A/C Vent Hack for Cities That Shd Fall
Providing that this site caters to the hacking of items so as to improve upon -- and being that I currently temporarily reside in a place clustered with archaic dwellings, I thought it generous in passing to relate a means to resolve for an engineering issue many likely suffer from when living in elder metropolises.

Numerous residents are required to dangle a/c units from their windows this time of year and often times the misalignment of windows, bcz the buildings were designed and constructed by cretins, results in inefficient distribution of air.

Here, as follows, is a method to improve upon the efficiency of your air conditioning by employing nothing more than scrap cardboard, a ruler, pencil and tape.

Realize that shd some one come across this, recognize the opportunity and subsequently are able to increase the efficiency of their a/c unit, resource use may be ever so slightly reduced and the planet, saved...ish.

Bwahahahaha and ha.
[Sinistering Intensifies]

1. Arduino Uno
2. HiLetgo Pulse Sensor Module
3. 5V Relay
4. Heart (4$/eBay)
5. Blair Witch Project
6. 10K Pot
7. 1K Resistor
8. NPN Transistor

1. Opted to disregard specialized code/software for the reasons of code-illiteracy -- the contradiction being that the native code for the pulse sensor blinks an LED. Meh.

2. Bcz the sensor is placed on a finger with very little to ensure consistent application, the analog values varied giving irregular peak values. To adjust per each application, we (me) added a pot to adjust the peak triggering value (high).

3. The Blair Witch Project is best served when watched alone. To accompany another is to give an identifiable secured surrounding relieving the immersive stresses permitted by the film's atmosphere. It is a superb horror film you nay saying butt holes!

Never...never going to give you up.
This attempt, how ever, shd have been.

Original project had intention of dispensing compressed air in bursts to disrupt the flow...I uh, do/did not have access to such spare equipment. I welcome another with shop to give it a shot.

Special guest hallucinated appearance by @RealSexyCyborg. If (pause) only.

One animal (human) was harmed in the making of this film.

1. Arduino Uno
2. Rubber Ducky
3. Servo
4. Vinyl Tubing
5. Water Fountain Pump
6. Exposed 120 Volts
7. 40W 120V Light Bulb
8. Salted Water
9. String

1. Meh.

2. Minor adjustment to the servo delay would have drastically improved the flash rate -- how ever, timing (space use) and operational alterations tested one's patience beyond the threshold of interest (see Notation 3).

3. Moving on...
