While I was installing the touchscreen I felt an ever so slight prick when my finder brushed the camera slot. So, that may have been a zap and the camera may now not work. I need to get some static safe wristband thingies.

I settled on using the Wave Share Spot Pear 3.5" resistive touchscreen.
It does not work out of the box because the default setting on a raspberry pi is to use the HDMI port as the video out.
The users manual for the touchscreen has instructions, but they skip over the step of how to install the drivers.... which was a difficult step for me. So I found this wiki linked from the manufacturer's page which helped a lot with the step by step instructions on installing the touchscreen drivers. waveshare.com/wiki/3.5inch_RPi_LCD_(A)
Anyway, I now feel incredibly proud that my project is back on track :)

One of the possible implementations for this project includes linking a database of pre-recorded phrases to a web interface. I have found an actor who is willing to donate their time free of charge to record the necessary audio files. Here is the list of phrases the actor will record for the project.

In order to create an attractive set of icons for the touchscreen interface I am looking to hire an illustrator. I posted to fiverr and have found someone whose style will be good for a product that is intended for children. I need to come up with $265 to hire this illustrator, so I am working on coming up with that capital. Here is the request that I posted to fiverr...
"Set of 53 icons with white backgrounds. Name tag, house, phone, birthday cake, finger pointing at you, fireworks, wizard, train, bridge, one jar, stack of jars, dog, green light, drink, apple, treasure chest, bed, knot, girl, boy, group of friends, sheep, rainbow, mountain, bathtub, bucket of water, bucket of water spilling, spilled bucket of water, a dog and cat, sports equipment, child playing with toy car, one hand giving another a present, person pointing to themselves, theater masks, book, stop sign, money, hammer pounding a nail, sunshine, dice, hand holding a cell phone, person reaching for a TV set, umbrella, scissors, two hands making the sign for "more", school building, tablet computer, "this belongs to" tag, two friends side by side with their arms around each other, question mark, bucket of water labeled "to", person carrying a bucket and paint brush, two arrows going around in a circle."

Currently comparing the two touch screens I have to see which will work best for the project. The two screens are:
- Tontec 3.5" screen model #MZ61581 which requires an install of Raspbian Wheezey or Jesse so I would need to change from my current Debian install.
- Waveshare Spot Pear 3.5" RPi LCD (A) V3
Both screens are resistive touch because that is what I had on hand.
I am also considering ways to implement the battery pack. There is a nifty device called BattBorg, but it uses IO pins and that might interfere with the screen install. I will get the screen in place first then move on to battery pack choices.
