Doubtless those who complained about the ramps in the road works will be heartened to see the quality control messages!
I was challenged to have a go at painting with light. I don't appear to own a torch, but I spotted Amber playing with her flashing light bouncy ball earlier and thought I'd have a go using that. It's the first time I've really tried long exposures on my camera - it was fun! Have to say though it certainly isn't easy controlling where a bouncy ball will bounce...!

I suppose a more tech-savy term would be "interface," a device that enables a programmable thermostat to control a 40 amp contactor. This is temporary, until I have time to build it inside a tidy steel box.
Here is the tracker control system in its deployment configuration – the card is the same size as an Arduino Uno . Socket at left holds the Arduino Pro Mini clone (ATmega328 5V 16Mhz). Socket at right holds the A4988 Stepper Motor Driver Carrier. Single 2-pole screw terminal block, right front, connects to the HOME sensor switch. The pair of 2-pole screw terminal blocks, right rear, connect to the four leads of the stepper motor.
The 6-pin right-angle header on the nearside of the Arduino Pro Mini clone can be connected to a USB-to-Serial converter, but is only used to download programs from a PC onto the Arduino.
Note the 9 VDC battery cap. I intend to power this system from an external power tank, because I plan to add a current hungry, FET-driven, anti-dew heater controller to the empty real estate on the board. However, for the time being, what with the stepper motor being powered at a 0.8% duty cycle, I actually think I can run the tracker for several hours on a standard 9V battery.
Just in case anyone was thinking of lighting a fire here...

My husband said to me that these pelican's are on Cruise control. They move really fast.

Over 11,000 feet of crowd control for Parades, Concerts, Political Events, Festivals, Demonstrations, or any place where pedestrian safety is a concern.
Use to restrict areas and channel crowds to where you need them to go.

We got to watch a valve blowdoown test today. This is the control that throttles the steam through the system -- it's impressively precise.
I went out to the pond to feed the ducks and when I came back I was covered in "hitchhikers." At least that's what we call them.
Magna loves them so I thought what better way to remove them than with her help.
PRC Beijing Police SWAT Riot Control Vehicle. Notice gas launchers, dozer blade, cameras, and possibly a microwave based crowd control device mounted next to the gas launcher.
