Today I did a quick test of my little ATtiny85 microcontrollers’ capabilities. I had them sitting in a jar for a while, and I wanted to see if I could use them in conjunction as a coprocessor to manage some mundane task like regulating a motor. I have previously written …
I’ve been playing around a little bit with LIL on my ESP32 arduino. It works, but there are a few things I don’t like. LIL isn’t object-oriented by default, so I can’t do a lot of what I am used to writing code in Javascript and …
I have been working really hard this week on Schemascii. Like, maybe too much. But, I finally got Schemascii to the point that I could (if I wanted) upload it to PyPI and it would be a valid package.
Schemascii is also able to be called as a command-line program …
I spent the last two days fooling around with my half-idea of a diagramming program, Schemascii. What it’s supposed to do is be able to make a diagram of a circuit (like the ones you might make in Eagle or KiCad before you plan a circuit board) out of …
I’m starting to finalize the circuit boards needed for my Roboraptor upgrade. I am doing everything with THT components, which take up a lot of space, but I can solder by hand easily. Unfortunately, this means everything takes up a lot of space.
The top board, which will go …
Congratulations, you have reached the end of this series.
I finally found a programming language that I can use on my Arduino: LIL, written by Kostas Michalopoulos. It’s a lot like Tcl (but not quite), and it has a simple to use C API so I can add custom …
Over winter break I was able to get some more progress done building circuits to get closer to an upgrade of my old, broken Roboraptor. There are a zillion different components to this project, and I wanted to test each separately to make sure they work before I make a …
Today I started work on the Phoo debugger. As-is, it is very simple – I already programmed in a “tick” function into Phoo that gets called every item, and so my debugger only needs to patch itself into this function.
However, the three buttons – “Into”, “Over”, and “Out” – caused me some …
I was working yesterday on trying to root out the bug in Phoo’s online shell; but I never found it.
Currently Phoo works-ish; except that in the online shell, the error behavior is backwards:
Some time ago I ordered one of Parallax’s “Feedback 360” servos for a robotics project I’m working on. I wrote a little arduino library to control it, and it works well.
As-is, however, the servo itself is too big to fit where I want it to. I’m …
