So, we're trying to cut this square can with the recommended canopener. How in the world did you do this with this can opener?!?!?!?!?!

We did, finally figuring out we purchased the wrong Oxo can opener! We finally did beat the can into submission and are moving on today. Thanks!!

Hello all - we were inspired by the work here to build a telescope for our own RET program in Hawaii. I then refined the design a bit through a graduate seminar and have added more documentation and software on the later stages to go from raw data to a rotation curve. Hopefully this is helpful to others on the forum https://github.com/interstellarmedium/HI_telescope

GlenLangston commented 2 years ago

Hi You have made great progress!

Congratulations!

Cheers

Hi Jonathan,

Glad to see you’ve found the HI4PI survey.

We’ve been working with Benjamin Winkel, at Max Planck, who provided a lower resolution, all sky image of hydrogen.

You might enjoy looking at the sky, using the jupyter notebook at this site:

https://github.com/glangsto/hi4pi

The HI4PI images are beautiful.

Best regards

Hi Glen,

Thanks for pointing this out - very useful indeed!

GlenLangston commented 2 years ago

Hi

I’ve been working to get all our horn observations accessible via the very fun/remarkable jupyter notebooks.

John Makous pointed out how easy it is to use the Google Colaboratory site.

If you download the attached jupyter notebook and then upload it to the google web site

collab.research.google.com

Then you can calibrate and view the saved observations and all the other notebooks.

You can also upload your observations and plot them with these tools too.

Good luck!

Arg…

The GitHub site that manages these emails removes attachments.

But the attachment is available as a link also:

https://github.com/glangsto/jupyter/blob/master/MilkyWayPlottingColab.ipynb

This whole script runs in less than a minute.

For those of you not familiar with notebooks,

Click in the first box.

Then simultaneously type “Shift and Return” keys to step through the commands.

Its fun…

Cheers

A lot of my students have Macs, so I have been thinking about trying to set the software up on Raspberry Pi instead, but I have some logistical questions for anyone who has used the Pi. What are you using for a display? Do you have dedicated monitors, or are you remotely connecting from a laptop? And if the telescope is outside, how are you powering the Pi? Is battery life an issue?

Thanks, Evan

PranavSanghavi commented 1 year ago

Hi Evan,

We have used raspberry Pis extensively. Typical we login remotely using ssh into the pi or use a vncviewer. Sometimes we attach to a monitor if available or if the initial network setup went awry.

One can power the raspberry pi using power over ethernet but that may or may not require a separate hardware. @GlenLangston @glangsto has more experience with having telescopes with raspberry pi's out in the field.

GlenLangston commented 1 year ago

Hi Evan,

Hope your exploration of radio astronomy is going well.

As Pranav said, we frequently use Raspberry Pi’s for Radio Astronomy.

The code is all available as a single (large) download from: https://drive.google.com/file/d/1tF6BaEj1Sabq6fJXeNpMsqcb8RStfqJs/view?usp=sharing

This code should be installed on a 16GB (or bigger) SD card using balena-Etcher and then plugged into your Raspberry Pi 4B or 400.

You may need a monitor and keyboard for the initial setup, but after that you can run using VNC, which allows you to use any laptop to see what is going on.

The installation guide and examples are in a PDF at: https://drive.google.com/file/d/1nvr6mUQsmsFC07G4KLD4oQAHfzUOfY-b/view?usp=sharing

Many people have successfully done this.

Good Luck!

Glen

Alternatively you can read the excellent step-by-step instructions for building a radio telescope and install the code by downloading the packages from GitHub.

This has been extensively tested too.

Hi Evan,

The VNC service I’m using is free from RealVNC.

Go to downloads instead of accepting the buy it options.

There are other free options also.

Hi Evan,

I have a mini-network of 4 telescopes watching for fast transient events (< 1 micro second in duration). These telescopes are powered by Power Over Ethernet (POE) routers and splitters. (The key science goal is cosmic ray, and maybe neutrino, detections).

For Raspberry Pi 400, a slightly more powerful POE splitter is needed. The 400 needs 20 Watts, which is not much, but 4 of them require 80 Watts.

1)UCTRONICS USB-C PoE Splitter Gigabit, PoE to USB-C 5V/4A Power Supply for Raspberry Pi 4 and More, 802.3at Power Over Ethernet to USB Type-C Adapter UCTRONICS https://www.amazon.com/gp/product/B07V35DH5F/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1

2) SODOLA 8 Port Gigabit PoE Switch with 2 Gigabit Ethernet Uplink ,8 PoE+ Ports 1000Mbp,120W 48V Built-in Power,802.3af/at Compliant,Fanless Metal,Plug & Play Unmanaged PoE Network Switch https://www.amazon.com/gp/product/B09N98CPK3/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

This allows simply running a single long ethernet cable to each telescope, and no extra power wires.

Good Luck!

One can power the raspberry pi using power over ethernet but that may or may not require a separate hardware. @GlenLangston @glangsto has more experience with having telescopes with raspberry pi's out in the field.

Hi Evan,

I forgot you asked about the mini raspberry pi touch displays. Yes they do work, including the touch display, but I found them too small to be useful for much. Maybe my eyesight is not what it could be, but I much prefer VNCing into the device remotely.

If you send me a separate email, I will send you the info to VNC into a running telescope, if you’d like.

Cheers

glen -dot- i -dot- langston -at- gmail -dot- com

You can see the interface via VNC with IP 162.249.150.125

But you need the login info

Thanks, Glen. Do you happen to know if the custom OS for the raspberry pi with GnuRadio supports touch displays?

Hi Evan,

I have a mini-network of 4 telescopes watching for fast transient events (< 1 micro second in duration). These telescopes are powered by Power Over Ethernet (POE) routers and splitters. (The key science goal is cosmic ray, and maybe neutrino, detections).

For Raspberry Pi 400, a slightly more powerful POE splitter is needed. The 400 needs 20 Watts, which is not much, but 4 of them require 80 Watts.

1)UCTRONICS USB-C PoE Splitter Gigabit, PoE to USB-C 5V/4A Power Supply for Raspberry Pi 4 and More, 802.3at Power Over Ethernet to USB Type-C Adapter UCTRONICS https://www.amazon.com/gp/product/B07V35DH5F/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1

2) SODOLA 8 Port Gigabit PoE Switch with 2 Gigabit Ethernet Uplink ,8 PoE+ Ports 1000Mbp,120W 48V Built-in Power,802.3af/at Compliant,Fanless Metal,Plug & Play Unmanaged PoE Network Switch https://www.amazon.com/gp/product/B09N98CPK3/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

This allows simply running a single long ethernet cable to each telescope, and no extra power wires.

Good Luck!

Glen

When you are out in the field, how do you power the Raspberry Pi? Also, do you have any experience with those small touch screen displays?

Hi Evan,

The VNC service I’m using is free from RealVNC.

Go to downloads instead of accepting the buy it options.

There are other free options also.

Hi Glen,

Thank you for your reply. Does VNC cost money to use? When I go to download the software, I only get the option of a 14-day free trial.

Hi Evan,

Hope your exploration of radio astronomy is going well.

As Pranav said, we frequently use Raspberry Pi’s for Radio Astronomy.

The code is all available as a single (large) download from: https://drive.google.com/file/d/1tF6BaEj1Sabq6fJXeNpMsqcb8RStfqJs/view?usp=sharing

This code should be installed on a 16GB (or bigger) SD card using balena-Etcher and then plugged into your Raspberry Pi 4B or 400.

You may need a monitor and keyboard for the initial setup, but after that you can run using VNC, which allows you to use any laptop to see what is going on.

The installation guide and examples are in a PDF at: https://drive.google.com/file/d/1nvr6mUQsmsFC07G4KLD4oQAHfzUOfY-b/view?usp=sharing

Many people have successfully done this.

Good Luck!

Glen

Alternatively you can read the excellent step-by-step instructions for building a radio telescope and install the code by downloading the packages from GitHub.

This has been extensively tested too.

See: https://wvurail.org/dspira-lessons/forum/

Hi - I'd like to try out the DSPIRA activities. I ran into a problem early in the process, where I'm getting an error on cmake. The error messages are: CMake Error at swig/CMakeLists.txt.37 (include): include could not find the requested file: GrSwig

and then there was Unknown CMake command "GR_SWIG_MAKE"

Is this is a common problem, and is there a known solution? Thanks! -George

GlenLangston commented 1 year ago

Hi George,

Glad to hear you’re interested in Radio Astronomy and are ready to start observations.

It appears that one critical step is necessary if you’ve installed GNUradio 3.10 or later. It took me a few tries to get the sequence correct, as it has been a while since I reinstalled from scratch.

The first number it the command history number, ignore that: 1079 mkdir temp 1080 cd temp 1081 git clone https://www.github.com/WVURAIL/gr-radio_astro 1082 cd gr-radio_astro/ ... 1095 git branch -r -l ... 1101 git checkout gr310 1102 mkdir build ... 1104 cd build 1105 cmake ../ 1106 make -j 3

This just worked fine. Probably the key piece that is missing is the:

git checkout gr310

step, which removes all mention of code needing SWIG. There are a few more steps after this including: sudo make install and sudo ldconfig

Let us know how this works out for you!

Best regards

Glen

PS Change the mkdir step to place the code wherever you want it. I typically use: ~/Research

ie:

mkdir ~/Research cd ~/Research

But this is not required.

Hi George,

That was quick work getting to the next issue!

At least the git checkout step worked.

Now I’m guessing that some “sudo aptget install commands” will fix these problems, starting with first messages first.

Since the process dies at doxygen, try this command and let us know what happens:

sudo apt-get install doxygen

This should yield a question about updating, which you should answer YES to.

Also consider:

sudo apt-get update

can be very helpful, but has the danger of breaking things.

Glen

PS: What computer type are you using? If a Raspberry pi, then you could just download the entire operating system image.

Below are what successful CMAKE messages look like. It might be you need to update doxygen or “dot”

Hello again George,

I read your messages a bit further and found the job actually stopped at accessing “PMT” == Polymorphic Types (I think).

Then some Googling yielded a suggestion to fix this with “pip3”

This command worked on my raspberry pi, to update pmt

pip3 install pmt

yielding these messages: Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple Collecting pmt Downloading https://www.piwheels.org/simple/pmt/pmt-0.0.4-py3-none-any.whl (4.4 kB) Installing collected packages: pmt Successfully installed pmt-0.0.4

Hello again George,

After I ran my suggestion (ie pip3 install pmt) my observing software did not run, so DON’T do the above!

There is some other issue with your environment. Probably re-installing some package will clear the issues. Sorry to not have a clearer answer.

Good Luck

Maybe if you summarize the software you’ve installed on your computer we can make a better guess.

Hi George,

Glad to hear you’re interested in Radio Astronomy and are ready to start observations.

It appears that one critical step is necessary if you’ve installed GNUradio 3.10 or later. It took me a few tries to get the sequence correct, as it has been a while since I reinstalled from scratch.

The first number it the command history number, ignore that: 1079 mkdir temp 1080 cd temp 1081 git clone https://www.github.com/WVURAIL/gr-radio_astro 1082 cd gr-radio_astro/ ... 1095 git branch -r -l ... 1101 git checkout gr310 1102 mkdir build ... 1104 cd build 1105 cmake ../ 1106 make -j 3

This just worked fine. Probably the key piece that is missing is the:

git checkout gr310

step, which removes all mention of code needing SWIG. There are a few more steps after this including: sudo make install and sudo ldconfig

Let us know how this works out for you!

Best regards

Glen

PS Change the mkdir step to place the code wherever you want it. I typically use: ~/Research

ie:

mkdir ~/Research cd ~/Research

But this is not required.

Hi Glen,

Sorry that your observing software stopped running! Hopefully you're able to get that fixed.

I'm using Ubuntu 22.04 on a laptop, but will try to get a raspberry pi and see if that works any better, or I'll try re-installing some other things. I don't have much else on here other than gnuradio and python3 , I don't think. Thanks for looking into it for me. I'll reply if I can get something working.

Hello again George,

After I ran my suggestion (ie pip3 install pmt) my observing software did not run, so DON’T do the above!

There is some other issue with your environment. Probably re-installing some package will clear the issues. Sorry to not have a clearer answer.

Good Luck

Maybe if you summarize the software you’ve installed on your computer we can make a better guess.

Hi George,

I do recommend the Pi 400, as they are easy to work with.

I’m in a meeting in Seattle WA, and my telescope computers are in WV.

With VNC, which is in the download image, you automatically can log into your PIs from anywhere.

See: https://docs.google.com/document/d/1T_IJhRzMmsDWOqOOUYMyr36vEMxKXEbWL_G2tNK9Os8/edit?usp=share_link

This document contains a link to the downloadable operating system

Glen

PS: The pip3 commands are easy to undo. I just typed:

pip3 uninstall pmt

and all was fine again.

Hello everyone!

My professor is concerned that perhaps our aluminized home insulation board is too thick. Her estimate is the material is about 1 inch thick, give or take. Is this acceptable or should we invest in thinner/thicker insulation? Thanks!

GlenLangston commented 7 months ago

Hi

The metal surface insulation we’ve used is about 1/2 inch thick. Thicker is OK, if that’s what you have. The metal coating should be on the inside of the horn.

Good luck,

Glen

Hi,

We use half inch foam board insulation with one side aluminized. It is easy to work with, inexpensive and lighter.

Best,

Hi,

As of today, on page : https://wvurail.org/dspira-lessons/HornOperation_spectrometer_description the hot and cold calibration instructions have the same copy/paste text. As such, the cold calibration is missing.

Thank you for the work put into this. Amazing!

Cheers, Paul
