my oofuri experience so far has been "damn abe i can't even think of a homosexual explanation for that, let alone a heterosexual one. you are insane." and then feeling the worms burrow into my frontal cortex about any two given characters on screen at a time.

pump malfunction causing high blood sugar for most of causing me to be depressed yesterday. tummy was nawt happy last night and this morning….now headache. can i just have like a good 24 hours maybe.

i hope i am not just an ao3 username to you but a gremlin hunched beneath what little daylight straggles through my bedroom window handwriting the next chapter of my WIP during a 12-hour power outage on a gloomy christmas eve eve so i'll have something to post before 2024

got a new cable for my ipod and charged it up to full and the battery has lasted like. two hours so far.

How do you achieve you distinctive style? Is it vector art?

Thanks for asking! So i draw with my finger on Sketchbook Autodesk on a laggy 5 year old phone (0: heres my process: i start with a 5000 x 5000 square canvas, mirror tool and a sketchy pencil, I sketch out the rough draft of a character until it looks about right.. Then i start the redraw process, I make it transparent, and start a new layer, I layer each shape like cutout construction paper.. I draw the outline of the torso in the color I want to use, fill it in, and then start a new layer, draw the outline of the legs, fill, new layer, arms, head, hair etc.. Then i go through with little details, separating lines, fur fluff, scales, face, etc.. So basically a lot of layering of solid color shapes on top of each other! Someday I will screen record a full piece when i can get around to it.. Hope this helps somehow !

Debunking the Myth of the 12-Hour Lithium Battery "Activation"

When it comes to lithium batteries, there's a longstanding myth that they need an initial "activation" process involving charging for over 12 hours, repeated three times. However, this claim is based on outdated practices, particularly those associated with nickel batteries like nickel-cadmium and nickel-hydrogen, which were popular over two decades ago. It's high time we set the record straight and understand the correct methods and precautions for the first three charges of lithium batteries.

The Dangers of Ultra-Long Charging and Full Discharge

Charging lithium-ion batteries excessively, particularly for extended durations, is unnecessary and can lead to severe damage. Ultra-long charging and complete discharge can result in overcharging and over-discharging, causing irreversible harm to the positive and negative electrodes of lithium-ion batteries.

At a molecular level, excessive discharge forces the release of an excessive number of lithium ions from the negative carbon, leading to the collapse of its layer structure. Conversely, overcharging crams too many lithium ions into the anode carbon structure, causing some to become permanently trapped. This is precisely why lithium-ion batteries are typically equipped with charge and discharge control circuits.

Correct Methods and Precautions for the First Three Charges

Contrary to the outdated belief of a 12-hour charging regimen, lithium batteries today come with built-in charging circuitry that safeguards against overcharging. There's no need to leave your battery plugged in for such extended periods. When a lithium battery is new, after prolonged periods of inactivity, or even after heavy usage, you can simply follow these guidelines:

Fully charge and discharge the battery once.

After this initial cycle, your battery is ready for regular use.

For long-term storage, charge the battery to around 40% or check the voltage of each cell (ideally, 3.83V per cell) before storing it.

If the battery remains unused for an extended period, it's advisable to perform a charge and discharge cycle once a month.

Understanding Charging Methods

Charging lithium batteries is generally straightforward, but safety during the charging process is of paramount importance. Here's a basic outline:

Charge with a stable current, typically ranging from 0.2C to 0.7C, depending on the manufacturer's recommendations.

Continue charging until each unit of the battery reaches 4.2V (volts per cell) and maintain this voltage until the charging current falls to about 10% of the initial value.

The precise peak charging voltage and the end current may vary slightly among different battery manufacturers.

Regardless of these specifics, a charging timer should always include a safety mechanism.When the battery reaches 4.2V per cell, it has only reached 40% to 70% of its full capacity.The charger should not immediately cut off power at this voltage; instead, it should continue charging until the current drops significantly, and then stop charging at a low current.

For those using standard chargers, it's important to note that even if a voltmeter indicates a voltage of 4.2V, the battery is not fully charged. At least 60% of its capacity remains unused. This underscores the importance of using a dedicated lithium charger with constant current and constant voltage charging capabilities.

In summary, forget about the outdated 12-hour charging myth for lithium batteries. Follow the manufacturer's guidelines, prioritize safety during the charging process, and you'll ensure the longevity and efficiency of your lithium-ion batteries.

my mom thought she was being nice getting me aaa when I bought my car.

she just got to experience it first hand with her own car.

"we'll have someone out there by 8:43pm"

it's 1 am and I JUST got a call back from a human (last three calls were automated) who informed me the car wont be collected until 8-10 am.

so yeah. probably won't be renewing that subscription.
