Honestly, thanks for doing this. I was looking into ways of running RasPi apps virtualized in Android and this video popped up in my suggested a few days later, this is literally perfect. As a few folks have said below, for Creality printers that have backpower issues, cover the fourth pin (5V) on the USB-A connector (host side plug, one that will go into the hub or adapter) with a small bit of electrical tape as well to take some of the strain off these older batteries. Have it working now, and I thank you and the Dev behind this app, for putting in great work!

[@amrsoll]

For benchmarking the UI load time over an other browser, I recommend to time it after the login screen. The login screen has been optimised to take the least resources possible. Speaking as a dev who works with OctoPrint on the daily. Great vid and eye opener. Really enjoy it whenever people can repirpose their old hardware

[@MrGerhardGrobler]

Now this was a very useful video. What to do with your old phone once you upgraded to the new contract phone. And no need for HDMI cables to a monitor you are using on your PC. Very nice. Thank you Tom for always coming up with a relavent topic for your videos. FYI, your 18650 battery video. I pay 1.5 Euro's for a brand new battery. So you paying 1 Euro each is a massive saving when you need hundreds of them.

I had several usb connection lost issues with my odroid xu4 running octoprint and I was just about to order a raspberry. After I had seen this video, I hooked up my Nexus 7 (from 2012!) and gave it a shot. It is not only running more reliable now, but having octoprint acessible right next to the printer on a big touchscreen is such a treat.

UI Customizer plugin also gives a better responsive mobile experience for loading the interface on the phone directly and is still actively developed where TouchUI has several plugin conflicts and doesn't seem to be maintained anymore.

[@Gosuminer]

As a returning 3D printer user I wanted to set up octoprint but I did not want to buy new hardware so I installed it on an old Raspberry 1B(!) I had lying around. Everything worked fine, even a webcam, but it was incredibly slow. Inspired by your video I converted my old Xiaomi Mi A1 (Android 9, LineageOS) to an octoprint server and everything works flawlessly and the UI is really snappy. Filip did an amazing job on the Android port, thank you very much for bringing it to my attention. To be honest I kept my old phone exactly because I was thinking about an application like this and I couldn't think of a better way to repurpose my old phone.

But it is actually super sharp and actually 30fps in MJPEG mode.

Dear Thomas. Your explanation is impeccable, very detailed and easy to understand.

[@tamasau8725]

For you and for everyone: I waited a few weeks to write my opinion. After then I can confirm Octo4a works very well for me. I tested it on more smartphones. It worked also on a quite old Huawei P8 Lite. It runs now on a Huawei P20 Lite without any performace problem. I was able to set the energy management easyly. I made an "Y" cable, but it didn't work for either. It is currently running only on battery power. It lasts even up to a 24 hour of printing, or more. With a very used battery!! Especially when I turn off the camera server. I ordered a USB multiport hub. It's on the way. I hope it will work. I don't want to modify the phone with an additional battery charging module. The only one issue to me is about the camera focus. When I turn off autofocus, everything will be awful blurry. With autofocus too, but not as much as when it's turned off. I saw on github this is a current issue. So I'm waiting it will be fixed sometime. Overall I'm happy. I installed a BLtouch sensor. I was really scared to modify my printer. I scared about changing the firmware and losing the SD support too. But everything works fine. By the way my printer is Anet A8 Plus.

[@rigormoritz]

Have you managed to get charging to work with the hub you mentioned? I have a p20 lying around with information regarding simultaneous charge with otg scarce for whatever reason. I'm curious if you got it going and if you did, could you share the model of the hub?

[@zacharyyoung8807]

I've tried this in the earlier stages about 6 months ago, but not much since then. much has probably changed since I used this. It's a great piece of software if you're in a pinch and want to try it out, but don't forget an old PC with an installation of linux can run octoprint just the same (plus there's a longer development trail, so it would be generally more reliable.). Great option though for quick setup (except for maybe designing the phone holder). Great Concept though and I bet it will only get better!

[@SeanTaffert]

Nice vid. Good info. ...I'm a Pixel 5 guy too. I like the reuse of old phones for something practical.

[@TheBoojah]

I run octoprint on a 20 year old laptop, running linux. Works great, it's nice to have a big screen for control and monitoring, but mainly it's just what I used prior to octoprint. A linux install of octoprint is a bit more involved than just running the octopi image, but I had no prior Linux experience when I started and there are guides. You can also run octoprint on windows, but it's not quite ideal compared to Linux apparently.

[@RitoriqPrinciples]

Even two years later this makes more sense over a Raspberry Pi. With a phone you get all you need, the processing platform, a camera, power source, power backup (at least for the OctoPrint instance) and internet backup (WiFi and 4G or 5G). Additionally, in some setups you need an additional display since some displays can't be connected reliably to a Raspberry Pi.

Thanks Thomas for the info! Yesterday I was finally able to convert my old android phone without a battery to a printer support! I've removed the battery, soldered wires to the test pads (fortunately there were 3 of them for each traces!), added a LM2596s module and a 10k resistor as a thermistor. Without a resistor the phone won't turn on. Previously I've tried several Y microusb OTG cables but the phone stopped charging after a few seconds. This way I can use it until the charger is plugged in.

[@adamhun994]

Okay, tried printing a few models now and have some trouble maintaining stable connection. I'm getting timeouts randomly and that causes the printer to pause for a few seconds. Sometimes the motherboard disconnects completely and the printer fully stops. I'm not sure if it's some kind of noise, but I'll check with a raspberry pie soon.

I'm trying something different myself. I grabbed a trash tier Galaxy J3 and made it charge between 40 and 60 percent through software (AdvancedChargingController).
