If you used the latest version of raspbian please roll back to the 'buster' version. Bullseye broke this software

Yeah! I need to revisit it and see if I can automate some of the capture...I'd like to pull this into Unity and then VR next :)

sorry got locked out of my account, just seeing this. please try this tutorial..basically you're going to rotate the entire display: https://howchoo.com/g/nzvimjk0nme/raspberry-pi-display-rotation

All right! That's definitely progress! And I'm glad you figured out customizing it...that's one of the best things in my opinion...when this Covid stuff is over and you can show your website on the tablet to friends with your own theme it's going to be awesome!Lets see if we can take each thing step by step:1) Do you have a cell phone wall charger or something you can plug the feather huzzah into to see if it's just the cell phone charger pack? Some have auto offs, so that might debug if a different cell phone charger pack is needed. I've noticed with recent ones that is alot more common than the older ones I've used.2) Please try connecting to http://10.10.10.10 in a browser once connected to the wifi and see if the page comes up and stays.

It should be as simple as connect to the wifi network, and then you will likely get a 404 'page not found' if the DNS stuff doesn't work...then simply go to http://10.10.10.10 and lets see if that fixes it for the phone/laptop scenario3) The ipad may be switching because it detects that there is no internet when connected to this device. I'm not sure if there is a setting for that...may have to disable autoconnecting to the main wifi (or may have to tell it to 'forget' the network, then when you reconnect do not check the 'connect automatically' box if there is one.Since you got a speed reading I think you're really really close, that should mean that the sensor is hooked up and working. I'm super excited and will do what I can to support you, please let me know if you hit any issues and we'll work through them. I'm following my instructables feed much closer to stay better on top of it (I didn't have a message for months so I got a bit way from it).

Hey there! It just needs to close and then it should open. I believe the term is 'momentary switch'. I was using just a button to do it, but any momentary switch system should work, and that was one of the design ideas I had so that others could do much more creative 'starting' systems

I'm going to take a look at making a version of this that either fixes the dnsserver error or removes it. I'll work on it tonight and try to get you and the others unblocked

I went back through this and realized the DNS server is how I'm doing the connectivity portion. It'd have to be re-written entirely to remove those. If you're just trying to get up and running, I've re-written step 4 of the instructable and that should help immensely...open the .ino and the arduino ide will ask to create a folder. Once that's created, move the two dnsserver files into it, and you should be good to go. Since the DNSserver code doesn't obstruct anything, I'd rather keep it in there. Is there a reason you'd like it removed, or was it just giving you issues compiling?

Ok, I think I see what's going on...I did a terrible job in step 4. I've updated it with much more info. Basically when you open the .ino file arduino should prompt you to create a folder....when it does you'll want to move the dnsserver files into that folder, and then things should work. Step4 has been updated to help out as much as possible now so that programming it from the start should be more straightforward.

Thankyou so much for this, that's a great update! Yeah, I'm working on trying to figure out what the best way to update this would be....one thing I like about it is if the network on the device goes down it still works, so if you were to say load it up with pictures and send it to someone it'd work fine. But there's something about having it load files from a share that would be powerful as well. I'll have to think on that as I design the update. Right now I'm working on a better, more reliable slideshow that does actual fades and such

I would look at the logs in cronlog and try to see what playlist it's choosing. it could very well be a file that is crashing it. I had found a bug that involved underscores in files causing issues for Feh. So I'd go through the file names, look for anything odd, and try renaming those files. Let me know how that goes. I'm working on fixing the bugs, but the coronovirus has me making face shields with my 3d printer and keeping me busy helping the community so this has fallen to the wayside sadly

The ESP8266wifi I believe came down when I selected that as a board. For an arduino uno wifi the code may need to be redone a bit, as I was using libraries that were (I believe) specific to the 8266. I think the options are to get the same chip I had (I believe it was a huzzah feather) or to adapt the code (ones easier/spendier, but adapting the code would be a good learning experience if you ever had to change things in the future...and with an 8 track lane, you definitely will). I honestly would take the code I have, learn the basics of the arduino wifi hosting a webserver, and then shim in the code I have piece by piece. You'll find it's fairly simple to rebuild, and I think it'd be a cleaner way to get things going.Option 2 is to buy the feather and then flash and go. Let me know wh…

Let me know which way you want to go though and I'll help you out...I'd love to see an 8 lane track with this setup!

I don't have a closer one, I'm sorry. The wood work was done by Dan, I'll see if he brings it out during the holidays and I can try to get some pics if I see him then, but it may be a bit. If I were to do this again I'd probably look at making an automated starting gate that was servo driven however, as I think that'd be a cooler 'start'. We just were working long distance and it was tough to plan, so I never figured out how to do that in time sadly.

.gifs aren’t supported out of the box yet but we could work together to figure that out. It’s running command lines so we just have to find a command line gif player. Similar with the 4:3 portion...it may just work as is, if not we can figure it out. I’ve been meaning to dust off the code and get an update out. This will be a great opportunity :)

I don’t but I’m working on it. I research apt get but that wasn’t viable. I’m going to have to write a bash script that installs dependencies and then should have something usable. I’ll work on that this week. If you’re good with rpi, then snagging the python from github and pip installing anything it complains about will get you most of the way there

Excellent!!! Sorry for slow replies been busy working on my makerspace (and I have a 1 year old, she keeps me busy :) ). I’m going to try to get animated gifs working and see if I can make a bash script to ease installing this. I am just new to Linux and am not sure how software like this gets distributed...apt-get is maybe the solution but I think I’d have to host my own server.

Nice!!!! I think you’d need a form and button in html for the webpage. The button should send a get request of some string like “start”. When you hit the button you should see ?start= get appended to the url. Then you’ll want to look at where the http request comes in and parse the request string. I won’t have time to load up the code for a few days but am hoping to for another question. Hoping that gets you on the right track

I’m not sure it’ll take me some time to load up the code again and refresh myself. I’d try just deleting the header to start. If nothing else I don’t think it hurts being there unless you’re trying to save code space. Keep in mind it’s only acting as a DNS on the private adhoc network that is created when something connects to it

Ah here ya go: http://www.martyncurrey.com/esp8266-and-the-arduino-ide-part-2-control-an-led-from-a-web-page-using-access-point-mode-ap/

The 3 is fine for this. If you make the finish line over a foot tall for the gap I’d consider 5mm though

You definitely don’t have to have it! I did that for ease of use...it makes the WiFi portion a captive portal. So if someone mistypes the ip it’ll redirect them. I didn’t think it was user friendly to have someone have to memorize an ip, and if using this on say a smart TV it’s a pain to type an up. Feel free to remove it! Hope that answers what you’re asking about

OMG that’s beautiful!!! I haven’t done step 7 sadly, this project is at a friends house far away. I plan on building another and doing those steps but that may be a few years out. I have a daughter now that has both inspired me to do it but also keeps me busy! I love the pivoted view and am glad to see another build!! I’ll definitely post here when I update it, but I’m the meantime if you want to tackle any of those and need help I can do what I can to assist

You could definitely use a pi2, as it's just doing image/video slideshows. I think the main thing is you'd want a wifi connection added on to get alot of the benefits of this setup, as it provides things like remote adding of files and management/playlist selection. However I don't believe my pi3 image will work on a pi2, so you'd have to start from scratch (not terrible, thats why I wrote this instructable to walk others through it). If your python skills are up to the task it shouldn't be too bad.

Yay!!!!! That made my day! I write these in hopes to help others so to hear that it helped is great! Also WOW that’s a beautiful project!!!! I love the brick designs and ...well everything. Well done and glad it helped you!!

It should be, though I don't know if the premade image I have will work on a pi2. The code from GitHub should work as it's merely python. I believe the pi2 could play 1080p video just fine, so it should be a good project for it!

The program as written won't work with it, simply because it hosts a webserver using the built in wifi of the huzzah. You could potentially adapt this to a D1 WeMo (I believe) or another 8266 based microcontroller. If you only have an Arduino, but understand it well, you could adapt the code to output to say a small screen, or seven segment displays.

Oh I see what you are saying...it’s a good question! You only need the huzzah feather. I used a Stock photo to show how the sensors hooked up which I see now is confusing!Just hook the sensors to the feather and you’re good to go!

WOW! That came out looking amazing!!! I do these in hopes of helping others, so to see that really makes me happy and inspires me to post more things. Very well done and great job!

This one is about 5.5 inches. I purposefully kept it small for this project...there are a ton of bigger ones out there, so I wanted to do something differnet. I do have a large one I'm working on, but to make it different I'm adding quite a bit of functionality to it. The next one I do will likely be this size though, as I find it works out well as a 'side display'. We'll see!

I definitely will! I’m likely going to do a laser cut wooden one with a raspberry pi a+ at some point but honestly I’m probably six months out as I’m not in dire need currently of another (yet!). I’m working on some cool data sources first that I’d like to have the mirror display :)

Hi Thankyou!!! So the camera's not doing a great job of showing it, but what you're seeing is the backlight of the monitor coming through...it's actually 'white' but looks bluish through the mirror...on the webcam. So the problem is more of a dimming the backlight to hide that effect vs. a color change. The good news is that it IS possible to fix...the monitor I used (the Kuman) has a button to change the brightness by 10%. The downside is the text gets a bit dimmer as well, and wouldn't have shown up on film as well. For 'in real life' it works fairly well. I'm looking for a tinted plastic or something I can put between them for my next version to try to increase contrast...which is really what you'd want to fix that bleed through. Glad you enjoyed the instructable!

This is...insane. Mad Scientist insanity. When I saw the preview and the title I thought it was click bait. Then to find out you did a DLP/SLA resin style printer inside of the FDM, and you hadn't even seen a resin printer and STILL pulled it off....I could see your excitement in the video....absolutely amazing. Subscribed, liked, and will be following. I also checked out the tv you made a year ago, and that was a sweet project as well. It was neat though to see how far you'd come with editing and filming. Keep up the great work!

Wow..just..wow. I've always been a huge fan of Aliens, and the power loader. If you'd asked me how to build a cosplay of it, I wouldn't have known where to even start...this tutorial is incredibly well written (and entertaining to read!) and I really like that you encourage makers to feel their way through. I've been at that point where you're in a mess in the middle, wondering how to complete it, and so I felt myself nodding my head as I read. I also like that you had a followup Con and had improvements...that makes this incredibly more valuable as it points out gotchas for other projects. Thanks for the time for this and the great instructable, and congrats an a truly epic cosplay!

Yeah, we actually talked about adding a high score section, and it's on my 'todo' list :) We were just wanting one for the session, but to persist it there is a way using the EEPROM (You can store a very small amount of data in it, but a high score and a name should be perfect). Here's an example from GitHub:https://github.com/esp8266/Arduino/blob/342c4ae6fb847bfc787f80b89a2bb888d942dc32/libraries/DNSServer/examples/CaptivePortalAdvanced/credentials.inoIf you add the microSD card, then one thing I think would be really sick is to be able to store web pages onto it. This whole setup serves a website, but to do images I had to use base64 encoding, so the website couldn't be as fancy as I may have wanted. With a microSD card that MAY open up a lot of possibilities! Also a high score tab…

This project really could be modded in so many different directions...race heats, bracketing for tournaments, etc. I got a sizzle video up, with a second uploading, but it won't finish for a few more hours. But I tried to make the one I upped fun :)

Thankyou! I’m working on an update tonight to add a video of it “end to end”. Just need to get where I can upload it :)

Amazing work and amazing results! You got my vote. I appreciate the links to the software and the lights, much less expensive than I imagined. Also the mapping software is super cool to know about. Great work!

Awesome project and great write up! Also I like that you found really inexpensive sources for things...that ikea frame is inexpensive but looks so clean! Well done, you got my votes

Thanks! I'm really learning as I go, and was worried about what I'd do if one of them died. I was trying to do a modular design...and the wire nuts were the outdoor/waterproof type (with the silicone in them). Heat shrink really feels like the way to go going forward, I picked up a heat gun and will practice a bit to get a feel for it. I appreciate the suggestion and knowledge!

Super well done project, and great instructable! I LOVE the added touches...the cargo net, the pulley system...things like that, I feel, really add to a project and make it magical, especially for kids! The only thing I would've wanted more is a periscope, though I have a feeling that's tough to do, and keep watertight. Thanks for the time put into this, and congrats on a great project!

This is super cool! I like how you used the fenceposts for the walls, lit it with solar, and the heater is really a cool idea I'd never seen before (how well does it work? it seems that even if it's not terribly efficient, it'd be super relaxing and a nice ambiance!). Also, great video! Super fun, and has a lot of neat ideas. One last thing I liked..this seems like it's 3 or 4 instructables in one, but I appreciate that because it all ties together so nice (the heater, the table, etc). Well done!

Absolutely awesome! I was looking for a solution like this for an arcade build I want to do...arcade games typically use either a vertical (pac man, galaga) or horizontal (street fighter, ninja turtles) monitor setup. So a rotating monitor is a slick way to play both types of games...but yours with the thin profile and the keyboard /mouse portion (I'd probably mount my joysticks there) would be super slick. The sitdown/stand part works for the arcade portion as well...I just need some time, but now thanks to you we have the knowledge!

That is super slick! Great use of neopixels...I liked the fire effect as well, but this one edges it out...voted, and may the odds be ever in your favor!

The leds are from adafruit...they're called neopixel rings, and I chose the 12 LED versions (https://www.adafruit.com/product/1643). You'll need an arduino to drive them, and a power supply. An alternative, if you're not into doing electronics and programming, could be to find RGB light strips (Like: https://www.amazon.com/RC-Changing-Waterproof-Flexible-SMD5050/dp/B01EFEUZPQ/ref=sr_1_1_sspa?ie=UTF8&qid=1507706273&sr=8-1-spons&keywords=rgb+light+strip&psc=1) and running that under some glass blocks.

One thing to be careful about dropping the blocks is that rain can puddle in that depression...I have that problem with one of mine that is mounted slightly sideways. The lights, with the diffused spray, don't radiate so much, they just kind of glow, at least in the way I've implemented mine.The lights on the side though...I really like that idea! That would handle loads better, be easier to maintain (when a light had an issue with mine, I had to break the mortar to get the block out!), and also make it so you don't have to cut through the paver base. I think if I had to do it again I'd at least prototype that approach...great idea!

Hi Alexandra! Sgbotsford had a really good idea of doing lights along the sides of the path, above ground, and then covering those with wood/brick/mortar/etc. I think that approach would work well for you. The neopixel LED's are contr) ollable with one pin of an Arduino or Raspberry pi (or you can do two separate fstrands if you want to do one down each side). I think you could get a very similar effect to what I achieved as far as lighting it up in colors, and showing off the terracotta! I had to do a lot of soldering and such to bury my wires and space them out for blocks..if you're doing a short run and want to save a ton of soldering/waterproofing, you could look at just going with a neopixel strip (https://www.adafruit.com/product/2842) and then putting the crafting work into cov…

Oh my gosh, thank you so much! You made my day, and have inspired me to work on more cool things :)

The funny part is I thought it was a weekend project :D Three months later....(I did work on it on weekends only mainly, but it definitely took ALOT longer than I thought). The tiller was a huge tool to help move things along
