Thanks for the quick replies. I have a few things to try now. For info I'm running a fresh install of Jessie on a B+ And, when launching the python script it with sudo python script.py it cant import serial. I tried with python3 and it gets as far as the error above, and it then i got stuck. **On ed...

Hi forum folk. I have hooked up a microstack GPS receiver to my B+, and can see the NMEA data using cat /dev/ttyAMA0, so the connections are OK . I found the parsing example below and the next step was to adapt it to my means, but it does not run. import serial import pynmea2 def parseGPS(str): if s...

Well done!

Johnny5C

Ditto Dave. I'm really looking forward to the next two days!

Johnny5C

I'm really looking forward to seeing your entry zeta!

Johnny5C

I had this problem. The sunny connector had popped out!

Johnny5C

Bump - for you know who you are.

Johnny5C

As Dougie said, check the sunny connector on the camera itself. It's prone to not being seated properly.

Simple check too.

Caught me out many times.

I did a -10 to +40 run in our test lab yesterday. Astro Pi returned a nice linear response on both of the temperature sensors. Granted, there was a delta between the sensors themselves, and the thermocouple probe, but nothing major. I will remove the RTC board and re-run it tomorrow, to see what eff...

Johnny5C

Rotation? If it can be proven, through analysis perhaps, that the RTC board gives sufficient air gap then the OP's experiment will be valid. My astro pi is one of the few with the RTC board in between the Pi and The HAT. It's the exact same configuration as the flight unit, and has shown that the se...

I posted some code recently to log temperature, humidity and pressure. It yielded good results for me. I left my Astro Pi outside overnight and saw a 15 ish degree swing in the temperature reading using ap.get_temperature() https://pbs.twimg.com/media/CFM80d6WYAA41LZ.jpg How come some people are not...

Johnny5C

Good work. I like this!

Johnny5C

Try this.

Code: Select all

wget https://www.raspberrypi.org/files/astro-pi/kinstall.tar.gz
sudo tar -C / -xvpf kinstall.tar.gz
sudo reboot

Some people have asked for the code I have been using to take-time-lapse videos. Time-lapse photography could be an exciting use for an Astro Pi when on the ISS, looking out of the Cupola? My simple code: import time import picamera from astro_pi import AstroPi ap = AstroPi() with picamera.PiCamera(...

Johnny5C

This is heavy stuff guys.

Does anyone know what x, y and z are in relation to the HAT?

I'm writing a script to use the raw accelerometer values, but my astro pi is doing some data logging, so I cant check...

Johnny5C

This code will read figures of temperature, humidity and pressure and write them to a .csv file. There are a few things you can easily change like maxcount, to adjust the length of time for the experiment, and the sleep time to adjust the time between samples in seconds. It also displays the count n...

1027.34 Millibars this morning in sunny Gosport. Could use this to make a neat little graphical barometer..

Johnny5C

Thanks Dave! Going to try this with the kids later!

Johnny5C

Yeah, just tinkering with yaw, I can see that is plays catchup after you stop moving.

But, pitch and roll take big jumps to the new position.

Johnny5C

I have run your code on my pi, and it look OK on first glance. Watching your video were you only changing the yaw to test it?

Johnny5C

Really good to see some Astro Pi user comments!

The project is getting its legs!

Johnny5C

Got a camera connected to your Astro Pi? This little script will count down from 5 on the LED display and then take an image with the camera. import time import picamera from astro_pi import AstroPi ap = AstroPi() ap.clear() for i in reversed(range(1,6)): ap.show_letter(str(i), text_colour=[128, 0, ...

Johnny5C

Thanks Dave. Worked like a charm.

Had to do the full version, but it's not difficult if you follow the well written steps!

Cheers

I'm lucky enough to have some hardware, because I'm part of the Astro Pi team. I'm putting these example here to record my tinkering, and when hardware gets into the hands of people, schools or other, they can get going quickly. These two just scratch the surface of the capability of the Astro Pi HA...

Johnny5C

The code below will display the IP address of network port eth0 on the LED matrix. I find this useful, as I work my Astro Pi headless over SSH, and often move between networks. (It's another example of how to display variables on the LED matrix) It's also useful to have it run on boot, so.......... ...
