Fresh hacks every day
We see a lot of video game tech coming out of the three console giants (Microsoft, Sony, and Nintendo). With one look we can usually predict what is going to be a flop. Case and point is the Wii U whose sales have been less than extraordinary and Sony Move which is motion control directed as hardcore games who we believe are perfectly happy with the current evolution of their dual shock … [Read more...]
Projector bulbs can be incredibly expensive to replace. Sometimes it's more cost efficient to just buy a whole new projector instead of a new bulb. [Shawn] recently found a nice deal on an 'as is' Epson EMP-S4 on eBay and decided to take a chance. He assumed it probably worked with the exception of the missing lamp the seller mentioned. His suspicions were correct, and one custom LED mod later, … [Read more...]
Giant fresnel lens is dangerous fun Here's an interesting, and rather dangerous, use for those old big screen TVs that are frequently listed for FREE on Craigslist. With the lens from the old TV built into an adjustable wooden frame, [Grant] was able to melt a stack of pennies, instantly burn wood, melt spots in concrete, and serve his family a cooked egg... Cool. Projection mapping app helps … [Read more...]
[Rachel Levine] was one of the mechanical engineers on the team at the Rochester Institute of Technology who built this resin-based 3D printer. She wrote in to show off the fantastic work they've been doing. Their project website is daunting to take in at first, which shouldn't be all that surprising since the concepts used here are fairly advanced. But give yourself a few minutes of blind … [Read more...]
[Chipsy] found himself with an interesting problem. The room that serves his home theater has a wall mirror which reflects part of the screen during viewing. In an otherwise dark room this was very distracting. His solution was to add a blind that covers the mirror during viewing, but who wants to constantly pull that down and back up again? Since the motorized projection screen he is using has a … [Read more...]
[Lou] needed to mount his projector to finish up his home theater. But he was rather put off by the cost of commercial solutions. He ended up building his own projector mount for about ten bucks. The technique reuses some scrap metal and sources connectors from the hardware store. If your projector will be mounted flat to the ceiling we think this will work just as well for you as it did for … [Read more...]
[Michiel] gave us a little shout-out by drawing the Hackaday logo with his recently completed 16x8 pixel laser projector. It uses a spinning set of mirrors mounted at slightly different angles to redirect the path of the red laser diode. The projector is driven by an Arduino. To give it more than just a hard-coded existence [Michiel] included an Xbee module. This lets him connect to it with a … [Read more...]
