What are your favorite hardware tools that you use?
I love my Metcal 500 and all the great tips you can get, like the hot tweezers which are great for rework. I’m also tied to my Tek 2014B although the probes are a little wonky lately.
What are your favorite software tools that you use?
I like to use a range of open source tools like avr-gcc and xemacs as well as Arduino, Processing, and Fritzing. For layout I learned on EagleCAD and I’ve gotten pretty good at it.
What is the hardest/trickiest bug you have ever fixed?
Debugging the SpokePOV – a persistence of vision display on a bike wheel – was really annoying because its hard to figure out why your interrupts are not going off while its spinning around at 10 mph. Eventually I figured it out but it was really frustrating and took a – long time –
What is on your bookshelf?
I have classics like Art of Electronics and Troubleshooting Analog circuits as well as the ARRL experimenter’s manual and Grebene’s Bipolar and MOS Analog Integrated Design.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
