  • Programming a Simple Visual Approach in the CJ3/CJ4 Pro Line 21

    Programming a Simple Visual Approach in the CJ3/CJ4 Pro Line 21

    Before loading a visual, assume the following basic setup:

    • The destination airport is already in the active flight plan and set as DEST on the FMS.
    • The FMS is the selected lateral nav source on the PFD (FMS1/FMS2 as applicable) and the aircraft is navigating normally in LNAV along the route.

    Step‑by‑step: database visual approach (simplest method)

    1. On the CDU, press DEP/ARR to open the Departures/Arrivals page for your destination.​
    2. If you see departures, press DEP/ARR again until you see ARR for DEST at the top of the page.​​
    3. On the ARRivals page, select ARRIVE for your destination airport if prompted.​
    4. In the list of approaches, scroll down until you see the VISUAL approaches at the end of the list.​​
    5. Line‑select the VISUAL RWxx you want (for example, VISUAL RWY 34).​
    6. On the next page, check the RX (runway extension) distance in NM from the threshold (default is usually 5 NM).​
    7. If you want a different length final, type the new distance in NM in the scratchpad and line‑select it into the RX field.​
    8. Press LEGS and make sure the route flows from your last fix to RXxx, then to the runway, with no discontinuity you don’t want.​​
    9. If there is a DISCONTINUITY, line‑select the next waypoint (for example, RXxx) over the discontinuity to close it.
    10. When the path looks correct, press EXEC to activate the visual approach.​
    11. Verify on the MFD that you see the extended runway centerline from RXxx to the runway.​​

  • Free Custom Rules and Actions for AutomateWoo

    Free Custom Rules and Actions for AutomateWoo

    I’ve crafted some more free plugins designed to function as mini-extensions for AutomateWoo, an automation powerhouse for WooCommerce sites.

    AutomateWoo is basically “If This Then That” (IFTTT), but for WooCommerce. It enables store owners to create powerful workflows to automate emails, rewards, etc., and we often use it as a tool to bulk update WooCommerce Subscriptions.

    The following mini-plugins extend the capabilities of AutomateWoo, adding some functions that we’ve used on actual stores.

    AutomateWoo – Subscription Action Add Discount or Fee

    The Subscription Action Add Discount or Fee plugin allows store owners to automatically apply non-taxable discounts or fees to subscriptions after the subscription has already been created. These are added as a “fee” line item on the subscription (not as a discount on individual products).

    AutomateWoo – Order Rule Recent Failed Orders

    The Order Rule Recent Failed Orders plugin can help you monitor your store for failed orders. It adds three “Shop” rules which check for failed orders over the last 24 hours, 6 hours and 1 hour. You could use this rule to, for example, email you if you have more than X failed orders in 24 hours, indicating a possible problem with your payment processor.

    AutomateWoo – Subscription Action Swap Product

    The Subscription Action Swap Product plugin provides a method for swapping products within a customer’s existing subscription, without triggering any recalculations. It’s a very simple action that essentially just swaps the product IDs of the line items, and doesn’t change any prices, taxes, etc.

    AutomateWoo – Subscription Action Delay Renewal

    The Subscription Action Delay Renewal plugin provides an action which extends out the Next Payment Date (the next renewal) of an existing subscription. For example, you could use this to delay the first renewal by 7 days (a real use case).

    AutomateWoo – Order Action Add Free Product

    The Order Action Add Free Product plugin automates the process of adding a complimentary product to a customer’s order. Due to the way that actions are scheduled with AutomateWoo, this is designed for downstream use – particularly after the order has been completed. This was used by a merchant who wanted to add a specific free SKU to packages in such a way that was invisible to the customer when checking out, but before it made it to the shipping provider.

  • Fight Hedonic Adaptation

    Fight Hedonic Adaptation

    Happiness seekers tend to focus on changing their life circumstances, such as buying a new house, switching jobs, or getting married. However, people have been found to adapt to both positive and negative life changes, such as marriage, job promotion, disability, and widowhood. This process—known as hedonic adaptation—can serve as a formidable barrier to achieving lasting happiness.

  • The Natural

    The Natural

    Is there something that you’ve always felt you were naturally good at? Think about that “talent” and try to remember all of the practice that you actually did to get good at that thing without realizing it.

    Naturally fit? Maybe you grew up in an environment where you loved running around and climbing trees a lot – you were practicing without realizing it.

    Naturally good at cooking? Maybe you’ve spent years putting together meals from your cabinets and learning what goes with what – again, practicing.

    “I’m not naturally good at that” is really just a wrongheaded way of describing something that you haven’t practiced enough. If you find a fun way of practicing something without realizing it, then you will eventually become a “natural” at it.

  • Atreus62 – Office Edition

    Atreus62 – Office Edition

    I recently refurbed an old Atreus62 that I got used, and I’m loving it as my new office board.

    It was originally built with Cherry MX Greens, which were waaaay too heavy and clicky for me, so I desoldered them and ordered and installed some Gateron Silent Browns, which I love. And not only that, but my coworking officemates also love them, because they are actually really silent. They took over four months to get here, due to COVID-related shipping backlog from China, but it was worth it.

    Behold, my home board and my office board:

  • Touchscreen interface for SONOS speaker (for my 3-year-old)

    Touchscreen interface for SONOS speaker (for my 3-year-old)

    My 3-year-old loves her music, but our SONOS speakers require a device (phone, computer, etc) to control them. She always has to rely on us to start her music for her.

    Last week, I had an unprecedented day off; it was glorious time to let my mind create whatever it wanted. And apparently, messing around with an API was what it wanted.

    Here’s the final product:

    Features

    • Touching a thumbnail will play that album or playlist from Spotify on the SONOS speaker in my daughter’s room.
    • We can add a new playable item from our phones by saving something as a favorite in SONOS, and naming that playlist with the first part being my daughter’s name, e.g. “[Name] – Frozen 2”

    Nitty Gritty

    Interface

    The touchscreen is an old Lenovo Yoga 13 I pulled out of the basement. It is pretty beat up and slow, but I gave it new life by loading Ubuntu onto it.

    However, since I’m just loading this on a web page, you could do this on anything that is able to run node.js.

    SONOS http API

    The first step is getting something set up to interface with the SONOS API. If you’re not familiar with SONOS, the speakers in your house set up their own little wifi network, with one of the speakers acting as the master, that you can interface with.

    In this case, I chose to use this API, since I knew I could whip up a webpage quickly to leverage it: https://github.com/jishi/node-sonos-http-api

    This API allows you to control individual SONOS speakers on your network through simple http calls. Nice!

    You first have to install node on your computer, then start the API running. It has to be running continuously for the interface to work.

    Webpage

    This is super hacky – don’t judge 😉 (I did it in one sitting on the couch)

  • Learning to Fly (bedtime story)

    Learning to Fly (bedtime story)

    One spring day, a girl and her best friend were lying in the grass, looking up at the clouds in the sky. “I wish I were a fairy,” said the girl.

    ”Maybe you are a fairy but you just don’t know it yet,” said her best friend.

    ”There’s only one way to find out,” said the girl.

    So she got a tall ladder out of the garage and put it in the middle of the yard. “If I jump off the top and flap my arms really hard, I’ll probably fly away, just like a fairy!”

    “Wait a minute,” said her friend, “what if you fly so fast, you get bugs in your eyes?”

    So the girl climbed down, got her goggles, put them on, and climbed back up to the top of the tall ladder, ready to jump.

    ”Wait a minute,” said her friend, “what if your clothes catch on the trees when you fly by?”

    So the girl climbed down, changed into her swimsuit (it was the tightest thing she had), and climbed back up to the top of the tall ladder, ready to jump.

    ”Wait one more minute,” said her friend, “how will you ever know that you’re flying, if you can’t see yourself?”

    So the girl climbed down one last time, dragged the pool over to bottom of the ladder, filled it with a hose, so she could see her reflection in the water, and climbed back up to the top of the tall ladder.

    She took a deep breath, counted to three, jumped off the ladder, and flapped her arms as hard as she could.

    And for a moment, she thought she could fly, just like a fairy.

    Then, she realized that she’s definitely not a fairy, and she fell down down down and splash, landed in the pool.

    But since her arms were still flapping, she started to swim. She did three laps around the pool, then did a backflip and twirled around twice, grinning.

    ”Oh well, I guess you’re not a fairy,” said her best friend.

    ”That’s OK,” said the girl, “because I’m pretty sure I’m a mermaid!”

  • Reboot Takeaways

    Reboot Takeaways

    This month, I was lucky enough to spend a week in Charlotte taking the 3-day intensive leadership training course that was lead by Reboot. I’m sure there are many recaps and reviews that try to take 3 days worth of jam-packed content and try to distill it into a single post. Instead, I will drop in some takeaways and bite-sized quotes that will give you a flavor of what it was like from my perspective.

    TL;DR Reboot was valuable. Here are some tidbits and thoughts of my own.


    Share what you’re aware of, and ask about what you’re unaware of.

    We take actions based on beliefs.

    To generate action, first generate belief in the motivation behind that action.


    Don’t disguise advocacy in the form of a question.

    Stress can result in leaders treating people like problems.

    When someone brings something to you, don’t assume that it’s a problem that you need to take action with. If you’re tempted to take action or offer a solution, ask first if that’s what they need.


    How am I complicit in creating the conditions I say I don’t want?

    The number one indicator of a high performing team is psychological safety.

    This has been obvious to see with the Prospress acquisition. Our team went from being in a safe space and clear sense of belonging to a period of lack of clarity around where we belong. Ideally, we are and can continue to work our way back to belonging, and by extension, being a high performing team.


    When tempted to respond reflexively, ask an open question instead.

    The False Attribution problem is a mental model when people think that when something bad happens to me, it’s because of my situation, but when it happens to you, it’s because of your capabilites.

    It’s easier to receive feedback if you have your appreciation bank full.

    Asking good questions is the most underused leadership skill.

    My thoughts: what are your thoughts on that?

    Parts

    Case 3d printed custom by u/crystalhand using 30% wood filament. Based on these files, edited for BOX switches and TRRS connectors, as well as placing the pro micro holders in slightly different location.

    2 Pro Micros
    2 RJ9/TRRS connectors
    76 BOX Burnt Orange switches
    76 Diodes
    XDA Keycaps. Mostly from here.

    Assembly

    Took a few hours of sanding after this pic. I decided I liked the unstained, unpainted look. It’s homemade, and I want it to look that way.

    Making sure the keycaps I sourced from a couple of different places were close enough in color. Name brand vs. chinese aliexpress generics. Good enough for me!

    Wiring

    Wiring diagrams here: https://github.com/abstracthat/dactyl-manuform

    Diodes going into place.

    Regarding the RJ9/TRRS connectors: TRRS connectors have 4 pins, but the diagram only shows 3 wires, which means there will be an extra unused pin. Just pick 3 and use them. If you got normal TRS connectors instead, they would only have 3 pins, but the same concept would apply. The position/orientation of which pins you connect to doesn’t matter, as long as they are wired identically. (thanks u/crystalhand)
    Wiring completed. This is probably 10 hours worth. Yes, I’m slow, but yes, this was my first time handwiring a keyboard and I really didn’t want to frack it up.

    Finished Product

    Key Layout

    Flashing the Firmware

    Start out by downloading QMK toolbox: https://github.com/qmk/qmk_toolbox

    Try loading the default hex as shown by the GUI, connect the left half to USB, with both halves connected together. Short the VCC and a GND port to put it in bootloader mode, and immediately hit ‘flash’ in QMK Toolbox. Then, disconnect the left half and flash the right half the same way, with the same file. Then connect the left half again, and you should be getting letters when you type.

    Now, to create your own hex. Using the latest release of this repo, I followed these directions: https://github.com/qmk/qmk_firmware/tree/master/keyboards/handwired/dactyl_manuform

    (i.e. navigate to QMK firmware folder, and use `make handwired/dactyl_manuform/5×6:default` to generate the hex)

    I had to change this bit of code to get it to work properly: https://github.com/technomancy/atreus/issues/34

    You may or may not need to do the following to get to this point:

    Download Xcode Developer Tools from the MacOS App Store.

    Install Xcode Command Line Tools via the terminal.

    Install avr with `brew install avr-libc` in terminal, and run various commands to make sure homebrew is updated/upgraded, etc. This may be helpful: https://stackoverflow.com/a/41030599

    Checked all the keys with http://keyboardchecker.com/

    If you have any keys that don’t register keypresses, try going through and resoldering your connections for those switches. Soaking connections in solder solved my issues with missing keys.
