DIY 16-bit precision voltage source with MAX5717A DAC
If you need a precision voltage source, you have three options. You can spend thousands of dollars and buy a lab instrument from a reputable company, you can spend hundreds and get an amazing enthusiast-grade device from Ian Johnston, or... If you're a cheap ass like me, you can build your own device that might just be enough for your use case at a fraction of the cost, and with hours and hours of fun included for free. Guess what we're going to do!
26 AWG solid copper wire: the perfect choice for hand-soldered Arduino projects
This post is my little token of appreciation for the 26 AWG solid core copper wire. Perfect for creating permanent version of Arduino projects, or if not perfect, then at least much simpler than wire wrapping and much, much more practical than using solder traces. Man, I love 26 AWG solid core.
Using a FLIR thermal camera to improve the taste uniformity of a tea-infused cake
Making a layer cake is a serious task. There are... layers... of complexity to it. Make a mistake, miss a step, and the whole thing can turn into a disaster.
Quick look: Voltage drift / instability on Ruideng RD6006 power supply
This post is a quick record of voltage drift / variations I noticed during recent experiments with using a MOSFET as a voltage-controlled resistor, where the MOSFET's Gate-Source voltage was driven by the Ruideng RD6006(W) DC-DC power supply.
TL-21 Kelvin clip test lead upgrade for DER EE E-5000 LCR meter
There's no shortage of blog posts and videos describing TL-21 probe upgrade for the extremely popular DER EE E-5000 LCR meter. With that said, this post will is somewhat repetitive, but hey, I already took the pictures, so why not share.
For impatient readers, this is what the finished job looks like:
Measuring breadboard wiring resistance: how bad is bad?
This article is a brief record of my early breadboard wiring adventures, because learning things the hard way is fun! You may also read the related post if you wish:
