This is a weekend project to keep your filaments safe & dry. It’s very easy to rebuild and adapt to your needs with (hopefully) available spare parts.
After a long term abusive relationship with the 3D printing hobby, where I was brutally murdered several times as described here, it was finally time to find a good partner and settle down. I bought the Original Prusa MK3S. I can finally print dickbutts using plastic. 07 October '20

Why is it that hard to 3D print across years? Why can’t I have consistent printing experience, while not spending a kidney? I don’t get it. Why is the machine constantly failing? I’m a computer guy, I know that human errors are all over the place but how does a machine break on its own so frequently. And don’t get me wrong, it might be a budget Creality Ender 3 but it’s proven to be a good machine and its components are not majestic. 04 October '20

Oh Rust, how much I love you… Love at first third sight, like I had with my English teacher. She was ugly but I was 10 and she was a female that stood near me for an hour and talked to me in a soothing voice. That’s what Rust is, ugly but it’s there for you with a soothing voice.
On the other side we have C++ that the Arduino Framework is written on. 27 May '20

This is a small journey on how I reverse engineered the MagicForce 68 keyboard and tried to add bluetooth functionality to it. It’s a small keyboard (68 keys, 65%) and is USB-only (it’s not the smart model). It has a controller that I can’t flash with a custom firmware, so I had to hook wires on it.
The Hardware The first step in determining what I was against, was to at least partially disassemble the keyboard. 22 April '20

First of all, lets flash Adafruit’s NRF52 bootloader for easier future flashing
My J-Link was “Broken. No longer used” - or so the JLink tools said (AKA bought from e-bay). So I had to go to openocd).
Connect the J-Link (or any SWD capable debugger supported by openocd - even an FT232 breakout will do) to the target - I have a Bluefruit by Adafruit.
pip3 install --user intelhex cd Adafruit_nRF52_Bootloader git clone https://github.
