See Update BelowContext being more that of the puzzle of cases not one case "to rule them all," but I digress. The past week I've been going through a few catalogs to find an enclosure for D-DAQ's mainboard. Previously, the PCB's form factor was based...
Stephen : Alright, let's get rolling. A BIG hello to @Parker for joining us today Parker : Howdy everyone Stephen : @Parker, why don't you kick this off by giving us an introduction of who you are, what you do, and what...
I love it when I can find parts that someone else designed, it saves me time and effort. Aviator67 produced a treasure trove of add-on parts for the farscape1 LUT. After printing and assembling the Level30 floor framing along with the cable tray template...
Found out about the Tinymovr motor controller. Basically what I'm trying to do! Very cool, and my version 2 will use it as reference. I hope to make mine even smaller (27x27mm vs 40x36mm) and cheaper ($40 vs €89). I only need up to 13V (3S lipo),...
It was dumb to use a DC motor for this project. I should have just ponied up the resources for a high speed stepper. My plan was to attach a rotary encoder to the DC motor to accurately measure the number of rotations. This is not easy....First, I tried...
The weather conditions have been terrible in Chicago for the last 7 days. There is no way that anyone in Chicago has been able to support plant life outside.
I've redesigned the way screens/apps are handled and introduced a main menu. More importantly, I have managed to get the average current consumption down to 350-550uA (1.5mA previously)! Turns out a huge chunk of it - 800uA, was a bug in the TWI (I2C)...
Before I began the layout of the DDL4-CPU, I came up with an initial Instruction Set Architecture (ISA) for the design. It went through several revisions as I was designing the boards and refined the components. Here at the last minute as I am...
After a sinuous but exciting road, the Beta prototype came out nice, the entire device is amazingly small: I was able to design it to fit the 110x70mm aluminium enclosure I planned initially without renouncing to any of the sensors nor reducing the 1500mAh...
In this post, I'll walk you through how the latch works. Later we'll walk through what's causing the problems. Two Mechanisms There are two mechanisms for opening the latch: the lever outside the door, and the knob inside. Outside lever Inside knob The...
A bluetooth tag that supports Eddystone / Ibeacon BLE protocols is used. This would allow the ESP32 to monitor human behavior that may have influences on pollution. With each Eddystone TLM(Telemetry) frame we would extract the beacon count and its associated...
This is the second test after removing the bad PSU from the loop to test equipment. It is raining outside now so we will have to wait till we can get it outside. There are many goals to this project and we are tackling them one at a time. This test is...
As for today, I successfully tested the BlinkWithoutDelay on my standalone board (custom designed by me). This video can be found below: Next step will be uploading my custom sketch to it and actually testing how it works in the wild (outside home, supplied...
