Flora + Fona SMSsenger Bag
Scroll text messages on your bag, jacket, or any other surface, using a Flex NeoPixel Matrix and Flora + Fona! Combining these two powerful boards can create the wearables projects of your dreams! This guide starts by covering the particulars of hooking Fona up to Flora including wiring and code modifications, so you can take most any Fona project and build it with Flora.
Before you begin, make sure to familiarize yourself with the following prerequisite guides:
Supplies
To build this project, you will need the following parts and tools:
- Flora microcontroller
- Fona cellular module (Fona 808 and 3G will also work) with SIM card
- GSM antenna
- Flexible 8×32 NeoPixel Matrix (dotstar matrices will work too with slight code and wiring adjustments)
- 2500mAh lipoly battery
- 26 gauge silicone-coated stranded wire in various colors
- soldering iron and tools
- E6000 adhesive
- Velcro tape
- Sewing machine (optional but convenient)
Mystical LED Halloween Hood
Create glowing eyes for your costume! This project is ideal for any character with glowing eyes, like the Black Mage from Final Fantasy, Jawa from Star Wars, or Orko from He-Man. Two NeoPixel Jewels can appear any color or animating pattern, and they are driven by a GEMMA microcontroller powered by a 500mAh lipoly battery in a 3D printed pocket.
Before you begin, check out these prerequisite guides:
- Introducing GEMMA or Introducing GEMMA M0
- NeoPixel Uberguide
- Adafruit’s Guide to Excellent Soldering
- Let’s put LEDs in Things

For this project, you will need:
- Two NeoPixel Jewels
- Adafruit GEMMA or GEMMA M0 microcontroller
- Silicone coated stranded wire (30awg recommended)
- Soldering tools and supplies
- Sewing pins
- Tailor’s chalk
- 19awg galvanized steel wire
- Coat fabric for hood/cape
- Translucent fabric for face panel
- Sewing machine
- Scissors
- Needle and thread
- SemiFlex 3D printing filament

How To Sew NeoPixels with Conductive Thread
What’s a wearable project without LEDs? Designed specifically for wearables, bright RGB LEDs are paired with a constant-current driver chip. The contacts are easily sewn with conductive thread. Use this guide to test your first pixel and start on a blinding wearables project with Circuit Playground Express, FLORA or GEMMA!
Each pixel draws as much as 60mA (all three RGB LEDs on for full brightness white). In theory, FLORA can drive up to 500 pixels at 30 FPS (above which it will run out of RAM). Circuit Playground Express can drive more than that. However, above about 20 pixels (and/or if the overall length of conductive thread exceeds ~6 feet/2 meters), the nontrivial resistance of the thread adds up and can affect the power supply. For large quantities of pixels over 20 or if you need to insulate your circuit, you should upgrade to silicone coated stranded core wire, which will provide better conductivity for the pixels – the current draw will add up fast!
Before you begin, familiarize yourself with the following tutorials:

Searching for a simple costume project to bring your Unikitty or Lady Rainicorn to the next level? 3D print a flexible unicorn horn and illuminate it from within with NeoPixels and a GEMMA M0, GEMMA v1 or GEMMA v2 based microcontroller. Or forget the electronics and use glow in the dark NinjaFlex filament for a green glow with no batteries required.

This is a pretty quick soldering project that is suitable for attentive beginners! Prerequisite guides:
- Introducing Gemma M0 or Introducing GEMMAÂ
- NeoPixel Uberguide
- 3D Printing with NinjaFlex
- Adafruit Guide to Excellent Soldering

For this project you will need:
- Ninjaflex filament in white, translucent, or glow-in-the-dark
- 2 NeoPixel Sticks
- The GEMMA M0 is recommended over the GEMMA v1 or GEMMA v2. Either will work.
- 500Ah lipoly battery and charger
- Silicone coated wire in three colors
- Grosgrain ribbon and hair elastic OR baseball cap
- Fiberfill (optional)
- Needle and thread
- Soldering tools and supplies
- 3D printer
- seam ripper
- scissors
- double-stick foam tape
- sewing machine (optional)

Roll-up Video Light
Using DotStar LED strips we can create a flexible, portable light source for video and photography. It can squish into small spaces, easily hang up on location, and it’s fun and simple to make.
Different lighting situations call for a different color temperature of light, so we’ll combine warm and cool white LED strips and program a Pro Trinket to adjust the light with a four-button membrane keypad.
We saw a crowdfunding campaign a while back for something similar, and when it was canceled we still wanted one. Now that we have these DotStar LED strips in the shop we can build it together.
Before you begin, read/watch the following guides:
To build this project, you will need:
- Pro Trinket 5V
- Adafruit DotStar LED strip in warm and cool white (1m each)
- Membrane keypad
- 4400mAh USB battery pack
- Silicone coated 26ga stranded wire in four colors
- Soldering iron and supplies
- Premium female jumper wires
- Heat shrink tubing
- Silicone adhesive such as Permatex 66B
- Durable fabric
- Velcro tape
- Sewing machine
- D-rings or clasps to make attachment points (optional)
- Scissors
- Needle & thread

Bowtie with LED Sequins
Bring some bling to your formalwear! Don’t be left out when your prom date shows up in her twinkling Sparkle Skirt, add some LEDs to your bow tie! This beginner project is a great way to get into e-textiles. No programming or soldering required, just a bit of stitching.
You don’t need much background to start this project, just check out the Conductive Thread guide for tips on working with this tricky textile.
For this project you will need:
- 20mm coin cell battery board with switch
- 2-4 LED sequins (such as white, blue, red, green, or pink)
- 2-ply conductive thread
- CR2032 coin cell battery
- sewing needle
