I grew up in the UK in the 70's and 80's and during this time the IRA were detonating bombs in Northern Ireland on a regular basis, funded by collections taken in places like Boston where there is a large Irish community. Yes, it's sad that people died in Boston, but just because this particular pair of bombs were detonated in the USA it doesn't make it an international event.


Comment Similar Thinking (Score 1) 272 272

I am going through a similar exercise right now, all of my music CDs have been ripped to flac format and I'm 3/4 of the way through my DVD collection. In my case I have a server in the basement running Linux Mint fitted with two 3TB hard drives. Linux Mint is the secret as all of the audio and visual codecs are pre-loaded and so far I haven't found a single file that I can't play.


Comment Bad Reporting (Score 3, Informative) 51 51

The quality of reporting in this article really sucks. The printed circuit boards on top of the tins are not 'telegraph keys', they're the transmitters and the white box is the iPhone interface. Quite where the 'sodium clouds' come in I have no idea because in thirty years of ham radio operation I've never seen one, heard of one or used one to make a contact with a fellow ham.


Comment Some Suggestions (Score 2) 208 208

1) Lots of natural light, ideally a corner room with lots of windows. You'll also need at least one of those magnifying lamps.

2) Deep benches, at least forty inches, this is because your test equipment will take up at least a foot of space at the rear.

3) Lots and lots of mains sockets, you'll never have enough. Wire the power through a residual current circuit breaker and a big red emergency stop switch. Make sure your family and other people around know where that emergency switch is.

4) Four channel scope, signal generator, lab power supply (0-40V 5A) with a couple of channels, a second fixed power supply with 12V, 5V and 3.3V outputs and a bench multimeter. DON'T buy cheap, it's better to get a good second hand unit than a piece of cheap Far-East test gear. I like Hameg but I know that opinions will differ here.

5) Anti-static mat and wrist strap.

6) Lots and lots of storage for parts, as with mains sockets you'll never have enough storage.

7) Decent tools, as with the test equipment don't buy cheap. I'm still using some tools that I bought twenty years ago.

8) A set of drawers underneath your workbench for storing your tools. The plastic inserts that go inside kitchen drawers will help keep things in order.

9) A burglar alarm and a lock on your workshop door. All this lot is expensive and you don't want it to vanish and reappear on Ebay.

10) Air conditioning and/or heating depending on your location. Equipment calibration will drift in temperature extremes and the standard of your work will suffer.

For those of us on the other side of the pond there is a reasonably good computer history museum at Bletchley Park. The computer section at the Science Museum in London is also well worth a visit providing you remember that the Pilot Ace is on the ground floor.



Submission + - Where Are The Long Duration Voice Recorder Chips?->

Ganty writes: I'm trying to put together a project that can record up to ten short audio segments in reasonable quality, say an 8 KHz sampling rate. There are lots of digital voice recorders out there made by Olympus, Sony and others that can record for up to a hundred hours but when I look at individual chips to do this the selection is more limited. Futurlec for example sell chips with a maximum 16 minute recording time.
So, where are the long duration voice recorder chips and who makes them?
