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 …
Today I did a little more work on my programming language TEHSSL. And in testing it, I discovered some anomalies.
The first one is that – because of a typo on my part – testing TEHSSL will occasionally segfault when it tries to print the type of the “next” object after freeing …
I started writing a new programming language, TEHSSL, a few days ago. Starting from scratch (again!) wasn’t easy, and I’m nowhere near done yet. I have got two things working so far: the garbage collector, and the tokenizer. I have no idea how to handle the glue in …
Immediately after I wrote the last post I stumbled upon the Cognate programming language. It is sort of a weird cross between Forth, Lisp, and Tcl, all at once, and I strangely like it. Currently Cognate is only implemented by a Cognate-to-C transpiler, so I won’t be able to …
Again I find myself scratching my head over a simple scripting language. Yisp (my attempt at re-writing David Johnson-Davies’ uLisp) got way too complicated; tinyTcl (my attempt a re-writing Serge Zaitsev’s ParTcl) leaked memory like a sieve; and MicroPython can’t be extended with custom functions. All I want …
