Meer informatie over de camera!

Er is bericht vanuit Ardusat over het verbinden van de camera aan je Arduino.

1) The connector. This is a DSUB-9 serial connector that just breaks out the RX/TX lines from the camera. You can look up the pinout online to see which pins are what, but you should only need two pins. The other plug is indeed for a 5V power supply.

Onderstaand plaatje laat de functies van de verschillende pinnen van de connector zien:

 

2) The logic level is 5V, which means that you can connect the camera to an Arduino or other 5V microcontroller directly, but to connect to an old school computer serial port you would need to change the logic levels (e.g. with this https://www.sparkfun.com/products/11189).

The easiest way however to connect to a computer is to get this kind of thing: https://www.sparkfun.com/products/9716. This way you can change the 5V logic level signals directly to USB signals. You can then refer to the protocol document to get data from the camera.

3) The LEDs: one of them is a power LED which will be lit continuously if you supply 5V, the other LED is an activity LED.

Succes en have fun!

 

Er is een lanceerdatum! 

The ArduSat will be aboard the H-II transfer vehicle (KOUNOTORI4) which launches from Japan via H-IIB Launch Vehicle No. 4. After reaching low earth orbit, the satellite has to be launched from the International Space Station. Once launched into its own orbit, it will take about 2 weeks to stabilize the ArduSat. Our best estimate is that the first experiments will begin in September / early October.

Daarnaast is ook de resolutie van de camera omhoog gegaan van 640×400 pixels naar 1024×800 pixels. Dat betekend dus scherpere foto’s en als alles goed gaat kunnen we ook nog meer foto’s terug streamen naar de aarde, doordat er twee satellieten gelanceerd worden.
