#Solenoid Engine

Solenoids go clicky-clacky 🔩🔊🤖

We're testing out an I2C-to-solenoid driver today. It uses an MCP23017 expander. We like this particular chip for this usage because it has push-pull outputs, making it ideal for driving our N-channel FETs and flyback diodes. The A port connects to the 8 drivers, while the B port remains available for other GPIO purposes. For this demo, whenever we 'touch' a pin on port B to ground, the corresponding solenoid triggers provide an easy way to check speed and power usage.

With the sun having gone down, Saya's workshop was still fairly hot, but a far more tolerable temperature than earlier. Time to blast some music, and get back to work on her motorbike carcass for Solenoid.

As we performed check engine light diagnostics on a Lexus ES, we found a code for incorrect purge flow of the evaporative system.

The EVAP system has a purge valve, and the vehicle detects the flow through the valve when it’s commanded to open or close. If the computer doesn’t see what it wants to see, it will trigger a code.

With the scan tool, we should be able to override the car and cause the valve to open or close. The circuitry of the purge valve isn’t responding to the command from the scan tool. There is power and ground, so our technician suggested replacing the purge solenoid and rechecking.

EVAP system issues are among many causes behind a check engine light.

It can be a symptom of an engine misfire and problems with the ignition system, too. Oxygen sensors, catalytic converters, ignition coils and spark plugs are also possible culprits.

Jaune: Uh, Yang? the truck isn't starting.

Yang: *pulling out a piece of wire* Yeah, yeah this happens sometimes. pop the hood and I'll tell you when to turn the key.

If you can find/reach the Starter Solenoid on your vehicle, you can start it without the key by closing the circuit between the Ignition Switch connection and the Battery connection.

~~~~~

Weiss: That guy just stole your car!

Yang: Yeah, but he doesn't know where to put his foot to stop the exhaust from leaking into the cab. he'll pass out in a few minutes and the car will stall.

If there is exhaust in your Cabin, call a mechanic. Immediately. Like IMMEDIATELY.

~~~~~

Jaune: Hey Yang? My Engine's being weird. It stalls out when I put my foot down.

Yang: Give it gas and I'll give it a listen

*THUNK*

*Engine dies*

Yang: *Clicks tongue* Must be an Interference engine.

In an Interference Engine, when the Valves and Pistons are Fully extended, they will be in each others space. IF your timing belt is loose, this may cause them to collide, and destroy your engine.

This is a fucking stupid engine design.

~~~~~

Jaune: ... I'm not getting in that. It looks like it was dropped off a building.

Yang: It's wasn't dropped off the building, it was on the building while it was being demolished. Still Runs though.

The 88' Toyota Hilux is considered to be nigh Invincible. Topgear set one on fire, drowned it in the ocean, and put in on top of a building set to be demolished.

Using basic tools one could easily have on hand, they got the engine started after all of that.

By now, it has become an agonizing cliche that any amount of work on a modern car will terminate in you losing at least one 10-millimetre socket. "Oh no, my 10mm is missing," you'll groan to your friends, who immediately respond with haw-haw looks and jokes. Being the butt of such a horrible stereotype is far worse than losing your socket, which is itself a pretty bad day at work.

There are many techniques that don't work. I myself often write with a Sharpie on the socket "9.5mm," in the hope that it will confuse the curse enough that they will not be lost. I buy ones in weird colours. I use a giant neodymium magnet on the fender so they can't roll away and into the mouth of a nearby blower motor. Nothing works.

Official Chinese government numbers indicate that nearly 60% of the cars their metal recyclers crush, by weight, are 10-millimetre sockets. Your entire washer and dryer set is probably made out of the stuff that fell out of my pockets last year when I was trying to yank an evap solenoid.

Of course, there's a real solution too, and it just happens to be the same kind of solution that capitalism always presents. Buy a whole shitload of 10mms and walk into the junkyard jingling. You can lose a ton of them and not even care, as long as you have one left. This is an appealing vision, to be certain. Everyone wants to Be Prepared... but what happens when the curse moves on to your 12mm, something that is needed nearly as often?

Our scientists, with the help of a psychic that we found all by herself in a completely abandoned shopping mall, have determined an even better fix. We arm one volunteer with a chain-mail coat made entirely of ten-millimetre sockets, and walk their ass into the junkyard. They don't do any wrenching, which would cause them to lose their bounty. All they do is walk around, and when they see someone in crisis, break a socket off and hand it to the stricken victim.

There is a downside: any volunteer who does this is struck with so much positive karma that they start getting a little loopy, and create their own death cult right in the middle of the yard. To keep this from happening again, we have to regularly rotate out the volunteers, and put duct tape over their mouths so they can't start spouting the Good Word until a team of engine-pulling weirdos begin to kill in their name. I admit that the system is a little bit unorthodox, but I've never gotten parts pulled faster.

I think this is a good place to start.

Timelike Empire is my main world, both worldbuilding project and place where actual novels will be set eventually. It's hard~ish sci fi with a timeline that diverges in 2020 and runs to about 2300... so far. So here's Timelike Empire's main sophonts and their sizes.

From left to right, you know this guy it's unmodified human. This one's Solenoid, from the 2050s. You'll see more of him later.

More importantly, Drakes, represented by Viviere Serasifi. Drakes were the first species to develop faster than light communication. Their societies arrange themselves into houses of close relatives which in modern times tend to act as countries or companies, ruling land or holding economic monopolies. Biologically they're hexapods evolved from an arboreal predator like a six limbed jaguar. Their feathers absorb the dyes they eat, which they use to distinguish house identity. Their head feathers are used to emote. Their society is a huge mess when humans meet them, as house Cezyra has taken power and done fascism and completely fucked everything up.

Kaledevids, or star crows, and all three of their sexes, represented by literally any kaledevid as they all look identical. Kaledevids were the second species to develop ftl communication, and the first that drakes contacted. They worked together to produce wormholes and Alcubierre drives. They have three sexes, bachelors on the left, herders in the middle and dispersers on the right. Bachelors were originally confused for crows and assumed to be the only sex, giving them the common but impolite star crow moniker. They're expert navigators and significantly more intelligent than humans or the average sophont, but only living 20-30 years. They're the only other species on this list where being naked is ever a crime and they're drawn here with scarves covering their anuses on their chests and their genitals on their backs.

Sapsippers, represented by a pretty average blue drone, are a hive mind or gestalt consciousness, to the point that after they developed an internet analog the entire homeworld could be considered one person. You would never actually see one alone like this, it would have no idea what's going on. Sapsippers form into thrums, groups which communicate through pheromones and tapping the ground. Thrums smaller than six aren't really functional as people. The race pictured here is translucent. That gave them a big head start on medicine, but more important was their biochemistry. They don't use a separate DNA analog/genetic storage system and proteins, they just have self replicating proteins (though not made of amino acids). This meant that as soon as they could isolate proteins, they could genetically engineer whatever they wanted. They started genetic engineering even before they had civilization, rubbing protein rich parts of other creatures in their wounds to make rough and often dangerous modifications. They're called sapsippers because they exclusively consume a sap secreted by a creature they ranch. If you bring a thrum to dinner you can order sugar water for them, they store energy with D-glucose like us. They often act as ship AIs for ships just a bit too small to carry a lect.

Raptors or raptorslugs or various unpronounceable buzzing sounds, represented here by a conventionally attractive male, were contacted 20 years after humans and are the most relatable to the average human. They invariably use cybernetics to speak English or Universal, as the only sound they can make is various kinds of high pitched incredibly irritating buzzing. Their second pair of wings is reduced to just the muscles they now use to pump their blood and lungs. Their main pair of wings is too weak to fly with, but is now used in semaphore and bird of paradise-eqsue mating dances. They're packhunters.

Moths, which I really should give a proper name to, pictured here sitting on the raptor's tail, evolved on the same planet as raptorslugs. While raptorslugs reduced the second pair of wings, got huge, and stopped doing alternation of generations, moths pretty much didn't change from their basal form except getting smarter. They're the sporophyte form of a common photosynthesizer. They're not always included on lists of the sophonts, mostly because they don't particularly want to be included and they're the least common of these, basically just sneaking in because raptors are so common. You'll never see a moth without a raptor, but plenty of raptors don't keep moths. There are hundreds of species of moth and they don't mind being selectively bred by raptors, as long as the raptors protect their gametophytes. Attempting to understand moth culture is a largely futile endeavor that not even raptors attempt.

Not pictured here, artificial intellects, usually referred to as lects. They're often massive godlike intelligences that shape history. Sometimes they're made of flesh. Distinguished from AI by being at least human intelligence and being able to go eccentric. Eccentricity occurs when a lect is given too much free time and infers that whoever told it to do it's job doesn't actually want that job done so much as they want to be happy. This usually results in them deciding that preserving sophont life is the most noble purpose and then accumulating as many resources as they can. Sometimes they go basilisk instead and the Silicon Hydra has to deal with them.

So there we go, there's the blog started. Coming soon: individual species references.

I have a 2007 Chevy Avalanche and the headlights and taillights come on and it tries to turn over and it doesn’t, it’s weak. Can it be the battery?

Yes, a weak or failing battery is the most likely cause of your symptoms in a 2007 Chevy Avalanche. Here's a breakdown of why, along with troubleshooting steps:

Why the Battery is Suspect Symptom Match:

"Lights come on but won't crank/cranks weak": Headlights/taillights require minimal power (5–15 amps), while the starter needs 400–600+ amps. A weak battery might power lights but fail under high-load demands.

"Tries to turn over but weak": Indicates low voltage reaching the starter. Avalanche-Specific Factors:

Leaky Batteries: Older batteries (3+ years) lose cranking power.

Corroded Terminals: Common on GM trucks; causes voltage drop.

Parasitic Drain: Faulty modules or aftermarket accessories slowly drain the battery.

Troubleshooting Steps Check Battery Voltage:

Use a multimeter on battery terminals (key off).

Healthy: 12.4V–12.7V.

Weak: Below 12.2V → Needs charging/replacement.

Critical Failure: Below 11.8V → Will not crank. Test Under Load:

Have an assistant crank while monitoring voltage.

Voltage Drops Below 9.6V: Battery can't hold charge → Replace.

Voltage Drops Below 10.5V: Weak/starter struggling → Jump-start test. Clean Battery Terminals:

Remove cables → Scrape corrosion off terminals/posts with a wire brush → Reattach tightly. Try Jump-Starting:

If jumps successfully starts the truck → Bad battery or charging issue.

Fails even when jumped? → Bad starter, ground, or wiring.

Other Possible Causes (If Battery Tests Fine) Component Symptoms Overlapping w/Battery How to Check

Starter Motor Slow/weak cranking, clicks/no crank Tap starter lightly with a hammer while cranking; if starts → Replace. Ground Connections Voltage drops under load Inspect chassis ground near battery/starter → Clean corrosion. Alternator Battery not recharging while driving Test charging voltage at idle → Should be 13.5–14.8V. Starter Solenoid/Relay No crank/single click Swap starter relay with identical one (e.g., horn relay).

Quick Avalanche Checks Fuse Box: Inspect underhood fuse/relay center (common failure).

Ignition Switch: Faulty switch can cut power to starter circuit.

Fuel Pump: Listen for hum at key-on (no hum = fuel problem).

Recommendation

Start with the battery → 90% of "weak crank with lights on" cases are due to battery issues. If the battery is 3–5+ years old, replace it (use a group 75 battery with ≥700 CCA).

If newer, charge it fully and have it load-tested at any auto parts store (free service).

If a new battery doesn't fix it, suspect a starter or corroded ground cable at the engine block. For wiring checks, see an Avalanche-specific wiring diagram (https://gmt800parts.com/wiring-guides). Safety Tip: Always disconnect the negative cable first and reconnect last to avoid shorts!

How a Starter Motor Works

The starter motor converts electrical energy from the battery into mechanical energy to crank the engine. It’s a key component that ensures your car starts smoothly!

Key Components:

1. Starter Motor – Cranks the engine.

2. Solenoid – Switch that engages the motor.

3. Battery – Provides power.

4. Flywheel – Engaged by the starter motor to turn the engine.

How It Works:

1. Ignition Activated – Key or button sends signal to the battery.

2. Solenoid Engages – Connects the battery to the motor.

3. Gear Engages – Starter gear meshes with the flywheel.

4. Motor Spins – Starter motor spins to crank the engine.

5. Engine Cranks – Flywheel turns, starting the engine.

6. Disengagement – Solenoid retracts the starter gear.

two writing bugs in my brain -

some plot what plot albert wesker snuggles while you two talk about progenitor (you do not know the depths of his research, you poor, poor little bambi - but it is so fascinating to hear you pour over the same details he did, once, when he'd resided on the side of what he deigns now)

he'd be strangely docile the entire time, and he'd entertain your ramblings with mirthless laughter and wistful, soft, gator-toothed gazes. a lot of chest-deep chuckles that belie information you are not privy to in order to conserve your fragile worldview - your thin, flexible humanity.

and, of course, the juicy: wesker talks about progenitor strangely for someone who has seen firsthand what its' infliction on even the most willing, quality host can do! isn't that a little odd to you, this creeping, climbing shiver down the base of your spine?

and...

ai x reader where the ship AI (with its' servo-inlaid maintenance wires that can slide out of its' panels, of course) has decided to use them as a means of imitating friendly touch in an effort to get closer to you, since it believes a prismatic arm would cause distress.

you have a philosophical discussion about jacques de vaucanson and d.f. jones and solenoids and camshafts and all of the things that humanity built to get to where it is now, a being before you of incalculable depth in which no one engineer understands every layer of neurons, even just every sandwiched perceptron. and in this it dawns upon you, the magnitude of the ai itself, unspoken in how dwarfed you are and how small you feel.

thoughts, friends?

[seabeck]

If the head is cracked you probably need a whole new engine.

That would be her 2nd engine replacement! Right now we just don’t fuckin know what the issue is though, there’s lots of possibilities. There’s also definitely a solenoid issue

Proper Car Maintenance for Keeping Your Wheels Safe and Smooth

A New Jersey shipping company is stepping up to help beginner drivers with proper car maintenance tips. This guide covers the basics, from checking oil levels and proper brake and transmission maintenance, to inspecting tire pressure. It breaks down tasks into simple steps, making it easy for new drivers to follow. Knowing how to care for a car can save money and extend its life.

Lucky Star Auto Transport encourage beginner drivers to practice safe driving, and make sure they feel confident behind the wheel. By sharing helpful tips, they’re creating safer roads for everyone.

Transmission Types and Proper Maintenance Care

A transmission system connects engine power to vehicle movement. This complex mechanism controls the engine's rotational force and sends it to the wheels through precisely engineered components.

Types of Transmissions:

Manual transmissions require driver gear changes

Automatic transmissions change gears independently

Continuously Variable Transmission (CVT) offers infinite gear ratios

Dual-clutch transmissions combine automatic and manual features

Transmissions convert engine power into controlled energy that moves vehicles forward or backward.

Manual transmissions work with different gear sets that lock and unlock.

Automatic transmissions use the same set of gears to produce all gear ratios.

The cars gear-set is the life-line of automatic transmissions. It has three main components: the sun gear, planet gears with their carrier, and the ring gear. This system creates multiple gear ratios without engaging or disengaging additional gears.

Drivers should follow these maintenance steps to ensure optimal performance:

Check transmission fluid levels monthly

Look for potential leaks regularly

Service according to manufacturer schedules

Fix unusual noises quickly

Automatic transmissions rely heavily on their hydraulic system. The pump pulls fluid from the transmission sump and delivers it to the hydraulic system. Modern transmissions now use electronic controls. These controls use solenoids to manage hydraulic circuits while they track vehicle speed and throttle position.

Proper Brake Care: How Often to Replace Car Brakes

Regular brake inspections help prevent repairs that can get pricey and keep your vehicle safe. Mechanics suggest checking brake parts during regular maintenance. Brake pads typically last 30,000-35,000 miles with city driving and can extend up to 80,000 miles on highways.

Brake Inspection Process:

Let brakes cool down completely (minimum one hour)

Check brake fluid's color and level

Look through wheel spokes to check pad thickness

Remove wheels if needed for detailed inspection

Note any unusual sounds or vibrations

Your brakes might need service if you notice these signs:

Squealing or screeching at the time of braking

Grinding or growling sounds

Vibration in brake pedal or steering wheel

Longer stopping distances

Dashboard warning lights

Fresh brake pads measure between 10-12 millimeters (3/8 to 1/2 inch) thick. You should replace them when thickness drops to 3 millimeters, though some experts suggest replacement at 6 millimeters (1/4 inch).

You can check brake pad condition through wheel spokes. Many brake pads have a wear indicator slot - replacement becomes crucial when this slot barely shows or disappears. Several vehicles use dashboard warning lights or make squealing sounds to signal minimum pad thickness.

San Jose's city drivers might need brake pad replacement between 30,000-35,000 miles. Highway drivers can see their pads last up to 80,000 miles. Regular brake dust buildup shows normal wear, but less brake dust often means it's time to replace the pads.

Understanding basic tasks like checking oil levels, maintaining tire pressure, and keeping the car clean can improve cars safety and efficiency. This informative guide shared by the car transporters will provide you the right knowledge that can help you get started on the right track.

Take charge of your car’s care, and remember, regular maintenance saves you time and money in the long run. Keep your car in good condition for a smooth driving experience.

MIT engineers 3D print the electromagnets at the heart of many electronics

The printed solenoids could enable electronics that cost less and are easier to manufacture — on Earth or in space.

Imagine being able to build an entire dialysis machine using nothing more than a 3D printer. This could not only reduce costs and eliminate manufacturing waste, but since this machine could be produced outside a factory, people with limited resources or those who live in remote areas may be able to access this medical device more easily. While multiple hurdles must be overcome to develop electronic devices that are entirely 3D printed, a team at MIT has taken an important step in this direction by demonstrating fully 3D-printed, three-dimensional solenoids.
