Interfacing with a human interface card

I found an old beaten-up CD player (a Philips AK601) next to the trash container a while back.
I picked it up, found it not worthy of being taken back into use, so I decided to open it up and maybe gut it for parts. I found a couple of motors inside, but what really drew my interest was the human interface card, or the print which holds the buttons and LCD.

The card is a one-sided PCB, with on the backside (the green side which holds the traces) three ICs, and on the other side an LCD screen (with what seems to be two incandescent lightbulbs as backlight, 8 diodes, 13 buttons, one capacitor, one transistor, a 9-strand ribbon cable that connects to the motherboard and a hell of a lot (25ish) wire links.

The LCD is an interesting one: it has 6 7-segment digits and a few more items, like whole-word PAUSE, SHUFFLE etc, separate digits 1-6 (presumably for a cd changer) and two “cd” icons.

Enhanced picture of the LCD segments. Dirt also enhanced.

My curiosity was triggered by how simple everything looked and I started on a quest to understand this board.

Binders for cables — Bindstripjes voor snoeren

As any tinkerer, I have a lot of cables — power cords, USB cords, network cables and the like. I litterally have 5 drawers full of them. The problem is getting the cords to not coil up.

Zoals iedere knutselaar heb ik een heleboel snoeren — stroomkabels, USB-snoertjes, netwerkkabels etcetera. Ik heb letterlijk 5 laden vol snoeren.

Restoring a template / een sjabloon restaureren

The ship I sailed on a lot, the Ebenhaëzer, is a so-called klipperaak — a ship with the front of a clipper and the rear of an aak.
The front of a clipper — sometimes — has klipper curls [examples], which is a painted floral ornament, symmetrical on both sides

Het schip waar ik veel op gevaren heb, de Ebenhaëzer, is een klipperaak, wat altijd uitgelegd is als “een schip met een klipperkop en een akenkont”.
Op de voorsteven van een klipper zitten — soms — klipperkrullen [voorbeelden], ofwel een geschilderd lofwerk, symmetrisch aan beide kanten.

The Ebenhaëzer has clipper curls. [Kasper] wanted to build a chest and paint it Ebenhaëzer-style, so needed a template.
Fortunately, the ship’s paperwork binder has a template, used when the head of the ship is re-painted.

Ook de Ebenhaëzer heeft klipperkrullen. [Kasper] wilde een kist maken en vervolgens schrilderen in Ebenhaëzer-stijl, en had dus een klipperkrullen-sjabloon nodig. Gelukkig zit er in het motorboek van de Ebenhaëzer een sjabloon, voor als de kop geschilderd moet worden.

GR 412 Sentier des Terrils E1: Eijsden — Blegny — Micheroux

I decided to walk the GR412 – Sentier des Terrils — a walk along the coal mining axis — and thus spoil tip (Terril) axis of Wallonia. The GR runs from Blegny, close to Maastricht, to Bernissart, on the French border.

Ik heb besloten de GR412 – Sentier des Terrils te lopen — een wandeling langs de kolenwinningsas — en dus steenberg-as van Wallonië. De GR loopt van Blegny, bij Maastricht, naar Bernissart, dicht bij de Franse grens.

GR 412: Terrils visited

I am walking the GR 412 – Sentier des Terrils.
There are a lot of terrils (slag heaps) in Belgium, about 740 in Wallonia alone, mostly lying on the Liege ­— Charleroi — Mons — Lille axis. The GR 412 follows this axis.

Below is a list of terrils my walk put me on, or directly next to. There are many more I have seen.

The list will be updated as my walk progresses.

Upgrading, no, Killing my media PC

I have a Lenovo ThinkCentre M73 as media centre, with beamer attached.
It played most movies well, but some stuttered. It turned out this box doesn’t have the oomph to play movies. Adding a graphics card would help that.
Today, I tried to add that graphics card, succeeded, and about 3 minutes afterwards, killed this pc.

Installing WordPress Multisite with different domains

I own a few domains: IIVQ.net (this has always been the host for my e-mail-domain), citrastructurae.net and it’s brother xn--citrastructur-ggb.net (see) and urbanandrural.net. I made a few posts on citrastructuræ, but wanted to keep that page for it’s subject while also writing about the tinkerings I do, mainly to serve as a memory to myself so I know what the hell I did 2 years ago setting up that raspberry pi or kodi system. IIVQ.net pointed to the citrastructurae.net page, but I wanted it to contain it’s own blog.

Because I have chosen the cheapest package at my webhost antagonist.nl, I can’t install multiple wordpress blogs, nor do I really want to. Enter wordpress multisite (I recommend you read that and Before you create a network thoroughly before going on). However, I have found the installation non-trivial.
