Backup home internet

With new most asus routers you can use a feature called dual wan. I have the luxury of having a work provided cell phone I am using for this. Before having that I had a free service called freedompop.

Use cases (mainly mine):

  • Watching netflix withouth interuptions.
  • Backup internet for home security system.
  • Anything internet…

To start off we plugin a cell phone to the routers usb port.

I won’t be able to finish my wrist brace project for a while. These instructions are very rough because they’re not actually finished. 

Post in comments if anything needs clarification.

Scanning

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 316” Drill Bit
  • 14” 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. [Read More]

433mhz testing

I decided due to the lack of community support I am not going to make a Zigbee 433mhz chip instead I will continue my efforts with the WiFi esp8266. Now that I have the 433mhz working with the esp8266 I will be performing some distance testing with a few receivers I purchased and different antennas I have.
