Advanced Technological Interface

•Integrated Biosensors: Built-in biosensors that can analyze blood or interstitial fluid samples to measure viral load in real time.

•Data Analytics: Utilizes algorithms to process biosensor data, providing insights on viral dynamics and trends.

•Alerts and Notifications: Real-time alerts sent to the user or healthcare provider when viral load exceeds predetermined thresholds.

•Communication System: Integrated with a communicator on the wrist, the arm serves as a reliable device for maintaining contact with his team. This system includes encrypted channels for secure communication during high-stakes operations.

•Objective Management Display: The arm features a holographic display that provides a detailed version of the communicator’s data, allowing Piers to view mission objectives and tactical data in real-time. This feature minimizes the need for external devices and keeps critical information accessible.

Augmented Reality (AR) Compatibility

•Enhanced Visualization: The arm’s display projects augmented reality overlays, allowing Piers to see additional information, such as enemy positions, weapon stats, or tactical directions, directly in his line of sight.

•Environmental Scanning: The arm can analyze the surroundings for potential threats, detect biological or chemical hazards, and provide alerts for safer navigation through hostile environments.

Electricity Conduction and Control

•Energy Conduit Design: The bionic arm acts as a conductor for the constant electrical energy generated by Piers’ mutation. It includes specialized channels and circuits designed to manage this energy flow, allowing Piers to use his mutation’s electrical pulse without it spiraling out of control.

•Dielectric Structures: The arm’s design incorporates materials that mimic the dielectric properties of his mutated tissue, particularly in the finger joints and bones. These dielectric components help regulate and contain the high voltage his body produces, diffusing excess energy safely throughout the arm.

•Controlled Release Mechanism: To avoid overload, the arm features a controlled release system that allows Piers to release pulses of energy strategically, whether in combat or to alleviate the internal buildup. This system prevents the arm from overheating or sustaining damage from prolonged electrical activity.

Containment and Compression of the Mutation

•Compression Framework: The prosthetic was specially designed by UMBRELLA engineers to act as a containment “net” around his mutation. It includes a flexible, reinforced framework that compresses the mutated tissue, keeping it in check and preventing further growth or erratic shifts in form.

•Adaptive Pressure System: As the mutation strains against the arm, sensors detect any changes in size or energy output, triggering adaptive responses. The arm tightens or loosens as necessary to hold the mutation back, functioning almost like a high-tech brace that adjusts in real-time to maintain Piers’ arm in a stable form.

•Automatic Safety Lock: In the event of a significant spike in mutation activity or electrical output, the arm engages an emergency lock to keep the mutation from expanding. This feature is a safeguard against sudden bursts of energy that could cause the arm to revert to its mutated state.

Dependency and Risks of Removal

•Rapid Mutation Onset: Without the prosthetic in place, Piers’ arm begins to mutate almost immediately, returning to its original, unstable form. The electrical pulse that his body generates becomes unrestrained, emitting a continuous, breath-like rhythm that is both painful and dangerous, with energy leaking through protruding bones and exposed tissue.

•Uncontrollable Pulse: When uncontained, the electrical pulse from his mutation surges in intensity, lacking any natural “closure” or stopping point. This pulse causes rapid fluctuations in his vital signs and risks systemic overload, leading to loss of control over his mutation and putting him at severe physical risk.

Miscellaneous Details

•The arm has a unique serial code engraved on an inner plate, serving as an identifier for UMBRELLA technicians. This code also links to Piers’ personal health records, mutation data, and arm specifications for quick access during maintenance or in emergencies.

•Due to the intense electrical pulses generated by his mutation, the arm is equipped with an internal cooling system. Micro-fans and heat-dissipating channels prevent overheating during extended use, keeping the arm at a safe, comfortable temperature. If the arm overheats, an internal alarm alerts Piers to prevent any potential damage.

•The outer layer is treated with a UV-resistant coating to protect it from environmental damage and exposure. This ensures that prolonged exposure to sunlight or harsh conditions doesn’t wear down the arm’s exterior, making it more durable in diverse climates and situations.

•Designed for various operational environments, the arm is fully waterproof and corrosion-resistant. It functions normally underwater, which is crucial for aquatic missions or when exposed to rain, mud, or corrosive substances.

•The holographic display can be customized to show additional details, such as weather, GPS navigation, or tactical maps. Piers can also set personal preferences, like color schemes or alert tones, for a more intuitive user experience. This flexibility lets him prioritize the information he finds most critical during missions.

•The communicator has an onboard language translator, enabling Piers to communicate with individuals across different languages. The arm’s display shows translated text, and a subtle earpiece can even relay audio translations, making it easier for him to gather intel and negotiate in multilingual environments.

Let me introduce my current main WIP. It's not fandom related, it's for my model railroad, and it's not yet finished.

This is a rendering of a circuit board that I'm designing at the moment. It will be a DCC command station. My model railroad is run digitally, which means the tracks carry digital signals that tell each locomotive and switch individually how to run, which lights to turn and so on. The command station is the device that generates that. I have a number of different layouts, one of which has a good command station, one of which has a crappy old one, and the final one isn't even digital yet. So this will be the one that solves all issues for me, hopefully.

The design above isn't finished yet, and even the parts that are are not yet fully representative. The different capacitors are just there as options; some screen print overlaps; and some components (in particular all plugs and the relays that control the programming track) don't have 3D models so they don't show up.

Planned features:

Four layer board

10-25 V DC output, software controllable

Up to 5A output power, limited mainly by the main switching regulator.

Input 15-25V either AC or DC with polarity protection, selectable with some solder bridges (not yet in there). Optionally you can also bypass the main power regulator with another solder bridge (that I haven't added yet); useful in case you use e.g. a laptop power supply with a switchable voltage and don't need any regulation after that.

Railcom support

USB connection; not yet sure what for, but the main chip I'm using has USB support and I have some spare USB connectors here, so in it goes.

Speaking: The chip is an STM32L433RCT6P, chosen because I found it in stock at an electronics distributor. 64 kB RAM, 256 kB EEPROM, with support for an additional up to 256 MB externally (there's a spot for that on the board) and lots of fun extras that I don't technically need. It has an FPU! I don't need an FPU, but I will definitely do some floating point math computation on it just for fun.

Main external connection is WLAN using an ESP32 WROOM U module. I haven't decided on the housing, but I may go for extruded aluminum, so it's the U version that allows and requires an external antenna

It supports XBUS/XpressNet connections for old throttles from Lenz and Roco that I should probably throw away, but I paid good money for them, dang it.

It supports CAN for LCC / OpenLCB. I may not populate this part on all boards that I'm building, because I haven't actually decided whether I am interested. But the chip has CAN functionality built in, so why not.

There's an I2C connection to connect a cheap tiny OLED display for status messages.

Test points for all important signals (in particular the different internal voltage levels; yes, there is 3.3V, A3.3V and -3.3V and I need all of them).

Stuff still to add:

I will add pin headers (or space for pin headers anyway) for all the remaining pins on the STM32, and perhaps some on the ESP32, for future expansions.

Status LED and stop/go button on the front

Wire it all up, maybe move some stuff (mostly the STM32 around), which will cause all sorts of fun new routing issues.

Adjustments to make the jacks line up with the front panel once I've decided on a housing.

Features I'm not considering adding:

s88. I vaguely know what it is but I don't have any devices like that, and if that ever changed I could probably build (or perhaps buy) a converter that connects them via CAN.

Other buses like LocoNet.

Ethernet. I don't need it and it's actually more expensive than WLAN in this day and age.

In terms of software, I'm planning to use DCC-Ex on it. The whole project actually started out as a DCC-Ex shield, but once I realised that this wouldn't fit, I decided to make it standalone. Now, DCC-Ex is designed for Arduino, not STM32, and it doesn't support XpressNet, nor OpenLCB, nor Railcom, and their Wifi protocol is pretty weird and annoying which will be an issue (I'm planning to write my own control app for iPhone for it), so I'll probably change that or just replace it with the z21 one… so really, the software will not look a lot like DCC-Ex once I'm done with it.

Will this all work? I have honestly no idea. I mean, I'm fairly confident, I'd have given up on this long ago otherwise, but I have no guarantees either way until I've spent a lot of money on components and circuit boards and start soldering. Turns out doing it this way is not really cheaper than just buying a half-way decent one. That's what makes it exciting, though!

If it does work, obviously this will be released as open source. But it's still going to be a few days (more realistically weeks) before it's even ready to order the parts, and then a lot of soldering (current BOM stands at 194 actual components), and then a lot of software development before it's ready for that.

The Principle Behind AC-DC Rectifiers

AC-DC rectifiers are essential electronic devices that convert alternating current (AC) into direct current (DC). This conversion is crucial for powering electronic devices and systems that require a stable and constant DC voltage. Understanding the principle behind rectifiers involves examining how they manage the flow of electric current to achieve this conversion.

Basic Principle of Rectification

Rectification is the process of converting AC into DC. The principle behind rectifiers relies on the use of semiconductor devices, such as diodes, to control the direction of current flow. Here’s a step-by-step explanation of the principle:

AC and DC Basics:

Alternating Current (AC): AC is an electric current that reverses direction periodically. It is the type of current supplied by power grids and used in most household appliances.

Direct Current (DC): DC flows in a single direction and provides a constant voltage. It is required by many electronic devices and battery-powered equipment.

Role of Diodes:

Diodes: Diodes are semiconductor devices that allow current to flow in only one direction. They have two terminals: the anode and the cathode. When the anode is positive relative to the cathode, the diode conducts electricity; when the anode is negative, the diode blocks current flow.

Half-Wave Rectification:

Principle: A half-wave rectifier uses a single diode to allow only one half of the AC waveform to pass through, effectively blocking the negative half-cycle of the AC signal.

Operation: During the positive half of the AC cycle, the diode conducts and allows current to pass, creating a series of positive DC pulses. During the negative half of the cycle, the diode blocks the current, resulting in zero output.

Full-Wave Rectification:

Principle: A full-wave rectifier uses multiple diodes (usually in a bridge configuration) to convert both halves of the AC waveform into DC.

Operation: In a full-wave rectifier, the positive and negative halves of the AC signal are both used to produce a continuous DC output. This is achieved by using either a center-tap transformer with two diodes or a bridge rectifier with four diodes arranged in a bridge configuration.

Rectifier Circuit Design:

Transformer: In many AC-DC rectifier circuits, a transformer is used to adjust the AC voltage to the desired level before rectification. It can step up or step down the voltage as needed.

Filter: After rectification, the DC output often contains ripples or fluctuations. A filter, typically composed of capacitors and inductors, smooths out these ripples to provide a more stable DC voltage.

Regulator: For applications requiring a precise DC output voltage, a voltage regulator may be added to the circuit to maintain a constant voltage despite variations in input or load.

Applications of AC-DC Rectifiers

Power Supplies: AC-DC rectifiers are used in power supplies to convert AC from the mains into DC for powering electronic devices and equipment.

Battery Chargers: Rectifiers convert AC into DC for charging batteries in various applications, including automotive and consumer electronics.

Industrial Equipment: Rectifiers provide DC power for motors, control systems, and other industrial machinery.

Communication Systems: Rectifiers ensure a stable DC power supply for communication equipment and network infrastructure.

Renewable Energy Systems: In solar and wind power systems, rectifiers convert AC generated by inverters into DC for storage or use in DC-based appliances.

Conclusion

The principle behind AC-DC rectifiers involves using semiconductor devices like diodes to control the flow of current and convert AC into DC. By allowing current to flow in only one direction, rectifiers effectively transform the alternating waveform into a direct one. This conversion is essential for providing stable and reliable power to a wide range of electronic devices and systems. The basic rectification process, along with the use of transformers, filters, and regulators, ensures that AC-DC rectifiers meet the power requirements of various applications, from household electronics to industrial equipment.
