In this post I want to share how I selected a suitable topology for the resistor network that will be the core of the programmable decade resistor. Although I did some online “research”, the following criteria determined my choices: Switch...
I had heard of the rpitx program before - it uses a PLL on the Raspberry Pi to generate RF signals directly. I'm not sure what the bandwidth is, but I saw a reference to someone transmitting HDTV signals with one, which would imply 6 MHz of bandwidth,...

This is the original, 74 year old speaker in this unit. While I probably won't use this for the primary audio output, I do want to have it functional. Zenith was really thinking outside the box when they designed this unit. One of their unique ideas...
Development Day 34-start of flat rotor selection logic-couple of bugs when returning rotor to box or returning from plugboard when flat rotor is visible-Rotor type/position goes correctly from upper or lower box to center-need to delete it from the top...
The TLDR is that OAK-D was a hit. Folks love the capabilities, and it makes solving all sorts of problems WAY easier. It is the cheat mode for interacting with the world that we thought it would be.But... it is too expensive for many...
It's off. It's gone. It's in the mail. Somewhere between Pennsylvania and California is the travelling box of hacker crap.A few changes: I needed to use the Large flat rate box. The Harbor Freight box was unexpectedly out of spec and didn't fit in the...
@jlbrian7 got a box from @Sophi Kravitz , and it's now in Latvia, in MakeRiga hackerspace. Next stop is likely in Estonia, unless @Benchoff advises otherwise. Box: Yes, it did cost $93 to ship =D The books are great! It seems that...
Sensors deployed in industrial applications tend to work quite reliably, until they don't. Typical failure modes include cable breakswater ingress and electrocorrosioncontamination with process mediarange and drift (mechanical, electrochemical)wear (abrasive,...
One of the example programs bundled with the Fluxamasynth Arduino library is an interpretation of Terry Riley's 1964 algorithmic composition In C. It shows one way of encoding a composition with multiple parts and an adjustable master tempo. In C was...
Technology Level I want to make use of parts from my junk box wherever possible, whichmeans largely using 74 series TTL and parts from a similar era. Any newparts that I buy will probably be 74HC, as TTL is becoming hard to getthese days. There will...
Wire Wrangling At the same time that I was having the Transition Table Reader board made I had a small PCB done to help wrangle the wires from the eight servos. I just added headers to allow me to plug the servo connectors into the board with the...
So far the neotrellis is a somewhat pretty blinkie toy. We can make it a bit more useful by turning it into a 16 button Midi keypad. That is having each key send a different Midi Note over USB. Press and send Midi.NoteOn, Release and...
OverviewSo we looked at the basic ways with hooks and RAWINPUT.Windows has filter drivers, these basically sit on top of the existing drivers and can modify what the base driver does, simply a filter.MSDN Filter DriversSoftware NeededWe will be looking...
The amazon fairy dropped off a "NES Classic Controller" and a "Classic Pro"The classic pro comes up as a classic controller, The only difference is the analog R and L on the one I have are buttons and just return the max value when pushed. Although this...
