Description


Named after an exquisite high flying feathered friend, our Black Kite altimeter is ready to fly straight out of the box.
What's more you can further develop or tweak the software should you choose! Although the included base software has tons of features already.

Instructions

Ready to fly, straight out of the box!

If you fancy making your own altimeter or flight computer and want a basic building block then this is for you!
Likewise if you're just after a great altimeter that records tons of data for you to download over WiFi with ease later then this is also for you. 
(No programming is necessary it is a working product out of the box)

The altimeter comes in a open top 3D printed box to protect the board and battery while still letting you access the altimeter if you are developing it further.
You can remove the altimeter from the case and mount it in your electronics bay if you prefer. 

Dimensions and weight

While in the case the dimensions are 68.8mm overall length, 27mm at the widest point where the battery plug is, and 14.5mm maximum height.
The case is only 12mm high and 53mm long excluding the mounting holes.
The altimeter weighs in at 14.4 grams in it's case.

If you remove the altimeter from it's case then it will measure just 52.3mm length, 22.9mm width and 13.4mm in height from the base of the battery to the top of the battery connector. 
The altimeter weighs just 11.1g out of it's case. 

It's a data logger too!

The altimeter is easy to use and records the last 4 flights of up to 10500 samples on each flight. Depending on the samples per second you choose this can record 4 flights of up to 10 minutes each.
The data from each flight can be downloaded from the WiFi admin panel in CSV format to either a phone, tablet, laptop or PC to create charts. 

After each flight the device will show you a summary of the maximum altitude, time to apogee, and maximum velocity upwards and downwards.
You can of course look at much more information using the CSV files after the flight should you choose. 

High accuracy
We let you set the local forecast pressure in the altimeter prior to launch, this allows the barometric pressure to be read incredibly accurately. 
You can set this from the WiFi admin panel along with other settings as well as directly on the device when you turn it on. 
The BMP280 pressure sensor is a great accurate sensor.
We tested the altimeter on a DJI drone to a GPS altitude of 120 meters, the Black Kite altimeter reported back at 120.1 meters for example. 

WiFi admin panel

You can connect to the devices WiFi and then visit the page shown on your device to access data and edit more settings.

The admin panel lets you control settings such as:

Forecast pressure
You can view your local weather forecast for your launch site to find an accurate pressure to enter.
This lets the altimeter know roughly the actual altitude it is at above sea level and give a more accurate altitude reading. 

Launch detect height
This setting tells the altimeter when to start recording.
The altimeter will watch for a rapid altitude change, and once it exceeds this setting it will enter record mode.
We suggest 5 or 10m as sensible options here.

Sample rate
Three options are available for the altimeters sample rate.
32 samples / second: This is the default setting and lets you record for 5 minutes at this rate.
16 samples / second: For longer flights this setting lets you record for 10 minutes.
Hybrid: This lets you record at 32 samples per second for the first minute before dropping to 16 samples / second for 9 minutes total.

Recording stop method
By default the altimeter will stop recording when the altitude no longer changes for 5-6 seconds suggesting it has landed.
You can turn this off and require the button on the altimeter to be pressed to stop the recording if needed. 

There is also a QR code to scan and read the altimeters manual on another device if you need while at the launch site.

Internal Rechargeable 220mAH LiPo battery

Our altimeter has a rechargeable LiPo battery. Just plug in a USB-C cable to charge your device. (not included). 
This battery gives around a 2 hour "on" time for the altimeter. Wifi mode uses twice the power so you'll only get just over an hour from full charge if you turn WiFi on.
Charging however is fast and only take an hour should you need to top up!

Development mode
Should you want to tweak how the altimeter works, customise it or turn this into a project of your own then you can.
With each purchase you will get access to the source code file for the current altimeter software.
You can use Arduino IDE software to program the Altimeter. 
This altimeter is a very powerful device and can do much much more than our altimeter already does. You could make your own flight computer even.
There is a onboard STEMMA QT port making it easy to add extra sensors or output MOSFET's for example to fire electronic igniters, or control servos (a servo controller may be required).
The included code should make it easy to get the grips with the board and learn to use the ESP32-S3 chip on the altimeter.
Both Bluetooth and WiFi are present on the board.
