Re: Astro Pi Temperature Sensor Reading

I used a tall stacking header https://www.adafruit.com/products/1979 and put it between my Pi and sense hat. I soldered a proto board to it https://www.adafruit.com/products/2310 Now my temps read ambient. I now also have a spot to mount my RTC module and a few other odds and ends with easy access ...

Re: Astro Pi Temperature Sensor Reading

had my sense hat mounted on a Black Hat hacke3r Mini Kit and it worked without issue? Raspberry Pi A+. Raspbian Jessie. If your running Wheezy, the matrix will light up and just stay on until you do some updates and the sense hat support files. EDIT: Are you sure you didn't get the ribbon cable bac...

Re: Astro Pi Temperature Sensor Reading

The heat pipe would keep the sensor temperature much closer to the temperature at the other end of the pipe, minimizing the effect of warm components near the sensor. It's the same principle as the heat pipe you find attached to the CPU in a laptop, except that one is about removing heat produced b...

Sorry experix, but i don't understand the purpose of an heat pipe over the sensor

Re: Astro Pi Temperature Sensor Reading

It's not an option for the ISS use case but for home use you can connect the astropi via a 40-way ribbon cable and a male-male adaptor. I'll add a photo of my setup when I get to the office. OK - picture - IMG_0161.jpg I'm actually using a 40pin stacker header that passes through the astropi socket...

Re: Astro Pi Temperature Sensor Reading

I agree with pashworth that there is a relevant design issue in the sense hat. The temperarute reading is clearly not accurate because of the raspberry cpu heating. And it's not easy to connect the sense hat with a 40 pin cable in order to avoid heating. For example while i was trying to transform t...
