Tech Flashback: AMR, CNR cards
In the Pentium 3 era, some bright mind came up with the idea that they could make a special slot which could provide network/modem capabilities more cheaply by providing the ability to interface with the onboard components directly rather than … Continue reading

Tech Flashback: PCI Graphics Cards
Here’s another tech flashback (and about time too!). The first graphics cards I knew of were in the ISA 8-bit and 16-bit form factor, then came VLB – the last hurrah for ISA. Then the higher-bandwidth PCI, boasting 32-bits. This … Continue reading

LCD Monitor Service/Factory Menus
I’m not sure many people know, but the chips inside LCD monitors are actually fairly smart. For one thing, they generate the on-screen overlay displays which you set your settings with, and they do scaling of different resolutions to your … Continue reading

NDB Band Spectrogram
Following on my earlier post about LF, MW and AM radio – here’s a picture of what the NDB band (200-520khz) looks like at night (click for full image – super compressed JPG – 2Mb 13107 x 1013px!): Look at … Continue reading
VLF, LF and MW Radio – NDB Hunting, ATIS, DGPS and Broadcast
[Very short videos this time … no lectures!] Low Frequency (LF for short) is the band (30khz-300khz) that sits below HF. This band is also somewhat special, and I enjoy monitoring for stations here as well. Its propagation characteristics vary … Continue reading
Site Update: Unscheduled Downtime
Apologies for the unannounced downtime earlier today. As the traffic to this blog has increased (along with web-spider activity from Google, Bing and Yandex), the Raspberry Pi (and my ADSL2+ connection) is starting to see difficulties in keeping up with … Continue reading
About HF Radio and the Sydney to Hobart Skeds
[Note: This is a video-heavy post – it’s probably most interesting to watch the Sounds of HF video and parts of the actual sked (last video). The other videos are included just in case somebody wants to watch them …] … Continue reading
Pixel Pitch Visual Comparison
Most of the photos on this website have been shot using my Canon SX110IS point and shoot camera out of convenience. One good thing about this camera is a very good macro ability “right out of the box”. As part … Continue reading
Counterfeit Nikon Battery Charger – Part 2
[For those who have not read the first part, here it is.] Thanks to a few words and pictures, and a reasonable seller, the issue of the counterfeit charger in terms of faulty goods and financial compensation was sorted. Thank … Continue reading
Counterfeit Nikon Battery Charger – Part 1
In the world of eBay, you really do have to be careful. I try my best, but when shopping on price – often you will snag a counterfeit here and there. This morning, I was delivered a counterfiet Nikon MH-24 … Continue reading
Tripview Bus Time Offset Visualization
So after the discoveries made in earlier posts, I decided to make a bit of an investigation into the data itself. I chose M50, towards UNSW as the candidate route for investigation. So I scripted wget for a 30-second poll … Continue reading
Update on Tripview Live Bus Data
[Continuing on from my last post about Tripview bus data] So I woke up this morning and what did I find? Something had changed. Requesting data at URL’s encoded with http://realtime.grofsoft.com/tripview/delays?routes=SB_???_u always returned no tuples, even for a known active … Continue reading
Youtube Rewind 2012 Australia – Easter Eggs!
A friend of mine referred me to this video last night: While watching it, on the last frame, I noticed this icon in the top right corner … … it’s an Easter Egg! Buried in the video above, there are … Continue reading
Tripview and Sydney Buses Realtime Data
Once I saw that Tripview had Sydney Buses real-time data – I thought this would be fun to play with! One of my friends, Nonie, was quite interested in how the data was disseminated and collected, and I thought it … Continue reading
Setting off a Flashgun with an Arduino
So it might not be obvious why one might want to do such a thing – but it could come in useful. I have a Yongnuo YN560 “manual” flash (no TTL metering, so one had to set the flash power … Continue reading
Point and Shoot Photosite Areas
Since my last post about DSLR photosite areas – I wondered just how it would compare if we threw point-and-shoots into the mix, and say cameraphones. Using the same methodology, I catalogued Canon’s Point-and-Shoot range. I didn’t bother with Nikon … Continue reading
Digital Photo Frames – why they never really took off …
About five years back, digital photo frames were new on the market and there was much hope that it would be a decent way to show off one’s photo collection. Sadly, they haven’t taken off as predicted, and I would … Continue reading

Photosite sizes on DSLR Sensors
So, as people who have been reading my Facebook posts would know – I recently became a Nikon convert – with a D3200 providing lots of megapixels for cheap. Of course, some of that is marketing gimmick, but when you … Continue reading
No computer case? No worries!
A couple of times, I have had old computer parts turn up at my house, and nothing to build it in. Sure, you can leave it lying over a bench (and I’ve done that countless times), but when bench space … Continue reading
Refurbishing unwanted laptops
Well, just today, a good friend of mine gave me an “unwanted” laptop that had served its time. In fact, it was this one – a Dell Inspiron 640m, based on the initial Centrino Duo platform (Intel T2300E 1.66Ghz dual … Continue reading
Special Event: 12/12/12 12:12:12pm
Well, I guess the internet is blowing up with 12/12/12 12:12:12pm stories. Here’s mine – I was at home, preparing to go to uni – putting on my shoes. Around that time, my mySQL server on my RPi crashed, my … Continue reading
Addendum: LG GGW-H20L DL Performance Oddity
It looks like my scans of the MEI disc using the LG may have incorrectly shown a repeatable error when the disc itself is NOT defective. When I looked at the result, I scratched my head and decided to throw … Continue reading
Adonit Jot Mini
Well, one of my good friends (Irfan) showed me this in person, and I just had to have it. So I dutifully went over to The Stylus Company and bought myself one. What is it you ask? Well, it’s a … Continue reading
Recordable Blu-Ray Disc Longevity – Periodic Survey
A while back, I posted a thread on CDFreaks (now known as myCE) about my Ritek BD-R’s which had completely lost data. That thread received in excess of 20,000 views and drew along a few skeptics – those who had … Continue reading
Tech Flashback: Citizen 3.5″ Floppy Drive
I just managed to find an old Citizen drive that’s a bit borderline, and a head-clean didn’t help, so I thought I’d throw it out – but before I do that, I’ll open its guts for all to see. This … Continue reading

Nexus 7 Browser Comparison and Overclocking

Running Ubuntu on the Nexus 7

RS Components – they just can’t get it right!
Okay, so when I started this blog, I was pretty irate at RS. They took forever with the Pi, and when it came, it was dead and needed to be baked. While that has improved things, I’m not yet convinced … Continue reading
Tech Flashback: Kaypro Keyboard – It’s still alive!

Milleniata M-Disc on non M-Disc burners?
