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.…

3D Printed Diffused Case for NeoPixel Ring (12 LED)

Not being able to leave well enough alone, I'm toying with adding more show to my basement disco setup.  I decided to pick up a couple NeoPixel rings (12 LED version) and integrate them into the music-reactive mode.  These will be slotted in the open space at the bottom of the speakers near the sub port (see link below).   This was designed to fit for this NeoPixel Ring.  If you want to print some, download the…

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…

Review: LED Ring Magnifier PCB Bench Vise with Helping Hands

3rd hand tools are a must-have when working with soldering. You need something to hold the PCB, the solder, and the soldering iron. Basically any project where you need a (wait for ) 3rd hand! A magnifying glass is also helpful for those with aging eyes. My friends at sent my this to check out and I have to say I'm impressed.

Review: Adjustable 30V/10A DC Power Supply

I recently received the LongWei 30V/10A (Model: LW-K2010D) power supply from to review. Full disclosure - it was sent to free for this review. That said, I'm transparent about my views on things and don't sugarcoat. The below review is my first impression of this unit doing some basic validation of it's functions. In the coming months I'll drop back in and update as I get more experience with this PS. The review is broken…

3D Printed Banana Jack Inset Speaker Plate

In Nov 2018 I took on the adventure of finishing my own basement.  I'm now at the point where I'm wiring my AV system up and focused on the audio part.  When looking to find banana jack wall plates for the speaker connectors, I was surprised to see that most are flush mount with the banana jacks sticking out.  You can find some that are wall mounted, but they can be pricey and don't fit…

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…

3D Printer Raspberry Pi stand & case for OctoPrint Rig

Now that I'm done adding a TFT to my OctoPrint Pi rig, next step was to make a cradle mount for the LulzBot Mini.  I also integrated a power switch into the build.   The cradle is a remix from the Adafruit guide, while the shell are direct prints.  STL files for the remixed cradle are here.  The power switch holder is printed separately then glued using Goop (best glue ever!).

How To: TFT LCD with TouchUI on Raspberry Pi OctoPi Rig

I recently ventured into adding a " TFT to my LulzBot Mini.  I already have OctoPrint running, but there are times (usually during filament failure events) I need to directly control the printer (heat the filament, move axis motors etc).  After 3 painful days of messing around with different tutorials, I finally figured it out and it works dammit!  I haven't found a single source that has all steps in one place, so I decided to…
