I completed the 'Build a Power Supply' tutorial seen at https://dronebotworkshop.com/linear-dc-power/
This was my first electronics project and so I recreated all the steps that Bill shows in his two-for-one video, though I improvised where I thought appropriate.
Mostly the changes I made were to use a larger project box so I had more room for error (and I needed it!) and also to add a larger heat sink.
The metal case is fully grounded, every exterior metal screw reaches ground even though the front and back panels are separate from the base, and also the lid.
Feel free to ask questions about it, I will do my best to answer, there were many details along the way.

Nice job. You haven't put anything in your profile so I don't know where you are located. The reason that is important to me at least is knowing if it makes sense to ask you for parts sources. If you are in Australia and I am in Canada then obviously shipping is a killer, but if you are in Canada or USA it might be reasonable. I use google all the time to answer technical questions, but can't seem to find reasonably priced parts so any clues are most welcome.

@zander Thanks. I live in San Diego, California. I am coming from the hobby of astronomy and so electronics seems ever so much more affordable! I didn't do anything special to acquire parts - Mouser, Digikey, Jameco, Amazon. I began with Bill's suggested parts except for the project box and I ordered two of everything. There is a small outfit in Florida that seems to do cheaper parts, mpja.com, but I have never used them.

You're being kind, you improved it! I love your front panel design.This was my first electronics project and so I recreated all the steps that Bill shows in his two-for-one video, though I improvised where I thought appropriate.
If this is your first project, I can't wait to see your second one!

@pawsmode I hear you, I sold my big Newtonian a few years ago, didn't fit into the RV life, then sold my 80mm TeleVue Refractor 2 years ago since using it without a decent tripod was pretty much hopeless. I still have good 70mm binoculars and a balanced binocular tripod plus a spotting scope. I use Amazon.ca, and AliExpress and just made my first buy from DigiKey. Anything coming across the US border can be a problem if the supplier has not pre-paid the correct duty if any. Amazon.com does cross-border fees and they are reasonable. Anything by courier can be horribly expensive, I was pleasantly surprised at the cost of FedEx with DigiKey.

@dronebot-workshop Thanks Bill, yes the front panel took a few iterations before I was happy with it!
