Network cabinet

I built this cabinet to hide the wires near the network, phone, and TV jacks. I used IKEA "wood" cut into strips on a table saw. The cabinet door is also from IKEA, and matches the other furniture in the room. I made sure to have plenty of ventilation by leaving gaps at the top and bottom of the door as well as at the back. I measured the temperature inside, and it was just slightly above ambient.
This cabinet blocks the annoying light from the network equipment in case someone wants to sleep near it. It will also keep dust out.

Before organizing the wires

Building the cabinet was the easy part. The hard part was doing the cable management. There are 3 boxes, 3 AC adapters, a power strip, a phone splitter, 3 phone cords, 5 ethernet cables, and a coax cable. It took lots of Velcro straps to keep the cables tidy. It would be nice to have shorter ethernet cables that don't need to be looped.

Teabot Cord Replacement

When I first built my tea robot, it had an 18 inch long 14/3 SJT cord. I decided to replace it with a 5 1/2 ft 16/3 HSJO cord because the short cord annoyed me.

The old short cord

There are lots of types and sizes of cords that I have learned about. Here's a website I found that has a good guide to cord types:

The new longer cord

Several of the parts I have added to my tea robot recently have been recycled from a device I took apart. The large water tank, one of the water level sensors, tubing, and cord are all from a neighbor's broken Keurig that I wasn't able to repair. The problem with it wasn't electric or electronic- the pod chamber just wouldn't stay closed. Even if I had been able to fix it, it was annoying because it wasn't compatible with reusable pods.
One water level sensor turns the pump on when there's not enough water in the upper tank. I made a second water level sensor for the lower water tank out of metal skewers (since the probes needed to be food safe), separated by a piece of plastic to prevent short circuits. When the tea robot senses that the lower water tank is empty, it disables the pump and a pink LED lights up to let me know to refill it.

Pink LEDs are rare in most products, but they are becoming common in grow lights.
