My LGB LCE with new sound system going off mainline to downtown and back to mainline.

Trying out the 'macro' function on a Sigma 70-300 APO.

Add a couple of bright white LED's (10000 mcd) to swimming goggles and you've got a cheap strobe capable of photic driving.

Can be fed audio output from an MP3 Player or a PC sound card. Most of these devices can generate 4Hz or lower signal at a high enough amplitude to drive this circuit.

I would think almost any opamp could be substituted...TLC272 only chosen because it was the closest handy.

You can create low frequency wavefors easily using Audacity via Generate Menu ==> Tone... select low frequency (ie: 8Hz), amplitude=1. You can append multiple tone generations to get a range of strobing frequencies. If you select the 'Chirp' option you can create a sweep.

Then export the file as MP3 file and play out PC soundcard or load into MP3 player if you want this to be portable.

Audacity found at: audacity.sourceforge.net/

***WARNING*** Strobic flashing may cause epileptic seizures for predisposed individuals....it's rare but you might want someone around when you use this the first few times.

I figured I should just stack 'em all up and see what they looked like.

Counterclockwise:

Top: Borrowed ca. 2000 500 MHz Tektronix TDS3054B (thanks, Mike!) perfectly fine but for one bad probe.

Middle: Blue ca. 1986 125 MHz LeCroy 9400, with one channel kaput (see previous photo). Also boots only half the time. Danged thing has a 68000 in it!

Bottom: Broken ca. 1999 300 MHz Iwatsu 8631. Dead because of a power supply that failed one week after I bought it as-is (grr).

Bottom right: New(ish)Agilent Genuine HP! 33120A 15 MHz arbitrary waveform generator, doing yeoman service here as a 1.234 kHz sinewave generator.

Above it: Old 1976 Fluke 1900A frequency counter. I used an identical one when I worked at Motorola in 1981.

Top right: Blue again, I guess. IBM X40, running a soundcard oscilloscope application, which inexplicably flatlined just before the shutter opened here.

Second stage of my PC build included installation of the following:

Soundcard: CREATIVE Sound Blaster X-Fi Xtreme Gamer

All that is missing is the graphiccard.

I picked up a used FT-817, the first version (no 60 meters). I am running it through its paces today on JT65 and WSPR. These digital modes were developed for very weak signals such as moonbounce and scatter. I have an old Panasonic ToughBook along with the FT-817/LDG Z-817 tuner and a Tigertronics SignaLink interface/soundcard. With my ground-mounted vertical, I was spotted in Bulgaria to the east and southern California to the west. I am near Buffalo, NY

All soundcards removed. Computer started with initial bootscreenshot. Here you select if you want to program rythms or make a tracksheet for your 24-track 2" machine !!

The thermal grease was very easy to apply on the CPU and CPU cooler, making the transference of heat even better.

1994 Creative Labs Sound Blaster VIBRA 16 MCD CT2260 ISA Sound Card

Based on the award-winning Sound Blaster 16 technology, the Sound Blaster 16 Vibra delivers the high quality audio.

Sound Blaster 16 Vibra provides CD-quality stereo sound with low CPU utilization and great wave-table music that is ideal for home, business, and Internet applications.

It looks just the same, but it's different -- in fact, it's a completely new phone.

Sometime yesterday afternoon my 7-month-old iPhone's sound card -- or chip, or whatever it is -- died. I was on my way to an appointment when i called ahead. The phone clearly was connecting, but there was no sound. I made several more calls with the same result, before concuding that I was just filling up an answering machine with silent calls. Tried my home number. Same thing. Tried music in my iPod app. Nada. No sound, period.

It was terrifying. I have come to rely on the phone for so many thing. You might say I'm addicted. I certainly went into sudden withdrawal. As chance had it, I became aware of the problem on the far west side, on Mineral Point Road. I headed for the Apple Store, went in and said, "My baby died!" They got me an appointment at the "Genius Bar," and in no time they had checked the phone, found it unfixable, and swapped out a new phone. An easy switch, and under AppleCare, it didn't cost me a cent.

A took me awhile to restore my apps and data from the backup on my computer -- mainly because my backup settings were sort of eccentric -- but I got everything. As of a month ago, that is. (I need to set it to back up more often.)

I usually don't buy extended warranties. Consumer Reports usually says they're a bad deal. The iPhone seemed different, mainly because I wanted to be able to replace it quickly if need be. Glad I did.

NOTE: If this happens to you, be sure to note Karofsky's comment below -- the Applecare warranty doesn't automatically transfer to new phone. You have to talk to somebody to switch it.

This is the corpus delicti. At least that's what I hope. The TDA2822M is just a dual amplifier. It gets 2V supply voltage from the main PCB and about +-100mV sound signal. If that's OK must still be checked. The datasheet gives a minimum of 2V as supply.

Tavolara is a small island off Sardinia, Italy. The island is a limestone massif 5 kilometres long and 1 kilometre wide, with steep cliffs except at its ends. Its highest point is 565 metres above sea level. Currently, the island is inhabited by only a handful of families, and has a small cemetery and summer restaurant. The water around the island is a popular spot for scuba diving. The nearest sizable town is Olbia, and the small fishing village of Porto San Paolo is directly across a small strait. The islands of Molara and Molarotto are nearby. Most of the population of the island was displaced in 1962 when a NATO radiogoniometric station was constructed on the eastern half of the island. The aerials from the station can be seen from quite a distance, and that entire half of the island is restricted to military personnel. Tavolara is also home of the VLF-transmitter ICV, which works on 20.27 kHz and 20.76 kHz and which is used for transmitting messages to submarines. It can be also received (but not decoded) by PCs with a coil as antenna at the soundcard entrance and a FFT-analysis software. The island and the surrounding waters are part of the Tavolara and Punta Coda Cavallo Marine Preserve created in 1997.

The environmental protections placed on the park has added restrictions to the use of the area for tourism.

Obviously I use the PC primarily for a DAW (Digital Audio Workstation)

These are the stuff I commonly use whenever I record.

I LOVE this one. CIRRUS LOGIC! Shoom!

My favorite train, the LCE with a new Dallee Electronics sound system. Since there is no sound for this train available to my knowledge I got the AEM7/ALP44 Amtrak Electric Locomotive Card. Extras included a 3" speaker and a rechargeable battery kit to keep sound on when the train stops. Total cost $160.15.
