you please tell me from where you salvaged that stepper motor with lead screw?
Looks like the ones from an old CD/DVD player or floppy disc.
You can buy it from Amazon. Check the video at 3:11
Your videos are fantastic

The + supply is connected to the center taps of the coils and the - supply to the wire energizing the 4 phase coils as shown at 1:43.

Excellent but it's pronounced "LEEED SCREW" not lead as in solder.
