Fresh hacks every day
RGB just got a lot brighter by using 3x60Watt flood lights instead of an LED. The bulbs are driven via TRIACs and the whole thing uses a remote control to change the levels of the three bulbs. It is also able to store these levels for later recall. The IR receiver was taken from a dead TV set along with its remote control, or a universal remote set to a Phillips TV can be used. The source code and … [Read more...]
This IR receiver based on ATtiny13 microcontroller is used to control a Media Center box via a remote. The circuit is powered by 20 pin ATX connector pin 9 "+5VSB" because it is the only pin that is powered when the computer is off, or in standby. The receiver is programmed to accept the codes from the remote by holding down the switch while pressing the remote button. The circuit can use "Girder" … [Read more...]
This vertical axis wind turbine (VAWT) uses five 3” PVC pipes cut in half for blades rotating on three kids bicycle wheels to spin an Ametek 38 volt motor or a wind blue alternator. The whole thing spins in a frame that is a 12 feet high and 2 foot square box that is able to sit on his deck. In total it cost him about $125 plus time, a bit more if you use the wind blue alternator. Video of … [Read more...]
[Albert] read the Cisco PIX Wiki, and discovered that the motherboard of the PIX 506E is the same as the PIX 525, which has a 600Mhz Coppermine Pentium III CPU. So he took his Cisco PIX 506E and upgraded it by swapping out the Celeron 300Mhz, with a Pentium III 600Mhz and populating the second PC100 RAM slot inside. The system only shows 448Mhz instead of 600Mhz, but it does recognize the PIII, … [Read more...]
This project provides LED feedback when an email is received. It uses a 4d-micro-USB module from Dontronics to interface serially and provide power to a Picaxe 08M. The PIC can control color and brightness of a RGB LED. The feedback is given by seven colors of the LED. The code is python script and picaxe basic, which he's posted. … [Read more...]
