So it looks like a company called SKYHOOK Wireless is powering the Wi-Fi location services in the the new iPhone 2.0 update. This is good news for first generation iPhone users as it adds really very good positioning to the cell tower service from the 1.0 release. What was interesting to me was how they […]

IR interfacing with a LED messgage sign, part 3
Code finished, uploaded, time to take it out for a test. I wired up everything, confirmed that the IR LEDs were in fact lighting with my digital camera (FYI, IR LEDs will glow with a purple tint to them when viewed through most cameras). The first test was unsuccessful. The sign taunted me with it's […]
IR interfacing with a LED messgage sign, part 2
To make the Arduino transmit IR signals, you need an IR LED. I found a couple from an old Sun optical mouse and an old TV remote control. I used two emitters because that's what the original Pro-Lite remote has inside and it also gains distance (I hoped). I should probably be connecting these LEDs […]
IR interfacing with a LED messgage sign, part 1
We've had this ancient LED message signs made by Pro-Lite at work ever since I started. They were controlled by an equally ancient IBM PC that has since vanished along with the software and much hope of being able to use them again. There is a seemingly RS-232-ish port on the back with pins 2 […]

A recent visitor to a DSWA electronics recycling station
Jeff recently visited a DSWA electronics recycling drop off station to depart with an old CRT television and shot these pictures. Walking into the drop off box is kinda like taking your life into your own hands, walking around haphazardly placed televisions and other equipment that could easily fall and crush your legs. Fun! A […]
Video: Young nestlings being fed
Here's a short video I shot of the four baby birds nesting on the pergola being fed by their parent. It's amazing to see how quiet they are until the parent makes a chirp erupting them into a frenzy. I believe these are robins, but I'm not 100% sure.
Reminder: Charge your NiMH batteries!
A reminder: charge you NiMH batteries if you haven't used them in a while. NiMH batteries will loose their charge in storage rapidly so you need to pull them out periodically and top them off. I have 6 sets of four NiMH batteries around, mainly for use in my speedlite flashes. I have to remember […]
