Welcome to SWB Labs Displaying: Projects

One of the capabilities that is missing from the Amazon Echo is the ability to initiate spoken notifications even when the user hasn't addressed the Echo. Although Amazon will likely address this at some ... [More]

I noticed Rich Hawkes project on Hackaday for a WS2812 LED Tree and then reading comments further found a lasercut tree on Hackaday.io. The 7 rings were a little pricey but I found this 93 LED 5-ring set ... [More]

Quite a while back at one of our meetup groups one of the attendees wanted a way to monitor and document sound levels. We discussed a couple of approaches. One would be to use a microphone and monitor ... [More]

A couple of years back my daughter picked a science project that involved growing beans in varying magnetic fields. I thought it might be interesting to film the beans growing over a period of weeks. An ... [More]

The Amazon Echo can be extremely useful for triggering home automation. This ranges from custom homebrew devices to widely used devices like Insteon, Wink, etc. I happen to have a mixture of devices including ... [More]

When I asked my daughter what she wanted to be on Halloween she said she wanted to have an LED dress like Katy Perry. After some discussion, it seemed that we’d need a white dress that both diffused but ... [More]

When they were first introduced, I ordered a couple of Adafruit’s NeoPixel Rings that have 16 RGB LEDs in a 1.75″ diameter ring. I hadn’t decided exactly how I was going to use them but when I saw Phil ... [More]

At our daughter's school, all the 2nd graders put together a "state board" project. They are randomly assigned a state (in our daughter's case, Vermont) and the students work to put together a poster on ... [More]

I was inspired by Phil Burgess' great electronic mask project and knew I had to build one of my own.  The project is detailed in a combination of Adafruit tutorials on Animating Multiple LED Backpacks ... [More]

In my last post, I explored alarm monitoring using the Raspberry Pi and Arduino.  I thought I'd give the Electric Imp a try as well.  The Electric Imp is a WiFi module and Cortex-M3 processor built into ... [More]

I spotted a post by Lior Hass on Hackaday a little while back where he described his Alarmino project where his alarm system now connects with an Arduino and a custom board to simulate the phone line and interpret Contact-ID ... [More]

I was reading the April 2012 issue of Elektor and spotted an article by Ludovic Mézière on building a Thermometer using Giant Gottlieb® Displays.  I was really intrigued by his use of large mechanical ... [More]

A couple weeks back I got Romotive's Romo cell bot from a project I sponsored on Kickstarter. Cell bots use an onboard cellphone as their controller. As with other cell bots I've built, audio out is used ... [More]

I was playing a game of Connect4 with my daughter one day and it occurred to me there might be a nice way of sensing the moves in the physical game in order to introduce a computer player. Looking at the ... [More]

I happen to have some old 12 inch optical disks made of glass. So when I saw Terry and Adam Clarkson's ClockOS project on Kickstarter, I recognized the potential for an awesome clock!The ClockOS board ... [More]

I first saw the EggBot in action at MakerFaire and then waited to get in the queue to get one as Evil Mad Science prepared the kit for sale (just as I await their Digi-Comp II now).  As I was just getting ... [More]

The Secret Knock Gumball Machine is a project I built from the plans and instructions from Steve Hoefer's article in Make magazine (volume 25). Gumballs are dispensed only to those who use the secret knock ... [More]

I met the Macetech guys at Makerfaire 2009 in San Mateo and picked up a number of ShiftBrites.  This was my first of several multi-RGB LED projects.  I decided to array the 16 Shift Brites I had into a ... [More]

I thought I'd share another project from a few years back. Back in late 2007 I just finished up my third DARPA Grand Challenge Event (as an author of the pre-event simulator and real-time tracking software ... [More]

For Halloween 2009 my daughter got a butterfly princess costume. We thought it might be nice to light it up for safety and a nice effect. I thought of EL wire, which I'd just discovered and bought some ... [More]

After attending Adrian Crenshaw's talk at DefCon18 (slides, video) on using the Teensy as an exploit tool, I was inspired to give it a try.  I took a Teensy and added an RGB LED, photo sensor, DIP switches, ... [More]

In order to monitor our power consumption at our house, I set out to install a  TED (The Energy Detective) system.  The system monitors current flow into the house using inductive taps.  In our case, we ... [More]

I was intrigued by Mikal's article on his Reverse Geocache Puzzle Box from Make issue 25.  This is a box which will open only in a very specific place (as determined by its internal GPS system).  The LCD ... [More]

I've enjoyed assembling Gakken kits for some time. Ever since I had seen videos of Theo Jansen's work, I'd wanted to build models of his work.  Then I heard about the Gakken kit but it wasn't yet imported ... [More]

My daughter wanted to dress as Hermione Granger for the Halloween party at her school. We thought we'd jazz it up a bit with a special book she could hold -- one which might play the Harry Potter theme ... [More]

As part of a larger project I had a need for an inexpensive XY table.  I've built a couple of high-precision CNCs before but in this case I didn't need such high accuracy and was willing to make some compromises ... [More]
