+Title: Theatre Acoustic Panels
+Date: 2021-10-21
+Category: Creations
+Summary: Panels for acoustic treatment in my home theatre.
+Short: 3
+
+Acoustic treatment is one of the most overlooked aspects of home audio. There's no point in spending money on premium speakers if the room they are playing in has poor acoustics.
+
+The primary purpose of acoustic panels is to reduce the reverberations caused by sound reflecting off the smooth walls of the theatre. The path of the reflected sound is a longer distance to your ear compared to the sound coming directly from the speaker. This causes the reflected sound to be delayed by the time it reaches your ear. The delayed signal interferes with itself, causing comb filtering which distorts the signal.
+
+Acoustic panels are placed geometrically where the sound from the speakers would reflect off the wall to reach the listener's ears. The insulation inside the panels absorbs energy from the soundwave which reduces its volume and interference.
+
+![[ panel1.jpg | twelve L-shaped corners of the panels stacked together leaning on a table saw in a wood shop]]
+
+I made six frames in the wood shop of my local makerspace, Protospace.  After cutting the 1x4" pine boards to length, I made a jig so I could quickly join them together with screws.
+
+![[ panel2.jpg | a panel with insulation inside on the ground about to be wrapped with black fabric]]
+
+I added 4" batts of Rockwool insulation into each frame after it was assembled.  I then wrapped the frame with black speaker fabric and stabled it in place while trying to pull it taut.
+
+I sat in my theatre while a friend slid a handheld mirror along the wall until I could see the middle of the speaker in its reflection. This told me the centre point of where to mount each panel because the reflected sound would take the same path to my ear.

+Title: Garage Door Opener Hack
+Date: 2021-12-26
+Category: Creations
+Summary: Hacking my garage door opener to work over Wifi.
+Short: 5
+
+In the quest to automate as much of my house as possible, I thought it would be useful to be able to remotely control my garage door from my home automation system. If I suspected that I forgot to close it while leaving, I could check in my security cameras and then close it from anywhere. It's nice having this peace of mind, even if it almost never happens.
+
+Instead of reverse engineering the wireless protocol, cracking the encryption, and sending my own commands, I figured it would be much easier to hack the hardware. I cracked open a spare remote to find that it contained a basic PCB with simple tactile switches.
+
+![[garage1.jpg | the six parts of the spare remote on my desk: metal clip, plastic buttons, battery, PCB, and two halves of the case]]
+
+My plan was to solder an Arduino controlled relay in parallel with the button that toggled the garage door. I would also power the remote from the 3 V pin. I soldered four wires on to the appropriate pins.
+
+![[garage2.jpg | a closeup of the green PCB with two wires soldered to the battery terminals and two to the button pins]]
+
+I drilled a hole in the plastic case and routed the wires through it while reassembling the remote. It's connected to an Adafruit ESP8266 Arduino with a relay module shield.
+
+The Arduino joins my isolated home automation Wifi network and connects over MQTT, a simple messaging protocol, to my automation server. When it receives a command over MQTT it toggles the relay on for a quarter of a second and then off, simulating a button press.
+
+![[garage3.jpg | the completed system: an arduino with a white relay and wires leading to the reassembled garage door remote]]
+
+Update: this system has been flawless for two months now. It's worked every time I've tried to toggle the door and has never opened by mistake.

+Title: Choosing a Linux Flavour
+Date: 2020-10-31
+Category: Writing
+Summary: A recommendation on which flavour of Linux to run.
+Wide: true
+Short: 6
+
+[TOC]
+
+People often ask me which flavour of Linux they should install. In summary, choose Ubuntu if it's your first time. Once you are comfortable, install Debian the next time you need to install Linux.
+
+I run Debian on my computers and servers.
+
+## Linux Distributions
+
+<span class="aside">Interjection: it's technically called GNU/Linux</span>
+
+When people refer to the "flavour of Linux" they are talking about a Linux distribution (distro). It mostly describes what software is distributed in its software repository.
+
+"A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system, a window manager, and a desktop environment." [Wikipedia]
+
+The major Linux distros are practically all the same. If you master one it's easy to pick up the others. The main differences you'll run into are which tools you use to install new software, and the desktop environment, which is what all the windows and buttons look like.
+
+I recommend two Linux distros, Debian and Ubuntu. Ubuntu is based off of Debian, so they are very similar. 
+
+## Pros of Debian
+
+Debian is one of the oldest distros and many other distros are based off it.  You can see a timeline visualization of all its derivatives here:
+
+<https://upload.wikimedia.org/wikipedia/commons/1/1b/Linux_Distribution_Timeline.svg>
+
+This image is what originally convinced me to use Debian. Scroll down until you see it and zoom out so you grasp how many derivatives it has.
+
+Debian is also non-commercial and requires that all software in its main repository is free and open source. This is important because that grants you the right to study, change, and distribute the software and source code to anyone and for any purpose. They also follow a strong social contract you can see here:
+
+<https://www.debian.org/social_contract>
+
+It's also a very stable Linux distro since they freeze all software features on each release. This makes it great for servers because nothing will break when it updates.
+
+The main Raspberry Pi distro is nearly identical to Debian, so you'll also gain familiarity with it.
+
+## Cons of Debian
+
+Since Debian requires all its software to be free and open source, proprietary hardware drivers aren't included in its main repo. This can make installing Debian difficult if your hardware requires proprietary drivers. You'll need to use an installation image found here:
+
+<https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/>
+
+The fact that Debian freezes software features can also mean that your software gets old until the next Debian release. If you want versions that are bleeding edge, you'll need to use Debian Unstable as described here:
+
+<https://wiki.debian.org/DebianUnstable#Installation>
+
+Don't be fooled by the name "unstable". I use it for my personal computers and it runs fine.
+
+## Pros of Ubuntu
+
+Ubuntu is incredibly easy to install. You can also try it out before deciding to install it. The distro pretty much just works on what ever hardware you have.
+
+It's very beginner friendly because it's so popular. Any problem you search for will reveal dozens of threads with people solving the same problem.
+
+## Cons of Ubuntu
+
+Unfortunately Ubuntu is developed by a commercial company, Canonical. The company's interests come first, before the users' and they have a track record of betraying their users' trust and privacy. 
+
+Years ago Ubuntu had a feature enabled by default that would send your desktop searches to Amazon so they could suggest products for you to buy:
+
+<https://www.pcworld.com/article/2840401/ubuntus-unity-8-desktop-removes-the-amazon-search-spyware.html>
+
+Currently whenever you remote login to your Ubuntu machine, it phones home to Canonical and they collect info about your system:
+
+<https://ubuntu.com/legal/motd>
+
+While these reasons are fairly minor, they are quite frowned upon in the Linux community and are reason enough to switch to Debian once you are comfortable with using Linux.

+Category: Creations
+Summary: My first attempt at painting with acrylic.
+Short: 7
+
+The painting is called “Man’s Reach Exceeds His Grasp”. I've always wanted to try painting and thought I had a good idea, so after a couple of drawings I attempted to paint it. I eventually got it framed at Michaels. Many thanks to my friend Laura for the opportunity to do this, I couldn't have done it without her help.
+

+
+## The Meaning
+
+It’s hard to see in the photo, but the moment the water touches his hand it turns into sand and is taken by the slight breeze. The title is a quote from Andrea del Sarto, a poem by Robert Browning.  It is also said by Nikola Tesla’s character in my favourite movie, [The Prestige](https://www.imdb.com/title/tt0482571/).
+
+“I, painting from myself and to myself,  
+Know what I do, am unmoved by men’s blame  
+Or their praise either. Somebody remarks  
+Morello's outline there is wrongly traced,  
+His hue mistaken; what of that? or else,  
+Rightly traced and well ordered; what of that?  
+Speak as they please, what does the mountain care?  
+Ah, but a man’s reach should exceed his grasp,  
+Or what’s a heaven for?”  
+– Robert Browning from *Andrea del Sarto*
+
+## Creation
+
+I started with the background, trying to make it blurry and out of focus, then slowly progressed to the foreground. The hands were drawn in pencil and painted in. It was quite difficult to get the blending and shadows perfect, but I had Laura to tell me when things didn't look right. Below I am trying to figure out what a hand looks like in a mirror.

+Summary: A device that automatically waters plants.
+short: 8
+
+One day I decided watering my one plant was too much work, so I automated it.  It's also great for when I'm on vacation. The plant is a year old now and doesn't look as good as it used to (kinda like you). So this machine is like its life support.
+
+<span class="aside">Update: this plant died long ago</span>
+
+![[waterer1.jpg | the device and pump on a 2L pop bottle with a tube running to a flowerpot]]
+
+## First Attempt
+
+The design was very simple and soldered together on perf board. A microcontroller turns the pump on for 20 seconds, then waits 24 hours and restarts. The pump ran way too fast so it was slowed down to 10% power.
+
+This design suffered from a fatal problem. After running, there was a chance that the tube would stay full of fluid. If the water level in the pop bottle was too high, it could siphon out. I woke up with a flower pot overflowing with water a couple of times.
+
+![[waterer2.jpg | a new version feeding into a different plant]]
+
+## Second Attempt
+
+I liked the idea so much that I made a second iteration. This one used a custom printed circuit board with a lot more features. The pumping duration could be adjusted with a screwdriver. This was useful as the plant (now a [Ming aralia](https://en.wikipedia.org/wiki/Polyscias_fruticosa)) grew.
+
+Another feature was the ability to run the pump backwards. This completely eliminated the siphoning problem from before. After pumping for a set duration, it would run backwards until the tube was cleared of water.

+My close friend Odai saw a simple coffee table design online that was built out of four wooden wine crates. They are quite cheap and available at any hardware store. We each wanted to make one so went and bought eight crates and some plywood to use as a base.
+
+We went to my local makerspace, Protospace, to build them in the wood shop. We thought it would be a quick job only taking a few hours, but it turned out to be a twelve hour job over a couple of days. At least we were in good company!

+
+![[wine2.jpg | the two tables after staining. one face is centred and the contrast between the dark stain and light wood grain shows.]]
+
+The wine crates were glued and then brad-nailed together. Extra wood was added under the thin top strips for support. After the glue dried, the brad nails were painstakingly removed because the ones we used were too long and stuck out.
+
+After being attached to the base, the entire table was sanded and then stained.  We let it dry overnight and returned the following day to add a quick layer of varnish.

-Summary: Panels for acoustic treatment in my home theatre.
-Short: 3
-
-Acoustic treatment is one of the most overlooked aspects of home audio. There's
-no point in spending money on premium speakers if the room they are playing in
-has poor acoustics.
-
-The primary purpose of acoustic panels is to reduce the reverberations caused by
-sound reflecting off the smooth walls of the theatre. The path of the reflected
-sound is a longer distance to your ear compared to the sound coming directly
-from the speaker. This causes the reflected sound to be delayed by the time it
-reaches your ear. The delayed signal interferes with itself, causing comb
-filtering which distorts the signal.
-
-Acoustic panels are placed geometrically where the sound from the speakers would
-reflect off the wall to reach the listener's ears. The insulation inside the
-panels absorbs energy from the soundwave which reduces its volume and
-interference.
-
-![twelve L-shaped corners of the panels stacked together leaning on a table saw in a wood shop]({static}/images/panel/panel1.jpg)

-trying to pull it taut.
-
-I sat in my theatre while a friend slid a handheld mirror along the wall until I
-could see the middle of the speaker in its reflection. This told me the centre
-point of where to mount each panel because the reflected sound would take the

-People often ask me which flavour of Linux they should install. In summary,
-choose Ubuntu if it's your first time. Once you are comfortable, install Debian
-the next time you need to install Linux.
-
-I run Debian on my computers and servers.
-
-## Linux Distributions
-
-When people refer to the "flavour of Linux" they are talking about a Linux
-<span class="aside">Interjection: it's technically called GNU/Linux</span>
-distribution (distro). It mostly describes what software is distributed in its
-software repository.
-
-"A typical Linux distribution comprises a Linux kernel, GNU tools and
-libraries, additional software, documentation, a window system, a window
-manager, and a desktop environment." [Wikipedia]
-
-The major Linux distros are practically all the same. If you master one it's
-easy to pick up the others. The main differences you'll run into are which
-tools you use to install new software, and the desktop environment, which is
-what all the windows and buttons look like.
-
-I recommend two Linux distros, Debian and Ubuntu. Ubuntu is based off of
-Debian, so they are very similar. 
-
-## Pros of Debian
-
-Debian is one of the oldest distros and many other distros are based off it.
-You can see a timeline visualization of all its derivatives here:
-
-<https://upload.wikimedia.org/wikipedia/commons/1/1b/Linux_Distribution_Timeline.svg>
-
-This image is what originally convinced me to use Debian. Scroll down until you
-see it and zoom out so you grasp how many derivatives it has.
-
-Debian is also non-commercial and requires that all software in its main
-repository is free and open source. This is important because that grants you
-the right to study, change, and distribute the software and source code to
-anyone and for any purpose. They also follow a strong social contract you can
-see here:
-
-<https://www.debian.org/social_contract>
-
-It's also a very stable Linux distro since they freeze all software features on
-each release. This makes it great for servers because nothing will break when
-it updates.
-
-The main Raspberry Pi distro is nearly identical to Debian, so you'll also gain
-familiarity with it.
-
-## Cons of Debian
-
-Since Debian requires all its software to be free and open source, proprietary
-hardware drivers aren't included in its main repo. This can make installing
-Debian difficult if your hardware requires proprietary drivers. You'll need to use
-an installation image found here:
-
-<https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/>
-
-The fact that Debian freezes software features can also mean that your software
-gets old until the next Debian release. If you want versions that are bleeding
-edge, you'll need to use Debian Unstable as described here:
-
-<https://wiki.debian.org/DebianUnstable#Installation>
-
-Don't be fooled by the name "unstable". I use it for my personal computers and
-it runs fine.
-
-## Pros of Ubuntu
-
-Ubuntu is incredibly easy to install. You can also try it out before deciding
-to install it. The distro pretty much just works on what ever hardware you
-have.
-
-It's very beginner friendly because it's so popular. Any problem you search for
-will reveal dozens of threads with people solving the same problem.
-
-## Cons of Ubuntu
-
-Unfortunately Ubuntu is developed by a commercial company, Canonical. The
-company's interests come first, before the users' and they have a track record
-of betraying their users' trust and privacy. 
-
-Years ago Ubuntu had a feature enabled by default that would send your desktop
-searches to Amazon so they could suggest products for you to buy:
-
-<https://www.pcworld.com/article/2840401/ubuntus-unity-8-desktop-removes-the-amazon-search-spyware.html>
-
-Currently whenever you remote login to your Ubuntu machine, it phones home to
-Canonical and they collect info about your system:
-
-<https://ubuntu.com/legal/motd>
-
-While these reasons are fairly minor, they are quite frowned upon in the Linux
-community and are reason enough to switch to Debian once you are comfortable
-with using Linux.

-Title: Man's Reach Exceeds His Grasp
-Date: 2012-04-11
-Category: Creations
-Summary: My first attempt at painting with acrylic.
-Short: 7
-
-The painting is called “Man’s Reach Exceeds His Grasp”. I've always wanted to
-try painting and thought I had a good idea, so after a couple of drawings I
-attempted to paint it. I eventually got it framed at Michaels. Many thanks to my
-friend Laura for the opportunity to do this, I couldn't have done it without her

-
-## The Meaning
-
-It’s hard to see in the photo, but the moment the water touches his hand it
-turns into sand and is taken by the slight breeze. The title is a quote from
-Andrea del Sarto, a poem by Robert Browning.  It is also said by Nikola Tesla’s
-character in my favourite movie, [The Prestige](https://www.imdb.com/title/tt0482571/).
-
-“I, painting from myself and to myself,  
-Know what I do, am unmoved by men’s blame  
-Or their praise either. Somebody remarks  
-Morello's outline there is wrongly traced,  
-His hue mistaken; what of that? or else,  
-Rightly traced and well ordered; what of that?  
-Speak as they please, what does the mountain care?  
-Ah, but a man’s reach should exceed his grasp,  
-Or what’s a heaven for?”  
-– Robert Browning from *Andrea del Sarto*
-
-## Creation
-
-I started with the background, trying to make it blurry and out of focus, then
-slowly progressed to the foreground. The hands were drawn in pencil and painted
-in. It was quite difficult to get the blending and shadows perfect, but I had
-Laura to tell me when things didn't look right. Below I am trying to figure out
-what a hand looks like in a mirror.

-Title: Automatic Plant Waterer

-Summary: A device that automatically waters plants.
-short: 8
-
-One day I decided watering my one plant was too much work, so I automated it.
-It's also great for when I'm on vacation. The plant is a year old now and
-doesn't look as good as it used to (kinda like you). So this machine is like its
-life support.

-
-![the device and pump on a 2L pop bottle with a tube running to a flowerpot]({static}/images/plant-waterer/waterer1.jpg)
-
-## First Attempt
-
-The design was very simple and soldered together on perf board. A
-microcontroller turns the pump on for 20 seconds, then waits 24 hours and
-restarts. The pump ran way too fast so it was slowed down to 10% power.
-
-This design suffered from a fatal problem. After running, there was a chance
-that the tube would stay full of fluid. If the water level in the pop bottle was
-too high, it could siphon out. I woke up with a flower pot overflowing with
-water a couple of times.
-
-![a new version feeding into a different plant]({static}/images/plant-waterer/waterer2.jpg)
-
-## Second Attempt
-
-I liked the idea so much that I made a second iteration. This one used a custom
-printed circuit board with a lot more features. The pumping duration could be
-adjusted with a screwdriver. This was useful as the plant (now a
-[Ming aralia](https://en.wikipedia.org/wiki/Polyscias_fruticosa)) grew.
-
-Another feature was the ability to run the pump backwards. This completely
-eliminated the siphoning problem from before. After pumping for a set duration,
-it would run backwards until the tube was cleared of water.

-Title: Wine Crate Coffee Table

-Category: Creations
-Summary: A coffee table made out of wooden wine creates.
-Short: 0
-
-My close friend Odai saw a simple coffee table design online that was built out
-of four wooden wine crates. They are quite cheap and available at any hardware
-store. We each wanted to make one so went and bought eight crates and some
-plywood to use as a base.
-
-We went to my local makerspace, Protospace, to build them in the wood shop. We
-thought it would be a quick job only taking a few hours, but it turned out to be
-a twelve hour job over a couple of days. At least we were in good company!

-![the two tables after staining. one face is centred and the contrast between the dark stain and light wood grain shows.]({static}/images/wine/wine2.jpg)
-
-The wine crates were glued and then brad-nailed together. Extra wood was added
-under the thin top strips for support. After the glue dried, the brad nails were
-painstakingly removed because the ones we used were too long and stuck out.
-
-After being attached to the base, the entire table was sanded and then stained.
-We let it dry overnight and returned the following day to add a quick layer of
-varnish.
