Battery Pack and On/Off Switch
05/25/2017 at 19:50 • 0 commentsI have found a battery pack and an on/off switch that I like. I'll probably need to wait until next payday to get them.
- Battery pack - USB battery pack for raspberry pi 4000 mAh 5V @1A
- On/Off Switch - USB cable with switch

Camera might be broken on the raspi.
05/23/2017 at 20:42 • 0 commentsWhile 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.

Touchscreen installed!
05/23/2017 at 20:39 • 0 commentsI 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 :)

Hiring 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...

Choosing a screen and a AA battery pack.
03/31/2017 at 20:03 • 0 commentsCurrently 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.
