Compressed Air Engine

Who knew that 3D printed parts could be made to such tight tolerances! I'm very new to experimenting with ABS acetone smoothing, so this was a great project to start with!\n\n3D Printer settings:\nNozzle diameter - 0.2mm\nFilament diameter - 1.75mm\nExtrusion width - 0.25mm\nLayer height - 0.1mm\nTop solid layers - 6\nBottom solid layers - 6\nSide walls - 6\nOutline direction - Outside-In\nInfill - 25% (honeycomb)\nMaterial - ABS\nNozzle temperature - 240C\nBed temperature - 60C\nCooling - OFF\nPrinting speed - 1800mm/minute (Correction from video)\n\nOther parts required:\n1pcs Spring (outside dia: 3.18mm, free length: 12.7mm, wire dia: 0.51mm)\n1pcs M4x30mm bolt (this can be any desired length)\n3pcs M2x20mm bolts\n1pc M2x bolt\n2pcs 604-ZZ bearings\n2pcs 3mm brass collars (these can be cut from brass tubing with inside diameter of 2mm and outside diameter of 3mm)\n8mm inside diameter PVC tubing (for air supply)\n\nA propeller of some sort will also be required, probably something around 5-8 inches in diameter will do the job.\n\n\nDisclaimer: If you wish you 3D print this engine, do so at your own risk. Working with high pressure air is DANGEROUS and I hold no responsibility for your actions. All parts were printed to the highest strength possible and I can't guarantee that your parts will be the same. So please test the engine behind a protective cover and only to low pressures below 30psi.\n\nSponsored by 3D Printz UK: https://3dprintz.co.uk/\n\n----------------------------------------------------------------------------------------------------------------------------------------\nWant to promote your company or product?

Floating Death Star

I made this as a Christmas present for a relative. It is a cross between a floating globe of the earth, a Disney Death Star mood lamp, with some added electronics.

Inside a 22mm digital panel indicator/voltmeter.

This is neat, and surprisingly cheap too. Instead of just being a panel indicator light it also displays the supply voltage. That's a very nice solution for quick diagnostics. The quality of construction seems OK. Very simple and well rated components for standard mains voltages, although the sense resistor may not be rated for the higher phase to phase voltages.\nPower dissipation is low at about half a watt with predictably poor power factor (0.07) because of the simple capacitive dropper and low circuit voltage. There's no significant heat being dissipated on the PCB.\n\nThe music track referenced is an old fairground classic called Dominator:-\nhttps://www.youtube.com/watch?v=-dohzrXT09w\nCarl Cox mix:-\nhttps://www.youtube.com/watch?v=iYvrXtmrLSY\n\nHere's a universal ebay search link for the meters:-\nhttps://www.ebay.com/sch/i.html?_from=R40&_sacat=0&LH_BIN=1&_nkw=22mm+voltmeter&_sop=15\n\nIf you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-\nhttp://www.bigclive.com/coffee.htm\nThis also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

Lost in Light II

instagram.com/sriram_murali\n\nLost in Light II is a short film showing how light pollution affects the view of the night skies using one of the most prominent constellations - The Orion. The success and reach of my previous film(youtu.be/j2hNaT56FUY) - made the news in over 40 countries and published on National Geographic, inspired me to make a follow up to help people even better relate to night skies and further raise awareness on light pollution.\n\nOne thing I realized from my last film was that people were able to relate to the difference between the light pollution levels but not the Milky Way itself. The Milky Way appears more colorful to a camera than it does to our eyes and most people haven’t seen it. But, the Orion is a more common sight. It’s a great subject to help explain light pollution.\n\nAstronomy is a humbling and character building experience like Carl Sagan puts it. Being under a sky full of stars makes you feel tiny, humble, kind and caring. But, thanks to light pollution, most people lack this connection. Millions of kids are robbed of finding their passion for Astronomy. We've lost the potential for thousands of great minds. We are losing our identity only increasing the difference between us.\n\nIn less than hundred years, we have drastically altered our night time environment. Light pollution affects our health, disrupts our sleep patterns, increases the risk of cancer, diabetes, hormonal disorders and other diseases. Millions of birds are killed each year colliding into brightly lit buildings. Baby sea turtles(hatchlings) are often confused by bright lights and never make it to the sea. And we've only begun to understand the effects. But, fortunately, there are ways to fix it.\n\nThe International Dark Sky Association recommends using shielded lighting, low color temperature LEDs(2700K and less), motion sensors for safety than leaving lights on all night. Unshielded bright LEDs create a lot of glare and impairs vision. Several cities and municipalities have recently switched to dark sky friendly lighting and people are welcoming the change - they’ve hardly noticed any difference in lighting and in fact, hated harsh bright lights. Tucson, Phoenix, Montreal, the state of Georgia are all examples. It makes me really happy and optimistic hearing these success stories. Fighting light pollution does not mean turning all your lights off, it’s about being wise with our lighting choices.\n\nWhat can we do ourselves? Start by inspecting the lighting in our homes. Home Depot has a separate section for dark sky friendly lighting. Then, look for bright unshielded lights on nearby streets, parking lots, etc. Raise awareness on the issue, get help from the IDA to make your city write lighting ordinances. Together, we can fight pollution and have our night skies and our identity back.\n\nContact: srirammurali.com/contact/\nMusic: Imagine by Ryan Taubert\nCopyright All Rights Reserved

Casually Laser-Exposing 0.2 mm PCB features on a 3D printer

Cetus3D printer: https://www.cetus3d.com/\nLaser module: https://goo.gl/sb2m4k\nMy patreon: https://www.patreon.com/marcoreps\n\nHolder .stl file: https://drive.google.com/open?id=19XB8ktrIu9sGUK21tpFv_AmdhW9SvtCa\n\nTest layout Eagle .brd file: https://drive.google.com/file/d/1sE2sykS5GtyzU_qfyVLJ0WTsiXXSR3PW/view?usp=sharing\n\nIn this video I wanted to make a heated build platform for my cheap 3D printer, but got distracted by another interesting feature of the Cetus. It has an unused output on the print head, that can be controlled from within gcode. That opens up a ton of possibilities, but what I am most interested in is, as always, laser PCB prototyping. Will that work? Spoiler: Yes, it will. Incredibly well.

Action Cam Footage From October 2017 Spacewalk

NASA astronaut Randy Bresnik captured this footage with a GoPro camera on Oct. 20, 2017 during a spacewalk outside the International Space Station. Bresnik reflected on this quiet moment, Sometimes on a #spacewalk, you just have to take a moment to enjoy the beauty of our planet Earth. This Go-Pro footage is from our spacewalk where Joe Acaba and I refurbished the Canadarm2 robotic arm and the Dextre robotic arm extension. \nRead more about the spacewalk: https://blogs.nasa.gov/spacestation/2017/10/20/expedition-53-spacewalk-successfully-comes-to-an-end/\nFollow Randy Bresnik: https://twitter.com/astrokomrade\nhttps://www.facebook.com/AstroKomrade/\nhttps://www.instagram.com/astrokomrade/

Map of Biology

Biology is the subject that studies life in all its forms, from the simple cell through to all the animals that inhabit the planet. In this map I lay out the subject of biology and how all of the sub-disciplines are related to each other: microbiology, genetics, bioengineering, anatomy, physiology, medicine, neuroscience, ecology, zoology to name but a few.\n\nBiology spans the scales, from biophysics and biochemistry studying the basic elements of life, to the study of whole ecosystems and the environment. If there is one word that describes biology, it is complexity. There is a huge amount we still don’t understand about how life works, how it started and how it ended up with us.\n\nPOSTERS: If you would like to buy a poster of this map, they are available here: https://www.redbubble.com/people/dominicwalliman\n \nI have also made a version available for educational use which you can find here: https://www.flickr.com/photos/95869671@N08/?\n\nThanks so much to my supporters on Patreon.
