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...

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...

Daemonization
Log from Adventures in Rust
Daemonization is the process of detaching from the invocation environment. For Linux processes that are to run as a system service, the most important things to do are to detach (and optionally reattach to files) the standard file descriptors stdin,...

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 2 - Forming it all up
Log from KS Zigbee Gateway
The application skeleton for ESP32 (main CPU) was built on my ksIotFrameworkLib, which provides some fancy stuff like device configuration portal, MQTT support, LED management etc. Then the E-180 module has been studied in relation to firmware update....

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...

Programmer/Debugging Board
Log from Desktop Thermometer
While I am waiting for the boards to arrive, the time could be spent explaining the idea behind a separate programmer/debug board. As mentioned in a previous post, there is no way of programming the microcontroller while it is installed on the...

"Season 1" Part 1 (Early 2019)
Log from Somewhat 3D printed backyard railway
A bit 'o BackgroundEver since I got to visit a "Riding Railway" somewhere in Western, MA (US), I've always wanted to have a backyard railway that:I could rideHad some sort of purpose (moving firewood, rocks, etc)I've been interested in trains my whole...

1 - MIXING MODULE
Log from Digital Audio Mixer w/ Filters & Multiple USB I/O
In the general description of the project, I briefly mentioned the 4 core units of the project : a general use input module to be able to get analog data ina general use output module to be able to get analog data outan HID module to interact with the...

2 - INPUT MODULE
Log from Digital Audio Mixer w/ Filters & Multiple USB I/O
What is it ? The Input module doesn't technically needs to exist for a purely digital system, but as I plan to use this with analog devices (microphones and instruments) so I am designing it. This module is therefore separated in two specific part :...

Research
Log from DIY Digital Caliper
I was think that I need get my hands on a a caliper first and disassemble it. To be honest I did not get any super interesting information out of that. I just ruined perfectly good caliper. The t-scale PCB is 0.5mm thick and has copper only on one side...
