Ultra low cost microcontrollers
Log from 1 dollar TinyML
If the complete BOM for sensor is to be under 1 USD, the microcontroller needs to be way below this. Preferably below 25% in order to leave budget for sensors, power and communication. Thankfully, there have been a lot of improvements in this area over...

Development board sent to production
Log from 1 dollar TinyML
I made an initial development board. This supports both sound-based and accelerometer-based ML tasks. As well as using the LEDs as a color detector. So this is intended to be used to develop and validate the tech stack. And then further cost-optimization...

Supplies
Log from Sound-activated Counting Light
In this demo, a sound module, a WS2812 module, and a MaESP ESP32 OLED are needed, and they all ccan find in MaESP dev kit. Sound module Sound module is the most sensitive to the environment sound intensity, commonly used to detect the intensity of the...

Assembly Improvements to PCB
Log from Gentle Typing Trainer
I had a few problems assembling the PCB into the PVC tube, this was because I had not thought in detail about two things: * how to solder on the wires, so that afterwards the PCB could be pushed into the tube.* how to secure the PCB in the tube. When...

JST SH Plug Wiring
Log from Gentle Typing Trainer
For this a bought an IWISS IWS-3220M crimping tool from Aliexpress as cheap alternative to the official crimper. Given the small size of the SH connector I recommend buying plenty of the SH contact (SSH-003T-P0.2-H), I bought 100 and got through...

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...

Fixing the Real-time Clock
Log from Portable Pi
Out of the box, a Raspberry Pi 4 does not have a real-time clock. When it is booted up, it initially displays the time it was shutdown at - then when it connects to the network, it updates the time via Network Time Protocol (NTP). I fitted a DS3231 real-time...

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...

Need mow input
Log from Lawnny Five
In order for Lawnny 5 to live up to his name, he really needs to learn how to mow the lawn. So for the past few days I've been working on connecting him up to my 30" Toro TimeMaster lawnmower. Here are the early results of this work: As you can...

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...

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...

Finishing
Log from Mini Low Power Geiger Counter
Got the case printed all nice, Used a friends printed that had a textured bed. Test fit all the components and got them soldered up. I uploaded a small video of it in action with a calibrated Caesium-137 source. Radiation module complete! ...

So prototyping is a GOOD thing!
Log from Desktop Thermometer
In my previous post I rambled on about having to plug little wires into a breadboard. It turns out that this is a good thing. I did have a mistake in my design, not with the schematic but the footprint for one of the components. If you have been reading...

Off to manufacture!
Log from Desktop Thermometer
Both variants of the hardware have now been completed and tested on a breadboard. The code which drives all of this stuff is also pretty much ready to go.So it is all off to JLCPCB to get it manufactured. The down side is that it is the start of Chinese...

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 :...
