Pretty damn crude, but at least I know that the servo can lift that motor, I still need to hook it all up so it is under control of one circuitry (right now motor and servo are separate) so I can make it mimic the actions of one of the servos in my software simulation.
I'm still figuring out this whole electricity thing, I gotta make sure my circuit can actually power all the servos and motors at the same time.
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.

This is the Criterion Turntable and Copperhead Tone Arm, by Continuum Audio Labs. Their flagship model (not shown here) costs $99,000. Needle sold separately.
A local historian has brought to life over 300 years of education in Redcar after writing a book about the combined history of three of its most famous institutions – Redcar & Cleveland College, Cleveland Technical College and Sir William Turner’s School.
After spending 18 months researching, interviewing, pouring through a huge variety of sources ranging from 18th Century receipts, Victorian registers and 20th Century photos, historian Peter Chester has now published his findings with some intriuging and fascinating insights, from a school rat catcher bill in the early 1800s to the latest state-of-the-art robotic technology now being used by students.
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.
This is a batteryless shunting voltage regulator for a small solar panel. I made this one in order to use my testpanel for charging mobile devices. For more info and the schematic, check jiskar.nl
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.
Old radio made of bakelite. A Philco Transitone from 1948.
Lava lamp still works. Radio would take some repair, but I bet it could work too.
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....

Random camera PCB I've been thinking about recently... I got a lot of these cameras broken from ebay a while back - Have been planning to reuse the sensors (they're rather nice, ~8mp-ish I think), but need to do some detective / reverse engineering work. Not something I have time for in the very near future.
