Here are my notes on how to setup a switch so that toggling it will give you one trim value that you can “turn off” in flight.. In my case, I want to hand launch a fixed wing model with some up-trim that I can bring back to normal with a switch. The manual is not exactly clear on how to do this. One solution is called Flight Modes, or F-Mode on the screen. Power On and make sure you…
My notes on how to setup Spektrum DX-6 with a Blade Theory XL because the downloadable setup file was incorrect for me and resulted in hours of frustration. Writing down what I did in case I need to do it again months from now and will have long forgotten. And maybe it’ll help someone else out there…. First you need to get the setup file from spektrumrc.com or Horizon Hobby. Next you need to create a new model because loading…
I can never find this exact gearing chart online when I need it, so I’ve taken a pic of the one that came with my Slash and uploading it here for posterity. Good for the Rustler, Bandit, and Stampede.
The Gigabyte BIOS is so un-intuitive that I’m documenting my notes in case it helps anyone else. While searching online I did not find any answers on how to adjust the CPU Fan Speed. Maybe it didn’t come up while searching because it’s so easy for everybody else to find that there’s no need to document it. I’m good at detecting ambiguity. It is my special gift. So here’s how. Get in to the BIOS by holding the Del key…
I’ve been having terrible problems with my wifi disconnecting randomly. It seems the problem is with the Intel driver, called iwlwifi. I thought I solved it by turning off the Power Management setting for the driver, but the problem returned after 24 hours. The big headache is that the wifi interface is part of the motherboard. Removing the interface from BIOS was not an available option. I also knew that trying to ignore it by simply inserting a USB dongle doesn’t…
One of the most influential websites in my life was 750words.com. It is a site that encourages you to write every single day, about any thing really. Freewriting. I noticed that it helped me focus the rest of the day on my priorities. Even though there was a lot of junk words, after about 20 minutes I’d almost always have at least one genuine insight about something I wanted to do. So I started writing those down in lists of…
Found a solution to a problem that has been plaguing me for months. My wifi would disconnect randomly, unable to recover and requiring a reboot. The solution was not simple to find. Sharing my notes here in case it helps someone else. The problem seems to be the wireless interface’s Power Management. And the solution was simply to turn it off. I narrowed the problem down by watching the syslog until the moment it happened: tail -f /var/log/syslog In the…
Today I realized Atbash can done as an algorithm, rather than looking up a hard-coded dictionary of an alphabet to its reversed alphabet. You could encrypt using the alphabet’s array index as: -i +25 It’s that simple. Example: Assuming you have a list of an alphabet, index(i) will get the plaintext chacter’s position. Then negate it and add 25, and now you have the index position of the Atbash character. Slick! Complete Code: Output: No more rhymes now, I mean…
I just finished listening to The Da Vinci Code audiobook and am feeling inspired to noodle with some cryptograms in Python. One of the clues in the story involves a word written Atbash. This is a simple substitution cipher where the encrypted characters are mapped to the reverse of the alphabet: A -> Z B -> Y C -> X … Z -> A Now let’s write a Python script to do this It’s been a while since I…
Testing is crucial. These are my notes from things I learned on today’s autonomous boat tests. Do not program GPS coordinates at 5am! This is critical. The boat went out to the middle of the lake and stopped. It took me several moments to realize it did exactly what I asked it to do. I failed to enter in return coordinates. The shoreline is dynamic. Do not trust Google Maps, even in satellite view, when getting GPS values close to…
