Raspberry Pi Controlling an HCCI Engine

at 6:05 pm. Filed under Complex Hacks, Cool Gadgets, Electronic Hacks



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 thought that gasoline engines needed a spark plug. But like many things if you through enough tech at it you can overcome the issues. 

“The Pi is recording data about pressure in each of the engine’s cylinders, about the angle of the crank and about heat release – and on the back of that, it’s subsequently controlling the engine in real time over a controller area network”

Antarctica Arduino Instrument Cooling Project

  Antarctica Arduino Instrument Cooling Project_2


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 that. The dry air hinders the equipment shedding their heat as designed so a little bit of extra cooling is needed. Luckily cold air is always available, using a small pipe, cold air is sucked with a small fan into the equipment bay. The Arduino keeps track of how much cooling is needed and regulates everything automatically. The code is available but I am not sure how many people have a year round supply of cold air.

Remote Control Turned into an Oscilloscope

at 12:36 pm. Filed under Cool Gadgets, Electronic Hacks


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 remote comes with a 32 bit arm processor, on board flash, an RF transceiver with spi interface and a 128 X 160 pixel display

Goal Light and Horn Project

 Goal Light and Horn Project  


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 to allow it to activate automatically when your favorite team scores!

PCB Printer


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 makes prototyping a breeze

 Solder Paste Dispenser

Forget stencils. Pop your board in and dispense solder paste onto printed OR traditionally fabbed boards

 Reflow Capabilities

With a 550W heater watch your components reflow and skip the hassle of hand soldering altogether.”

 Nokia 3310 Phone Multimeter_2


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.
