Fresh hacks every day
Last week we saw a rotating iPhone dock built from Lego. This week we’re happy to put up another example of a dock made of these popular building blocks. Thank goodness this one takes into account all of the sudden jolts that our desk is prone to by incorporating shock absorbing springs. The design is very sleek with … Read the rest
The Cheap Vegetable Gardner wanted more automation than their previous PS2 controller based grow system. This time they set out to design a full featured, compact grow controller that can measure temperature and humidity as well as control a heat lamp, fan, and water pump. An Arduino provides USB connectivity and interfaces the solid state relays and sensors. The … Read the rest
[atduskgreg] posted this interesting setup to flickr. He’s using two toy cars as a switch. He has wired into their metal undercarriages so when they collide, the circuit closes. We’ve seen some pretty nifty home made interface items, but usually they are posted with a clear purpose or a project. This one is a little puzzling. Does he intend … Read the rest
This train layout is so small it nearly defies photography as much as it defies expectations. Built by model railroad enthusiast [David Smith], this is a model of a model: an N scale (1:160) layout inside a Z scale (1:220) world! For size reference, the entire layout is shown under a ballpoint pen tip in the photo above. And it … Read the rest
We’ve seen several creative projects from [Sprite_tm] and this one sets a new bar. He got his hands on some paint that changes color with temperature. By covering a circuit board with the paint then heating the circuits he’s created a heat actuated 7-segment display (his post is in Dutch). Three seconds at about 1 amp is enough to … Read the rest
The friendly robotic bartender we’ve covered a couple of times before hit the airwaves last week. [Jamie], the inventor of Bar2d2 sent in a link to video of the barkeeper in action. The story runs from 0:30-4:40 and covers a bit about the build, the conversion to automatic drink mixing, and plenty of happy liquor-guzzling party goers.
We get … Read the rest
We were a little surprised when we learned the Mazda RX7′s high beams were controlled by ECU, compared to typical cars using just a toggle switch. Ubermodder [Trent Bruce] realized how much of a pain in the rear end this can be if the ECU ever burns out, meaning no brights. By using a D-Flip Flop setup in a toggle … Read the rest
