Winding Machine

This one is for my other hobby - electronics.

Helps with winding coils or whatever you want on the bobbin. The electronic box and the electronics therein are completely optional but help with the counting.

The bobbins and adapters for the bobbins can of course be adjusted to the job on hand.

Additional materials are an M6 stainless steel screw - length depending on what you want to do. Two ballbearings from the same hardware store - they make the running much smoother. The first attempt was without but that is 👎. A few M3 and M4 screws with nuts and washers. The blinding rails help with adjusting for the length. Got them online out of aluminium - but could I have printed them as well?

And of course last but not least, if you want to use the electronics then the spare magnet from the MK3S is needed to drive the hall sensor inside the box. Try before inserting it the hall sensor needs a particular orientation

Assembly instructions

• mount wm handle onto wm wheel R1 using M3x6 screw
• insert ballbearings into wm left bracket R1 and wm right bracket R2.1 and close off with wm lnr bracket R1-counter plate using four M3x6 screws each
• insert M6x"abc"mm bolt with hex head into wm wheel R1
• slide wm thick washer onto bolt
• put through ball bearing of wm left bracket R1
• slide on wm bush
• slide on wm bobbin holder R1
• slide on coil bobbin and connector R2.2 or whatever your bobbin is
• slide on second wm bobbin holder R1
• slide on wm bush
• put bolt through ball bearing of wm right bracket R2.1
• slide wm thick washer onto bolt
• insert M6 nut into wm counterwheel R1
• insert M6 nut into wm counternut R3 with magnet
• tighten assembly with wm counterwheel R1  with nut facing right
• secure with wm counternut R3 with magnet nut facing left 
• before inserting the magnet test which way around it has to be - if using the electronics box - there is only a destructive way to get it out and then you have to print another part.

mount on a plate ore use one with glide rails as you see fit.

As for the electronics the main components are are 

• 3 x 74LS390
• 3 x 74LS47
• 3 x seven segment displays
• 1 lm393 (for a defined reset after switch on)
• a hall sensor from the Arduino
