2 Minute Ride On the Express Rail Link

I had booked a late return flight (9pm out of CGK) thinking I was going to be at the installation site -- about an hour and a half's journey outside of Jakarta -- on the second day of my trip as well. Turns out we finished whatever needed to be done on site on the first day itself, and just needed follow up meetings with the client at their headquarters in town. But then ... things went too smoothly and the meeting was concluded by 10.30AM ! I will surely go mad if I have to wait ten and a...

Carry on Luggage #rant

So I get to the check-in counter, and make the mistake of heaving my backpack off my back. Now I've recently subscribed to the "travel lite" school of air travel and just squeeze everything I need for a 3D2N trip into my backpack, and travel without any check-in luggage. It's liberating to not have to deal with lugging a suitcase all over the place. Check in goes smoothly -- until the check-in staff asks if they can weigh my backpack. It turns out I'm 2kg over the limit which is 7kg. Now fo...

The Case of the Missing Driving Licence

So I happened to be in Petaling Jaya New Town, when I discovered my driving license was not in my wallet. I've been driving illegally since god knows when! A quick search of the area below the car seat and seat pockets turned up nothing (Well it turned up a lot of stuff, but not my driving license). Now the JPJ office (the department of motor vehicles) was just down the road, so after evaluating the risk of continuing on without a license in the hope that it will turn up somewhere versus get...

Getting Free SSL Certificates from letsencrypt.org on OpenWRT using dehydrated SSL

I remember a time when acquiring SSL certificates to enable HTTPS on a web server was a tedious process ... not only did you have to subscribe but you would need to verify your identity by submitting all kinds of paperwork to prove your existence. These days you can get SSL Certificates sign-by browser recognized certificate authorities for FREE. The catch with most of them is that they are only valid for short periods such as 30 or 90 days, and you have to update your certs to a renewed ...

Relocating LUCI to a different port on OpenWRT 15.05.1 Chaos Calmer

I wanted to run a http (port 80) and https (port 443) reverse proxy on my router, and luci running on port 80 got on the way. So I decided to move luci to run on a different port. Here's what I did: Edit /etc/config/uhttpd, and changing the following lines:from:config uhttpd 'main'list listen_http '0.0.0.0:80'list listen_http '[::]:80'toconfig uhttpd 'main'list listen_http '0.0.0.0:81'list listen_http '[::]:81'Reboot. You should now be able to access luci via http://192.168.1.1:81/. You ...

Adding SSL to NGINX on OpenWRT Chaos Calmer 15.05.1

Motivation I wanted to upgrade the apache http server reverse proxy in my OpenWRT router to support https (http over Secured Socket Layer (SSL) -- basically a way to encrypt web traffic to a server). This is so I can secure access to my home-based resources using https, something which is becoming the norm these days. This should be simple enough to do in apache http server, but it turns out the build of apache on my router breaks http when https is enabled. I looked at haproxy, which i...

Removing Pinion Gear From Stepper Motor : .sha VS pinion

Back in September I tested using a 12V 28BYJ48 Stepper Motor to move the throttle levers on my 737 Throttle Quadrant. It worked, but I believed it was at the limits of the motor's torque capabilities. If you look back at the video, you'll notice the motor jumps a bit when crossing the 45 degree point probably due to the sudden shift in weight. My gut instinct told me that I should upgrade the motor now before proceeding with the rest of the design. The motor size is the biggest (literally) h...

MH716 WIII/CGK to WMKK/KUL 3 Oct 2017

I had an afternoon meeting which was scheduled to start at 13:30WIB and go on "Sehingga Selesai" ("until ended"). I didn't want to risk missing an evening flight, so I scheduled my return flight the next morning -- which meant for once I got to leave Jakarta in a fresh, relaxed and stress-free state. I booked a seat on MH716 which departs CGK at 12:15, as the price was quite reasonable, by MH standards. When checking in onlin though, I was surprised to discover the flight was rather full. I ...

British Airways A380 In Kuala Lumpur?

Today (1 October 2017) I spotted a British Airways A380 here in Kuala Lumpur International Airport (KUL/WMKK). Which is interesting because British Airways services the KUL-LHR route using Boeing 787 Dreamliners. So what was a British Airways A380 doing here? Diverted? Lost? I checked the inbound BA34 and outbound BA33 flights to KUL for the day and they were still using a Dreamliner (G-ZBKN). So this A380 was not here taking passengers to or from London. Unfortunately the aircraft was...
