Lua Pi Pan

Iv been crazy distracted playing with my new 3d printer but iv been working on some updates and error fixes that are on the main git page now. I'm working on a tempature overload shutoff using a 1wire temp sensor and a relay for my 3d printer that will also take progress photos and email them to you while its printing so you can shut it down remotely if a print messes up.

Spent the last week updating the vast majority of the code in order to remove as much of the hard coding from the objects as possible. Now that its done its much easier to add new objects! Also did a number of fixes so everything should run more smoothly.

Iv gotten my 3d printed fish feeder up and running. Still needs a bit of work to get into action feeding fish but here is a video showing it dispensing food. The code for the feeder is on the projects GitHub as well.

Iv 3d printed up some PIR motion sensor housings with ball joint and cover so i could weather proof my sensors a bit and protect them from possible stupidity. They fit perfectly and im really happy with the final product! Here is a link to the file if you wanna check it out.

I should have the remote module for stepper motors up tonight as well.

Iv got my stepper motor module working rather well! Soon as I finish the design I will work on building a fish feeder. I'm going to get the remote object set up for it next but iv been distracted 3d modeling and printing a cover for my motion sensors, soon as I get my 2nd design test printed I will put up the files for it. Also working on a higher amp version of my relay box so I can use my heater on a higher setting then low. I will do a video of that soon as well.

After I found out the rpio library wasn't doing the trick for reading DHT22 sensors I finally took the dive and started learning c. Took me a couple days to get enough down to figure out the Lua c API and write a wrapper for a c function that uses wiringPi to bit bang the sensor. As a super nice bonus it works waaaay faster but it does require Lua pi pan to be run with sudo if its being used with the DHT22 module. I'm very tempted to write a full wrapper for wiringPi and switch GPIO libraries again to take advantage of the reading speed...

The source and .so file are on GitHub page if anyone wants to check it out.

Did some minor code updates, I figured out that the DHT22 module no longer worked due to the change in the gpio library used so im working of fixing that now. Iv also made a new video showing how to configure a master or slave node.

Getting better at making YouTube videos! I did a video of hooking up a relay and 1 wire temperature sensor to a rpi then configuring it to work on a thermostat.

I updated and cleaned up the code on GitHub. I switched from the lua_gpo library to the rpio one. It required a bit of modification to get working well but now it seems to be giving me faster reads then the old library. Also it should be compatible with the RPI3 which was something lacking with the old library as well, I will test this out tonight. I have my branch of the rpio code on my GitHub.
