Not for the Maker Faire. I dropped out of San Mateo’s faire this month, stayed in for October in Austin. It’s next week anyway, not two weeks.
No, two weeks more before the end of finals, after which I can safely and responsibly be obsessive about hobbying.
I haven’t done a lick of work, since I had [...]
A day later I learn from a page on the Seattle Robotics Society’s web newsletter, Encoder, that I can in fact solder those tiny bug sized IC’s that left me itchy yesterday. In fact I can do it using a toaster oven and a special ordered compound! It looks like a fun experiment, but unfortunately at this point [...]
I have the cycles of the washing machine measured at last. I am ready to build a circuit.
I thought I would start with the easiest one first. All it does is light an LED when a load of almost any kind comes through the wire. The voltage just has to make it through resistor R5 [...]
Forget about that claw I posted about earlier. It looks cool but I couldn’t find a multimeter to work with it. The first one I purchased for $10 that didn’t have a “range” indicated in the claw’s specs. as you know. I went to Discount Builders with the claw’s booklet. It says:
The 72-555 is designed [...]
How to:
Measure Current (and why)
First of all why not measure voltage (V)? Isn’t “high voltage” the thing that’ll kill you. The mover and shaker of all the electromechanical world we live in?
Well not technically. Technically current is the killer app, measured in amperes (A) but annotated as “I”. Voltage is [...]
