While I'm obviously very into KiCad and think it's a better choice, I don't know if the plane argument is fair. Wrote about it here: https://contextualelectronics.com/learning/simple-plane-experiment-kicad-vs-circuitmaker-vs-upverter/

just add 60Hz +-5Hz notch filter, and that will work just fine

@MattRichardson has gone Maker Samurai. Awesome!

I like the TindieU idea, that will be useful! Now if anyone needs to learn about the electronics side of things...

NI also makes PXI versions of SMUs. But Dave got it right with the other 3 vendors.

Sorry to hear about Lew Soloff's passing. Got a chance to hear him wail in an impromptu jam session the last time I was in NYC (Sep 2014)

DMD + MQTT: Difficult, but doable (as Toby showed)

Getting an Android device to understand an Aussie: Extremely difficult :-)

For anyone interested, the windows MQTT download...

http://mosquitto.org/download/

Example code under arduino ..

 client.publish("outTopic","hello world");

Under windows,

Mosquitto_pub.exe -t "outTopic" -m "hello world"

Python,

client.publish("topic", "hello world")

Linux,

sudo Mosquitto_pub -t "outTopic" -m "hello world"

As you can see, pretty easy!

A video I put together about how I built my flying camera arm for my electronics workbench.

Nice job Chris!  If you want to avoid the split-out from the screws, just pre-drill the holes with a bit about the same size ( or slightly larger ) of the screw dia. not including the threads ( barrel? ).

The family that cleans up crap on a workbench together....stays together. That's how the saying goes, right?

+TheBdd4 $18 is nothing for a one-off precision current source like this. 2 terminal ones aren't much cheaper, if any.
