PizzaPi: The Last Day

Posted by dmrobotix Aug 27, 2015
Hello, everyone!   This has been a really fun challenge. I've never entered a design challenge contest before but after doing this one, I would not hesitate to enter another one! It's come down to the wire for me and I have to say that while I am a little disappointed that I did not get the final prototype together to demonstrate, I am excited about what I have accomplished thus far. I do plan to continue working on PizzaPi and completing the prototype. I want to develop it to work in diffe ...
Well, I'm making progress but this iOS app stuff is a little bit tricky! Just about everything I proposed to do on this project I've had some familiarity with EXCEPT iOS apps. In fact, I've never made a mobile phone app but I've always wanted to. I'm glad I'm finally getting around to learning how to do this, but at the same time, it's really challenging trying to learn a new language in such a short period of time.     I decided to learn how to do this in the new Apple language, Sw ...
Back again with another update. I've uploaded another video capture that shows both the customer front-end and some of the administrative front-end. I am almost done building out the UIs for these and then it is a matter of writing the PHP code to link it all together with the MySQL database. Just to refresh everyone's memory, the Raspberry Pi 2 will be acting as both the web server and mosquitto broker. Therefore, all the code I'm writing right now will be hosted on the RPi2. This will be ...
Hello, everyone!   I apologize for being incommunicado for so long. I was sick for a few weeks and then I had to wrap up work at the lab for the summer. Excuses, excuses, I know. Anyway, I'm here! I'll be posting a lot more as we are now in the final stretch.   Part of PizzaPi is hardware, but a majority of it is software and right now I'm working on the web/mobile/tablet interface. I'm doing this using MySQL as my database; PHP, JQuery/JavaScript, HTML, and CSS to create the web sit ...
I've been a little sick this week and I haven't been able to work too intensely on PizzaPi. I did get the parts I ordered. I haven't tested the temp probe, but I'll post more about that soon. The pizza delivery bag was totally disgusting. It did say "used" but I kind of expected at least that they'd wash it! It had a GIANT tomato stain on the inside. After washing it twice, once with the stain inside, once with the stain on the outside, it still remains. I think I will have to scrub it to get it ...
I had a funny glitch on one of my Raspberry Pis this weekend. Somehow the operating system corrupted and wouldn't boot anymore. Luckily it was on the one running PiFace and I have not done much with it so I didn't lose much. I should have probably run recovery mode....but I forgot. Oh well, I wiped the whole thing and reinstalled the various packages needed to run PiFace and Paho (for communicating with mosquitto, the MQTT broker). This was on an older Raspberry Pi, not on one of the new ones th ...
Hello, everyone! Just wanted to let you all know that I won't be posting an update until next weekend. I'm on holiday for the Independence Day weekend (and a few weekdays after that). Looking forward to writing an update soon. ...
I'll have to keep this short because I have to get to bed as I have work in the morning. However, I just wanted to report that I was able to get sensor readings from Xtrinsic MEMS sensor board to be published to the web browser.   The process is as follows:   Sensor board on Raspberry Pi B+ has a python script that handles communication between the board and the computer. This same python script then pushes the data to the mqtt server which is on the Raspberry Pi 2. This is set over ...
HELLO EVERYONE!!!!   After many struggles I have managed to get websockets working with mosquitto on my RPi 2 (Thanks element 14 for this baby).   I decided to start from scratch, so I wiped the SD card and reinstalled Raspbian. I honestly had given up on the idea of using websockets, but I couldn't find any recent tutorials that didn't include enabling websockets so I decided to give it one last shot. This particular install tutorial was helpful, although there are number of sites w ...
Hello, everyone!   Well, I've been struggling to get Mosquitto to play friendly with websockets. Has anyone else tried running Mosquitto with websockets enabled? I posted the following on someone's blog about running the MQTT server on a raspberry pi but it is still "awaiting moderation" so I'm reaching out to this wonderful community for some help! Otherwise, if I can't get it working, I'm just going to stick to the tried-and-true mqtt protocol and pass a text file to lighthttpd. Always h ...
Since my last post I've made some good progress on setting up communication between the various Raspberry Pi computers over MQTT. I got a case in the mail for my RPi 2 and that bugger is now sitting in the living room with a network cable plugged directly into the cable router. At my desk I have the other two RPi's that make up the brains of the pizza carrier.   PiFace CAD is running on my old RPi model B and the Xtrinsic board and GPS module are on the Model B+. Both have their own wifi d ...
The Machine-2-Machine protocol, MQTT, has really forced me to rethink how to organize the whole communication process of this project. MQTT stands for Message Queue Telemetry Transport and is touted as the protocol for the developing world of IoT (Internet of Things). Developed by Andy Stanford-Clark and Arlen Nipper, MQTT has been around since 1999. I heard about it while scouring the Raspberry Pi forum for information on communicating between two Pi's over TCP/IP.   Here's what the offic ...

PizzaPi: Quick Update

Posted by dmrobotix May 10, 2015
Hello, everyone!   Sorry I have not posted much recently. I would be remiss in my contestant responsibilities if I did not keep up with my updates and give a quick heads up on how things are going with PizzaPi!   Last week I started my 10-week full-time internship at the lab I work at and its been a bit of a challenge getting used to working all those hours! I'm actually spreading these 10-weeks over a 20-week period, so in a few weeks I'll be off again and I'll be more active around ...
So the parts list for the kit online included the base board for the Microstack GPS module and accelerometer. However, the kit that arrived at our doors does not include the base board and it seems unlikely to be arriving anytime soon. My GPS module arrived today and I really wanted to get it to work so I had to get creative. I took a good look at the user guide for the Xtrinsic Sense Board (and the board itself) and noticed that there are some pins sticking out on the top and bottom sides o ...
Hello everyone! Well, it's been a busy last couple of days for me. I've been struggling with the Xtrinsinc MEMs sensor board because I cannot seem to get it to work with the Raspberry Pi 2. I believe the problem boils down to a sensor driver that is not compatible with the Broadcom chip. Raspberry Pi 2 has the Broadcom BCM2836 chip whereas all other models run Broadcom BCM2835. Has anyone else had this trouble? It works perfect on the B+ which uses BCM2835. I even tried the image that is on the ...
