Man crosses street in front of Hi-Tech Electronics store, Manhattan
I made this photograph on a quick walk through a slightly seedy area of Manhattan, passing through on a hot afternoon as many people filled the streets. (It actually was crowded, despite the appearance in this photograph.) The area is one of somewhat run-down businesses in one of those pockets where there are not so many tall buildings.
I see many things when doing street photography. Some of them are static enough that I can take some time to make the photograph, but others happen instantaneously and are gone in an instant — they require a "shoot without thinking" kind of response — and that was the case with this one. Obviously, the man walking toward me was only there for a moment, but even better was the brief conjunction of red things in the frame. A close look may reveal even more of them that you notice at first.

В коробке с карандашами недавно прошел дождик
Любуйся теперь, художник, лампами и запчастями.
В коробке с карандашами Tesla триод-пентод пляшет
На желтом песчаном пляже с весёлыми голышами.

The Quantaray lens does not mount the D40 but was held backward against the D40 camera body by hand. The Quantaray lens was originally used on my Minolta XG-M. The lens is 28 years old! Who needs to go out and buy a fancy macro lens when you can do it with lenses you already have! Just make sure they have aperture rings. You won't be able to use any auto functions or metering. It's manual focus all the way using your feet or arms to get the correct focusing distance.You alse need lots of light.
This was an electronic car starter. I found it on the ground in pieces. I thought it would make for a good macro photo.
Dick Smith Electronics at Westfield Whitford City Shopping Centre at Hillarys, in Perth's outer northern suburbs. This was following the receiver's sale with the announcement made on February 25, 2016 that all stores (301 in Australia and 62 in New Zealand) would be closing over the following eight weeks with sale starting the following day February 26.
These shots were taken early April 2016 around half way through the closure process. Notably Dick Smith branded TV's have been more difficult to sell with customers wary of warranty issues due to the retailer's demise. The Dick Smith online business has been bought by Ruslan Kogan and was intended to be relaunched in June 2016, but instead was done after closure of the final stores on May 3.
I soldered up the amp I designed. It's horrifically inefficient but sounds beautiful! Only got one channel for the time being but maybe I'll make up another...

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.
Some comparison photographs showing the size/weight/style differences between the Bronica S2a and Mamiya M645J. These are for a review I'm putting together on TalkPhotography for the "Massive Film/Conventional Camera Review" thread;

The front panel is quite nice. It is clear plexi with a printed adhesive sticker (looks like thin vinyl) applied to the back side. The screws here are what you want to remove if you want to get inside.
Slightly updated PCB. Now the boards are blue, the pads are gold plated, only 1mm thick and the silkscreen has been revised and now shows Arduino pin functions for PORTC and PORTD.
This batch of 25 boards was made by MakePCB.com - very affordable but also quite slow. My first order took about 5 weeks. GoldPhoenix just took about 1 week, but at a higher price.
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.
In design, Epad ZT-180 looks like the original iPad. On the left side, it has 1 USB port, 1 mini-USB port, 1 HDMI port, 1 headphone jack, 1 MIC jack as well as 1 DC jack and 1 TF card slot to expand the memory. On the other side, on-off key, volume buttons you can see in the pictures. But what’s difference with iPad and Zenithink ZT-180 is 7 inch TFT resistive touch screen (1024*600 pixels) display with a HDMI port.
A 1.3 mega pixel camera will be one of the high points of the Epad ZT-180. With the webcam, video chat for business conference or connecting with family and friends can go anywhere anytime. What’s more, this pad also supports external 3G, Bluetooth function, G-sensor, Flash 10.1, PDF, Office software, eBook etc. Besides, the battery is 3000mAh, work time about 4-5 hours, multi languages are available.
Frank speaking, the tablets take the place of PC won’t be impossible. It is a useful supplement. But the era is Android world, open and free. Hope PC can run Android OS in future. Lastly, according to Vkamobi, China Wholesale Electronics, Epad ZT-180 costs less than USD0.00, quite affordable.

This is a Signal Generator. This URM-25 was made for the Navy by Federal Manufacturing & Engineering Corp. of Brooklyn, N.Y.
My sample was made for the "Navy Department - Bureau of Ships" and probably dates to the early 1960's. This thing is a beast! It weighs about 25 pounds and is built like a tank. It appears to work well (I have tested it). My one criticism is that the frequency divisions appear to be a bit coarse. It may be that I just don't know how to read it correctly.
This one will be a bear to clean up. It has paint spills (upper left corner), tape marks, and permanent marker labels all over it. But then that's how I get these things for almost nothing. Serial number is 214.
(I'm told you can hook a microphone up to these and get on the AM band, just like those Fisher-Price radio mikes.)
-and yes, I do have the cover but the manual and all the accessories except one are gone. I got a Navy manual off the Internet ...some 90 pages...have to read it sometime.-
