I like learning and trying new things. Most recently, I have been working with radios, and have obtained a licence to operate some [RPAs](https://en.wikipedia.org/wiki/Unmanned_aerial_vehicle). So, obviously the next step is *space*, right? As I am entering this with near 0 experience, I'm going to start simple.
|
|
|
|
## Design
|
|
My first satellite project (named [Spike](https://github.com/Ewpratten/Spike)) is designed to do the following:
|
|
- Be deployed in [LEO](https://en.wikipedia.org/wiki/Low_Earth_orbit) by a [cubesat launcher](https://en.wikipedia.org/wiki/CubeSat#Launch_and_deployment)
|
|
- Be solar powered
|
|
- 24/7 data is not required, so the device may go dark
|
|
- I may look into an on-board [LCB](https://en.wikipedia.org/wiki/Solid-state_battery) for night operation
|
|
- Record temperature, and light levels
|
|
- Stream data down to earth
|
|
- Burn up in the atmosphere
|
|
|
|
I am currently working with the following parts to build a grounded test device.
|
|
- [Arduino pro mini](https://www.ebay.com/itm/New-Pro-Micro-ATmega32U4-5V-16MHz-Replace-ATmega328-Arduino-Pro-Mini-/221891843710)
|
|
- [315mhz transmitter](https://www.sparkfun.com/products/10535) (This will be replaced)
|
|
- [A photocell](https://www.sparkfun.com/products/9088)
|
|
- [A TMP102 sensor](https://www.sparkfun.com/products/13314)
|
|
|
|
My goal for the grounded test device is for it to survive ~14 weeks of un-attended operation, and some temperature tests.
|
|
|
|
## Current progress
|
|
Currently, My testing setup consists of the following components that I had lying around:
|
|
- Arduino pro mini
|
|
- Photocell
|
|
- [lm35 sensor](http://www.ti.com/product/LM35)
|
|
- Buzzer (To emulate a radio)
|
|
|
|
|
|
|
|
The board has been "transmitting" telemetry data for over 24 hours now.
