    Modular DIY CNC Machine

    Have in mind that the z axis i the most complex and difficult to do.It has to take care of the weight and the forces of the motors. It is a the hardest to do on the CNC in 3D printer there is only weight and forces are not changing the result - the metal or wood does resist the milling device and it is a hard to make i precise.I see that you have engineering background and perhaps you already have the calc.Wish you good and precise CNC.

    Modular DIY CNC Machine

    Definitely expecting the Zaxis redesign. Hope you will post it here :)Excellent job , it is really nice to see such instructable , shame that the site do not have a contest for CNC I will be one of the voters.Keep the good job.Also I agree the overheating and fuses is really a pain.You might check banggood.com for some bits for the CNC or parts - I do not have relation to those site I just use it.Seems here are some people having experience with CNC-ing the aluminum- Do you use cooling agent (oil , water) on the bits ?Fortunately in web now is possible to find CNC parts like stepper motors Nema 17 /23 and all those parts that are hard to obtain, so I hope other people do it.

    I was thinking on this subject and think :If ti is OK maybe a 2 - 4 Gyros used for stabilizing the picture and powered by the Sun with electric motors might just do the trick.In case this is a good idea please let me know (or post instructable) :) .Great project.

    Simple Mini Fire Piston

    Does it works in cold weather like under the freezing point - (I mean leave it for a 1 hour in a freezer and try to make fire)?Also it is possible to have no O-ring - just the piston has to have bigger diameter and use the drill (or CNC) to make the piston the right diameter.Also would be nice to know the diameters of the piston (outer) and cylinder (inner diameter)?Great work, hope it works in cold.

    DIY Self-Locking Nut

    Well here is my solution that is the most cheap and the most hard locking:Get Locktite glue it is cyanoacrylate glue so if you buy other brand (with name cyanoacrylate in the description) it is the same.Do not glue anything, but get the bolt and mark the place where the nut should be and the end of the nut also . In that place on the thread put some drops of the glue and rotate so the drops be in the marks - (use a marker for that).Then leave the bolt in vertical position to dry and try after the glue is really dry - it looks like glass on the thread.If it is not locked repeat the drops of glue procedure.I see you use huge bolts so several drops might work better.The idea is that it is like thread-locker (the one mentioned above) but in reality it is much locking then the thread-locker...

This glue will not help in spark plug just because is is not heat resistant DO NOT DO IT.Do not glue your nuts and bolts - It will come off I tried.Eventually the glue can be stripped off if several times you unscrew it but that is like thread-locker no surprise. About spark plugs - the thread is having special stepping in the end and that seems to block the unscrewing it , so perhaps a quality plug is ALL you need to have - well maybe a new engine as well if all the plugs do not help. But I'm not an expert. Also spark plug that is not screwed to the max is no use for me I have seen to loose pressure on my chainsaws.

    Brick Oven

    About the chiropractor - if you don't already get a weight lifting belt - the bigger the better. Use it tight and do not do unwise weight lifting - use ropes and any mechanical advantage you can think of - levers... (Archimedes).For insulation seems a good idea those rock wool with aluminum foil for ovens like this one.However yours is classic and lovely we all like it for that.I hope you are not running with a hammer after this comment :) to make another one.

  • Cheap Solar Panel for Under $30

    Really great instructable for newbies. Good job.I'm wondering on some ideas to increase the power of a PV by using mirrors, is it worth it and so on?However I haven't got any PV of the mentioned size.Also if you decide to use mirrors you might need to coo the PV using something like aluminum heat sink and even cooler/fan, so this PV remain intact.I might be possible to gain more then 10x more power from the PV using mirrors with a area of 15x the area of PV or some.If you don't mind to try I will be appreciated.

  • Super Easy No-knead Sourdough Bread

    Forgot to mention do not waste the water with chickpeas it has yeast that you need , so make a dough with that water.

    I use chickpeas (10 or so) soaked in water that just covers them - soaking is for a night to 24 hours (leave it at 20-35 Celsius not in fridge or cold place). Then smash and use as yeast.After having a dough save a peace for using it as a yeast for next time - it is p to 3 days in fridge.In my country is not possible to buy such yeast (actually this name is wrong) .This bread of mine is having a thick crust and I cannot resist eating it when hot :) - yours looks so good man I like it. I hope you eat it at once :) .Enjoy.

  • Arduino Controlled Versatile Timer/controller

    So you are using rotary encoder that has an integrated switch - I have none of those and I expected that there is no such encoders.Sorry about that.The power formula is Voltage of the grid (i.e. 220V or 110V) * (The current SSR switches) 20A = Wattage of the consumer that can be safely switched on and off.That is why I pointed it is a overkill for some applications - like switching a LED lamps or activating motors or so...Thanks for the instructable.

  • Arduino Controlled Versatile Timer/controller

    You did not mention but perhaps the 3 legged chip (that looks like transistor) is a voltage regulator of kind.You got misspelled "Rotory Encoder" perhaps RotAry Encoder.However perhaps using potentiometer could be much simpler - because Arduino has analog inputs.Also for having exact time intervals you could use RTC clock module - also that module ca give the timer exact time in the date to tun on - like 17:50 (5:50 PM) .You could mention that the SSR might be overkill for some projects - if the grid is 220Volts then it is 220*20=4400Wats that is more then a oven in full power - all hotplates and all the heaters in the oven - if 110V then 2200Wats like some powerful hotplates - I would probably use it to switch a blue/red lamp for plant grow which is most of 10-100Wats. Howeve...

However the price of SSRs are drastically low for 1-5Ampers - like 2 dollars or so. Good job thou. It is not for baginner in Arduino.

    I think I will put a dummy like those in clothing shops - similar.Also it might have my face printed :) or 3d printer if a run my 3d printer (a stall project at the moment).Also a something that shakes the curtain of a window for a while like a homekeeper does to look better curtain.

    Great instructable.I made something more complex - using arduino to test and calc and show the real capacity on a screen.Probably I have to make an instructable for that.Basically I used 1 ohm and heated it but I used MOSFET that has neglegent resistance of 0.01 (those high current IRF44) so when the 3V are reached I stopped discharging.The Arduino calcs all the resistance and voltage and - only NCRs purchased from banggood was good at 3.1Ah also I tested the pink ones from the same site (should be Samsung unbranded) and Sanyo unbranded all was as advertised - but others noname (no brands not unbranded) those are useless non of them have even 2000mAh or 2Ah so by those I tested and won't sorry - NCR that I tested was dark blue/cyan colored - there are new that claim 3.4Ah but not purcha...

    Bike wheel induction safety light

    I would do it in reverse - not the spokes to light but the rear light to be a red LED powered by dynamo/magnet on the spoke(s) .Also replacing the rectifier is a great idea and the resistor is not needed you might not make too much current to burn the LED - if you do - then put more LEDs in parallel.Also Joule Thief circuit might be e good idea and super-capacitor / ultra-capacitor.Great - good work.
