Side Project
Log from Delta Printer - Capacitive Nozzle Probe
A digital bubble level was built to measure the platform tilt over the travel range. This consists of an ESP32 dev board with 1.9" LCD and Sparkfun ICM-20948 breakout board. The base was small enough to mount on the effector...

Project journal
Log from STEbus Z180 slave board (SP180)
2024-01-20 I've just found and bought this board from eBay. Made by DSP Design Ltd. It uses the 7-thou pitch DIL packaged device (ugh!) which can only access half the memory of the PLCC68 version. I don't expect this to come with a manual or circuit...

Goals and Motivations
Log from Poetroid - Poetry Capturing Camera
The goal is to create a portable and self-contained instant-style camera that prints poems instead of pictures. Some of the motivations for this project: - A desire to create a fun art project to share with my friends while playing with my favorite things: impossibly...

Part: The SBC
Log from Poetroid - Poetry Capturing Camera
Ideally, Poetroid runs the language models on board. Currently easier said than done. I initially wanted to find a low-powered board that could run the language model itself. While it is possible to run the models on many SBCs, according to the...

Lawnny gets a makeover!
Log from Lawnny Five
There was one benefit to the unfortunate RUD (rapid unscheduled disassembly) of my motor controller in my last build log— it gave me an opportunity to spend some time on quality of life improvements. A fresh coat of paint Lawnny is an outdoor bot, so...

v 0.1 -- the inevitable first prototype failure
Log from Plasma Toroid (sky-guided PCB edition)
Whipped up a prototype PCB in KiCAD, ordered a batch of parts from Digikey, all set to go, yeehaw.(not pictured in the above schematic: power LED and some other board affordances.)Of course I knew that this probably wouldn't work first-time, but I still...

v0.2 -- First Light!
Log from Plasma Toroid (sky-guided PCB edition)
I'll put the cool part right up top: it works. (and i blew up zero mosfets in the process!)Version 0.2 boards arrived lookin' nice and spiffy. Everyone else I've seen who does a variant on this project uses a primary inductor made either of regular...

i would like my circuit to not cook itself
Log from Plasma Toroid (sky-guided PCB edition)
First Light accomplished. What did I learn?The circuit in its current iteration,1: gets hot alarmingly quickly2: is trying to draw more power than I can actually supply. Those seem related, yeah. apologies for the excessively american temperature...

tweakin'
Log from Plasma Toroid (sky-guided PCB edition)
Spent a big chunk of the weekend adjusting a variety of component values. Here's the waveforms with the circuit unloaded (no toroid), at 18V supply: Yellow is Gate (5V/div), purple is Drain (50V/div), blue is feedback network bias input at TP5...

Version 0.3 is calm, cool, and collected
Log from Plasma Toroid (sky-guided PCB edition)
Revision 0.3 of the induction driver creates a plasma toroid that's stable and controllable, and does so without overheating. I'm closing in on a finalized version of the driver. Soon, both the induction coil and driver circuit will be unified into a...

Components List (Mostly) Complete!
Log from Reverse Engineering an Apollo-Era Circuit Card
First step in any reverse engineering process is pretty simple - "What the heck are all of these parts?"Thankfully, the designers were kind enough to label everything, and while the conformal coat has yellowed with age, it's not completely opaque. So...

Traces and Nets and Pads, Oh My!
Log from Reverse Engineering an Apollo-Era Circuit Card
Yeah, yeah, it's Paint3D. It's better than you think, I swear!With our components pretty much resolved, it's time to answer the question of "how does everything go together?" Well, the step in that is to get a map of the nets on the board, and start...

Step 1 - Solder and verify
Log from KS Zigbee Gateway
The board has been assembled to test the circuit's functionality. Zigbee module was mounted on the board right after DAC verification. The most challenging part was soldering the DAC chip and then, a bit easier was USB-C soldering. Quick examination...

The hardware design is taking shape
Log from Desktop Thermometer
So have updated the source repository to include the hardware design and the rough layout for the board. None of this has been bread boarded yet so all untested but as they say, what could possibly go wrong?There are two variants of the hardware, one...

And the solderless breadboarding begins...
Log from Desktop Thermometer
I know some people love this stuff and I know that this is necessary before going to copper boards but it is really something that I do not like all that much. I think the thing about it is that I design the schematic in such a way that it is easy...
