Electronics Tech. My happy place is designing and building instrumentation. Also into bikes and geology.

A breadboard with an Arduino Nano and various other components documented in the project write up.
A breadboard populated with an Arduino and various modules has four different voltage rails coming in off a power supply.
PCB where I have to stick a resistor under a MOSFET because I made a mistake.
(See previous post)
A DMM screen reporting "V Floating" when the leads aren't touching anything.
Giga DMM showing a reading of 5.0008vdc off a 5.0000 source (because of the divider this is within 2 steps of the ADC smallest unit). Also a plot showing the actual reported voltage by the ADC is bouncing between 4.996 and 5.003
Showing the internals
The DMM reading a 1 ohm resistor.
Electronics benchtop
A small DMM in a printed housing, about 2x3x1" big
Meme with the 24 bit ADC all fancy while the 16 bit looks plain.
An electronics breadboard with circuity surrounded by a homemade DMM, a normal DMM, and a handheld scope, showing 20mA running through the circuit.
Cycling my basement lights through different brightnesses.
Arduino Uno sized PCB in a small box, turned on with the display reading 0.
An Arduino DMM reading a battery and connected to an ammeter module.
Mono Lake and Yosemite from the air
Screenshot of run results
Screenshot map of a half marathon run.
A cardboard box with handling specs, including a min max for temp of -40F to +70c.
A Raspberry Pi in a case using a video production capture monitor as the display.
A custom, homemade DMM that uses an Arduino with a display and acrylic front and back.
I’m holding an Arduino based DMM with a pile of about 5 previous versions in various states of disassembly next to it.
Homemade Arduino DMM that has no screen, with a GUI on a laptop screen in the background, reading ~15k ohms.
Small closed 3D printed box
Three DMMs, one commercial normal one and two homemade prototypes.
Partially assembled PCB
Arduino sized PCB ready to be populated.
