My µBITX in its new home

Jack, W8TEE
 

This is my stock µBITX in its new home (Banggood case). I'm still waiting on the bezel and some new knobs. The mic is build from the parts in the kit plus a connector I use with some other gear. Cost was $0.87 for the mic.

I also ordered on December 15th using India Post.  I expect we’ll be waiting a little while yet.

You did a significantly better job cutting the opening for the LCD than I did with my 40 in the same case.  Thankfully a bezel hides my sins.  Care to share your technique?

Looks great Jack! I have the same case, but decided to put my uBITX in a metal case, I just haven't figured which one yet, meanwhile I use it all sprawled out on the bench.

A fine looking job,  that. I'll be housing mine in the same Banggood case and think I'll stick metal foil on all panels for shielding. With the sections electrically bonded it should do as well as a metal case.

I've been looking at that Banggood case as well. On some guitar related projects I have used the copper tape and conductive paint shown here. Yes, the paint is pricey. However, you could most likely use the smaller can for dozens of projects.

Actually, Al Peter, AC8GY, did the cut, but I think even I could do it. He used a hand jig (or fret) saw. Draw the outline of the LCD window on the inside of the panel. Drill holes at each corner, but within the outline of the LCD window. Then draw an X from each corner. Drill a hole where the lines cross in the center of the window to be cut out. Free the jigsaw blade and re-seat the jigsaw blade in the center hole. Cut from the center to each corner. Move the blade to one of the corner holes and SLOWLY saw toward the adjacent corner hole. (If you don't trust yourself, clamp a straightedge on the line you're about to cut.) Repeat for all edges. A little time with a file and you're done. I used a small, flat, metal file as that makes it pretty easy to make a square corner.

Hey thats a very nice job, but i’d love to know how much thermal resistance there is in your PA cooling chain.  If you have an infrared thermometer, measure the power transistor and the heatsink and see how much temperature difference their is if any. (BTW Harbor Freight has those thermometers cheap).

I need to get one of those as I don't have one. When I do, I'll post the answer.

I use MG Chemicals "Total Ground", which is a spray on (or brush on) Carbon Conductive Coating for the inside if non-metallic boxes.

Where is the best deal for a bezel?

My cut came out great for the Bitx40, Don’t think I’ll be that lucky twice in a row.

Ordered same box as well. Thanks for great feedback.
what did you do for the speaker?

My uBITXs should show up any day now! On my BITX40, I
used a cutting wheel in a rotary tool, cutting the opening
slightly undersize, and then used a file to even it up
a bit and make it large enough. It worked well, but I won't
know until the next one if I just got lucky or if it will
be easy every time. I don't have any bezels.

Don't all home brewers have a Dremel tool with an assortment of cutting blades and grinding bits to smooth out the rough edges. I couldn't live without them. I use mine for home repairs, car repairs and everything radio. I first discovered their utility in my medical practice. I had many elderly patients with bunions, callouses and thick toe nails that interfered with foot health and comfort. Many of them couldn't afford to see the podiatrist so I set up a vacuum cleaner that the patient held in place and while we were kibitzing I ground away with my Dremel..... Made some friends and had some fun. When I retired I had four Dremels and many different grinding tools. Had to buy a cutting wheel or two for the radio room. Thought everyone would get a laugh from this. (I started out as a country GP and had to do it all. There were no specialists close.)

I have a bezel and knobs coming, but this is what it looks like so far:

The cutout process varies according to the panel material. For plastic, first I draw and outline of the LCD and then I drill 4 holes at the corners, but inside the lcd cutout you've drawn. I then put a T-square to align with the line drawn along one edge of the cutout. I then put the panel and T-square in a vice and saw along the line, relying on the T-square to prevent me from "coloring outside the lines". After I've made the cut, a few passes with a file and that edge is done. Rotate and repeat. If it's metal, I align with the jaws of the vice with the LCD outline and drill a series of small holes. I then use a hacksaw blade to cut the line and finish with a file. The Dremel would probably work wonders here instead of the file.

Doc,

Looks like you used a 1/2 round file. For such windows a flat file without side teeth is best!
