[@siriponga7911]

Thank you for this tutorial, I have implemented this on an ikea rail curtain with a worm-gear motor instead of a stepper motor with reed switches as end stops. The only unfortunate thing is I used mono fishing line instead of the braided line as recommended in this video description. This caused stretching of one line as the motor is pulling the curtain, resulting in one taut, and one slack line. Due to this, the slack line gets reeled into the wrong slot by chance, causing the whole thing to fail. In conclusion, use a zero stretch braided line as mentioned in the video description. Don't go the cheap route and get the mono fishing line as it stretches a lot.

[@Zhak7]

As for the wifi issue you don't need to keep connection alive the whole time the motor spins, you can do it in between. Once the command has been received, let the motor open/close the curtain fully, then re-check wifi connectivity. Very nice project well done !

[@sayvibes3393]

Hey did you make it ? Can I use a generic esp8266 ?

[@curiosityandchaos7171]

I noticed a couple people saying that their capacitors exploded when they were trying this out. If your capacitor explodes, here's the three most likely reasons and how to fix them: 1. Your capacitor is plugged in the wrong way. Make sure that the negative terminal (the shorter leg) is in the same row as ground. 2. There is too much voltage running through the capacitor. I'm not an electrical engineer, but I used a 50v capacitor and it worked fine. Since it's running off a 12v battery pack, I suspect you could also use a 25v or 35v capacitor without any issues. 3. Your motor driver is overheating and heating up the capacitor. If your motor driver came with a heat sink, you can stick it straight to the top of the board, and it should help cool it down.

[@donnyf12]

Just a suggestion, define a variable near the top of your code for the travel time setting from line 91 and use the variable on line 91. Also do the same for the switch name (line 60), the SSID and Password. In essence, you will be defining a config block that will allow the user to be able to make all the definitions necessary and have it at the top of the code so they don't have to go digging around trying to find things.

[@DIYMachines]

Very good suggestion Donny. I will do that on my next project. It would make it much easy for the user and for me to explain in the video. I won't amend this one as people will still try to follow the instructions in the video. Thanks.

I am too lazy 😔😔 so I thought I will make my room automated 🤭. But after watching this video 😂 gezzz I don't want to do it anymore.

[@fastbike9845]

Very inspirational. I'd be wary of automating it for when the house is not occupied as there is no fail safe mode (limit switches, over current detection, motor temp cutout etc) And very nice use of a custom printed enclosure to protect and hide the gubbins behind the fabric. However it fails on the WAF, there is no way I could use such noisy motors in my house. I think it may be caused by the cheap and cheerful motor drives, maybe a Trinamic based drive would quieten things down.

I just ended Mine yesterday, My curtains and Alexa were opening and closing while watching the video over and over again to spot details that I missed since at that point it had the original voice command, the length and running time fits Ok with my window size, need to replace the phone charger I used to power it has too low voltage and mha so the nema has more torque, while that, used oil to smooth where the curtains got stuck because of friction, I have wood rings so I passed the stings along the center of the whole setup and made the strings go in a straight line, at the ends I used a piece of curved straw to ease friction and maintain in place the string ,My setup was about 26-28 Us

[@DIYMachines]

Yes, maybe next time I make a video which includes Alexa commands I'll beep out the word Alexa in the video so as not to create havoc with peoples devices. :)

Nice lil' video :) - I was curious on the ammount of brainpower required to emulate a smart device

[@colincassidy9128]

Hi, great video! Anyway to have this put the curtain in 3 positions? Open, Closed and Cleaning for instance? Is it due to the the restrictions of it emulating the Wemo plug?

[@IGIVEINPS3]

Nicly done cheers. I'd set up a routine so u could say alexa close the curtains. instead of turn curtains off.

[@cytokynesys]

Hello, did you ever determine a way to eliminate the 'pause' from the spinning of the motor? I've modified your design slightly, but the pause could cause damage, as it is not predictable! Thanks.

[@markvk42]

I wish id found this before i started to automate my curtains! im almost finished the project but might mod it to include some of your ideas, im curious to know how long your batteries lasted.

[@DIYMachines]

Thanks Mark, the batteries lasted at least three weeks (I had to scavenge its parts for another project). Some other have modified the project to run entirely without batteries which could be an option.

[@bonelifer]

Only thing I'd like to see different is using MQTT to control it via Home Assistant. Not quiet something I can bring about myself. That said, the hardware implementation is great and an easy to understand tutorial.

[@DIYMachines]

That would be cool, likewise that's not something I have the knowledge to do - though I think other have added it themselves. Glad you like the hardware.

[@xainisheikh]

14:20, you mislead because if you bring the string from over the center hanger and then tie the left curtain it will obviously pull the curtain towards the right side.

[@Kuno_23]

Would this work with the hue smart plug principle on zigbee network or does zigbee make a component of sorts ? Great videos, keep it up 👍🏻👍🏻👍🏻

[@kendesign3622]

23:33 I'm no expert on Arduino but.. it sounds like the stepper motor is stalling out. That tiny driver is very current limited. As far as blaming it on your band width I can't see that to be the case. The wifi is sending a simple on or off command, once the microcontroller receives that it executes the code that's stored on the microcontroller. Put in a stepper driver that can handle more current and I bet you your "bandwidth" problem goes away.

[@wilmercb]

Thanks for your tutorials! ...wondering would you do one using iOS Siri? It would be same? Thanks

[@TheFlyingKiwiNZ]

Would an esp32 work better than esp8266 for retaining wifi connection while driving the curtain? It has more processing power

[@bulk6622]

Hi DIY Machine, great video and all you downloads and stl files work great every time. Can this be done on a 28byj-48 and driver. This would also would be good to with a lcd shield with clock for 2 pin motor to work off line if there is any call for that as not every one is smart phone friendly includes me. Many thanks Kevin

[@jofie2302]

How do you cater for when something goes wrong, e.g. the curtain gets stuck before it reaches the open/closed position? Especially when adding limit switches, you don't want that motor running all the time when you're away on holiday. Thinking in terms of adding overcurrent detection, but is that not a build-in feature somewhere already?

[@savioluis7431]

I loved this project. Well explained. Thanks a lot. I have a couple of questions/suggestions: I see you used a 100 microfarad 50v capacitor. Can I use a 100 microfarad 35v capacitor instead? Will the voltage matter in this project? Also in some other videos if you can explain how the voltage on a capacitor matters.

[@graychenault1435]

Yes, 35V is plenty good. As long as the cap rating exceeds the voltage it's seeing (12v in this case) , you are GTG.

[@danwilson9684]

I'm looking to create my own system like yours, I have bay windows which use a curtain track rather than a pole. I'm going to see if this is suitable (need to figure out how much it weighs in total), or if not, something like a wall mounted box that will simply pull the blinds open with a time based condition.

[@arabianmenace527]

I guess you can add limit switches and command it to turn till it reaches the switch... that will fix the issue of steps to close the curtain.. not sure if that cud fix the wifi connection issue because via the code you may not need the the constant communication whilst stepping

[@TheMilkMannnn]

Hey man! I can’t wait to give this a go. I’m just thinking, is there any way to connect it to a 12 V power supply/outlet? That way there’d be no need to go through batteries.

[@Jespertheend2]

Would it be possible to power the stepper motor with a 12v power adapter? You'll have to have a cable running to the outlets for the chips anyway, and then you won't have to change the batteries every once in a while.

I'm going to try this when the parts I ordered get in from AliExpress. I'm going to try with a 5V 2A USB brick first because from what I'm reading input voltage isn't as important for stepper motors as current, and the rated current for the one he lists is 2A

Do you need to keep the PC hooked up to the Feather Huzzah? I would like to say I have this running on my bench. I have not hooked it up to any curtains yet. I have to say this is awesome! My only problem is that you could say "turn off" or "turn on" multiple times in a row and cause all kinds of havoc with the curtains and pulling mechanics. I am thinking of adding some kind of limit switches but I am no coder.

[@DIYMachines]

Hi S Griffith. You don’t need to keep it hooked up to your PC after you have uploaded the program. Limit switches would be a good idea. You would just need to change the section of the code that controls how many times the motor turns forwards or backwards to go until it detected a contact at one of the limit switches. I don’t have the time at the moment but plenty of people have made some excellent suggestions for improvements so I hope to do a V2 next year.
