Ahh, Christmas holidays. The perfect time to muck about with electronics and software. I never thought I’d enjoy electronics this much.
Admittedly, I didn’t make a lot of changes the LEDwall prototype, I just finished it up. I soldered the base of an Arduino Nano to a little soldering board, installed the Nano, trimmed some wires and I added proper connectors instead of twisting wires together and applying duct tape.
I got rid of the GUI and networking stuff that would allow me to set the program remotely. Instead, I added a little jumper to be able to switch the program every time the Arduino starts. Then, I wrote some code to turn the whole thing into a `Do not disturb’ / ‘I am available’ sign.
Besides the two shown above, I’ve also made a blinking display of the letters ‘O-K’ and ‘N-O’ in green and red respectively. It’s a bit painful to look at so the first option (green circle and red cross) seems most useful. If the jumper isn’t here (if I’ve lost it 😉 ) it shows a spiffy flashing raindrops thing that is sure to induce an epileptic seizure.
The WordPress plugin I wrote, Category Posts in Custom Menu, supports custom extensions. Recently, I wrote an extension for someone who wanted to show all posts from some category, say “category A” that were ALSO in “category B” AND NOT in “category C”. So, I helped out (coding, yay) figuring it would give me an idea of whether the extension possibilities I created make sense.
If you’re interested, you can now find all the source code at GitHub. This extension was aptly (ahem) named “cpcm-and-and-not-extension”.
In January of this year, I invited a couple of friends for an archery workshop and dinner.
The goal was to hit the balloons taped to the target and at some point I exclaimed I’d paint a picture of the first person to hit a balloon.
I try to make good on my promises 🙂 though I had to ask her for a photo of said painting, because although I swear I took a photo for my own private collection before I gave the painting to her, I can’t find it anywhere.. whoops..
Ahh, placed it in a wrong folder somewhere, here it is:
I just sent out an order to have my very first PCB design ever manufactured! 😀
When I asked for feedback, they said it looked very neat for a first design 😀
Now all I have to do is wait for it and then I can solder on the components and see if it works 🙂
Edit: CRUD! Yep, forgot to model the resistors. Let’s see if I can modify the PCB after it arrives. If not, back to the drawing board.
Painting of a photograph of my friend and her sister when they were kids. Had fun creating it and my friend’s sister was really happy with it when she received it for her birthday 🙂 Congratz!
When I was a child, I was once asked to create a painting for a church. I don’t remember exactly what the event was, but I ended up creating a painting of a huge colorful mosque. After secondary school, I followed an art class and during my studies in Computer Science and Engineering, I also once took up a painting class. Although painting hasn’t been a constant hobby of mine, I do return to it from time to time. In the past year, I did quite a few paintings from photographs, as gifts for friends or friends of friends.
A year or so ago, my partner and I said to eachother “Wouldn’t it be cool to create a LED wall for our living room?”. We then set about to buy an Arduino and some required components for the first prototype. It took a while for us to actually get started, but my phone tells me that on the 7th of June I sent my technogeeky friends a photo over WhatsApp of my breadboard experiment:
