Various ways of powering the MikroTik hAP

I have several MikroTik RB952Ui hAP AC Lite routers. They're located in closets, basements, attics, and on desktops. Each location results in different needs in terms of power.

Happily, the hAP AC Lite is quite flexible when it comes to power.

Here I document the three different ways I have powered my MikroTik AC Lite routers.

Power Solutions: Active PoE+ Splitter, Passive PoE Injector, and Standard wall adapter

Standard Power: MikroTik (or aftermarket) Wall Wart

The default way to power the AC Lite is by using its standard "barrel-style" power port, which is far more flexible than your typical router. The AC Lite accepts power between 10 and 24VDC. When using the MikroTik in a desktop configuration, I use the stock 24 volt MikroTik power adapter. The stock adapter output specifications are as follows:

24 VDC
1200 mA
2.1mm barrel
Center Positive

Passive Power-over-Ethernet solution: TP-Link Power Injector

Sometimes it is useful to power the router without the power adapter - like if you're placing the device in a place that's far from wall power. The AC Lite can accept Passive power over Ethernet. I'm not a huge fan of Passive PoE, but I appreciate that it is very affordable and has its uses. In my case, I use a TP-Link "TL-PoE2412G" Passive PoE power injector. These are super-affordable passive power injectors. When using this solution, I am usually powering a passive PoE device connected to port 5, which is the Lite's port that supports "PoE Passthrough".

Standards-Based Power-over-Ethernet solution: 802.3at/af PoE Splitter

Finally, it is completely reasonable to use standards-based PoE. Since the AC Lite does not natively support standards-based PoE, I use a common 12v 802.3af/at-based PoE splitter. These are a natural choice if you already have a standards-based PoE switch, such as this TP-Link PoE Switch.

I have my PoE switch powered by a UPS, so if power goes out, not only does my switch stay powered up, but all of my PoE gear keeps running too - including my hAP AC Lite.

Fixing a SodaStream Jet, part 1: Disassembly Guide

I've had my SodaStream Jet for years, and once in a while something has gone wrong. Disassembly is the first step to repair. Start with this article to see how to disassemble the SodaStream, and then once you have that down, scroll through my other articles to see how I repaired specfic SodaStream problems. SodaStream Jet Disassembly Guide Tools Required Flat head screwdriver Phillips head screwdriver 1. Remove the Carbonator. Duh. 2. Remove the black panel lever The front big black tilt lever needs to be removed first. Removing this panel is tricky, but it isn't impossible. Looking up at the bottom of the black panel, there are two tabs, one on the left and one on the right. These tabs fully secure the panel in place. The trick is to use a flat-head screwdriver under the plastic to gently lever the tabs out of the way. Note in the pictures how I approach these tabs with my screwdriver. I usually release the left side first, and then I release ...

Sodastream Carbonator Leakage, Usage, and Weight

SodaStream 60L "Carbonator" CO2 cylinders have a specific weight when empty, plus about 410 or so grams for the CO2 they should have when they're "full". A little while ago I went to buy a replacement Carbonator from my local hardware store. The dealer pulled a new Carbonator out of the box and sensed it was lighter than usual. He put the "light" Carbonator in the "empty" pile and sold me a different one. At that moment I concluded that it would be smart of me to weigh both new and empty SodaStream carbonators. Here are the results. Weighing a SodaStream Carbonator - for both Science and Consumer Protection. The dealer told me that sometimes the carbonators leak after they leave the SodaStream filling facility. That means there could be an opportunity for customers like me to get ripped off! The SodaStream cylinders I buy claim to have a net product weight of 410 grams - and that means that a full Soda Stream Carbonator shou...

Fixing a SodaStream Jet, Repair #2 - Broken Fill Button

My Soda Stream Jet's fill button broke, which means I can not longer carbonate water by pressing the pushbutton. This caused all sorts of grief in my household. Here is how I managed to repair my Jet to give it another 10 years of life (hopefully). First, a look at the button The fill button on the top of the SodaStream is actually a simple lever. Pressing down on the button moves a pin that does the actual work of pressing open the Carbonator's valve. Unfortunately, the axis point is fairly thin and can see a lot of stress. That's where my Soda Stream button cracked. [ I think the usage tip here is "don't over-press the button like a gorilla, it doesn't do anything but put high stress on the button."] Cracked levering point of the button The Pesky Lever Retaining Pin The Fix It was pretty easy for me to replace the button: Take off the back of the Soda Stream and remove the carbonator. Push out the the button lever's steel retaining pin. This takes qu...

Fixing my Wahl 9918 Groomsman Beard and Mustache Trimmer

Not everyone would bother repairing a $25 beard trimmer, but why not fix something for under $5 instead of spending another $25? My Wahl 9918 Groomsman Beard and Mustache Trimmer has admirably performed its beauty duty for many years, but the time came when the battery just wasn't holding a charge any more. Most people would just put the trimmer in the trash and buy a new one, but I figured I could repair my otherwise excellent Wahl and save some money. In fact, even high priced trimmer and rotary shaver brands, like Norelco and Remington, can be easily repaired using a process similar to the one I used to fix my Wahl. Read on to find out how. I opened up the Wahl by popping off the black plastic faceplate with a tiny flathead screwdriver, which revealed two screws. By removing the two screws I was able to easily open up the unit, revealing the guts of the device. Backplate off, Revealing the screws The internals are rather simple: a motor, a...

Robust Installation of an HDHomeRun Networked TV Tuner. 64 OTA channels!

I added an HDHomerun (HDHR) over-the-air (OTA) streaming box to my home network, bringing over-the-air broadcast TV to my computers, phones and tablets. The HDHR is a big upgrade from my previous setup: using a simple "window mount" antenna directly connected to my TV. A TV-attached antenna is good for watching some TV for free, but the HDHR offers so much more flexibility. Figure 0: HDHomeRun on my basement wall My original OTA TV setup was haphazard at best. It was finicky, ugly, and hard for other people at home to use. I would actually tape my antenna to a window whenever I wanted to watch OTA TV. Plus, it only worked on my TV and not with my other devices. I wanted a cleaner and more modern OTA setup. After looking at possibilities, I developed two goals: (1) bring my OTA TV into the modern Internet-connected era, and (2) set it up in a reliable and pretty way so that other family members wouldn't have to fool around with the antenna or anything else. With that,...

Verizon FiOS Electricity Use

My house has Verizon FiOS. Part of the FiOS installation included the mounting of a Verizon network backup battery unit in the basement. I asked myself "how much electricity does this box use?" Verizon FiOS: How much electricity does this cost me? So I plugged in my awesome Kill-A-Watt electricity usage meter to find out. My Kill-o-Watt watt meter reported that there was a 16 watt load on the circuit. And since Verizon's box is powered and plugged in 24 hours a day, 365 days a year, 16 watts would quickly add up to roughly 140 kilowatt hours per year: calculation: 16 watts x 8760 hours per year ÷ 1000 = 140.16 KWH/Year How much does 140 Kilowatt-hours cost in dollars and cents? Here's a table that shows how much that would cost per year based on recent residential electricity rates (source: DOE. State Electricity Profiles , 2006 Edition): State ¢/KWH ) $/Year Alabama 7.07 $9.91 Alaska 12.84 18.00 Arizona 8.24 11.55 ...
