The room employing this particular device is un-ish-viewable during the day light tho highly visible at night with interior lights, alight. Due to these parameters, the curtains automatically (photoresistor) open-close relative. Amended is a wifi (lower-case) channel to permit a voice activated command (url submit) to open-close the curtains, shd the moment arise, mmm-hmm.

Notation(s)
1. Timing is every thing .. preferring servos as opposed to steppers, this code requires a precise timing-per-rotation for the width of the curtain draw.
2. Patience .. just bcz it runs at 16mhz doesn't mean you shd. Averaging sensor reads .. delays .. give 'er a rest other wise the curtains will be flappin' back and forth like a chicken raised by geese tryin' to head south.

Notations
1. Prototype .. read the room.
2. NodeMCU (wifi) + HC-05 (not BLE) + TIP120 (relays) shd be a maker board. "VijeCU"?
3. Bcz the glow plugs are simply resistance wire coils, they gnd the circuit. MOSFET was attempted yet interference troubled the MCU+BT. For a more immediate impatient solution, we must use mechanical relays. Huge, bulky, module, relays...sigh.
4. WTH happen to those Radio Shack drawer 'mini' 5V relays?!
5. Isolate.

Trick for treat .. the illusion of proving you are alive .. and alive enough to even enjoy a treat.

This particular project is a carry over from a request to simply 3D print a heart for a 4th grade class demonstration -- and after negotiations negated instead reanimating a heart in a lightning storm .. uh, with an Arduino obviously .. we (me) pitched a pulse driven beating heart .. that in turn rewards your having proved to subsist, with a treat.

The IONYC makerspace neighboring Boys and Girls Club requested a hydroponics adaption from a broken pool table .. which meant employing children to hard labor .. as intended by Nature.

Dreary grey and brown (and tree countable) NYC collaborated with being below grade in a stone tomb of a building begged for more of an atmospheric eloquence-ish .. attempt; waterfalls (for oxygenation?) and LED status enclosure (for anxiety?!) .. bearing in mind that kids today are over-stimulated creatures demanding jangling keys to retain interest.


Ingredients
4" PVC
4" 90° PVC
22L Plastic Tub
Pool Table
Lever Switch
Float
5V Relay
LED Strip
Velcro
Florescent Fixture
Timer
Water Pump (min 1L/m)
Vinyl Tubing (0.5" and 0.25")
Threaded Barbed 0.25"
(4) Florescent Grow Lights
12oz Plastic Cups
Plant Nutrients
Clay Pellets

Notation(s)
1. Float valve built from a lever switch, stick and foam .. to a 5V relay .. flips the LED strip from blue to red .. alerting the user.
2. 3D printed 0.5 and 0.25 inch tube connections .. failed. Layered grain leaked no matter the tension of the pipe clamps.
3. Damn! .. -ed the tube every 10 cups to increase water level -- cut from excess piping.
4. Tattered soldering iron and /red/ (shd be white) plastic cups .. holes and hallucinations. Breathe with me-akhdfncsowpa;/.sa,
5. Themed blue and white relative to the BGC in question. Each over-paid unnecessary manager of this facility will elate to yet another assured tax-funded monthly income now thx in large part to my involuntary volunteering. Question your 'community centers' ..
6. Velcro lashing to secure and make removable the tubes.

Due to disinterest in updating scripting to retain precision measurements collaborated with more recent ease of data acquisition online .. we have shut down the OTC page (vijemiller.com/otc) after 10+ years. Links to the numerous categories of data aggregated will remain accessible on the OTC hold-page hosted locally. PHP and JS script will be made available both locally and on GitLab.

OTC remains our modern measure of time and will continue to improve relative to refinement of data. The Chromium extension displaying OTC day of year and year remains available here: otcext [download .zip]

Per request .. assisting in (doing) the construction of a display project for IONYC and the Boys and Girls Club of Astoria for Maker Faire NYC. The original proposal was for a Raspberry Pi 'weather station' .. but seeing as 'weather' is not abundant at a booth in Queens, we (me) decided to bring the weather to the weather station.

2. Wind is windy .. stop being so negative pressure!
3. Deadline was this project's undoing; shd have dome'd.
4. Due to circumstances .. SIAB will be left to a third party to operate (?!) at MFNY

When settling speakers in to place, you are idealizing that you will always sit dead center .. yet in our more lethargic reality, we lounge off-center. As consequence, you cease being the center of the speaker array .. until now ..

Code
https://hackaday.io/project/160842-center-surround-sound/log/152358-speaker-code-each

Notations
1. Intended to create an app with MIT App Inventor .. how-ever .. per the previous HaD FP (Voice Kitchen Faucet) .. it was decided to employ an alternative favored open source (-ish) voice command software http://voiceattack.com purely as demonstration.
2. Adding additional speakers merely requires copy-paste and if-statement modifications .. tho ideally a more advanced 'find' function upon installation would be coded.
3. Variances of % may depend on wattage (See #4)
4. Higher voltage systems would subsequently require HV digital potentiometers (AD7376)
5. Why is this .. not already a thing?!

Notations
1. Limited positions to averaging hot/cold/mix in deux bcz .. less is more.
Would diversify per #3.
2. #MakeArduinoCheapAgain
3. Recommend https://github.com/netlabtoolkit/VarSpeedServo as alternative to littering annoying for-statements .. unfortunately avr/interrupt.h is not ESP8266 compatible.
4. Shameless plug for https://www.theio.nyc/
5. Will you ever learn, me?! .. Shd you believe the arms are long enough .. add more.

Notation(s)

Lamps, alarm clocks, pencil sharpeners .. we leave some plugs in outlets for years unnoticed and hidden by furniture .. but over time these plugs can become loose and exposed .. leading to dangerous conditions.

Plugtite is your do-it-your-self-tho-Vije-did-it-for-you 3D printed solution to secure your plugs for life .. so that your home can safely burn down around you for a cadre of other reasons.


Notation(s)
1. Shout-out to https://www.theio.nyc/
2. Use a heated soldering iron shaft or stove to soften the legs for bending.
3. Dependent on print quality .. sanding the mounting feet may be required.
4. For narcissism's sake; the quality of the opening scene is rubbish due to now redundant voluntary third-world-prison filming conditions.
