 This HCCI Engine Controlling Raspberry Pi setup reads in 240,000 samples per second. I had never heard of an Homogeneous charge compression ignition (HCCI) engine other than a diesel that simply compressed the air fuel mixture till combustion although I guess that is what some of those cars from the 80 were doing when they would continue to run after the key was turned off? I had always
 If you thought the Arduino was just for DIY projects have a look at this Antarctica Arduino Instrument Cooling Project. Isn’t it strange that in a place that only ever warms up to -25C that you would need to ever worry about keeping equipment cool? Well the issue is that the equipment is in an area with people and we like to have things a bit warmer than
What happens when a remote control manufacturer makes their hardware robust and easy to hack? It gets turned into an Oscilloscope! Check out the Betty Check – Betty Remote control turned into a multi function electronic tester. If you are have one of these remotes and need some additional information to modify it have a look at this page, it demonstrates much of the hardware in great detail. The
  JLocke from the Parallax Forum put together this interesting Goal Light and Horn Project that should be a big hit with sports fans. With the press of a button you will get a celebration light and some audio of your choice. Love the industrial look of the project. The custom PCB looks nicely laid out!  I am thinking the next logical step is to make this project web connected
 The prize this week is a wireless transmitter for your next project. This contest will run for one week (Jan 11- 16, 2015). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Don’t need a make or model, just what what the thing is used for. Please do not give the answer in the comments. Send
You thought that the new ease of getting cheap prototype PCBs made from companies like Seeed was revolutionary, how about a cheap machine that can allow you to print it at home? Looks like Voltera could help speed up prototyping (at least for SMD boards). Via: Adafruit and Make “Circuit Board Printer Print dual layer PCBs on FR4 with 10mil space/trace. Our 20mΩ/sq sheet resistance and conventional soldering
 If you thought your old phone in your junk drawer was just good for making calls think again. Check out this Nokia 3310 Phone Multimeter that Mastro Gippo built! It does graphing of voltage and currents, has an ohmmeter and a continuity tester. There are also a ton of other fun features that should have been in place on this phone when it was originally released.Â
