Making a frame in a aluminum case, using rivets and nut rivets.
The nut rivet tool (suggestion by Duncan) is a superb addition in my tool shed!
There is place for 4 modules in this “test” case. I need to move the holes for the rivet-nuts, because the modules should go in every position. (Also 4 rounded corners)
Drag and drop image for displaying on a kodi instance
Button to start slideshow of a directory
Open image in browser with obfuscated image url (not shown in movie)
Stop image playing
Json RPC used:
# Playing a single file
curl -H "content-type:application/json" -i -X POST -d '{"jsonrpc":"2.0","id":1,"method":"Player.Open","params":{"item":{"file":"'.$dir2.'"}}}' http://KODI-IP:8080/jsonrpc &';
# Playing a directory
curl -H "content-type:application/json" -i -X POST -d '{"jsonrpc":"2.0","id":1,"method":"Player.Open","params":{"item":{"directory":"/path/'.$dir.'"}}}' http://KODI-IP:8080/jsonrpc &';
# Stop playing (i'm stopping player 1 and 2) You can query which player is active, this works also
curl -H "content-type:application/json" -i -X POST -d '{"jsonrpc": "2.0", "method": "Player.Stop", "params": { "playerid": 1 }, "id": 1}' http://10.1.0.73:8080/jsonrpc';
Kodi enable http control and disable authentication (if you want to use authentication, change the curl commands accordingly)
Below the multiple PHP files, i’ve removed a lot of code specific for my manager.
By the way, I love this trick:
header("HTTP/1.1 204 NO CONTENT");
I’ve you put this in the top of your php script which is linked from the first page, you won’t open this link in your browser, but it gets executed nevertheless!

Below a example of what your can do with the code above
I’ve got an old Speaker Phat, and a Raspberry Zero
An audio add-on board for Raspberry ( same size as the Zero )
Connections
My initial idea was to have the “High Voltage Sid Collection” (Downloaded the 55000 pack) On a mini device, battery operated and with a little keypad.
On the keypad i can select the Sidtune to play, or pressing A and a number the Sids from a certain artist.
The display gives you information about the tune being played. ( The display has an I2C hat to convert 8bits to I2C )
See pinout phat above. I’ve got three choices for I2C connection (green/blue to the Phat)
Direct connect and use different addresses
Use a I2C hub and different addresses
Define a secondary I2C on the raspberry
So I made the first test setup …
Underrun occurred .. So back to the drawingboard. I probably need a better Audio Hat. First to try .. Zero fast enough for sidplay2? Maybe audio over hdmi works??
I’ve replaced strings before so that’s no problem. Starting all over again.
Our Folk Band Harp player wants to due some duets. So lets get playin’
http://pinnerstringquartet.com/
UPDATE: 20230119 Replaced the 4 strings yesterday, not fully tuned yet. Gave the string some time to rest. Looking at the harp this morning. G4 was broken .. d*mn
UPDATE: 20230126 Replaced also the G4, all done. Tuning this kind of Harp. (Salvi Lever harp) You have to put all levers down, and tune them from lowest note to highest. The A B and E strings have to be tuned flat! So by using the levers you can play in all kinds of different keys.
Only cards worth mentioning. I will add more information to this page
Graphics:
Hercules ???? – Did a lot of machinecode on this one. (Which?) CGA/EGA Card ??? – Machinecode hacking VGA .. first card also machine code hacking Matrox Some cards i knew a lot about, i did some manipulations using assembly that were very interesting, but only worked on that specific brand.
The Catweasel is a family of enhanced floppy-disk controllers from German company Individual Computers. These controllers are designed to allow more recent computers, such as PCs, to access a wide variety of older or non-native disk formats using standard floppy drives.
You could connect joysticks and there is a socket for a SID chip on the card.
