I grew up with a father that could fix things, build things, tear things down and put them back together, and who was just comfortable around tools in general. For whatever reason, I never picked up that ability. I'm completely inept with most tools beyond the basics. Putting up a shelf is an afternoon task of pure frustration for me. And being a homeowner has not improved that situation at all. Yet if you sit me at a computer, I can make it do wonderful things. Given my tools of choice (development environments, programming languages, etc.), I can really crack open the hood and let loose, commanding the raw processing power of the CPU to do my bidding on massive amounts of data. In fact, I make my living finding new ways to express that power in new and compelling ways, and then showing it off to convince others that my tools of choice are the best tools of choice. Close the hood of that computer however, and all my work disappears. When my dad closed the hood of the van on an engine he rebuilt, he had a vehicle that would get him another 100k miles. This discrepancy has not gone unnoticed. While I've never had the ability of those many tool-bearing manly men, I've always had the desire. As I progress in my career and find that I'm increasingly comfortable (bored?) with more complex computing tasks, the more I want to "get outside the box." Over the past few years I've become increasingly compelled by electronics and robotics, but it wasn't until just this year that I put my foot down and started venturing into new realms - the physical realm. Even given my knowledge and experience, I've only been able to talk to things attached to the computer - that is until now. This morning, with Paige off for an overnight stay at the grandparents, I broke out my ever growing stash of electronics and began hacking. I had taken many baby steps up to this point. I had previously gotten an ultrasonic range finder to report to the computer about the distance between it and the items in front of it, but that was only of limited use as I was still tethered back to the computer. I had also previously gotten two RF radio chips to talk to one another, but I hadn't figured out how to attach any additional sensors and report that data. Above is a Parallax Ping))) ultrasonic range finder hooked to an Arduino development board, which has mounted to it an XBee RF radio. With the 9-volt battery pack it is completely autonomous - that is to say that it is physically disconnected from the computer. The Arduino is running a program that samples range data from the sensor about ten times per second, and then broadcasts that data over the XBee radio. Back at the computer I have another XBee radio that receives that data and pipes it into the computer via USB. At this point I could do lots of interesting things with the data. As an example, I could store it in a database for charts and trends, and even display that chart in real-time across the Internet. In this case I use a simple socket server that takes serial data from the USB port and broadcasts it to any connected program. The connected program here is a Flash-based, Adobe AIR powered application that shows the distance in inches. The wattage of the XBee radio I use here is capable of a 400-foot range, and I proved that by walking around the basement with the sensor and seeing my computer screen update in the distance. More powerful XBee radios can broadcast even as far as several miles. I know full well that this isn't particularly impressive in the world of electronics, but it's a start. My start. There are many other far more ambitious Arduino-based projects already out there, but I feel like I've finally made that leap to getting outside the box. I have a few different projects in mind for myself, among which includes remotely flushing a toilet, and building some very interactive Halloween and Christmas displays. You know, the useful stuff, like rebuilding an vehicle engine.

Note: this item is rebuilt. But, it's a steal at $4000.00 1963 chassis made in East Germany by Peitald in their now defunct Rostock factory, fully deserreted in my shop and adapted for ongoing alternating ablation in incremental, residual and patabberal sequences. No audible included, though wide range of Vreiss inculment ‘phones are available online. I redecked the onsor tripod five years ago down to the knuckles, nickle-plated the insert rods and adapted the lens platform for a quick reset from glaciology to PFP, so no downtime in between jobs. Focal regress is set to range between 1:33:9099.01 filtered and unfiltered. Nominal energy loss uninsulated, though obviously full shield protection is still necessary. I can also sell you a windred helmet with 3 plates if you don’t have one, with an RT2 rating. Photo accurately depicts the 6 arms – I remodelled for Seite use on dual planes, though the two antal arms can be shut down independently when not in use. Inset pic displays the elantin relays which are new, lead base is original though cleaned and oiled regularly. Power source standard or battery, and I’ll include one 33Pk fully charged at no extra cost.
