Arduino or Teensy coil winder - any code already out there?

I am in the process of deciding on a normal 8bit Arduino platform or a Teensy for my coil winder project.A found some interesting projects online, some with the code available too.But I was wondering if someone already implemented more than just winding a coil in such a project?At is a nice winder based on a normal Arduino while the Alba winder uses a Teensy already to gain more precision and speed I guess.Misusing some printer or CNC code to be able to generate coils by G-code sounded nice at first but turned out to be more complex than actually required.My goal is actually rather simple despite the size and all, so let me try to explain what I want to be able to do:Have a modular winder setup so basically any winding task can be done with just two stepper motors.One for the spin, one to position the wire.Additions like limit switches and external counters are nice but usually not required for such a task if the the code is properly done.As a basic winder like all the examples out there it should be possible to just enter the wire diamter and number of turns and then push a button to wait for the finnished coil.In theory things like pitch or spacing can be calculated externally and then entered as a fictive wire diameter but of course this would be not user friendly enough ;)For special RF coils it is often required to keep an even turn spacing as well as creating a coil with many layers.So far I have been unable to find any usable code for this purpose that does not require glue, guides or at least waxing the wire.Although this seems to be simple enough, when adding things like a display and counters it soon starts to get messy with timings and steps.Is there anything out there that works properly on a 8bit processor with reasonable speed?Originally I wanted to use an OLED with touchscreen.This turned out to be too much for the timing on a Mega.Without messing around with timers and interrupts it seem a 20x4 LCD is the only option.Even then the refresh must be in sync with the tart of a new turn as otherwise the motors miss some steps here and there.These things run a 3D printer or little laser cutter with ease, so I am definately doing something wong with my approach here LOL

Is it possible to take a low heat spread over a large area and convert it into a high heat in a small area? For example a normal fireplace can't melt cast iron, but 2 or three create enough energy. Could you concentrate that? (thats just an example, I have a much more brilliant plan) Thanks

Add permalinks: Link to individual posts

It is quite often we need to link to specific responses to a forum thread. These should be permalinks. See for an example of a site that has permalinks:  is another example where one can link to individual answers, not just to the entire thread. This is missing from the Instructables site. Please consider adding that capability.

Rip-offs from designers

We've all seen it, and for a lot of people, it's why we're here: simple, neat, easily-executed ideas presented as high art or grand design, and sold at jaw-dropping prices. The latest example I've come across is these coat-hooks.  Cut from brass and stainless steel, they are going to be "launched" at the London Design Festival but Visuallyod. A launch event.  For coat hooks? Cut and bent from a bit of brass sheet? I shudder to think of the price as well - there's no price on their own website, but they charge £490 ($750) for some sticks cast in pottery and tied together with old string. Anyway, rant over (for now).  What examples of rip-off design have you seen?  What examples have you copied? EDIT: Sudden thought - even if you haven't made them yourselves, what are your favourite examples of Instructables recreating designer rip-offs at budget prices?

2 small more microcontroller questions...

Getting it in the mail soon, so I might as well ask while i wait. 1: Can you put 9V into a input, and out a output.. or is that way too much for the poor guy? 2: Do micro controllers have ability's to read voltage on the input? Like if I want to say when its lower than 1V on input0 it will open output 0 (which sounds a buzzer) for beginner projects. I don't expect examples. I example a yes/no answer. If you feel you need to give an example, feel free. Just don't want you guys to think im requesting codes!

Wooden blender base // power drill to food blender converter

I love projects which use power drills to power kitchen appliances: example 1 example 2 example 3 example 4 I live in a tiny home and the idea of having just one DC motor acting as a multi-functional appliances makes sense to me. Now, what I would love is to use my power drill as a food processor/blender. Actually, people have already made an immersion blender with a paint mixer and a normal blender by sticking the drill bit directly into an old blender blade. This is a great start, but it's not the best for when I need to blend something at high speeds for a long time. What would be great is to expand that last instructable with a base such that A) the vessel is upright and B) secure, and that C) I can safely push my drill against without worrying about twisting or anything. I've attached a potential schematic. Where I get lost is how to keep the rods/gears securely in place in a wooden/acrylic base without causing lots of friction against wood. I have close to zero handyman experience so if someone took this up I'd be eternally grateful! Alternatively, a belt could be used as done in food processors (example). It seems like it would be harder to drill downwards onto a kitchen counter, though.

Hi, Do you have any idea how to upgrade from the things that we already owned. It is not from waste product. I would like to try to upgrade the things. For example, I have an umbrella, then I want to add a small fan into that umbrella, so whenever the user use that umbrella at blazing-outdoor, he/she can fell the cold.  But, I do not  want to take part in programming and complex mechanical part. I really want to try something simple more example and it is better if can help other's. Thanks !

Not Anagrams

We're all familiar with anagrams?Rearranging the letters of a word phrase, or name to produce a new phrase, using all the original letters and only once each.For example* "Ripley's Believe it or Not" - "Lively enterprise. Boo it"Or anagrams of a former US PresidentHowever, more fun are not-anagramsFor example*Tony Blair - Lying hairdresser.Richard Branson - Lucifer chinned racketeer.Peter Stringfellow - Tangerine child catcher.Do you know of any amusing "not-anagrams"?Not-anagrams should sound like anagrams, they're not clever or amusing if they don't(Original idea from Viz comic / magazine, years ago)
