In the late 2000s, a man begins relentlessly sharing his custom operating system, but when people take notice of the man's strange behavior, they become witness to the degradation of his mental state.

Quite possibly the dumbest project I've ever undertaken, this was an odyssey but well worth it in the end. It's hard to fully explain the depth of the rabbit hole that I was led down and I ended up having to study things like fluid dynamics, physics and chemistry. As the title suggests, this is a physically realistic (or at least, somewhat realistic) internal combustion engine simulation. It also generates audio which I feel is some of the best procedurally generated audio for a V8 engine I've ever heard.

DIY Perks basically builds a camera obscura.

3D printed speakers can sound so good!

Parts list: (Note that some links may earn me a commission if you purchase an item through them) It's approx $500 to build a pair (so $250 per speaker), which is good value when you think that a Sonos or Bose will set you back at least that much only instead of getting a single unit you get a stereo pair with better audio quality to boot!

Subwoofer: Tang Band W3-1876S USA: https://www.parts-express.com/Tang-Ba... EU: https://rkn3.net/c/?si=14570&li=16273...

Midtone Driver: Tang Band W3-1364SA USA: https://www.parts-express.com/Tang-Ba... EU: https://rkn3.net/c/?si=14570&li=16273...

Alternative mid drivers (these performed similarly and fit the enclosure): https://www.parts-express.com/Tang-Ba... https://www.parts-express.com/Tang-Ba...

Digital Signal Processor: https://ebay.us/i8U1fC

Amplifier: https://ebay.us/ZWlpBh

TWEETERS are optional, as the midtone driver + DSP sounds great on its own, but for the best quality a good budget tweeter is the SB Acoustics SB26STCN, which is my favourite overall due to its pricing, but a premium option is a Scanspeak D2608/913000 Tweeter. It has a bit more ‘sparkle’ and refinement, but this will ONLY be appreciated if the final speakers are given a signal from a high-quality output source like a dedicated DAC.

If you want to print the baffles, the recommended magnet size is 10mm diameter round neodymium magnets, with 5mm depth maximum.

Fixtures and fittings:

40pcs M3 threaded inserts (for the speaker drivers) 40pcs 3mm x 8mm countersunk m3 black screws (for the speaker drivers) 200pcs Self-tapping 2mm diameter screws, 10mm length max (build platform screws) 24pcs 3mm diameter self-tapping screws (amplifier screws, DSP chamber, midtone chamber base) 2x step-down voltage regulators, 5v output (for powering the DSP and fan) 2x 1000uf capacitor (add across the output of the regulator to reduce interference) 2x Power Adapters (100w ideally, each. A low cost option is old laptop power adapters) 1x roll of 16awg wire

Recommended glue is CT1 - it sticks to PLA well enough and doesn't set too quickly allowing the whole speaker to be screwed together before it begins to dry. This allows any spill over to be wiped away (use an old brush to get inside the air guide etc). Sets with some amout of flexibility. Readily availabe in the UK but not sure about equivalents for other territories. Visit the Forum or Discord server to see what the community recommends for each region.

SAFETY NOTES ON PLASTER OF PARIS: If you're stupid with it, it can be dangerous. NEVER put your hands/feet/whatever into plaster of paris EVER. It can suddenly set without warning, creating a lot of heat in the center, so you'll get burned or worse. Because of this never leave a batch of wet plaster of paris in reach of children or pets. Wearing a mask is recommended to not breathe in any dust, and goggles to stop it splashing into your eyes. Stay safe people!

Home built high precision air bearing CNC lathe and grinder having 1um (0.00004") accuracy.

Impressively robust for a DIY project.

This guy builds really brilliant miniature construction projects.

This is an incredible project developed by a guy somewhere in the world, It is an exact replica and working scale model of a Ferrari 312PB. Full engine and all, even a gearbox.

The entire pick and place series from beginning to end. The kid's enthusiasm is infectious and he is brilliant.

Today we're putting together a massive and very flat 7,000 pound welding table on a budget with some heavy duty supports to replace the less-than-ideal table I've been using to weld. We're going to put some of my favorite tools to use in the process, like my HYDMECH band saw and the beautiful American Pacemaker and Clausing Colchester lathes, so come along and enjoy the ride with us.

The Lockheed SR-71 "Blackbird" is a long-range, Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force. It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by Lockheed and its Skunk Works division. American aerospace engineer Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts. During aerial reconnaissance missions, the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch were detected, the standard evasive action was simply to accelerate and outfly the missile. The shape of the SR-71 was based on the A-12 which was one of the first aircraft to be designed with a reduced radar cross-section.

The SR-71 served with the U.S. Air Force from 1964 to 1998. A total of 32 aircraft were built; 12 were lost in accidents but none lost to enemy action. The SR-71 has been given several nicknames, including "Blackbird" and "Habu". Since 1976, it has held the world record for the fastest air-breathing manned aircraft, a record previously held by the related Lockheed YF-12.

I figured there is no more ambitious build than this feat of human engineering.

This Dwarf Fortress documentary details the development of the indie management simulation video game Dwarf Fortress and goes behind the scenes of its creation. Discover more about its two creators Tarn and Zach Adams. From a very young age, Tarn and Zach’s dad taught them the basics of coding and this led to the brothers creating about 400 games in the BASIC programming language. They were inspired by tabletop RPGs such as Dungeons & Dragons and Cyberpunk 2020, as well as many roguelike games from the eighties such as Hack, Rogue, Larn and Ragnarok. When Tarn and Zach were 12 and 14 respectively, they started developing their very first fantasy game that would eventually evolve into Dwarf Fortress.

The documentary also explores all the design decisions that Bay 12 Games made and shows why the project went from 3D graphics to using simple ASCII text-based graphics. It also takes a close look at all the hurdles the brothers had to go through. From struggling to become full-time indie developers, and Tarn’s bank account skimming zero multiple times, to completely overhauling the game’s world generation system during the process of adding a z-axis to Dwarf Fortress. Additionally, after Zach got skin cancer, the two developers started thinking more about their health insurance and how expensive it is. Therefore, they decided to partner with publisher Kitfox Games and develop a commercial version of Dwarf Fortress that was released on Steam and Itch.io in 2022. Lastly, the documentary takes a look at what’s next for the brothers, who are now millionaires, and their growing team and what we can expect of Dwarf Fortress in the future.
