Excellent progress Nick. I keep looking for better ways to mount displays without having to use a bezel, but machining up a bit of black Delrin on the mill is just so easy. I use some very nice Vallorbe files that are extra fine to get a good finish on openings in aluminium and steel, but it's never really smart enough. Even machining apertures on the mill isn't really nice enough, but bezels always seem too heavy and brutal. I'm getting a big new CNC mill soon, so complex shapes will be really easy to make. I wondered about making a wire-EDM CNC so I could make perfect square corners, and even tried making and hardening my own panel punches, but nothing really looks beautiful enough! I rather like the look of E-Ink displays, but they aren't fast enough for frequency displays, or at least the ones I've tried aren't. Homebrew is hard.

Wow! That all sounds very impressive. I'm afraid my metalwork skills are very limited and quite often I'm shoe-horning modules into bread bins so we are not really talking high production standards! I'm really pleased that there are others who ARE good at this though! 73, Nick.

Getting things to fit - loads of stories there. Nice video Nick. I have some of those blue boxes. I think yours are the same, mine came with steel panels. You can do yourself a big favour by replacing them with aluminium. Much easier to work with. Another type of nibbler tool : (Farnel order number) Manufacturer: DURATOOL Manufacturer Part No: TTK-752 Order Code: 2801170 There are others such as the Anvil AV-NIBT which is the same design, more expensive.. These nibblers take a small 4 or 5mm notch every time you squeeze the handle. Best used of Aluminium. You can use these to clean up an edge very nicely. They only need a 6 mm hole to start, and can cut square corners easily. Another tip is to use a cad package to draw out the panel. Mark out all the centres. Print it full size, then lightly glue it to the panel and then just centre punch through to the panel. Saves a lot of measuring (and mistakes) Andy

Nice one Nick! Next time ('cos we all know there will be one) there's a Weller vacuum desoldering station just down the road!

Thanks for sharing your hiccups as well as your triumphs. Although I wouldn't wish failures on you, there is a comfort to know that it happens to the best of us... and to be able to learn from what went wrong.

Thanks for sharing Nick, we are all amateurs and are allowed to have errors in our design, it's the best way to learn ("I think"), you tend not to make the same mistake again; thanks for sharing yours; now off to continue work on my receiver and hopefully keep it error free. 73 Bob

Great work Nick. For next time, perhaps keep the regulators a little further apart, they can get hot. No clue why your Nano regulator died but I'd wonder if the TFT and backlight led tipped the scales.

Thanks Nev. I did try the regulators a bit further apart but unfortunately I ran out of board space. I might be able to squeeze a thin heatsink in-between them if it gets too hot in there! 73, Nick

Quick follow-up Nev - I've gone for the simple low tech solution of bending the regulators apart a little so there is now some air flowing between them! Thanks very much for the heads up. 73, Nick

Thanks Nick, another very helpful and entertaining video. I am building an HF receiver and get lots of good ideas following your exploits. It will use the same 1.8" TFT screen as yours (with the red PCB) so I am tempted to get one of those bezels from the link you provided. Can you give any guidance on how much cutting / filing was required to get it to fit your display? Thanks, Brian G3ZOH

Thanks Brian! I'm pleased your receiver is coming on. I think the bezel just needed a little shaving off one end of the internal baffling to accommodate my screen. You can buy the bezel + a screen that fits from the same source I linked to. I actually did that but the screen they sent me wasn't as good as the cheap one from China. Hence the files came out! 73, Nick
