Valentine’s Day gift for my wife:
A few weeks ago, much to the Wife Units glee, Costco had a deal on their entertainment centers with a built-in faux fireplace (it also has an electric heater that is of less consequence). While it’s a nice entertainment center, and the faux fireplace is convincing enough for our enjoyment, after having the unit for a couple of days, I did find a problem.
A bit back I opened my office mini fridge and found that it was warm. I checked all the obvious things: it was plugged in and getting power, and the thermostat was set correctly. Deeper diagnostics revealed that the thermostat was faulty. No matter the thermostat setting, it was not engaging to cool the fridge. If I bypassed the thermostat and manually (i.e. shorted the compressor leads) started the compressor the fridge cooled as it should.
I was unable to find an OEM replacement thermostat but figured I could make a replacement for less than a new fridge would cost.
I have a home “server room” that houses a couple of servers and other network hardware. In fact this site is being served to you from a VM running on a server sitting in that room.
If you’ve spent any time around servers (or any electronics for that matter) you know that they generate heat. I’ve recently consolidated a couple of physical servers by virtualizing them but the remaining physical servers, switch, cable modem, and UPS still generate about 2000 BTUs of heat. That’s about the same heat output as a small space heater.
The “server room” is a repurposed 30sq foot bathroom that is off of a main room (think of the typical master bedroom/bathroom setup). Managing the heat produced by the equipment has been an issue mostly solved by keeping the server room door open (to keep heat from building up) and running the existing bathroom exhaust fan.
My main issue with the current setup is having to keep the server room door open. This is especially an issue in the summer because the heat produced from the equipment is enough to overwhelm any cool air being pushed into the main room from the central AC. This makes both the server room and the main room perpetually hot. Also annoying is the noise from the equipment, and having to keep the door open prevents me from being able to doing anything to reduce dust incursion into the server room.
Note: since the original posting, I’ve added some updates (bottom of page).
A couple of years ago I came across some vintage light bulbs while perusing the aisles of Home Depot. Since then, I’ve been looking for a project to use them in. I thought that it would be cool to use one as an indicator light and started to form this picture in my head of what it would look like. I wasn’t sure what the bulb would be indicating, but the idea was now in my head and once I figured out what to use it for, I’d have to make it.
All that to say that this project was motivated by the need to make an indicator light using one of those vintage bulbs.
Harbor Freight sells these cheap incandescent headlamps for like $3.00. For what they cost they are not half bad. Still, I’d prefer an LED over the incandescent bulb.
I had one of these Harbor Freight headlamps (HFHL) and a broken1 LED flashlight. The flashlight used a 1 watt LED mounted to an aluminium PCB. The flashlight’s driver still worked too so I used it and the LED to convert the HFHL.
A while ago the Wife Unit™ found some decorative metal numbers in a sale bin at the store. We both thought that they’d make great address numbers for the house and since they were dirt cheap we, bought them.
It didn’t take long for me to decided that I wanted to do something more than just hang them on the house. The numbers are raised, sort of reverse embossed, so the edges are exposed. My thought was to back-light the numbers for a cool nighttime effect.
I needed to come up with a way to mount a 24″ TV in the ceiling. There was no way to mount the TV where it needed to go with more traditional/off the shelf mounts. Having thought on the issue a bit, going back an forth between ideas, I finally came up with a mount that used Kee Klamps.
