Piet Bos

Going through some storage boxes, I noticed I’ve got two items of Piet Bos.

Who was Piet Bos? (link to photo)

In 1938 Piet Bos founded the Natural History Museum in Holten. Bos had a nationally renowned taxidermy company in Holten. In the era of emerging tourism, Mr Bos had a good sense of how he could captivate visitors. He had a unique idea at the time, namely to exhibit stuffed animals in their “own” environment through dioramas (viewing boxes). Not only the dioramas, but also display cases with prepared birds and mammals still appeal to the imagination. Over the years, the collection has grown into one of the most extensive in Europe. Son Kees Bos has given the museum a contemporary character as a painter and sculptor. The name of the museum has been changed to Natuurdiorama Holterberg. Visitors to the Sallandse Heuvelrug can learn about the history and flora and fauna of the area in the museum. The nature museum also shows animals that occur in other parts of Europe. More than 1,000 animals and birds can be viewed in eleven life-size dioramas, accompanied by accompanying sounds.

Multipurpose RGB sensor (ESPHome)

A few years ago, I made a little light metering sensor using a light resistor and a NodeMCU (using analog read).
This would measure if a Led was turned on from my Alarm system. (I had no other way to read this state.
(I also had it connected to our washing machine for a while, to read the state.)

Now I wanted to read the state of the TV set-top box.
This Arcadyan hmb2260 has a green/led state LED, so measuring light is not enough.
(I can only toggle the device from Home Assistant, so there is no way to know the current state!)
Toggling on/off and portscanning the device gave me not another way to get the state (no extra open ports/web state pages) than using an RGB Sensor.

Flashing this with ESP Home and integrating it in HA was a breeze.

I wanted to turn the Illuminance LED also off, because the Set-top box already emits light.

Now I’m going to 3D print a holder which can be used to press the button manually when needed.

The yellow part needs to be 3D printed.

Other ideas:

Measure the dishwasher machine LED.

Tuner hack and an oldskool discman story

Using the Korg CA-20

My old trusty Tuner that is really really old.

On the side you see the bagpipe tuning.
In the past, I replaced one of the LEDs. But now it didn’t turn on any more.

So I took it apart, and what did I miss when replacing the LED?
This tuner has more functionality hidden.

This is more often the case with devices, because it keeps the costs down. Make one print and use in many.
(See the diskman story below)

A working tuner!

When looking at the cover plate, you see only 4 buttons. But there are six!
Then I noticed some solder pads with the lettering Buzz.
So button 5 and 6 are for a metronome!
You see the little piezo buzzer I got from my component’s drawer.

A similar hack was the Diskman player in the 90s.

It was something like the model below. But with black buttons.

There was only play/pause stop and skip whole track or back whole track.

When opening, I figured out which chips were doing what.
Saw that some signals were not connected to the control panel.
These were : Fast forward, and reverse. And skip 30 seconds.

So I glued some buttons on the side and presto.

A few years later, I took it apart and connected a DB-9 connector to it.

Now I could control the playing using my Amiga!

Some drawings I found

Will post chip info, and more when found.

Stop doing this in posts!

See what I did?
