We have most of our related devices on switchable power strips so they can all be turned off with the flip of a single switch!
So I broke down and ordered a bukkumi bag from Switch when they were temporarily in stock. :B The box was huge! The package was cute, but I must say I was really hoping for one of the faceupped heads. Ah well, I do like the wigs I got, but I'll probably sell the Haji.
Most of microcontrollers work within 5 volt environment and the I/O port can only handle current up to 20mA; therefore if we want to attach the microcontrollers I/O port to different voltage level circuit or to drive devices with more than 20mA; we need to use the interface circuit. One of the popular method is to use the Bipolar Junction Transistor (BJT) or we just called it transistor in this tutorial. For more information please visit www.ermicro.com/blog/?p=423
Switching duties in the Benicia Trans-load Facility are never dull or boring during the day. Once night falls, the life around this area becomes even more interesting!

A couple of days ago, the dishwasher handle switch gave up again - Sugru wasn't rigid enough to hold its shape under regular compression and friction. So I measured out the critical dimensions, designed and printed off an insert to address the worn-down nubs.
Of course, once that was addressed the electronics died completely! They were already only half-working, but the previously-glitchy switches were probably what killed them in the end.
Replacement board(s) ordered. Once those arrive though, I think I'll reverse engineer the broken board and open source the results. Who knows what may result? ;-)
A healthy cut of inbound empty cars holds the main as L555 pulls out of the mill and stops short. The Hayward Branch would make for a neat model layout given it's handful of mill spurs and small siding. Operationally, they build the outbound train, spot the inbound cars, then back the whole train out to Hayward Jct. using a caboose to protect a number of crossings. February 18, 2013.

This pair of doodads lets me have up to 9.5V of switched, regulated power on my KAP rig for driving video hardware. The switch in the upper left goes in my RC transmitter. The circuitry in the lower right goes on the rig. Here's how it works:
The switch is a quad-pole, double-throw switch. Three of the four poles wire into one of the channels on my transmitter. Two 5k potentiometers are wired into the switch, which will feed the signals from one or the other into the RC radio. By dialing in two settings on the two potentiometers, the switch lets me flip between the two.
The fourth set of poles is used to control power to the video hardware on the ground. Flip it on, the hardware powers on. Flip it off, it all goes off.
Meanwhile up in the air, an RC switch from Pololu Robotics is wired into the channel that is tied to the switch on the ground. When the ground switch is flipped on, the RC switch powers on. When it's flipped off, the RC switch powers off.
The switch, in turn, is wired into a 2.5-9.5V boost regulator, also from Pololu Robotics. (They also make one that goes up to 25V.) This boosts the +Vbatt and Gnd lines from the RC channel to a regulated +9V and Gnd on the twisted power lines coming off the two boards. This plugs into the video transmitter on the KAP rig.
The net effect of all this is a switch on my transmitter that turns ALL my video gear on and off, both on the ground and in the air. It also eliminates the need for a second battery on the KAP rig strictly for the video.
A hidden benefit of this is that as long as the supply voltage is above 1.5V, the boost regulator will continue to supply 9V to the video hardware. I'll notice the sluggish servos on the rig long before the video will fail.
This was taken when I was in the Bladnoch Distillery in Scotland. It is the main power switching room for the Distillery. I only had a few second to get the shot as I wasn't suposted to be in the room, with a little but more time I could have pulled together a much better photo but I do still like the craziness of the number of switches.
