  • 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.

    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...see more »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. 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.

  • 'Home Alone' burglar deterrent/ Use Attiny13 to drive a Steppermotor and a Servo

    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.

    Thanks for the instructable.Great job I will try it - or perhaps I will make something similar.

    Those video mp4 are not downloadable if exists anymore - perhaps it is a some politics of the instructables site ?However it is better to be some little text instead video.

    Capacity Test Of Fake 18650

    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...see more »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 purchased or tested.If interested I will publish my battery capacity tester :)Enjoy

    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.
