Sydney Monorail - Abandoned Stations

Image
City Centre Station City Centre is located near Town Hall. It's surprising to see how dilapidated it's become inside. I only saw one or two shops open, and they didn't look like they had much business! 



Chinatown Station Chinatown Monorail Station is located in Number One Dixonshopping centre. There's not a lot going on in this shopping centre anymore. I saw a small space up for rent right next to the abandoned station at about $250 per week.





Harbourside Station Harbourside Station is attached to Darling Harbour's Harbourside Shopping Centre. I think Harbourside is still awesome and it's managed to keep it

Just popped the lid on my EWI3020m again as part of a tidy-up and took some pictures. Enjoy!





Sony PVM 1454QM Disassembly

Image
Just popped the cover off my Sony PVM 1454QM RGB video monitor. Have had it for a few years, and it's always worked perfectly well - just took it apart for a second time to check more carefully for any obviously bulgy caps.

It seems that these monitors (or at least their picture tubes) were manufactured in Ichinomiya in Aichi Prefecture, Japan. Apparently mine was manufactured in 1996.

Mine had a few defects when I got it (missing Sony logo, kind of grubby, dumb calibration settings, base has been hacked apart for some reason - perhaps to fit into some rack mount?), but was overall a pretty good deal at $50, free delivery!


So all in all, it's a little dusty - but I really love the no-expense-spared modular design! Not entirely sure what's the deal with the paper phenolic board though (FR4 was obviously available back then...).

Akai EWI 3020m Factory Reset | Glitchy Noise Fix

Image
If you've just got your hands on a pre-owned EWI3020m, perhaps from a junk auction, and you switch it on for the first time to hear either nothing at all or perhaps weird bleeps, bloops and funky Atari 2600 special effects in the best of cases, then your problem is likely a dead non-volatile-memory battery.

Why? When the battery-backed memory loses its power completely, it loses its ability to retain information once system power is switched off. When the power is switched back on, the values of each bit in memory are amplified to restore them to normal logic levels. Having been unpowered for some time, the memory is storing only random noise, so all user data is now corrupted, nonsensical, and out of the typical ranges (hit the MIDI button on the front panel and check out the RX and TX channel settings - nominal values are numbers 1-16, but corrupted values will exceed far beyond that range and even roll over into special characters!).
But why are the preset sounds corrupted too?…

Akai EWI3020m Disassembly & PCB Pictures

Image
The EWI3020m's "non-volatile" memory battery is soldered directly to the main PCB, which means you have to take the whole PCB out in order to desolder and replace it. I took my newly acquired EWI3020m apart a few days ago to replace the hardwired battery with a coin-cell battery holder.
Every one of the boards are single-sided Phenolic Paper PCBs populated solely with through-hole components and even jumper wires. You can see in the pictures that even some of the ICs (the CEM3374 VCO and EPROM for example) are socketed! Certainly makes repairs a happier experience.
Here are a few pictures of the disassembly and the main PCB itself; apologies for not having a suitable scanner!

HSC Industrial Technology (Multimedia) Industry Study Example - ABC

It feels like it was a lifetime ago that I finished my HSC, but I've noticed an overwhelming trend in my website's analytics: most people arriving at my website from Google have been searching for things like "IT Multimedia industry study example". How about that! My industry studies from back then are buried deep in my website, so I wanted to post them here to make them more accessible.

Keep in mind that these are old, but I recall one of them was marked 100%, and the other ... I don't recall. But please just consider it more a kick start to get ideas / etc.

Anyway, here they are; hope they help someone! :
