RTLapseCAM V2: Resin Printer Time-Lapse with TTGO T-Display & GoPro

Not being able to leave well enough alone, I'm onto V2 of RTLapseCAM. A quick re-cap - the purpose was to take time-lapse photos of resin prints (using layer transitions) and stitch them together into a video. In the original setup, the GoPro sat stationary and RTLapseCAM triggered the photos. The result was ok, but it just showed the print rise out of the bed. I wanted to take it to the next level by…

Mazda Miata MX-5 Rear LED Strip Console Controller

Who wants one? I've had interest in making a kit for my original Phase I strip. It would consist of the NeoPixel LED strip with microcontroller and connections to install it inline to the rear brake lights. There's 6 sequence choices. When the sequence startup is done, it would shift to (default) running light mode (red LED's) with a brightness sweep when brakes are applied (sort of like an Audi). A button can be used…

ESP8266 Window Sensor with OTA and Deep Sleep

I was looking to boost my home security by adding window sensors. Something small and obscure so it would not stand out. I landed on this axGear sensor unit. It is small (70 mm x 20 mm). However, there was only one problem - it comes with proprietary software that I'm not sure I can trust. I also intended to integrate it with the ecosystem of devices I've created which I manage using Blynk. Of…

ESP8266 Fancy OTA Form

If you are a user of the ESP8266 OTA web update feature you're likely familiar with the above form when doing updates to your project over the air. Well, I'm going to show you how to spice up the form visual (hint - it's easy!). I just added this to my WIoT-2 Weather Project, which now makes updating a breeze. Background: There are a number of ways to do OTA updates on your ESP8266 (or…

WeatherCloud – IoT

So, my son's been bugging me to get him some of those LED strips for his room.  You know the ones that you see on Amazon with the remote controls.  I couldn't just go with status quo, so instead with a little grit and some free time I got on the LED cloud bandwagon and built him something a big puffy cloud with lights - what every teen wants right? ;-) What is it? It's…

COVID-19 Daily Stats on a Nextion HMI using ESP8266

While Covid-19 picks a fight with humanity, keeping busy and your mind clear is important for all of us. In addition to getting out on hikes and biking with the family, what better way to pass the time than to built IoT stuff! Since I had a new 7" Nextion HMI screen sitting around just waiting for a project, and had some vacation time, I decided to buffer up my skills and get to work.…

Basement Disco: NeoPixel Music Sync with MSGEQ7

I didn't have a lot of time in 2019 for projects as much of it was dedicated to finishing the basement. A year ago it was nothing more than concrete, storage and dustballs. Took the job on myself and did everything except hanging drywall and mudding (I hate that part). Best part of doing your own basement is you get to hack in all the bits and pieces necessary for future projects - like LED…

3D Print: Electronics Soldering 3rd Hand

After years using my reliable PanaVise, it was time to step it up with some extra help for soldering and electronics work.  I had this idea over a year ago, and pick-up some 3rd hand arms. They then sat on my   Now that the weather is cooling down, there's more time for hobbies.   That, and my eyes are not what they used to be, so this has become somewhat of a necessity.   Given MCUs…

USB Dial

This is another one of those "did it because I can" projects.  It's a USB dial that uses a Teensy Arduino unit at it's core and allows me to emulate my mouse.  I use TinkerCAD avidly to design my 3D printed models.   I wanted to have both this and my mouse at the same time.  The mouse would be used for some activities ( object selection/rotation/editing) while the dial would fill in to perform rotate/zoom in/out…

BTBox – LEGO Power Functions Bluetooth Controller

I've been on a bit of a LEGO Technic/Mindstorms hiatus for a while - ok, it's been 7 years!   I have an I've been spending much of my hobby time making my own DIY projects / IoT stuff all while mastering Arduino.   That changed a few weeks back when I came across THIS.  I've been thinking of getting an RC crawler for some time, but it struck me that I have 95% of the…
