<H1>Lab Switch</H1>
|
||||||
|
|
||||||
|
The Lab Switch is a USB-attached device that has a few galvanically
|
||||||
|
isolated inputs and output for switching loads and signals in a lab
|
||||||
|
environment.
|
||||||
|
<P>
|
||||||
|
<A href="labsw-0-off.jpg"><IMG src="labsw-0-off-small.jpg"></A>
|
||||||
|
<A href="labsw-0-inside.jpg"><IMG src="labsw-0-inside-small.jpg"></A>
|
||||||
|
|
||||||
|
<H2>What it can do</H2>
|
||||||
|
|
||||||
|
It has two relays to switch loads of several ampere connected to the
|
||||||
|
banana jacks on the front panel.<BR>
|
||||||
|
There are four independent opto-coupler inputs and outputs at the rear.<BR>
|
||||||
|
In parallel to the relays, there are opto-couplers that can be used
|
||||||
|
instead if only a low current needs to be switched.
|
||||||
|
<P>
|
||||||
|

||||||
|
|
||||||
|
<H2>Example usage</H2>
|
||||||
|
|
||||||
|
The images below show the Lab Switch being used to test how power cycling
|
||||||
|
affects a
|
||||||
|
<A href="http://milkymist.org/">Milkymist™ One<A>.
|
||||||
|
<BR>
|
||||||
|
The Lab Switch is inserted into the 5 V DC power supply such that
|
||||||
|
it can switch the 5 V supply and ground.
|
||||||
|
<BR>
|
||||||
|
For further control, the M1 is connected to a PC via the JTAG board.
|
||||||
|
<P>
|
||||||
|
|
||||||
|
<A href="labsw-m1-off.jpg"><IMG src="labsw-m1-off-small.jpg"></A>
|
||||||
|
<A href="labsw-m1-boot.jpg"><IMG src="labsw-m1-boot-small.jpg"></A>
|
||||||
|
<A href="labsw-m1-render.jpg"><IMG src="labsw-m1-render-small.jpg"></A>
|
||||||
|
<P>
|
||||||
|
In the left image, power is turned off. This is indicated by green LEDs
|
||||||
|
on both channels. The red main LED indicates that the switch is under
|
||||||
|
remote control.
|
||||||
|
<BR>
|
||||||
|
In the middle image, power has been turned on and the M1 is booting
|
||||||
|
into RTEMS and Flickernoise. One can see two small LEDs (appearing
|
||||||
|
yellow) in the M1 that indicate this it is powered and booting.
|
||||||
|
<BR>
|
||||||
|
In the right image, the M1 has booted into Flickernoise and is rendering
|
||||||
|
a visual effect. This is also indicated by all three LEDs of the M1
|
||||||
|
being lit.
|
||||||
|
<BR>
|
||||||
|
A few seconds later, the Lab Switch cuts power and the cycle repeats.
|
||||||
|
|
||||||
|
|
||||||
|
<H2>The software</H2>
|
||||||
|
|
||||||
|
The firmware is currently extremely simple and just handles toggling
|
||||||
|
via the front buttons and direct remote control via USB.
|
||||||
|
|
||||||
|
|
||||||
|
<H2>Future work</H2>
|
||||||
|
|
||||||
|
The hardware is currently only designed for low "safe to touch" voltages.
|
||||||
|
<BR>
|
||||||
|
It would be desirable to be able to also switch AC mains and to connect
|
||||||
|
inputs or outputs to places that may be at a high potential with respect
|
||||||
|
to other inputs and outputs. For this, it will be necessary to make a
|
||||||
|
number of modifications to the circuit. Some of them are detailed in
|
||||||
|
the
|
||||||
|
<A href="http://projects.qi-hardware.com/index.php/p/wernermisc/source/tree/master/labsw/README">README</A>.
|
||||||
|
<P>
|
||||||
|
In the future, the firmware will be extended to allow the uploading
|
||||||
|
of "scripts" that will allow for more complex patterns of interaction.
|
||||||
|
<BR>
|
||||||
|
For example, instead of using a channel button as a toggle, it could
|
||||||
|
switch a device on for a defined interval and then switch it off again.
|
||||||
|
|
||||||
|
|
||||||
|
<H2>Sources, mailing list, IRC</H2>
|
||||||
|
|
||||||
|
The electrical design, the mechanical design, and the firmware can
|
||||||
|
all be found in

||||||

|
||||||
|
<P>
|
||||||
|
Development discussions and such happen on the
|
||||||
|
<A href="http://lists.en.qi-hardware.com/mailman/listinfo/discussion">
|
||||||

qi-hardware mailing list</A> and on the
