Connecting a Fujitsu SS-170A to Asterisk

November 15, 2018 8:56 pm Leave your thoughts

For those looking for it, saving you some time: the default NW-Password (NWパスワード) for the SS-170A is: 999999

The Fujitsu SS-170A, while is a darn good looking IP phone, seems to have been designed for some kind of a satellite or trunk phone system. Other than that, I can’t really explain why, when you pick up the receiver, this happens:

< --- SIP read from UDP::5060 --->

and it starts to do long beeps, meaning there is no phone line to call, and stops responding to any input.

Workaround for Conexant Fusion 878A on modern systems

March 14, 2016 8:22 pm

Usually I used my mom’s laptop with PCMCIA and an AverMedia Hybrid TV+FM Cardbus tuner to digitize all my VHS camera recordings.
However that got annoying quite soon, so I got my VCR back into my rack, added a SCART-6xRCA cable, and found the AverMedia Capture98 PCI card I’ve had lying around because a fake chinese EasyCap was giving bullshit image and colors 🙂

However the 2001-dated drivers obviously refused to run on Windows 8.1 64-bit.
The solution is what you see above — yes, DScaler 4!
It supports working with the Conexant chipset directly without the drivers and produces a nice image. I have also installed an x264 encoder to get smaller files (like, 250 MB per 15 minutes average, and I bet the majority of it is uncompressed sound 🙂 ).

The video below was digitized as a test from my SLV-E720 from some weird tape that definitely could do well as a shopping-mall-vaporwave video clip 🙂

Compare the vivid-colored smooth image to a test of a Fushicai Easycap 007 with it’s almost nonexistent colors and jittering frames, and you’ll see why I didn’t wanna go with modern single-chip solutions at all 🙂

Panasonic NV-M3500 VHS Video Camera and a 5 minute battery hack

Disclaimer: whatever you might do looking at this post, you are doing at your own risk. Batteries are chemistry plus electricity, thus, twice the danger — not only you could get electrocuted, but you could also set yourself on fire or something, if you don’t have the necessary proficiency. All the information here is provided for educational purposes only.

(Yeah, it’s been a lot of posts about batteries here recently 🙂 )

I’ve wanted a VHS camera since a long time ago and recently a chance turned up to get one, a legendary Panasonic M3500.
However, it had no power supply, and the original battery didn’t work too.
When I used some PLS wires to connect to the ⎓ jack at the back, all I got is a No Battery icon and then the camera switched off for no reason.

Re-celling a Walkman Minidisc battery (LIP-12)

Hey guys, long time no posts 😀

Recently I’ve acquired a Sony MZ-R30 Minidisc player.
It’s a kinda fun format, but the fact that I had to use a 2AA case in order to enjoy my music was quite disappointing.

After fiddling around with the dead LIP-12H that came with it, I came to a conclusion that it’s definitely a somehow packaged 18650 cell.

TAPE

July 5, 2015 1:41 am

Recently I’ve stumbled upon the Scotch Brand’s Sound Talk bulletin, specifically the 5th issue, which has an audio fragment from a tape recording depicted on page 2 (shown above).

After some experimentation with audio and image processing software, and approximately correcting the speed by ear, this is the result (18KB total for all three):

320k mp3: 

WAV: 

WAV w/o speed adjust: 

The fragment is too small to recover anything decently, but, as the bulletin states, the letter “A” does take the majority of it for sure 🙂

An idiot’s dream come true (7 years later)

August 28, 2014 9:03 pm

So, from now on, this will be my primary desktop. Let’s see how it goes.

The only downside is 64 Mo of VRAM, which is not quite the biggest video card out there, but I might upgrade it someday.

As usual, thanks to Daniil for helping me get this thing here from Moscow.

This monday, Daniil (danila_95) visited Ufa. Except for walking around the city and other fun stuff, he also brought this not-quite-little goodness that Alex Nak got me here.
The [B] well was not working, however, which was quite disappointing with such a powerful machine.

So it was time to jump right into the schematics of it. After some hours of probing and reading, it seemed that QM61 and QM62 were out of business after some weird occasion. The reel motor was spinning, yet no motion was seen from the capstans and the head mechanics (which are, in fact, driven by the same motor). So I had to go to the local electronics shop and get two 2SD2144’s (I was lucky enough to come on time because these were the last two in stock).
Replacing these was a bit hard since the mechanical assembly is in the way of removing the main board. But, after reassembling was done, I connected it to a 110V AC adapter, put in a tape, hit play… Sure enough they both work fine, in reverse and direct modes!

Time to hook it up into the rig, well A to the amp as a usual recorder, and well B to a USB sound interface (a 24-bit USB Sound Blaster) for instant recording, broadcasting and digitization purposes.
Now gotta think up a better stand for the audio equipment, a way of making this work with AIEdit2, and how to get the pillow that was inside back to Alex 🙂

Well just paid a visit to AmegaPrint :3
If you have any tapes lying around that you don’t need, or maybe even a tape deck, I’d gladly accept it, just throw me an email.
