Reusing Tile as car tracker.

Ever since I switched to Samsung smart things I purchased presence sensors and had no more use for my tiles after the batteries died. I retired them to a box for a long time. Today I figured out a neat project for the tile. I am going to turn it into a tracker for my cars. This is not real time tracking but can help find your car in larger cities.

3d Printer Filament box done quick

Keep your filament dry! Filament used for 3d printers will absorb moisture from the air and damp filament prints very poorly. With Buffalo’s high humidity and our printer being run in a basement, we absolutely need a dry box for our spools. We ordered parts ahead of time, slammed this box together in an afternoon, and then baked our spools to rid them of moisture.

We’re using a large plastic bin for storage, teflon tubing to run from the box to the printer, and pneumatic connectors to ensure the filament feeds smoothly into the tubing without snagging. A large pack of silica gel keeps the box dry over time. Our basement also has an additional air dehumidifier that we keep at 50% to prevent mold growing on our wood/mdf surfaces.

Supplies:

  • Sterilite Air Tight Bin, fits about 8-10 reels. (Amazon)
  • 5-10 Meters of PTFE Teflon Tube OD 4mm ID 2mm (Amazon)
  • M5 Lock Nuts, 1 per reel (Amazon)
  • 5mm Male Thread 4mm Push in Joint Pneumatic Connector, 2x per reel (Amazon)
  • Scrap Wood Strip
  • 608ZZ Bearings, 4x per reel (Amazon)
  • DRY&DRY Silica Gel Desiccant Packet, Rechargeable (Amazon)

Tools:

  • Power Drill
  • 5mm or 3/16″ Drill Bit
  • 1/4″ Drill bit or larger
  • Sander/Sandpaper (optional)
  • Rubber Mallet, Optional but makes it easier to fit bearings
  • Oven

433MHZ More Things for Smart Things

Finally – off the breadboard and into a working environment. It’s currently working for 433mhz sensors, I will possibly be adding more frequencies later. For now I will continue refining the code to release it on github.

 

Day 1:

A few issues. I accidentally flipped the polarities on the siren. I will eventually implement a 12v regulator to up the voltage for the siren for the full 120db power.

 

Day 2:

My cat set off one of the motion sensors at 6AM, activating the siren. I need to adjust the sensitivity or get pet-friendly motion sensors.

Complete Smart Home Setup

 

I wanted to talk about my smart home setup from the ground up. I have many articles describing my setup in pieces but not everyone gets an entire overview of everything I have setup here. I don’t have a mansion or anything fancy like built in sprinkler/irrigation, so this will be more catered to your average city home.

 

The Assistant:

Google Home and/or Mini manage my random routines that aren’t part of a automation rule. Going to the basement to do laundry, or going to sleep at random times. I can just send a command and google home will handle it. Link your SmartThings account and Google Home together for best results. Give all your devices aliases to make it easier to command via Google. I want one located in every central room of the house, Kitchen, Living room, Master Bedroom.

Control Center:

What controls my entire setup and why I chose this hub vs others. My only hub is a Samsung SmartThings hub. This manages just about everything in my home minus the security cameras. I did heavy research on many hubs including Wink, IOT (hub-less), and Phillips hue. Why SmartThings?
