Have you got any recs or a reading guide for steel ?
lornahs's guide for him & his dcuguide chronology collect most of his appearances. and i'm still not quite finished making my way through post-crisis superman comics, so if anyone with more expertise would like to add on, please do, but so far, these are my personal favorite recs for him:
The Death & Return of Superman
Steel (1994) (i love this book, but it is violently 90s in a way that definitely won't be to everyone's tastes. might recommend skipping it at first and then coming back later when you're already invested in the character)
the Trial of Superman arc:
Superman (1987) #106
Adventures of Superman #529
Outsiders (1991) #24
Action Comics #716
Superman: The Man of Steel #51
Superman (1987) #107
Steel (1994) #22
Adventures of Superman #530
Superman: The Man of Tomorrow #3
Action Comics #717
Superman: The Man of Steel #52
Superman (1987) #108
Adventures of Superman #531
Steel (1994) #23
Showcase '96 #1 - 2
The Millennium Giants
JLA Secret Files #2
he becomes a member of the justice league and is in JLA (1997) #19 - 41, but he's mostly just kinda... there. it's been a while since i read this book, so if anyone's got a fresher memory, please correct me if i'm wrong, but i don't remember him ever getting much of a focus in this book. it's fun to see him in the justice league for sure, and i do recommend reading it, but i can't say i really consider it essential reading for him specifically
Team Superman Secret Files & Origins
Superman: The Man of Steel #95 - 97
Superman: The Man of Steel #98 (part of the Superman Y2K arc)
Metropolis Secret Files & Origins
Superman: The Man of Steel #99 - 101
the Critical Condition arc:
Superman (1987) #158
Adventures of Superman #580
Superman: The Man of Steel #102
Action Comics #767
Superman: Emperor Joker
Superman: The Man of Steel #106 - 110, #112, #114
Our Worlds at War was also a pretty important event for him, but i really can't justify recommending that you read the whole massive thing if you're only interested in him. he only shows up in a few issues (which may be a little confusing without the context of what's happening in the entire event, but it's fine):
Action Comics #594
Superman: The Man of Steel #116 - 117
Superman: The Man of Steel #118, #120, #122 - 125
Superman: The Man of Steel #130, #131 (part of the Ending Battle arc)
Superman: The Man of Steel
Superman vs Darkseid: Apokolips Now!
the Strange New Visitor arc:
Action Comics #811
Adventures of Superman #624
Superman (1987) #201
he featured fairly often in in 52 & Infinity Inc (2007), but i haven't actually gotten around to reading either one of those yet beyond skimming a few random issues, so i can't really give any specific recs there
Superman #685 - 687, #689 - 690, #695 (part of the New Krypton Saga)
Superman: War of the Supermen (also part of New Krypton)
Reign of the Doomsdays
aaaand that brings us to the end of the preboot universe. i think he was a fairly major player in the n52 superman comics, but i haven't gotten around to them, either. the only post-reboot comic i can really recommend (and i do strongly recommend it because it's an all time fave for me) is Superwoman (2016)
beyond that, i believe he's a semi-regularly occurring character in the current superman titles & that there's a Steelworks book out there somewhere. but i've kinda lost interest in current comics for the time being, so that's all i can really say about that!
hope this helps & happy reading 💕

Programmable Logic Controllers By Dag H. Hanssen (ebook)
Programmable Logic Controllers By Dag H. Hanssen (ebook)
Widely used across industrial and manufacturing automation, Programmable Logic Controllers (PLCs) perform a broad range of electromechanical tasks with multiple input and output arrangements, designed specifically to cope in severe environmental conditions such as automotive and chemical plants. Programmable Logic Controllers: A Practical Approach using CoDeSys is a hands-on guide to rapidly gain proficiency in the development and operation of PLCs based on the IEC 61131-3 standard. CoDeSys, which is widely used in industrial design automation projects, the author takes a highly practical approach to PLC design using real-world examples. The design tool, CoDeSys, also features a built in simulator/soft PLC enabling the reader to undertake exercises and test the examples.
Introduces to programming techniques using IEC 61131-3 guidelines in the five PLC-recognised programming languages. Focuses on a methodical approach to programming, based on Boolean algebra, flowcharts, sequence diagrams and state-diagrams. Contains a useful methodology to solve problems, develop a structured code and document the programming code. Covers I/O like typical sensors, signals, signal formats, noise and cabling. Features Power Point slides covering all topics, example programs and solutions to end-of-chapter exercises via companion website. No prior knowledge of programming PLCs is assumed making this text ideally suited to electronics engineering students pursuing a career in electronic design automation. Experienced PLC users in all fields of manufacturing will discover new possibilities and gain useful tips for more efficient and structured programming.
These conventional panels are built up depending on the logic to be implemented after the mill builder provides the overall operational method which is elaborated further by the electrical supplier as per the actual implementation. While the functionality of the mill interlock panel is similar in the PLC panels, the concept defining the number of inputs and outputs came into the use with the implementation with PLC-s. As compared to the central relay and interlock panels or mill interlock panels , the modern day PLC based interlock panels are able to handle much more of functionalities as explained under III . Since the PLC-s themselves are micro- processor or controller based they have the same working architecture like the standard computer architecture with the following elements.
The inputs and the outputs form the bulk of the hardware depending on the plant requirement and capacity. While the PLC CPU, instruction sets, software, memory, communication and other capabilities . Apart from the functionalities , the PLC type is primarily decided based on the number and the type of inputs and outputs. The defining of the inputs and the outputs got into the use with the use of PLC-s for the control and interlock functions. This is because in the PLC panels the status of the inputs or outputs ( called input and output images ) or intermediate flags can be used any number of times as these are soft signals when implementing the logic.
The advantage of this method is that even at the beginning of a project ( even during the cost estimation stage ) one can estimate the number of inputs and outputs and decide the type of the PLC. https://instrumentationtools.com/ need not even be fully clear about the logic or the total functionalities to estimate the PLC-s. An example for selecting the number of inputs and outputs is given in one of the following sections . The types of industrial inputs and outputs are discussed first . They are the commonly used input devices They have basically two parts - operating buttons (actuators) and the contact units.
Normally 2 N/O and / or 2 N/C contact blocks are common when used with the conventional relay based control panels. With PLC based system, the input block need only be 1 N/O or 1 N/C. This input along with their complement can be used any number of times in the PLC ladder diagrams . The operator buttons are of different types; i. The buttons are normally with different colours, like the indication lamps to be described under the outputs. Green is normally used for ‘on’ functions and ‘Red’ is used for ‘off’ function; other colors like yellow, black etc are used for other functions like start, stop, jog, thread etc. functions.
Sometimes the mushroom headed red coloured off (emergency) PB actuators get mechanically latched when pressed; They need to be turned in one direction to release the same. They are selected for certain locking type control functions like enable / disable or forward / reverse selection type respectively. Some times the PB actuator unit has a transparent head(with appropriate coloured lens) with in built indication lamp, apart from the contact blocks. These are normally used to sense the reaching of the required physical limit by a machinery or a motion control system. The limit switch operates on physical contact and closes a switch provided with N/O and N/C contacts.
Here the rotary limit switch arrangement is coupled to the motor or the actual load shaft driving an operation. The coupling is through an appropriate gear box so that for number of revolution on the equipment shaft side, the limit switch shaft rotates once. On the limit switch shaft are number of cams and the cam actuation positions are set at the required appropriate angles. These cam settings are adjustable programmable. With this arrangement the individual cams operate the associated limit switches. The operation of these limit switches can be associated with the reaching of appropriate limits in a linear travel; eg.
Position vi. Stop ; top position for tipping the material into furnace. However they require external power supplies. 1. They also function as limit switches but without physical contact. 2. There are two types - called inductive proximity switches or capacitive proximity switches which operate due to changes in the magnetic field or the capacitance value under the proximity of the part or item being sensed. These switches also require external power supply and the outputs are normally open collector transistor type to which an external relay can be connected or can be a direct input to PLC input card.
3. These proximity sensors can also be used to measure the speed of a motor or drive by non-contact method. Of the above mentioned inputs, many of them are on/off type (either potential free contacts or open collector type) and are called as digital inputs and some of them are providing analog inputs for continuous controls. There are also other soft inputs like the keyboard inputs etc. but they do not form hard wired inputs. The above mentioned devices are input devices for a relay and PLC control system. There are also number of output devices which get connected to a relay or PLC based control system. The functioning of contactors are similar to relays; Additionally contactors have 3 or 4 power N/O contacts (normally) which is used to switch on the power.
The contactor coils are energized through PLC output or another relays contact and through the coil power supply (110VAC, 220VAC, 415VAC etc). DC supplied coils are also present some times. The contactors are normally used to switch 3 phase AC power to say a motor or a power modulator or such an application and they are extensively used. Contactors are normally available in various sizes (size 0 to size 16 - corresponding to 16 A to 630 A and more). Most of the contactors are for AC power switching. There are also DC power switching contactors available. They require special arc- chutes for lengthening the arc.
Hence these DC contactors are more expensive and need to be carefully selected. All contactors have auxiliary contacts for inter locking and relaying functions. 2 N/C contacts are provided for these auxiliary functions. Apart from the selection of contactors to match with output load current and voltage, they need to be selected, also considering the numbers of operating cycles per hour. Like a relay and contactor, the solenoid is an electro-mechanical device. In this the electrical energy is used to magnetically cause a mechanical movement. The solenoid; like the contactor has a frame, plunger and the coil. The coil is energized by AC or DC voltage.
Upon the application of the voltage to the coil, the corresponding plunger is pulled back through a spring in case the coil voltage is interrupted. The AC solenoid draws a large in-rush current on energizing, when the plunger is fully out. The current drops to minimum value when the plunger is fully in. Due to this, it is important to ensure that the solenoid is fully energized i.e. the plunger is fully in. Otherwise the solenoid coil will take more than rated current continuously resulting in the burn-out of the coil. As against this, DC solenoid takes a constant coil current; but AC solenoid has superior initial pull.
For many industrial applications, 24V DC solenoids are normally preferred. While the contactor as output devices are selected based on the load current and voltage requirement, the solenoids are normally selected to handle appropriate pressure, force or weigh to be lifted etc. Accordingly the solenoid size varies. 1. Single solenoid (with one motion) with one coil. When it is energized it moves against the spring and when de-energized comes back to original position. 2. Single solenoid (with one motion) but with two coils. This is similar to above but with latching feature. One coil is for switching on and another is for switching off.
3. Double solenoid (with two motions, say up / down) and with two coils. When one coil is energized, the motion is upwards and downwards when the other coil is energized. It goes to neutral position when both the coils are not energized. 4. As it can be understood the number of coils to be energized decide the number of outputs per solenoid to be considered by the PLC. Normally the above solenoids are on/off devices; some times it is required to provide a motion which is proportional to the supply current amplitude. There are also continuously adjustable devices - e.g screw down in a rolling mill, measuring gauge adjustment for a cut length etc which are controlled through a proportional control system based on electrical motors or hydraulic valves .

SESSION 8
Bodies remaining around us: kid, two other bodies, one Herald corpse, one mook corpse, one undryad corpse. Bodies dragged into forest: sneak, two Heralds.
Brianne examines the Herald corpse. Lots of places where it’s shifted, transformed. Happened after death; not wounds, but its flesh struggling to keep up with its metamorphosis. Torso hollowed, less internal organs; ribcage grotesquely grown to accomodate muscles. Along spine and forelimbs, rows of metallic spikes growing out of it. These spikes are similar to the smaller spikes used for the dryad, but NOT the larger one, which was more intricate, shaped, gold inlay. Abyssal runes on them. (Note: the corpses in Ulthar’s tower did not have a big spike, only the Herald spikes.) Brianne reads the script: an abyssal prayer “We purify the weak, and rise in glory.” They all say the same thing. No discernable tool marks.
Brianne gets Ghorza to rip one of the spikes out, dripping with ichor. She then cuts it open to discover its bones are now the same metallic substance as the spikes. The bones are ALSO etched with Abyssal; it appears to say something else, but the ribs appear to be in the middle of something. She recruits ghorza again to help flay the flesh from its bones; Brianne fucks up during the autopsy and something bursts, releasing a nauseating scent of decay. She pukes (away from the body).
We eventually manage to peel off enough flesh from bone to get the gist. It reads like a religious text - mentions of Galaias, [her return from… entrapment? Somewhere.] The Herald is a walking unholy text, with prophecies etched into its bones. [With Primeval Awareness, Brianne detects more undead are in Mielikki’s Arbor, and six more suddenly appear there.]
Finally we go back inside to reunite with the cuddlepile.
Meanwhile, inside: Cadence is tending to Apphia’s near-mortal wounds, cleaning her etc. Kelsey anxiously asks if Apphia’s titties will be okay.
Megs, the only one who’s not preoccupied, talks to Juna alone. It turns out she knows the living bruiser, Valden Bray. (Gwen: “Can I roll insight to see if they fucked?” - Megs actually does but gets a 6 :P ). When she realizes he was one of the ones snooping in the barn, she charges in, grabs him by the collar, and demands an explanation while dangling him in the air.
He says he got mixed up in some bad shit, he needs food for his family and can’t lumberjack, so he signed up with the castle, but then it got ‘weird.’ He repeats that he was looking for the lens, sent on behalf of ‘someone above Brandt’.
Juna: “And so what, you were going to kill my family?! My parents, my siblings? Give me one good reason I shouldn’t burn you from the inside out!” (Kelsey: “Roll insight to see if they fucked!”) There’s another couple of the Vardanes, tall teenage boy and shorter girl, and Apphia and Cadence coming down now. Apphia DOES roll, and determines that they have made out but not fucked. Ghorza and Brianne come in now too. “I can’t believe this sniveling bastard sold out my family!”
He agrees to talk more; Juna lets him down, then decks him in the face again. He mentions the sneak was all about the ‘cause’ - says the people ‘holed up in Castle Aldessein’ are all weirdos. Mentions Martin, the bruiser we killed in the barn - Ghorza interjects “I think if you search your memory you’ll find he was killed by the zombies.” He mentions the margravine was more or less forced to leave by Brandt et al. The weirdos are part of some kind of cult, “Harbingers of the Dark Sun.”
Some of the group know of this cult - the cult of Cyric, triple-crowned king, god of lies and murder, whose followers are sometimes known for controlling the undead, binding them under their will. (Gwen: “Do you think someone would really do that? Just put on hats and tell lies?”)
Valden says there were services held in the dungeons at night. Carm was really into it. Carm and Nemeth run the show there. Brandt is a pawn they installed; Nemeth tells him what her superior wants and he makes it happen. The cult is everywhere - in all the marches and Isvanir - communicating with each other, keeping tabs on our movements, etc. The Margravine is being poisoned to keep her weak but alive.
Nemeth is apparently a tiefling too. Gold eyes, red hair, dark skin, horns, tail. Quiet, keeps to herself; doesn’t interact with the grunts much (Brandt does that). Looks like a warrior? Talks mostly to Brandt, Carm, the lieutenants sometimes.
Carm - the worst of all of them. Extremely creepy. Human. Keeps tabs on everyone. REAL into Cyric. Slight, pale, sandy brown hair, blue eyes. Coldest stare. Carm overheard another grunt talking about not being into Cyric; he disappeared and the altar got more bone decorations.
Cassath and Dresna - lieutenants. “Mostly just into each other” - no insight check needed, they’re fucking all the time; they’re probably fucking right now. Cassath is a high elf, from Isvanir. Light, short, messy brown hair. And she’s a witch? Scarred, burned hands (from acid). Cruel, but not really into Cyric. Dresna - half-orc, short black hair. She’s sneaky and creepy. Not as cruel as Carm, not really into Cyric; just there for Cassath.
Apphia knows of Cassath - an exiled criminal, from the slums where the Tarjanir refugees were. Ran a illicit alchemist shop, made acids. Made a lot of mayhem, was sentenced to be executed many years ago.
Ghorza knew of Dresna - she was in Vassarein’s army. Perennial bad example for the troops; didn’t play well with others. Robbed the armory and vanished.
Only one other person of importance, who Owen told us about, was the greasy, light-figured, shifty-looking guy who would swing by occasionally to deliver reports and talk to Nemeth and Brandt. No one who matched the description of Gulden, or the one Ulthor fought at the ruins.
Correspondence to Isvanir - maybe upstairs in the keep?
Albrecht - former castle guard. Erik knows him, recommends we talk to him. Dancing Dryad inn. Left when the cult took over.
Helene wants to get the family out of here, to safety. We decide that - after we burn the bodies - we’ll take the Vardanes into town and get them room in the inn. And Valden, we guess. Then we’ll rest up for the night.
We burn the Mortens (neighbors) and the herald and Martin (the bruiser). (Burned body count is up to 19).
We can now read some more of the remaining bones of the Herald, now that the flesh is burned up. [Brianne has heard some of these prophecies in her dream. Galaias returns under a sky of blood, upon a road of bone. She was sealed away on the Material Plane millenia ago. ‘From the ranks of her enemies, a spiteful soul will draw her forth.’]
Juna has a gift for Ghorza and Apphia, before we leave - she gives them a Ring of Necrotic Resistance and a Ring of Protection, and heartfelt hugs. It’s really gay!
We go into town - Cadence has shifted into a horse, and Megs and the kid ride her. Apphia is in the cart, being held in Juna’s strong arms. She gets the Cloak of Comforting.
Brianne, Apphia, Helene, Juna, and the kids check into the inn. Meanwhile, Eric takes Ghorza and Valden with to go find Albrecht. We’re rounding up a posse to save the people in the outskirts! Cadence stays a horse. She takes off on a run with Megs on her back.
The cost of putting up the Vardanes is 114. We split that five ways.
We find a stoic elven man with dark skin nursing a drink. Albrecht is Erik’s ex bf for sure. He perks up slightly when he sees Erik. He explains the situation with the undead attack. Albrecht toys with a dagger while looking at Valden, who admits he’s shit. Albrecht says he’ll round up his men. He also says he’ll put Valden to work helping to fix things once.
We discuss tactics on how to fight the things, that they should run away from the undryads if they see one. Ghorza tells Albrecht they’ll try to rescue the Margravine and reinstate her, which he fervently hopes they do.
Meanwhile, Cadence and Megs are out looking for flowers. They… find some weeds. They then try to go to Ghorza’s moms’ bakery, but forget it’s in a different city. Luckily, Megs has fantastic Investigation and finds an awesome bakery, and they get lots of pastries. They also get nice meals and wine to bring back to the party? So cute!
Imp: “And you brought us weed! Can I roll for how dank it is?”
Kelsey: “She needs to ride back in on me, looking dashing as fuck on the noble steed-” Lin: “Roll Charisma.” (Cadence rolls an 8, but at least Megs manages to roll a 22). Lin: “Peasant girls look out their windows, sighing, a merchant woman leans out of her booth and gives Megs the nod.”
Cadence fucks up and turns back before Meg dismounts, which spoils the effect a bit. Cadence druidcrafts the weeds into lovely flowers.
Ghorza gives Cadence a big hug and spins her around, and Cadence smiles for the first time that day. They share with the Vardanes too, and Juna hugs them as well. Megs redemption arc complete!
Lise and Armand - the Vardane kids. Lisse is like 7, Armande is 14.
We prepare to rest for the night. (Brianne buys our rooms. (It’s gay).) Tomorrow we storm the castle dungeons! Valden’s gonna be leading us in; we’ll put up the ruse that we’re on their side and Megs is bringing in the lens. Apphia will have the actual lens, and will show Valden the real lens as proof that we’ve had it all along. Then she’ll hide it on her person, and make an illusory copy.
Apphia and Brianne go out to get Apphia a new top, although Juna had Mending’d her shirt. Shopping episode~! After Brianne helps her find one, Apphia decides to get her a super soft nice cloak… OF BILLOWING! It’s all super gay. As they walk back, Brianne brushes her hand against hers, and Apphia takes her hand and swings their arms as they walk back.
Cadence, with a few drinks in her, finally shares her nightmares (or, trauma flashbacks) - a unicorn which was an Exarch(?) of Mielikki was corrupted into a undryad-like beast, and chased her out of the arbor. We have a big group hug.
Brianne: “If I’m super gay for Apphia, does that make me an Apphiest?”
Megan: “If Brianne wants to have the gay panic long rest, she can bunk with apphia.”
End of session, and day 3.
