Merlin Garage Remote Housing

I was tasked with fabricating a replacement housing for Merlin M842 remote control for a garage door. Given that the device is most commonly carried on a key chain or thrashed around in a car glovebox, the housing ends up taking a beating with age and a replacement can cost as much as $60 to $90. My goal was to create a competent replacement that would:

  • be user serviceable (accessible battery compartment)
  • have the led indicator visible
  • have a slimmer profile than the original
  • be easy to manufacture using a hobby grade FDM 3D printer
  • and of course I didn’t want to spend too much time working on it

ASUS USB Ethernet repair



My laptop doesn’t have an ethernet port. I either use wifi, or this Asus USB Ethernet adapter. The device identifies itself as a “ASIX AX88772B USB2.0 to Fast Ethernet Adapter”. The other day it stopped working, though if jiggled around, would come on intermittently. If twisting the wire a bit helps the device re-connect, there’s a wire connection problem somewhere, so I decided to fix.

Knife Handle


I picked up an early 1900’s English butter knife from an op shop, which had a bone handle that was completely burnt (I forgot to take a photo of it) and refurbished it with a new handle as a small DIY project.

Recycled Timber Shelf


Few weeks ago, I moved out of home into the Frogshark HQ, the house our team lives and works at, developing video games. Part of healthy living for me is making the place that is “home” a comfortable space and a desired place to be in. I don’t own any furniture except for my bed, so lack of surfaces for storage and ad-hoc items makes the space lack in accessibility. In the spirit of making, I set out to make my first piece of furniture, a simple shelf behind my bed’s headboard.

Motorbike Helmet Sound


In this post I show how I built headphones into my motorbike helmet.

Since I started riding a motorbike, I gradually took on challenges associated with it, such as riding on the motorway, filtering, and lately – riding with music (sometimes). While it can be considered less safe, it presents a different set of challenges and offers a different experience. Your visual acuity elevates, as you compensate the lack of sound cues from the environment, watching out for more dangers and preempt other road users’ actions.

Listening to music while riding puts the experience many levels up. The tactility of the road, the smell, the wind, are now part of the music experience. Pick the right track, and the ride becomes even more visceral while you massage your cerebellum with heightened senses.

Electric Bicycle Conversion

Once upon a time I took it upon myself to create an electric bicycle. At the time I was still doing an daily commute to work 16km both ways, and thought it would be a good alternative to a car. The point was also to learn about bicycle mechanics through practice and have some fun with tools.

Fixing Canon 7D Display Assembly


During my trip to Australia last November, my 7D got damaged in the baggage, where something has pushed against the rear LCD hard enough to dip it into the camera body, creating an opening, where a lot of beach sand and dirt started accumulating. Since my camera is out of warranty, and official Canon repair would cost as much as a new 7D, I take matter into my own hands, besides, I’ve already opened my 7D to fix a battery error already.

Fixing Canon 7D “Cannot communicate with battery” issue


A few months ago, my 7D started throwing up this error, which would refuse to read the battery (even though fully charged) and would actually discharge it rapidly if left inside the camera for a few hours. Searching online for the issue revealed that it’s a common problem for many users, and actually a manufacturing defect in every 7D (MKI), though doesn’t reveal itself to everybody. There is a solution, which I found thanks to the author of this video, which details exactly what the issue is and how to fix it in less than 10 minutes.
My documentation basically follows the exact steps in the video, so hopefully this will help someone as well if you want to know what’s up at a glance.

Swordy PAX AUS Badges


I made a post on Swordy devlog about the wooden badges I’ve made as part of our PAX AUS exhibit & promotion effort. Click on the image for more photos, detailed description of the manufacturing process, along with some post-mortem reflection.

Gopro stabilizer


At some point a couple of years ago, I was into video and wanted a way to shoot smooth footage while walking / skating / going up stairs and what not. To do that, I constructed a stabilizer, following a standard Glidecam design. It involves a 3 axis pivot, and a stem with camera mount at the top and balanced weights at both ends.

I built mine around an M8 screw rod, with skate bearings and PVC pipes held together by nylon locking nuts. It works really well, even not properly balanced. The video below is casual walking (not trying to be smooth).
