Så enkelt att jag tror att till och med solhaga skulle kunna bygga en sådan maskin  . |

Nä, jag brukar hålla efter undervegetationen med en hårtrimmer... |

Fuling, du vet väl att lindare är ett annat namn på sutare?
De är väldigt duktiga på att trassla in linan i undervegetationen. Har du haft sådana problem med din lindare? |

Ah, den där videon tittade jag på ett antal gånger när jag byggde min egen Arduinobaserade lindare. |

Jag håller med att för många delar har använts.
Bra inspiration annars, även Wintergatan är en sådan.
Jag har tio SLAPS-spolar att linda.
Men det tar nog längre än 10x45 minuter att göra en maskin för ändamålet.
Så pix hinner nog före! |

Han lade till detta:
"It's completely computer controlled, so rather than a counter, the transformer bobbin is attached to a stepper motor and a computer tells the motor to step X number of times.
Theoretically with a bit more careful thought and engineering, you can set this up to be completely automated. If you really wanted to go crazy, you could have a multiple spindle setup and have some type of CNC taping machine in the mix so that you can slap on some bobbins and a butt load of wire at night and in the morning you would have your PSU, choke, input, output, and interstage transformers all waiting for you".
Jag tror att om solhaga får fundera ett par dagar och bli klar med ett par projekt så bygger han en sån här även om han inte behöver någon transformator. Eller så gör pix det. Vem blir först? |

Han som postade länken kommenterade så här:
"It is definitely a sight to behold. He has a couple videos on his channel where he shows more angles and features. The real takeaway is the wire tensioner. Everything else is fairly straightforward. To give some perspective, some wire tensioners being sold for transformer winders are friction based devices. They actually have a drag wheel that pinches your wire. This can work, but you risk damaging the insulation layer of the magnet wire.
The better wire tensioners will work by providing feedback to a motor that will let wire go from the spool at a very particular rate, however, they cost several hundred if not thousands. This guy's feedback mechanism is that little cart connected to the spring with a piece of linear tape to the side to monitor the position of the cart. This is actually how a printer works and most of these parts can be sourced from a scrap printer to make the cost of the project a lot cheaper while still maintaining a very high degree of accuracy.
It's pretty freaking ingenious. His design can also be made for a lot cheaper too. I get the feeling that his machine is built the way it is because he had a lot of those parts on hand. If you ditch a lot of the gears and belts by making all your motors direct drive, it should reduce the cost by quite a bit.
The ONLY modification I would love to make is replacing that spring on the cart with a load cell or a load cell and a spring. That way I can know the amount of tension I put on the wire and dial it in for best performance. Other than that, this machine is probably about as good as it gets.
I might end up sending you a few practice transformers for you to test considering you have more test equipment than I do : P".
Det var inte riktat till mig utan på ett forum jag besöker. |

Nej, jag behöver ingen utgångstransformator
Nej, jag skulle inte klara av att bygga en slik maskin  .
Imponerande bygge dock. |

Behöver du en transformator?
