Infinite, Free?, Small storage for electronics

Im a little dissapointed in myself for not thinking of it sooner. I tossed about 20 of these in the recycling bin before I realized I could reuse them myself.

Title is a little deceptive yes, but I still consider them free when you have a source. Baby formula containers!

When You can get yourself a source… well you have a source! They will feel endless and will just keep on comming. I have racked up quite a decent amount of them. I am able to use them for part storage, office supplies like rubber bands, resistors seperated in ziplocks and much much more.

To get started you first peel off the paper label.

Clean out the inside with a paper towel. Dont use water since these are made with cardboard.

Apply a label or sharpie, then stack them away.

You are probably wondering were to get these. Reach out to a pregnant friend or couple i’m sure they will bag them for you. The other method is do what I did…. Have a baby… jk haha. My wifes pregnancy was completly unrelated to this.

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.

3d printed wrist brace – WIP instructions

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.

Supplies/Tools needed:

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.
