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 out. That wasn't the worse of it. The worse was the stench that came out of the packing. I can't believe anyone could tolerate that and stick it in a tiny USPS envelope. At least it no longer smells.
In between the horrible pain in my head I've worked a bit more on the sensor code. I have to say, the code is very straight forward. I have found some curious anamolies with the sensor data coming from the accelerometer on the Xtrinsic board. Sometimes the reading is fairly steady and I get the expected 1-g force coming down the z-axis. Then I'll get a blip where there is some factitious g-force spread across all three axes. The next step is to look at the code for the car demo that comes in the install package. There must be something pre-written that handles calibration.
Otherwise, that's about it for now. Working a bit slow, I know the deadline is fast approaching. I will be getting some more extensive time off soon, so I'll have to make rapid progress then. The upside is that it's all pretty much a software issue from here on out.
Oh! One thing that occurred to me is that a pizza delivery bag generally hosts two, three, or more pizzas. How to keep track of all of them if they go to different customers? Initially I imagined that this PizzaPi would be a new and improved box. But then I realized that you really can't replace the cardboard because it's cheap and everyone likes having something to keep the pizza in. You can't really give a special box to the customer, that would be too expensive. So I'm thinking about making one of the Raspberry Pis actually fit onto the cardboard box and act as a tracker, or maybe another solution would be RFID of some sort...just thinking out loud. I'll get this sorted!
I've got to get some rest but I'll be back with another post soon.
