Capstone #6: Solid
<-<- FIRST || <- PREV || NEXT ->
Tumblr media
CAD is nearly done, and the design is 95% there. There's still some improvements to be made. Big 'ol hand to our CAD team especially for bringing this to life. Lets explore under the cut
There's 2 main parts of this thing. The main body has the fans and wheels. The gantry on top does all the doodling. Let's pop the top off.
Tumblr media
The cover and walls are purely aesthetic and keeps the dust out. Originally the cover is held on using snap buttons, but that's been changed to the tiniest magnets pocket change can buy. The base plate is made from thin wood, or we've been exploring carbon fiber (but that's proven to be mad expensive for basically no gain. Like 400+$ expensive).
The wheels are servos, the fans sit side by side and run off wall outlet power. (Try making these drone motors that normally run off batteries, and make them run off a wall outlet. Sounds easy right? Good luck. It's been a time doing it. They eat something like 12-16v at 40-60+ amps... *each*). It's got tiny nubs on the bottom to stabilize it, because with only 2 wheels, it's going to want to rock side to side. It'll have some distance sensors on the sides to find where it is on the wall, and an accelerometer to find how it's tilted. I'm personally a little worried the vibrations from the fans will make the accelerometer unreliable, but we'll find out about that later. The whole thing will be controlled by an Arduino Mega.
Tumblr media
Smooving over to the gantry, both axis will be on rails purchased from Igus. The rails are made from hard anodized aluminum, while the carriages are made from diecast zinc and some slippery bearing plastic. It's then pulled around by timing belts and steppers. We modified both axis a tad by reducing the rail size to the smallest ones Igus offers, and giving the horizontal axis 2 rails for more stability (The bearing situation on the timing belts were improved too)
Tumblr media
The printer head uses an electro-magnet to pull the pen down. There are guide pins with springs to, well, guide and spring return the head. There are also stop screws that set the maximum engagement and disengagement. (The travel distance is kinda exaggerated here tho. The actual travel distance will be as little as possible. Like 3-4mm)
All in all, the bot body is something like 300 x 500mm, 60mm thick (+ 55mm for the fan tails), with a print area of 150 x 150mm. We've tried to cut as much weight as possible, and are looking at about 1.2kg or a little lighter than a small toaster
Tumblr media
As a bonus pic, here's an early concept. This one uses a lead screw for the X, and a shaft and timing belt for the Y. If you're wondering what stops the axis from pivoting, it would have been some gibs located behind both axis. Commonly used on dovetails, a gib is when you intentionally design in a large gap between your mating surfaces, and shove a thin plate in there with setscrews to take up the slack. Look at the ways of basically any milling machine or lathe, and chances are you'll see one!

Vibration Analysis in Gearboxes
Vibration Analysis in Gearboxes represents a critical practice within predictive maintenance and condition monitoring that ensures the health and longevity of rotating machinery. Gearbox vibration diagnostics plays an essential role in industrial environments, offering early detection of gear tooth damage, misalignment, imbalance, bearing faults, and lubrication issues. Employing advanced technologies like wireless sensors, spectrum analysis, and frequency domain monitoring under the auspices of modern Industry 4.0 frameworks, businesses can dramatically reduce downtime, improve safety, and optimize asset performance.
Understanding Gearbox Vibration Signatures
Every gearbox emits a distinctive vibration signature during normal operation. When abnormalities occur—such as cracked gear teeth or insufficient lubrication—the vibration amplitude and frequency patterns shift. Detecting these deviations through time waveform analysis and spectral signature comparison enables accurate diagnosis. Technicians often use accelerometers, velocity sensors, and displacement probes to collect data, which is then processed via Fast Fourier Transform (FFT) to isolate harmonic peaks indicative of specific faults. Vibration velocity, vibration acceleration, and harmonic resonance are key terms in this deep analysis. Software platforms like AI‑driven analytics interpret trends in real time, giving maintenance engineers insight into degraded conditions before catastrophic failure.
The Role of Condition Monitoring and Preventive Maintenance
Condition monitoring, which encompasses vibration monitoring, temperature measurement, oil analysis, and acoustic emission, forms part of a broader predictive maintenance strategy. Vibration analysis in gearboxes has emerged as one of the most powerful tools in this toolkit. By establishing a baseline signature and continuously tracking changes, engineers can schedule targeted maintenance interventions at the most cost‑efficient time rather than responding to breakdowns. This approach improves reliability, extends equipment lifecycle, and maximizes ROI. For large‑scale plants, remote monitoring systems provide these alerts 24/7, integrating with industrial IoT networks and cloud computing.
Real‑World Applications and Industry Use Cases
Vibration analysis in gearboxes is used extensively across sectors such as cement, mining, metals, chemical, and oil & gas. In cement plants, for example, gearbox vibration monitoring helps detect wear early in ball mill drives, preventing unexpected downtime and associated revenue loss. In mining, trackless mobile machinery with complex gear-driven drivetrains benefits from spectrum analysis of gearbox vibration to uncover misalignment or gear wear. These real‑world implementations often combine wireless vibration sensors mounted on gearbox housings with AI‑powered platforms that load the data into dashboards, sending alerts via SMS or email to maintenance teams with precise fault frequencies flagged for inspection.
Wireless and Remote Sensing Technologies
Modern condition monitoring systems increasingly leverage wireless vibration sensors for gearboxes to facilitate easy installation and enhanced data coverage, especially in harsh or hazardous environments. Wireless accelerometers and triaxial vibration sensors can capture X, Y, and Z axis data along with reference phase channels, ensuring a comprehensive monitoring solution. These devices can be battery‑powered or light‑harvesting, capable of running for years without manual calibration. Wireless systems allow technicians to deploy plug‑and‑play sensors on gearbox casings, with data transmitted via Wi‑Fi or LTE directly into analytic engines. Remote monitoring greatly reduces manual route‑based inspections and ensures real‑time anomaly detection with minimal intervention.
Advanced Analytics and Fault Diagnosis
Once vibration data is captured, anomaly detection algorithms assess it against baseline signatures to identify fault conditions. Frequency domain features such as gear mesh frequency, shaft order harmonics, sidebands, and modulated signals are evaluated using AI and physics‑based models. A good example is the detection of a cracked gear tooth. When the defect enters the load zone, it generates an impact at the gear mesh frequency. Spectrum peaks or amplitude modulation help isolate this fault. Similarly, insufficient lubrication produces friction‑induced noise visible in broadband vibration. These diagnostic insights help create actionable maintenance work orders.
Integrating Vibration Analysis into Predictive Maintenance Platforms
Leading condition monitoring platforms integrate vibration, temperature, acoustic, and magnetic flux data into a centralized system. These predictive maintenance solutions ingest sensor readings, compare deviations using statistical thresholds, and alert reliability teams when gearbox vibration exceeds acceptable levels. Dashboards display severity via color‑coded hierarchies, enabling teams to prioritize maintenance. Predicting Remaining Useful Life (RUL) of gearbox components based on trending vibration signatures ensures maintenance decisions are data‑driven and aligned with business objectives. Integration with asset management systems triggers service schedules, parts ordering, and alerts without manual interfaces.
Benefits, Challenges, and Best Practices
Adopting vibration analysis in gearboxes delivers multiple benefits: reduced unplanned downtime, cost savings, improved safety, extended equipment life, and data‑driven maintenance decisions. However, challenges include establishing accurate baselines, sensor placement on complex gearbox geometries, environmental noise interference, and ensuring sufficient sampling rates for high gear mesh frequencies. Best practices include selecting high‑quality accelerometers, performing route verification, combining time and frequency domain analyses, and calibrating AI models to local operating conditions. Engagement of multidisciplinary teams—mechanical, reliability, and data science—is critical to maximize system effectiveness.
Conclusion
Vibration Analysis in Gearboxes is an indispensable aspect of modern condition monitoring and predictive maintenance regimes. Through vibration spectrum analysis, wireless sensing, advanced analytics, and cloud‑based platforms, organizations can detect gear faults, misalignment, bearing issues, and lubrication deficiencies long before failure occurs. Real‑world use cases in industries like mining, cement, and oil & gas demonstrate tangible gains in uptime, safety, and cost reduction. By embracing these technologies and following best practices for sensor deployment and data analysis, businesses can optimize asset health and performance. Through expert vibration diagnostics integrated into predictive maintenance systems, manufacturers and heavy‑duty operations transform reactive maintenance into proactive reliability programs.

In this detailed guide, we delve deep into the workings, applications, and benefits of gyro sensors to provide you with a comprehensive understanding of their importance in today’s digital and mechanical world.
What Is a Gyro Sensor?
A gyro sensor is an electronic device that detects the rate of rotation around a particular axis. It helps systems determine orientation and rotational motion by using the principles of angular momentum. Unlike accelerometers that measure linear motion, gyro sensors are essential for sensing rotational dynamics.
There are several types of gyro sensors, including:
MEMS gyroscopes (Micro-Electro-Mechanical Systems)
Fiber optic gyroscopes
Ring laser gyroscopes
Vibrating structure gyroscopes
Each type has unique characteristics suitable for different applications, ranging from compact consumer electronics to high-precision aerospace systems.
How Do Gyro Sensors Work?
At the core of most modern gyro sensors, especially MEMS gyroscopes, is the principle of Coriolis Effect. When an object rotates, the Coriolis force is exerted on a vibrating structure inside the sensor. This force causes a change in the vibration direction, which the sensor interprets to calculate the angular velocity.
The steps involved in gyro sensor operation include:
A tiny mass inside the sensor vibrates at a consistent frequency.
When rotation occurs, the Coriolis force alters the path of the vibration.
This deviation is detected by capacitive or piezoelectric elements.
The sensor processes this data to determine angular speed.
Key Features of a Gyro Sensor
When choosing or designing a system with a gyro sensor, understanding its critical features is essential. The most notable features include:

Building Custom HomeKit Devices
Tumblr media
Have you ever caught yourself thinking, “I wish there was a HomeKit device that could do this…”? Yeah, same here. For me, it was wishing my washer-dryer could send a notification when the laundry’s done. See, it’s out in the yard—so if you’re chilling in the living room with the TV on, you’d never hear the washing machine’s faint beep of completion.
Luckily, I had a few ESP32s and sensors collecting dust in a drawer, so I thought: Why not build one myself? With a little help from AI, of course. I’ve been bouncing between Gemini 2.5 Pro, Grok, and ChatGPT, and they’ve been surprisingly great sidekicks. Sure, I could’ve sat down and studied all the libraries and frameworks properly—it might’ve taken me a couple of days tops (I’ve been around the programming and electronics block a few times). But thanks to AI, I hacked together a working prototype in just a few hours.
Now, this isn’t a tutorial—that’s coming soon once I’ve fine-tuned everything and properly tested my DIY HomeKit setup. This is more of a quick peek behind the curtain. A little show and tell.
Tumblr media Tumblr media
For the build, I used an ESP32-S3 WROOM-1 (N16R8) and an MPU6050 3-axis accelerometer. Total cost? Around 7 bucks. Hooking up the sensor via I2C was simple enough. When any of the AIs got confused or hit a wall, I just tag-teamed between them until I got what I needed.
And here’s the result after just a few hours of tinkering—Apple’s Home app picked up my custom HomeKit device without a hitch. The best part? Seeing “ChrisTan Workshop” proudly listed as the manufacturer. Cracked me up. Nothing like a bit of DIY flair baked right into the Home app!
Tumblr media Tumblr media Tumblr media Tumblr media
Here’s a quick rundown of how the magic works: the MPU6050 accelerometer monitors for vibrations. If it detects continuous movement for more than 20 seconds, we assume the washing machine is doing its thing and mark it as “running.” Once it stays still for over 3 minutes, we take that as a sign that the laundry’s done. These timings—and a few other parameters—are all configurable. I’m still fine-tuning them to match the quirks of my Electrolux washer dryer.
One of the trickier parts (and where all the AIs struggled a bit) was figuring out how to send a proper HomeKit notification. After some back-and-forth, we found a clever workaround: register the device as a doorbell. That way, when the laundry finishes, my HomePod mini chimes and a notification pops up like someone’s at the door. Not exactly elegant, but hey—it works! I just wish HomeKit gave us more flexibility with custom notifications, but I get it… Apple’s probably trying to prevent spammy alerts from rogue accessories.
Tumblr media
That’s it for now. Eventually, I want to make this whole thing easily user-configurable—no coding required. But for the moment, a few parts are still hard-coded under the hood.

The adoption of technology in the field of medicine has resulted in some amazing innovations. These innovations have helped in making healthcare more efficient, personalized, and convenient. Smart technology in healthcare includes technologies such as artificial intelligence, big data, the internet of things services, and cloud computing. In this article, we’ll look at the top examples of smart technology in medicine.Smart InhalersAsthma is a health condition that affects millions of people around the world. Through smart technology, people with the condition can gain better control of their symptoms and treatment by purchasing smart inhalers. A smart inhaler includes a sensor that is connected to an inhaler or a Bluetooth spirometer. This sensor is then connected to an app to help the user track their medication use, identify oncoming attacks, and learn more about what might cause their symptoms. This technology helps the user to take the correct medication consistently and generates reports that can be shared with a doctor.AI-powered Insulin PumpThis was first developed in 2014 by Bryan Mazlish. He developed this by modifying an off-the-shelf insulin pump and a continuous glucose monitor. He created an algorithm that controls the dosing and an app to display the results. The device includes a metabolic simulation engine that predicts the insulin dosage and when the patient will need it, instead of only responding to increases in blood sugar. This technology is preventive rather than curative and thus benefits the patient’s long-term health.Smart DrillThe smart drill is a medical device that recommends how to drill and where to drill based on its calculations, the bone density, and the resistance encountered. It has a screen that displays real-time performance feedback. It helps surgeons get the right depth, the right number of screws to use, and the correct tightness.Ingestible SensorsA lot of people do not take their medicine as directed and this invention is here to change that. It involves pills that dissolve in the stomach and release a signal that can be picked up by a sensor worn by the patient. The sensor then automatically relays the data to a smartphone app and confirms that the user has taken their medication. The system has been trialed with antipsychotic medication, Type 2 diabetes medication, and other types of medication and has been proven effective. A company like Intellias produces similar products like wearable sensors that collect biometric data and vital signs.HealthPatchThis is a wearable patch with a bio-sensor that can be worn on the forearm. Under this structure, there are electrodes with axis accelerometers that detect and record the user’s temperature, heart rate, breathing rate, or sudden movements. It is used for monitoring patients as it can send an alarm once it detects any abnormal body position. The patch is also Bluetooth enabled and can send results to a connected smartphone or tablet for analysis. Instead of going from patient to patient and checking their vitals, this device does this on the doctor’s behalf.

Minimal buttons to avoid confusion.
Simple setup without the need for a smartphone or complex syncing.
A clear, backlit screen can also be beneficial, especially for users with vision impairments.
2. Accuracy: Reliable Step Counting

The primary function of a pedometer is to count steps accurately. Look for devices that use advanced sensors, such as tri-axis accelerometers, which provide more precise readings than older mechanical pedometers. Features to consider include:
Automatic stride length adjustment.
Error correction technology to minimize miscounts.
Ability to distinguish between real steps and accidental movements.
3. Wearability: Comfortable and Convenient Design

Seniors should choose a pedometer that is comfortable to wear and does not interfere with their daily activities. Common options include:
Clip-on pedometers, which attach to clothing and are easy to access.
Wrist-worn pedometers, which function similarly to fitness bands and provide additional comfort.
Pendant-style devices, ideal for those who prefer not to wear a wristband.
Ensure that the device is lightweight and has a durable build.
4. Battery Life: Long-Lasting and Low Maintenance
A pedometer with a long battery life minimizes the hassle of frequent charging. Consider:
Replaceable coin-cell batteries, which can last several months.
Rechargeable options with extended battery life of at least a week per charge.
Energy-efficient displays that extend battery duration.
5. Additional Health Tracking Features
Many modern pedometers offer extra health-related functions beneficial for seniors, such as:
Heart rate monitoring to keep track of cardiovascular health.
Calorie tracking to assist in weight management.
Distance measurement to provide insights into daily movement patterns.
Sedentary reminders to encourage regular activity throughout the day.
6. Connectivity: Syncing and Data Storage
Some seniors may prefer a pedometer that syncs with a smartphone app for detailed insights. Others might opt for a standalone device. Features to consider include:
Bluetooth connectivity for syncing with mobile devices.
Memory storage to track steps over several days.
Offline usability, ensuring that the device functions independently without needing a connection.
7. Durability: Strong Build and Water Resistance
A pedometer should be sturdy enough to withstand daily wear and tear. Consider devices that are:
Shock-resistant to survive accidental drops.
Water-resistant or splash-proof to handle exposure to sweat or light rain.
8. Price and Value for Money
Seniors should look for pedometers that offer the best balance between affordability and features. While basic models may be available for under $20, advanced options with additional tracking capabilities can range from $50 to $100.
9. Customer Reviews and Brand Reputation
When purchasing a pedometer, it is important to check:
User reviews, particularly from other seniors.
Brand reputation and customer service support.
Warranty policies, ensuring protection against defects.
