I began experimenting with 3âD computer-aided design (CAD) on an old DOS machine that had a simple CAD program installed. Over the years I explored several toolsâPOVâRay for generative art, ZBrush for sculpting, TinkerCAD for basic modeling, and finally FreeCAD for more advanced Boolean operationsâand through these experiences built up my skills in 3âD design. The culmination of this learning journey is a wallet that I designed from scratch in FreeCAD and later refined in TinkerCAD; the prototype combines subtractions, Boolean operations, and an elastic locking mechanism inspired by Trayvax wallets, demonstrating both functional and artistic aspects of my first real CAD project.

The author argues that selfâtaught learningâespecially in fields such as astrophysics or medicineâproduces deeper understanding than rote test preparation, because universities reward grades over real knowledge and often ridicule independent learners; he cites the high rate of medical errors to illustrate how formal schooling can fail, and concludes that true education should integrate new concepts with existing ones and precede formal instruction.

The post argues that a variety of social problemsâpoverty, nuclear weapons, mass incarceration, police brutality, warâare âerrorsâ we must correct in the next generation and that our political system has done little to address them. It claims the root of many failures lies in âfake education,â where teachers teach disconnected facts instead of building on existing knowledge; real learning should be handsâon, analogical, and creative (e.g., using programming or generative art for math). The writer urges that students learn practical skills such as music composition, electronics, 3D modeling, and radio constructionâskills that prove intelligence in the spirit of Shostakâs radio testâand that schools should reward creation rather than grades. In short, the piece calls for a renewed, knowledgeâdriven education that equips youth to fix societal errors and contribute meaningfully to future generations.

The post argues that traditional schooling relies on grades and memorization rather than real learning, causing students to pretend theyâre learning for the sake of numbers. It suggests a new model where lessons begin with handsâon projectsâmusic compositions, art pieces, generative math programsâand end when pupils feel proud of their creations, not merely an exam score. The author envisions schools that let music lovers build synthesizers or 3Dâprinted sculptures, and art students produce large installations, while math is taught through programming and creative visualizations. In college the focus would shift from tuition fees to philosophy, science, and real problems such as nuclear weapons and poverty. Overall, the post claims selfâeducation with tangible milestones and creative output leads to true growth, better health, and lasting contributions, whereas the current system merely churns out âfakeâ education.

The post is an exhortation to young people that they must believe in themselves as âGeniusâ and actively pursue wisdom and greatness; it proposes creating a symbolic âpassportâ whose front bears the wordâŻEarth and which includes a credit card marked with a red heartâsymbolizing family, unity, and an abstract bank that guarantees food and freedom from debtâto be distributed to children alongside birth certificates. It links this device to a universal Bill of Rights, claiming that its full body can only be understood collectively but that a new generation can publish an initial version within a year. The text stresses that poverty must be eliminated before education so that minds can dream freely, and it calls on the current generation to unite the world through these symbols, correcting past mistakes such as those of the 1740 South Carolina Act and 1819 Virginia Code, while urging people to read philosophy, science, and leadership to become wise, great beings.

The author recounts the joy of hearing cicadas in NewâŻYork and then details their latest project: a compact RaspberryâPi MP3 player that can adjust playback speed for workout tempos while monitoring Bluetooth devices on Linux. They describe how they use simple code to handle device sleep, tune music tempo for three distinct workout speeds (140, 150, 160 BPM), and experiment with background noise and reverb in their song compositions. The post then turns to the physical case designâan aluminum enclosure built with CNC milling and 3âD printingâto house a small battery, custom buttons, and USB ports. Finally, they reflect on how this handsâon build has opened new learning pathways in electronics, software, and fabrication, illustrating their ongoing selfâeducation journey.

The author shares practical tips for painters who travel to find inspiration: bring a portable easel but plan ahead so you can set it up in the right spot; use photography as a reference rather than always riding out again; study color theory and replicate hues from source images; employ tracing, projection, and meticulous copying of shapes to build skill; and finally, remember that good art often comes after experimenting with different techniquesârules exist but are meant to be stretched.

The author reflects on his creative process by recounting how he writes three poemsâabout inspiration turning into wisdom, about meaningful education, and a metaâreflection on the first twoâand notes that even when he feels un-rhymed, the work steers itself. He describes the difficulty of finding visual inspiration for art, recalling a college incident where a naked model posed amid odd classroom details, which sparked an insight that inspiration often emerges from âlittle adventures.â He then narrates a personal stroll through a Plymouth bookstore, discovering Dan Millamâs *Peaceful Warrior*, which rekindled his affection for antiques and storytelling. From this experience he outlines how he would translate the scene into sketches and paintings, using everyday encounters to fuel creative output. In closing, he affirms that art requires only the spark that moves one to produce new works rather than a universal muse.

The post encourages painters to slow down and observe everyday colors, recording them in a journal so they can be recreated later; it stresses building color through transparent layers (especially in watercolor), avoiding arbitrary hues that add nothing, and selecting harmonious combinationsâlike purple & orange or gold & scarletâto give an artwork life. It suggests learning from established artists and even borrowing effective palettes as a shortcut, while encouraging the creation of small sketches to test these combos before committing them to larger works, ultimately guiding the artist toward mastery through observation, careful layering, and thoughtful color choice.

The post explains how to render graphite portraits: first locate the darkest parts of your image, work with midâtone pencils such as B or 2B, avoid hard strokes that damage paper, and keep indentations light so you can erase later; emphasize that shadows give a subject its soul, suggest photographing them in good natural light (sunrise/sunset), projecting the photo onto large paper with a pico projector, then sketching quickly while adding shadow details, adjusting gradients with erasers, and finishing by highlighting eyes and other key features; it also encourages using multiple angles, signing your work, practicing outdoors, and sharing tools to inspire others.

The author reflects on the fleeting nature of human achievementsâtrees cut down unnoticed and the fragile window in which we thriveâand urges that we use this time wisely by cultivating knowledge, courage, and dignity rather than merely chasing titles or wealth. He laments how poverty and misused money create climate, war, and hunger as symptoms of a system lacking true education, and proposes a âHeart Cardâ banking idea to simplify spending so people can focus on learning and solving systemic failures. In short, he calls for new generations to learn from past mistakes, understand the chain reactions behind global problems, and build a future where humanityâs wisdom and creativity guide its path rather than chance or poverty.

I built a DIY MP3 player by repurposing an old CDâROM drive as the chassis for a small PCB that plays preâconverted MOD files, and I attached a Bluetooth âshutterâ remote to control playback from my RaspberryâŻPi running Linux; after writing code that translates the shutterâs button sequences into simple shell commands (play, stop, shuffle), I can now operate the player with my phone, even routing its traffic through Piâhole for adâfree listening. The project has been a satisfying exercise in tinkering and learning, reflecting my frustration with oversimplified school curricula and my enthusiasm for openâsource hardware that lets me reprogram and extend devices without costly new PCBs.

The post argues that travelâwhether long adventures, short camping trips, or simple road journeysâoffers a vital escape from overwork and a chance to reconnect with oneâs own mind and hidden creative talents. It notes that while some people view travel skeptically, those who truly âtake to longer travelsâ often feel they are stepping away from themselves; the key is support and encouragement so they can find comfort and grow. The writer explains how overwork oversimplifies life and makes us miss beauty, yet traveling gives new perspectives and helps build personal constellations of ideas. Finally, he shares a personal anecdote: after reading Bill Brysonâs *A Short History of Nearly Everything*, he discovered a love for big books and science, and now wonders if he could write short stories; he encourages readers to take small stepsâcamping, listening to audiobooks, paintingâto become great beings.

Iâve spent several years in the United States and have seen a variety of wildlife that I never encountered back homeâpigeons, squirrels, sparrows, storks, deer, boars, rabbits, horses, cows, chickens, and now, American animals that feel more intelligent. My first U.S. sighting was a large possum that looked like an enormous rat but turned out to be sweet and tickâeating; I later met a skunk whose scent lingered long after the encounter. Iâve also seen a rare, big porcupine crossing a road near a store and photographed it, though only in blur. In the woods where black bears have been reintroduced, they usually stay away from people unless curious, whereas raccoons are constantly surprising meâonce stealing hotâdog buns at Jackpine HikeâIn Campgrounds (I dubbed the thief âFridayâ) and another time unzipping my tent at Nordhouse and leaving paw prints on my pillow. My advice to fellow adventurers: keep food out of tents, lock zippers, and be prepared for unexpected animal visits.

I built a minimalist portable Linux audio player that runs on battery power and an audio card without a screen or keyboard; I use a cheap Bluetooth âshutterâ remote (normally used for taking photos) as a makeshift button set to control play, stop, next/previous, and volume. After wiring the shutter to my device and writing basic input handling in Node.js, I plan to expand it with a phone UIâpotentially using Svelteâto stream audio or provide onâscreen feedback. The project illustrates how simple Bluetooth peripherals can turn a barebones Linux box into a pocket âserverâ capable of playing music, recording, making internet calls, and serving as a modular platform for future expansions.

I began my technical journey by tinkering with audio files in 1996, which led me to explore early DOS graphics programs like Image72 and the first Visual Basic releases, eventually mastering HTML through FrontPage and Photoshop for graphic design; this selfâpaced learning continued as I transitioned between jobsâfirst celebrating a 21st birthday at a bar, then diving into ASP, Perl (via FormMail), PHP, Bash, ActionScript, SQL, and Java before embracing Node.js to unify frontâend, backâend, and desktop development with Electron; alongside this tech evolution I returned to audio editing and poetry, experimenting with plosive sounds and pop filters, while also switching from Photoshop to GIMP for design work, all driven by a philosophy of uninterrupted selfâeducation that guided me from college (where I created my own classes in art) to a lifelong pursuit of knowledge without institutional limits.

Iâve been tinkering with a RaspberryâŻPi ZeroâŻW since I switched to Linux in 1998, and recently built a compact musicâplayer for my bike by powering the Pi from a 15âŻkâŻmAh Energizer power bank, streaming audio through an external USB SoundBLASTER card and headphones. After setting up ALSA so that `cvlc *.mp3` plays all my workout tracks on boot, I mounted the Pi, sound card, and power bank on the frame of my bicycle; the system runs headlessly in the background and resumes playback automatically when I reconnect to WiâFi after a 10âmile ride. The project has sparked ideas for adding a small keypad or wireless keyboard for control, a custom enclosure, and eventually a fully networked âBicycle Linux Serverâ that could be managed from my phone via Termux. This experiment illustrates how a modest Pi setup can become a portable media hub with minimal wiring and commandâline operation, while keeping the learning curve low and the hardware simple.

I learned how to make a RaspberryâŻPi button recently, and I researched it my way. [I wanted to see if there was a way to do it on the command line](https://simonprickett.dev/controlling-raspberry-pi-gpio-pins-from-bash-scripts-traffic-lights/) with the simplest kind of programming; there is. The [GPIO header](https://www.youtube.com/watch?v=6PuK9fh3aL8) is represented with files on a RaspberryâŻPi. I gave some thought to storeâbought devices as they relate to customâmade ones. I think storeâbought is not that cool anymore; in his funny song âThrift Shopâ Macklemore calls it *getting tricked by a business*, to say the least. Plus the moment you scratch your screen, your new device becomes old. If you made it yourself, then you just get a new $20 screen. And, hey, maybe add some [cool extras](https://shop.pimoroni.com/products/keybow-2040) while you're at it. YEEES! It is true that homemade hardware is freaking huge, and sometimes you may need your friend to carry your phone in his backpack. But that is what friends are for⌠I think. There is just something really weird about not knowing whatâs in your pocket versus whatâs in your storeâbought phone; criminal phone hacking will only become more elaborate. It has never been a good idea to keep personal things on an internetâconnected device. The phones are going to use cheaper components, become more expensive, and more closed. And it will pretend a lot harder that recommendations are not ads. When you make your own phone, you get to reason about the components; it seems to me that a GPS map should have a huge screen much bigger than a phone, and a bigger battery too. When you use an overpriced offâtheâshelf phone, you don't get a choice. Anytime you build something, you learn something: be it a reasonably sized RaspberryâŻPi Zero MP3 player with those amazing slow and soft turning aluminum knobs for volume, treble, and bass; or two or three 8GB RaspberryâŻPIs jammed into a [beautiful vintage brick phone](https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=vintage+brick+phone&_sacat=0) with a springy antenna that doubles as a WiâFi hotspot for your 1024 closest friends⌠and maybe runs a leaked version of old MySpace or Friendster, or just freaking [GeoCities](https://www.youtube.com/watch?v=9jYE8VwxunQ) where your whole family can come together and upload some underâconstruction content with fancy GIFs. Wouldnât it be amazing if all the telemarketers had to find their way around a little labyrinth and fight a *Freaking Grue* before they could leave a voicemail? I am pretty sure they would love it.

People often do not fight because they lack a clear cause and this ignorance is deliberately cultivated by the powerful; breaking the cycle of poverty requires real education and universal income, while a simple plastic creditâcard with a daily spending limitâlinked to a bank that does not track debt or fundsâcould eliminate poverty without adding national debt. By providing accessible money, such cards would lift people from hunger, reduce crime and suffering, and help businesses grow, thereby advancing humanity as a unified family that must remove all barriersâincluding ignorance and povertyâto achieve collective prosperity.
