Eleanor Plunkett for Harp

History about this tune:

https://simonchadwick.net/2020/12/eleanor-plunkett.html

Arranging this tune for a duet. (Imgard and myself)

This is a work in progress

I’m using Musescore for this typesetting

A Nelly an chuil chraobhaigh
Is a shuil ar dhaith an fheir ghlais
Ag eirghe dhon la,
O! nach breag dham so a radh,
’S gur [tu] do shliocht na bhfear eifeacht
O Ardmacha breige,
Fuair sar-chlu o Ghaodhalaidh
Le trean-neart a lamh.

O Nelly of the back of the wood
With her eye the color of the green grass
Waking with the day,
O what a lie it is of me to say,
And you with your family from a man of import (?)
O lying Ard Macha,
(Nelly? The man? Ard Macha?) Won great fame from relations
With strength of hand

Old and new computer games

Only the ones i’ve played recently or having good memories playing it.
Only noteworthy games

Pyramid Mummy pharaoh thingy ??? One of the first games i remember.
(Besides Pong on a “pong-only” system)

I’ve played a Mummy game in Black/White on a XZ81 or ZX Spectrum, one of the first Computers i had access to. (Richard)
But i can´t find/remember the name.

The Sentinel (1986)

https://classicreload.com/the-sentinel.html

https://en.wikipedia.org/wiki/The_Sentinel_(video_game)

In The Sentinel, the player takes the role of a Synthoid, a telepathic robot who has to take control of a number of surreal, checkered landscapes of hills and valleys, by climbing from the lowest spot, where the hunt begins, to the highest platform, over which the Sentinel looms.

The Synthoid itself cannot move across the level; instead it can look around, accumulate energy by absorbing the objects that are scattered across the landscape, create stacks of boulders, generate inert Synthoid shells and transfer its consciousness from one of these clones to another.

Kings Quest II? (1985)

Played this with my friend Richard on his Atari ST

Few years later, same kind of Game Engine:

Leisure suit larry in the land of the lounge lizards

The Myst series (1993-)

Carmageddon

The player races a vehicle against several other computers controlled competitors in various settings, including city, mine, and industrial areas. The player has a certain amount of time to complete each race, but more time may be gained by collecting bonuses, damaging the competitors’ cars, or by running over pedestrians. Unusually for a racing game, checkpoints do not extend the time limit.

7th Guest

The 7th Guest is an interactive movie puzzle adventure game, produced by Trilobyte and originally released by Virgin Interactive Entertainment in April 1993. It is one of the first computer video games to be released only on CD-ROM. The 7th Guest is a horror story told from the unfolding perspective of the player, as an amnesiac. The game received a great amount of press attention for making live action video clips a core part of its gameplay, for its unprecedented amount of pre-rendered 3D graphics, and for its adult content. In addition, the game was very successful, with over two million copies sold. It, alongside Myst, is widely regarded as a killer app that accelerated the sales of CD-ROM drives.

DOOM and Quake

Many many hours i’ve spend playing doom with Mandy on my first network (1995?)
Quake was my Graphics Card Checker, i never made it to level two!

Amiga

Shadow of the Beast, Super Frog ,The Sentinel, Game of Thrones and Dr Mario
https://www.youtube.com/watch?v=OuGilF0TwYA

And dual player Stunt Car Racer. We played this before there were networks, using a serial cable!

Simulators and more

I used to have Microsoft Flightsim (the old version) , but my main operating system is Linux so i switched to XPlane (Windows, linux and Mac) See other posts about Flightsims

VR games

We bought VR glasses.
Besides viewing movies in 3D, playing with Blender in 3D, Xplane flightsimulator there are some games i sometimes play.

I expect you to die, WWI Warplanes, Green Hell and Mass Exodus Redux. The last one is great fun together with a PC player.

Android games

Tried several games, non stuck.
I enjoyed “SpaceTeam” the most.
Current (dorment on my phone) : Mekorama, BinaryGrid2 (Yes Nerd), Dice me and 2 Player Reactor (those last two, for playing with friends while traveling)

Arcade games

I only knew Galaga, on a table version in Germany (We played there with the Concord Pipe Band)
The other one was
Hyper Olympics by Konami ( Snackbar “Lunch” when attending school LTS Deventer )

PC Games (Recent)

Uboot, Xplane Flightsimulator,Keep talking and nobody explodes
https://store.steampowered.com/app/494840/UBOAT/

Switch Games (Recent)

Limbo, Unravel Two, Death Squared,Machinarium,Degrees of Separation, Guacamelee 2
Mostly Co-op

Sidetrack … pinball

I really like the Terminator pinball game.
There is one in Zwolle at https://computermuseum.nl/
(This one i played when i was a soldier in 1992)
I have some test setups for Virtual Pinballs, but its not the same.

“Recent” old Skool games

Escape case work in progress

UPDATE: 20230214 more work done

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)

Module example https://www.henriaanstoot.nl/2022/12/20/connect-the-wires-puzzle/

TODO:

Alumium squares instead of these wooden temporary pieces.
Making a buildin power connector like this.
Think of something to place in the lid!

UPDATE: Didn’t go for this solution.

Blender rigging

Last week i’ve been learning about rigging in blender.
Before that i’ve learned about bumpmapping .. cool stuff

Bumpmapping

Below is a little shorthand/lab notes/screenshot dump, there are far better tutorials on the interwebs!

First add Rigify Addon

Get a model in T pose, and add armature.
(Not my model, just used for demo purposes)

Kodi push pictures/directory from website

For a new project i’m using parts of my Photo Manager.

UPDATE: Random photo push from directory in one script.

I will post the Minimal code for the following:

  • Caching thumbnail generation
  • 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

Quick previewing negatives using OBS

I’m using a camlink to connect a Nikon camera to my PC, but you could use your webcam also for this trick.

Now i can activate the full screen projector in OBS to preview and sort the negatives on a big screen. (right click on you preview screen)

When connecting a camera to OBS you initially have a “negative” image.

Below trick inverts your image, after that you can use your camera controls or OBS colour correction filter to adjust.

I’m using gimp to invert the LUT png image, but most image editors can invert an image.

A LUTs is a LookUp Table. Color presets/filters for adjusting the image.

Hardcore method .. command line

convert input.png -channel RGB -negate invert.png

Wanted to make a mini Sid Player, and failed

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??

A Harp in the house again. JOY!

First I have to replace 4 strings.

Apparently F4 B4 F3 and D1

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’

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.

Very nice overview of the keys (harp-school.com)
