Fresh hacks every day
As a boy scout properly acculturated into the DIY philosophy, [Adam] really wanted to get his hands on the new Inventing merit badge. The merit badge required solving a problem, so of course a pinewood derby instant replay system was the obvious solution. After thinking through a few solution paths like a radio-controlled camera that follows the cars, [Adam] settled on a system that would … [Read more...]
Here's an image of a bullet's path to the target. There's a couple of things to note. First of all, this is not a tracer round, the projectile actually has an LED incorporated which was picked up as a trail in the long (relative to bullet speed) exposure. The second - and most obvious - thing to consider is the non-liner path it took to its objective. That's because this is a laser guided … [Read more...]
[Fall Deaf] built an Arduino based universal remote control system. It uses a shield which has both an IR receiver and transmitter. This gives it the tools to learn codes from your existing remotes and play them back in order to control the devices. This functionality is really nothing new, but we think the user interface he developed for the system is absolutely fantastic! Software is … [Read more...]
This lens adapter makes a lot of sense if you're looking to interface with cameras that don't have an in-built mounting option. It uses the cap and threaded neck from a soda bottle (translated) to make the lens adjustable and removable. In the past we've seen this hack using a lens cap with a hole drilled in it as the mounting bracket. But that's only useful if the lens you've chosen actually … [Read more...]
[Udo Klein] was working with some 1N4148 transistors and was interested in the specs relating to their performance at different temperatures. The forward voltage actually changes quite a bit depending on temperature and wondered if this could be reliably measured. He hacked his own LED shield for the Arduino to use as a 1x20 thermal imaging system. The screenshot above is mapping the voltage … [Read more...]
The only thing he needs now is a micro and RTC For [Dino]'s 44th Hack A Week extravaganza, he made powered window blinds in five minutes. It's a simple build with a small gear motor and a bit of tubing to adapt the shaft to the control rod of the blinds. Good job [Dino]. BecauseCamelCaseWillKillYourPinkieFinger The wonderful [Lizzie] over at LUSTlab realized that typing meta keys … [Read more...]
[Joel] of [Helion Microsystems] is at it again with his USB controlled solder reflow oven. You may remember him from his crazy twitter-enabled Ewok model. Although these two projects are quite different, they both use the HU-320 USB breakout board that he's in the process of getting funding for via [Pozible], or Australian Kickstarter for Yanks. The reflow oven works using a … [Read more...]
