Case Morse Key Converter based on FT232RL USB-C JackPlug
Description
Hi guys, I needed a morse key adaptor for my computer - so I used common parts, but lacked a proper case. I decided to go for: * FT232RL (USB-C) * 3,5mm Jack Plug * Non-additional-screws design (it uses the nut of the Jack Plug) * Small frame for a label (on top) STEPS === * Print both parts and clean (from support) * Solder the wires between board and jack plug (make sure you don't have leftovers at the bottom of the circuit board) * Push the board in to the bottom part (it should click, use a bit pressure at the black plastics of the backside connectors) * Lay in the Jack Plug properly (GND contact upwards, the other contacts will help that it doesn't when screwing on * Slide on the upper part (it should secure the board additionally) * Check that the Jack Plug is still in good position * Screw on the Jack Plug nut (you might need to use a small screwdriver for that - the nut has two little scores) * Test :-) Wiring === I hope I got it right - I just have a straight morse key, not a paddle. I used the wiring description of an ICOM transceiver. So connect... * DSR to (2) at Jack Plug * DTR to (1) at Jack Plug * CTS to (3) at Jack Plug That results in the first pin as (dit), the middle part as (dah), and the large part as ground. PARTS === The FT232RL is with USB-C Connector. These are quite rare in our region, so please check beforhand what you have / is available to you. I purchased mine via ebay. Jack Plug: I got mine via ebay. Diameter is 8mm, total length about 14.5mm - just for comparing that you chose the right one. Label === Well, this was more a trial. I own a standard label writer and printed a small label (25mm x 12mm) I put on top. I add the label as PNG - but most likely you want to create your own. I needed to use strange margins to print it via Linux. Now, have fun!
