Things used in this project

Hardware components

Particle Photon

Adafruit Speaker - 3" Diameter - 4 Ohm 3 Watt

if they are out of stock just go to Amazon

Adafruit Mono 2.5W Class D Audio Amplifier - PAM8302

If they are out of stock just go to Amazon

Adafruit Tactile Button switch

These come in many different sizes and flavors. You could use a different style switch for this but these are very cheap. Also some Sparkfun kits come with a couple of these so check your inventory first.

Gikfun Mini Solder-able Breadboard Gold Plated Finish Proto Board PCB for Arduino Electronic Diy (Pack of 5PCS) GK1009

We used these instead of a breadboard as we wanted to make these as light weight and compact. This comes as a pack of 5.

Software apps and online services

Particle Build Web IDE

Particle CLI

Hand tools and fabrication machines

Weller WLC100 40-Watt Soldering Station

WYCTIN 60-40 Tin Lead Rosin Core Solder Wire for Electrical Soldering and DIY 0.0236 inches(0.6mm) 0.11lbs

Kester83-1000-0951 951 Soldering Flux Pen Low-Solids, No-Clean 10Ml

Capri wire strippers

If you're into electronics or messing with cars you'll want one of these! I prefer these over the standard 2 in 1 cutter/stripper.

Diagonal Cutters

Story

Hi and welcome to the story of talking walkies! (See what I did there) Anyway, this project was selected for our MEGR 3171 class and is a great way to get introduced into the IOT Photon world. Luckily we were able to follow an already built project write up from David Middlecamp that includes everything from list of items, diagrams and code. Hopefully we are able to add a little something whether its just tools or an STL for a case.

Now you and your buddies can talk to each other across campus. Texting and snap are a bit overrated now a days. Lead the revolution with one of these bad bois!

I did not come up with this myself so I will let you revert back to David's page for the insight to what is going on.

Code

Code for the walkie talkies

You'll want to use the Web IDE to write the code. When you go to "write" the code, there are 4 codes that will need to be copy and pasted into Web IDE. Select the firmware folder, then select, copy and paste the main.ino code. To do addtional subsets, select the little plus symbol to the right in Web IDE. You'll see 2 more pages are addded with cpp and h. Then just do the same for SimpleRingBuffer.cpp/h and SparkIntervalTimer.cpp/h Make sure both Photons have the code loaded and away you go!
