I am confident to speak for
others
as well when I thank Bram Moolenaar for accepting my pull
request so quickly.
I am really impressed, that you really did that by yourself. I was not
expecting that, because its unusual to be recognized by rock stars when
participating in their concerts.
However I realized, that what this means to me could potentially be something I
could give to others as well. Not because I am a rock star, but rather because
nobody is. We are all humans and we can change the world for the better. Thanks
for reminding me!
Some time ago my blog software broke and I could not help but did not
feel like fixing it. That was now the situation for almost one year and
until today and it was never supposed to take that long, nor does it
mean that I will quit with anything. I am still here, I still work on my
projects and below you find a picture of my latest project, which I will
eventually release as an open source project.
Apart from looking so crude: This device actually worked! I was able to
re-flash the UEFI BIOS directly on the motherboard and the computer
starts again! More important is though, that after that worked, there is
no reason to NOT further play around with the BIOS anymore. Watch out
for news or try it on your own. An interesting low-level world has
forgotten to lock its gate ;)
The whole story: I faced a serious issue with my computer the other day,
when it wasn't booting any more and stuck on the BIOS logo screen. I
tried DEL and the F* keys, but the system did not respond by any means.
But I further noticed, that -within a certain time frame- the NUM lock
key worked with a remarkable delay before the LED reacted. I removed all
components, even one of the two RAM sticks I have- still the same thing.
Since the board had a dual bios, I tried to re-flesh the first from the
second by holding the on switch for a few seconds. Although that seemed
to work it did not fix the issue. I removed and reinserted the bios
battery and started bridging pins of the BIOS chip in order to erase it
until I managed to get the computer in an even worse state in which it
turned on and again off very quickly without showing anything on the
screen. I managed to destroy my BIOS and that used to be something for
which you have send your board back to its manufacturer or buy a new
one. But I was still not ready to give up on it and after some soldering
and bug fixing I came up with a really crude solution, which I now want
to share with you, because this thing looks so terrible, even though it
worked :D Note: I also tried a direct connection with a more recent
Raspberry Pi 3, but for that additional resistors would be required.
Upcycling of an old and defective ATX power supply by using its case,
because that already has a hole and a huge fan and a carbon filter can
easily be placed inside…
At least one switch is required to turn the fan on and off. That is if
you ever like to enjoy light and silence altogether ;)
Its ridiculous how bad I am in drawing. Because of that I started to
learn Blender some years ago. One of my last
drawings was a scene from a dream I once had. With Blender I was finally
able to catch the mood of that scene in an image:
Again on lighting. This time it is a 4x4x4-LED-cube I had laying around
for several month. Building such a thing takes a bit of patience, but
turned out to be relaxing as playing with lego. Programming it can get
challenging, but the software provided does a good job in simplifying it
by providing graphics primitives.
Mainly I wanted to have one, because they look so great. On the other hand this
is also an interesting project, because the exercise is to control 192 light
emitting diodes (LEDs) with a single microcontroller.
Now that the dark season of the year is coming, I felt the need for a
better lighting concept in my room. The blue light is meant to remind me
on how the blue summer sky looks alike. I liked the blue energy saving
lamps even better than its LED counterparts, because they deliver cooler
light. The construction of the lamp is kept as simple as possible.
An IKEA PRÖJS desk pad
forms the lamps body and acts as diffuser. It is held together with a punched
metal strip and M3 nuts and bolds and 3M double sided tape, all of which I had
lying around.
