#spidr1090

### TODO
* change plane history from fixed array to linked list of planeObj, handle cleanup
* status box layout system
* status box tap for info
	* trails w/ altitudes
* menu system (toggles for UI elements)
* map system (automatically load open source)
* separate fully from view1090 (which interface?)


###HARDWARE

best option seems to be pi4 + pijuice zero (w/ rewired  i2c) + hyperpixel 4. RTLSDR  (stratux) sticks down or needs u shaped adapter.
For future tuner, need to test audio phat w/ little speaker, i2c knob, etc.


Notes:
Pi 3b+ and below are a little underpowerd for unoptimized map drawing
Pi 4 is smooth, may have USB issues with RTLSDR?
Up squared is good, but large
Up Core may be fine but bad connection options - try up core?

PiJuice is by far best battery option. FCC/CE certified!

Need to test stratux low power dongles. 987Mhz?

Waveshare 4.3" HDMI(B) is very good, slightly too large for handheld. Uses a lot of power, around 500ma
Pimoroni Hyperpixel 4.0 is the right size, but takes over default I2C pins so conflicts with PiJuice, unless some pin remapping. Also lower power, around 150ma
Adafruit PiTFT 2.8" capacitive touch is ok, but a little small. Not sure about power draw. Docs claim no multitouch?

####Battery Options
(https://en.wikipedia.org/wiki/List_of_battery_sizes)
Portrait Orientation:
18500 Batteries (18mm x 50mm), ~1000-2000mAh ea.
The Pi Zero configuration consumes are 500mAh

Landscape Orientation
18650 batteries (18mm x 65mm). ~2200-3500mAh ea. 
Adafruit pack + PowerBoost Charger, ~$40
Anker PowerCore 10000, ~$25

Other options
external recharger (maybe cheaper and smaller?) along with 18500/18650

Some 18500 / 18650 include current protection inside, such as:

otherwise would require external protection circuit to be used in parallel. 



####Pi 3 Version
This gets you a slightly bigger screen, and slightly better performance using the SDR Smart rather than the Nano 3, but requires a ton of annoying port/header clipping and desoldering.
