This is designed to be a DIY, no certification has been done on the plastic, it will be whatever 3D printed plastic is used. If someone wanted to turn this into a viable product for wide distribution, I'd be happy to help! A food safe injection-molded to stainless steel lid with integrated housing for sensor electronics would be the next best step for this project.Have you guys done anything to use and or certify that you use food grade plastic in the enclosure? It sounds like most people on this thread don't seem to care about that, but if you ever want wide distribution you will have to get some sort of certification that the plastic is of food grade quality.
Actually none of those believe it or not... Just got home from the hospital, with my wife and our first baby boy! Sorry for the delay in support, thanks for helping out @LBussy!
You do not. The calibration coefficients are stored in EEPROM, and won't be affected by this firmware update. By default the averaging interval will be 300 seconds after you update, so it will still behave as it did before, you just now have the option to modify the interval from the web GUI.If I upgrade the firmware to 1.5.0, do I need to recalibrate the levels and pressure?
Yes, you can build a Flite lid with ONLY the time of flight sensor. It will still function without the integrated pressure/temperature sensor.I'm going to build one of these, but I'm not sure that the temp/pressure is worth the $38 that Digikey wants for it.
I understand that the whole thing is a really cool "unnecessary" gimmick, but do you guys really like seeing temp/pressure?
Will it work if I just don't wire it in?
I was able to find 2L parts on amazon, but it looks like they are out of stock at the moment. There are a handful of food grade epoxies out there. You can add a little food coloring when mixing if you want a color other than clear. Let me know if you have any other questions!This looks like an awesome project. Where did you find the ZDSticky Epoxy? Currently I can only find 16oz kit on Amazon and it is clear. Was hoping to get larger capacity jugs to build 6 of these.
The longest cable I have from my main controller to a Flite Lid is roughly 5ft. I have not experienced any issues so far.Quick question @Schauby7, have you experienced any issues with I2C over wires?
My application also requires a single controller for at least 3 different Flite sensors, but considering that I2C was not designed for long distance communication (in my case 5 - 10ft) I've been thinking of using RS232 or RS485 instead.
Thanks for the help and cheers for the project!
That's easy: Your stuff is working too long in between re-builds. Re-arrange and completely gut and replace your fermentation and serving chambers every 3 months and you will no longer have those issues.in the past I've had issues like that when putting permanently powered electronics inside my keezer.
