    I'm not up to speed on the absolute latest in versions of the Pi, but I tend to always buy Pi 3's since the price difference isn't that big. Any reason not to just default to the highest performer?

    Quote from bobbydilley: “Thats a pretty good price - would you have to solder everything on the board yourself? Thats always the off putting part for me! ” Yeah, the cost is just for raw components. I did design it with through-hole components, but no way anyone is going to pay me as much as my day job to solder them up and make it worth spending my free time trying to sell them. Quote from bobbydilley: “Thank you - Ive looked at lots of other projects such as MegaJVS when writing it and so it w…

    Quote from bobbydilley: “@winteriscoming That is very cool! How much does the whole board cost? ” I must have missed this question. The BOM is pretty low. I had a few boards made by pcbway, which is very affordable for small runs, and bought a small bulk of the individual parts to be able to populate several boards. I'm not sure on exact cost for populating a single board, and it's been a while since I looked at pricing, but costs are probably about $25, not including the Arduino and screen whic…

  • Is there anyone willing to pitch in on a set of SD cards or hard drive to physically mail around? I don't have a worthwhile collection, so someone who does would need to volunteer to start it. We could get a list of interested members together and do a mail relay from one to the next.

  • I picked up the SNES Classic over the weekend and added some extra stuff. I had a hard time with non SNES games initially. I didn't look into the different Hakchi versions prior to starting and had to start over with the latest CE version and got NES and Genesis working. The bad thing is that I also started messing with Retropie on a Raspberry Pi 3 and wish I had just skipped the SNES Classic. It's so much easier getting stuff to work on Retropie and you've got easier access to expanded storage …

  • FYI for anyone with spare cards around, I was able to get this running on a 2GB micro SD card using the directions above.

  • I was just looking at resource usage for mjpg_streamer running this way, and it's super low. The highest I saw it go was 1.3% CPU usage, with a webcam. I fully expect that this could run along side netbooting and the card reader script. I haven't yet tried running the card reader script on the RPi myself, but others have reported success. I would imagine it's not too resource intensive either.

  • DIY directions: Things you need: Raspberry Pi 3 B+ (that's what I'm using - could maybe be another version) Micro SD Card (not sure on minimum size - mine is 32GB and way more than enough) 5v Power Supply (I use a 2.5A Canakit one) Webcam or Pi Camera (I'm using a Logitech C615) Download a linux distro for RPi. I used this one: downloads.raspberrypi.org/rasp…raspbian_lite-2018-04-19/ Load it onto the SD card. Once it's loaded, mount the card in your computer and write a file to the root folder a…

  • I've managed to get this solution down to an even simpler setup! mjpg_streamer has its own webserver and you can specify the port when running the program, so it's easy to set it up to port 80, which is what Mario Kart needs. mjpg_streamer requires that you pull it from git and compile it directly on you RPi to get it installed. One of the options you can set makes the program serve up a still if you access something like ip/cam.jpg. I figured out where this name is specified in the source code …

  • I did get the Pi camera working with mjpeg-streamer, but it's definitely not as good as the webcam I'm using, and I'm back to running into frequently unusable jpegs being posted, which basically kills the framerate of the camera in-game. It's just a difference in one line of code, so I can probably put together instructions that would include either option. I'm thinking the webcam is going to be the way to go because they're easier to mount, can make use of an easy-to-acquire USB extension cable…

  • Ok - I might be back to preferring a webcam over the picamera, but I will have to do more tests to see if I can get similar performance from the picamera. Using my better of 2 webcams, I made use of mjpeg-streamer to set up a live stream of the webcam, and this comes with a static capture. I then scripted something to copy this over to ip/img.jpg and the quality and refresh rate are phenomenal!

  • Quote from obcd: “Maybe it's a bit logical that writing and reading a file simultanously will cause issues. A solution could be to have 2 images and present the older one over http when the newer one is written. At that moment, you can switch images and overwrite the unused one. ” I'm not sure I have much control over it. Depending on timing, the game could be accessing the image at any point it's being written. I did start writing to a temp file, and copy that over the file that is read afterwa…

  • Quote from Solkan: “Can you tell me more about this ? ” The PCB is screwed into some built in stand-offs in the metal casing. The goal is to get something non-conductive that is just slightly taller than the stand-offs that, when installed under the GPU, will push the PCB up slightly, hopefully making better contact with the flaky BGA connections. Certainly putting something too tall in could cause the PCB to break or make the BGA worse. This is by no means a trusted method. I just happened to b…

  • I ran some updates on my RPi in an attempt to get quicker and better low light images, and now my script that was successfully running seems to be posting unusable jpegs. I'm not sure why it changed, but it's like now when the browser or Mario kart access the image, it's often not working. My browser will complain that there's an error with the image and MK just won't show anything until it gets a valid image. If I spam the refresh button, I can sometimes get a valid image in my browser. It's as…

    Will this run lag free on a stock linux distro or will it require something more customized? I'm just curious if the RPi can handle USB host to JVS translation in a lag free way with a stock os. It may well be able to. This sounds similar to @invzim 's JVS project. I wonder as a community of arcade project enthusiasts, do we support every project, even if one comes up that might overlap with the goals of another established project? Without inciting drama, it's just a debate that may be worth ha…

  • Quote from freddiefiasco: “I vaguely remember playing vs 4 other people and during gameplay, whenever I was near another non AI player, their cart would show their face from the camera at their cab. I can't recall if this as GP1 or GP2. AI players would have the toons image in place of the camera. ” You're thinking it was a real-time stream of the player and not just the static image they took when they started? It's very possible, but I I'm not set up to see that in my tests, so there may be so…

  • I briefly tried the stock camera board and I notice that the game during test mode refreshes pretty quickly and the camera does pretty well in low light. I can get similar speed from the picamera by running it from python, but I haven't figured out a good balance between good low light performance and speed to match the stock hardware. At worst the speed will have to be sacrificed for a better image. This wouldn't be too bad, though, since you're really only using the live feed to position yours…

  • What is the point of the original board? It looks like it's just a pass-through for everything.
