Lab Switch

+ +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. +

+ + + +

What it can do

+ +It has two relays to switch loads of several ampere connected to the +banana jacks on the front panel.
+There are four independent opto-coupler inputs and outputs at the rear.
+In parallel to the relays, there are opto-couplers that can be used +instead if only a low current needs to be switched. +

+  + + + +

Example usage

+ +The images below show the Lab Switch being used to test how power cycling +affects a +Milkymist™ One. +
+The Lab Switch is inserted into the 5 V DC power supply such that +it can switch the 5 V supply and ground. +
+For further control, the M1 is connected to a PC via the JTAG board. +

+ +  +  + +

+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. +
+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. +
+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. +
+A few seconds later, the Lab Switch cuts power and the cycle repeats. + + +

The software

+ +The firmware is currently extremely simple and just handles toggling +via the front buttons and direct remote control via USB. + + +

Future work

+ +The hardware is currently only designed for low "safe to touch" voltages. +
+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 +README. +

+In the future, the firmware will be extended to allow the uploading +of "scripts" that will allow for more complex patterns of interaction. +
+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. + + +

Sources, mailing list, IRC

+ +The electrical design, the mechanical design, and the firmware can +all be found in +the Qi-Hardware git. +

+Development discussions and such happen on the + +qi-hardware mailing list and on the +#qi-hardware +channel on +freenode. + +
