This is the breadboard with the TX converter complete. The coax is connected to the FT-817 acting as an IF rig, and the blue wire is connected to the balanced antenna port on the R-75. On the input side I'm running 100mW from the FT-817 into a ~20dB attenuator. This signal gets fed to a mixer that combines the signal with the 10MHz local oscillator, then outputs a signal at 136KHz. I will be adding a 500KHz low pass section and a power amplifier soon.

My Olympus OM-2sp. I picked this up a couple of years ago, It was never used and is still in LN condition. I love this camera. Great 1.8 lens, fantastic exposure.
I found this in the trash. It is a general electronics camcorder. It was still in the original box with the original manual. I don't have any use for it though.
A blinking LED controlled gate using an photoresistor. Based on a design in Handmade Electronic Music by Nicolas Collins.
the camera can't handle the bright display with a dim room but after a day or so, I turned the display red.
Logitech G430 is a top-notch choice for any gamer. With its comfortable design, high-quality audio, and reliable microphone, it is the perfect accessory for your gaming setup.
I used my computer’s USB plug as the ground connection, as it is a solid ground and it is right next to my work area. It looks like one wire is connected to the 5v line, but it’s not—they are both on the shield. Yup, more ugliness…
As you can see it's not that clever hardware wise, basically just five pots and a mess of wires. The control jack socket is wired to the pot's wiper so that you can adjust the level to suit, whatever you have plugged in - sensors, children etc.
Kodak Professionnal DCS Pro14n full frame DSLR camera (2003). This camera used for the first time a CMOS 24x36 mm sensor adapted to the analog Nikon F80 frame and the electronics were integrated around. Sold in 2003 for 4990 USD.

This Kmart opened Halloween 1994 as a Super Kmart then in 2010 the deli, meat, and bakery sections were removed and became a normal Kmart
Taken out of an old Tektronix 442 oscilloscope I bought to repair for my electronics ventures and spotted a fuse holder in the back, where this was. It's unlike any fuse I've seen before.

The 2007 Alpine demo car is “eXperience”. The name represents the concept of Alpine´s expertise in iPod connectivity and most speedy transmission.
Featuring 6 PDX amplifiers, 2 Type-X subwoofers, 9 Type-X speakers, The PXA-H701 and the iDA-X001 (plus a lot more!), this high-end demo car showcases just how fantastic Alpine´s “Type X” products are.
One of the main highlights is the centre position for the driver, to enjoy the music at it´s best. The “eXperience” shows an elegant and sleekl designed demo car.
It took the Alpine installers 2 ½ months to create such an amazing demo car.
I'm always fascinated by how these things work. Tons of little tiny wires and doohickeys working together to make something happen...in this case, to send a signal from my computer to my monitor.

About to have its identity changed via a firmware swap (yes, the firmware is stored on that 64 MB CF card). A couple of my colleagues were commenting that now that I've got such a spiffy camera, I need something better than the D50 kit lens to put on it. True that a zillion MP really shows off the flaws in your optics. Something for my savings account to weigh the merits of....

The AY-3-8910 is a simple sound synthesis chip that was very widely used in video games back in the Arcade Golden Age of the mid-1980s. One wag on a retrogaming site claimed that this chip was used in a "metric assload" of games, and while that's not a precise count, it is accurate enough. It provided beeps and boings for, among many others: Amidar, Arkanoid, Bagman, Burger Time, Crazy Climber, Elevator Action, Frogger, Gyruss, Pooyan, Popeye, Scramble, Spy Hunter, Tapper, Tron, and Wacko.
Interestingly, this chip has the Microchip Technology Inc. circle-M logo; this device was designed at General Instrument Corp's microelectronics arm, which spun off to form Microchip in 1987. I don't know if Microchip actually manufactured any of these or if this one was rebranded and re-date-coded.
The green dingbat at the top of the shot is a ZIF (zero insertion force) socket of the matching size for this chip, which I plan to use for prototyping circuits for it. Description and motivation for that are given at the end of this picture's blurb.
