Wii Balance Board Smart Scale ( w/ ESP32 )

Wii Balance Board Smart Scale ( w/ ESP32 )

People have used Wii Balance Boards before as scales.  The projects I saw were typically paired with a phone or a Raspberry Pi via bluetooth and the data was handled by those devices.  I didn't want to go that route but instead wanted...

Nixie Clock #3

Nixie Clock #3

This is my 3rd Nixie clock.  I obtained some Burroughs B-5870ST tubes and wanted to make a clock with them.  These are awesome quality tubes made in England.  The mesh is super fine and the numbers are very well formed.  They are nice...

Wall Pluggable Nextion Screen with WiFi

Wall Pluggable Nextion Screen with WiFi

After the last screen experiment I wanted to try a Nextion screen.  These screens are somewhat interesting as you load the GUI onto the screen module itself and interact with the GUI objects programatically from your microcontroller...

Wall Pluggable LCD Touch Screen with WiFi

Wall Pluggable LCD Touch Screen with WiFi

This is primarily just an experiment with a LCD Touch screen that can be plugged directly into a wall socket.  This is using a cheapo touch screen with the ILI9341 display driver and XPT2046 touch driver.

Future iterations will involve...

RFID Door Access V2.0

RFID Door Access V2.0

I made this RFID door system over a year ago and it has performed flawlessly for over a year and still going.  It was the first time I made one of those things so now it's time to improve it a bit.  The improvements are mostly to do...

M2M : GSM/GPRS to WiFi Bridge

M2M : GSM/GPRS to WiFi Bridge

I wanted to expand some ideas about access control so the next step was to incorporate some devices that could be called with a cellphone to initiate some arbitrary action.  The unit thus needed some GSM and Wifi capability which was...

Nixie Clock

Over the years my girlfriend has handmade me some awesome and wonderful birthday cards.  Wanting to make a Nixie Clock and also wanting to handmake her something that (I think) is nice converges nicely in this project!

Hopefully it...

WiFi Enabled Button

WiFi Enabled Button

Some time ago I deployed a RFID access system that over time needed a way to arbitrarily open the door from within the office.  The way that made most sense to me to handle that was to make a button attached to an ESP8266 module and...

Nixies Part 1

Nixies Part 1

For some time I've been meaning to play with nixie tubes.  Recently I decided to do it and went out and bought a bunch of stuff to get going with it.

There's a LOT of people that have used these in various projects (mostly clocks it...

A6 GSM/GPRS Module (Send an SMS)

A6 GSM/GPRS Module (Send an SMS)

After figuring out that using a M590E module (see here) in North America was out of the question so I ordered some A6 modules and also a couple A6 dev boards to speed up testing.  The dev boards arrived first.

The dev board looks like...

M590E GSM Module

M590E GSM Module

These things are dirt cheap so I picked a few up awhile back and am now getting around to experimenting with them.  It should be pretty fun to control things via SMS or get notifications from a defice equipped with one of these.

ALIX 2D13 Router LCD

ALIX 2D13 from PC Engines are boards I have used for numerous years and have had nothing but good experiences with them.  Typically I used Voyage Linux and OpenWRT on them.  Recently I was thinking about a guest access point I needed to...

RFID Door Access

I had to put together one of these recently for a building and thought it would be interesting to see what I could come up with.

I'd bought a cheap RFID reader some time ago from Ebay or Amazon just to play around with and my first...

Cap Touch Light Switch (on/off)

Cap Touch Light Switch (on/off)

I Wanted to make a capacitive touch light switch (on/off) that would send singnals via WiFi to my automation system.  The assembly consisted of a PCB for the MPR121 chip,  an ESP8266 (on a NodeMCU dev board) and some LED's.  This would...
