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.
A new generation of cheap lightweight plastic electronic technology that does not require silicon, but which is optically transparent and can be coated onto everyday objects would transform our world.
"Working collaboratively with industry is not only satisfying in that I see aspects of my work translate into real engineered products, but it provides inspiration for new avenues of research too. Roadmapping then allows me to critically assess how I should be developing my research portfolio and engaging with industry to maximise the likelihood of productive collaboration."
—Dr Andrew Flewitt
Imagine electronically updated food labels, computers embedded in our armchairs, even contact lenses linking us directly to the Internet to bring us into the age of plastic electronics. In this video podcast Dr Andrew Flewitt and Dr Robert Phaal both from the Department of Engineering and Scott White serial entrepreneur and CEO of Pragmatic Printing talk about the creative partnership forged between different parts of the Department of Engineering and outside companies that enable the technology and research in this area to be exploited successfully.
CNC electronics enclosure with a switched-mode power supply, a solid state relay for spindle control, three A3977 based stepper motor drivers for x, y, and z, a controller power supply, and the controller board. The controller is based on Microchip PIC18F8680, and the milling program is read off a USB stick using a VNC1L (the board is not shown). The whole system is controlled using a graphical touch screen LCD.

Some shots from the electronics flea market. I took these around 11 when I was done browsing, so a lot of vendors had already left or started packing up.
Robot3 has an IR rangefinder, one of my STM32 development boards and an xbee radio running the new ZB firmware. There's also a small motor controller board hidden inside the old battery compartment as well as a 900mAh lipo. The rear two wheels are driven by one motor which is speed controlled by a PWM output from the STM32, while the front two have another motor on a rack and pinion that steers them and is driven by a simple high or low signal from the STM32.
The car can be manually remote controlled over the xbee wireless link but automatically backs away from detected obstacles. Alternatively it can simply drive forwards until it detects an obstacle, then reverse away.
Development slowed once I got the parts for the somewhat more interesting quadcopter UAV.

Phmeter, oxymeter, spectrophotometer, somethingmeter, and various stuff... Now the real, big question is: WHAT THE F*** WILL I DO WITH IT ?

My electronics bench, oscilloscope and power supply project. The oscilloscope is an HP 54501A 100MHz 4-channel scope I picked up for about $250. The power supply is a variable output DC power supply with about 10 amp output capability. I made it from scratch.

Another implementation of the classic two transistor Joule Thief circuit, made entirely with surface mount components.
I have glued the board on to the battery holder just to neaten and finish the project.

Digital storage adapt0r. This Thurlby DSA524 will turn my 1970s Hewlett-Packard oscilloscope into a 1980s digital storage oscilloscope.
The bandwidth is 5MHz, which will allow me to see the rise and fall of waveforms produced by 1970s digital electronics fairly clearly.
It also has tons of buttons and red LEDs and beeps when you switch it on.
Oh and an interface port that allows you to connect it to a BBC Master Microcomputer.

M2 Torx. No traces in the way.
Death to Phillips screws and other stuff that cams out way too easily, ruining the screw in the process.
Question: What the heck is PONG supposed to be?
When you're playing it, it feels like the video game representation of some real-life sport. You're bouncing a ball back and forth with another player, which at first glance sounds a lot like like table tennis, AKA ping pong-- and that would seem to explain the name. And yet, PONG is two-dimensional and free of gravity. The ball goes in a straight line, at a fairly constant rate of travel. And you don't play ping pong by rotating a wheel. Come to think of it, it's not a darned thing like ping pong. So what the heck is it?
To answer this, we built this real-life Tabletop Pong game. You can read more about this project here.
