To set the scope of what I am and am not going to talk about here:I am going to describe the pinouts on the IVL2-7/5I am going to talk more about what I did to get it workingI am going to talk about how to test your VFD to make sure it behaves as you...
The monitor shows the daily routines of one month, but stores the entire year. When the routine is accomplished, just press the corresponding day button. This changes the LED light on the button from white to green. I picked the colors green and white,...
Trawling eBay netted a reasonably inexpensive Accuthermo FC100D TEC (Peltier thermo-electric cooler) controller mounted in an enclosure from Wells-CTI with a 12VDC 8A power supply and TEC H-bridge driver. The FC100D uses PWM and bi-directional...
What is the aim? This log is all about: How can we make the whole board cheaper while keeping all the features and not killing its safety functions. This all refers to the early v0.2 version which is by no means optimized yet! Ways to cut costs I try...
Motor controller and current measurement This will be a long log, so I want to summarize: The motor controller of the “single board” works as expected and we can get a current measurement which is good enough to detect blocked or damaged...
Composite video standard defines a signal with 1Vpp amplitude under a 75 Ohms. From that signal 70% (0.7V) is the amplitude of video information which stands above a 0.3V pedestal, while the synchronism information (sync tip) corresponds to the remaining...
Intro Soft robotics is a field that has fascinated me for the longest time. Though the research field is maturing, I still haven't seen many hobby level soft robotic projects. Starting with no prior experience, a little more than a year ago I got to...
Welcome to the Solar Genius Page Introduction Energy is one of the necessities to live on this planet. Plants use energy to prepare their food, humans use energy to cook their food, and industries use energy to manufacture different...
So you want to build your own keyboard (or keyboard-like device), but you are not sure what to use for the brains and how to connect and program it? I will describe what I came up with for the #Alpen Clack keyboard.The ATmega32u4 microcontroller is an...
Well it's a good thing I wasn't relying upon Mr. Gibbs to navigate the ocean! The system had some issues, to say the least. The bad news is I didn't get to gather any usable data over the weekend, and we did not actually get to use the system at all....
My lab partner, Andrew, and I were faced with deciding on a senior design project to complete our degrees at Lehigh University. Not wanting to waste an opportunity (possibly my last) to work with someone as smart as Andrew, I wanted to take on an ambitious...
The experiments with the RES64 are on hold, waiting for the delivery of more/new parts (and the strikes in France make the delivery date even more uncertain) so I'm back to the ASIC side of the projet. There is significant progress with #VHDL library...
Extract the contents of the files. Copy the nRF905 library file to the Arduino library location.Open the project file for Rover using Arduino IDE. This contains the code for the Arduino Uno in the rover car.You can check and modify the transceiver...
Okay, initial thoughts. As a first cut I want a program that will play a random piano note, so that I can try to find that note on the piano. Basically, I'm tuning my ear to be able to recognize piano notes by pitch. I frequently can "hear"...
The second round of performance testing with this device shows promising results. The main change to the system since the last round of tests is that the built-in 65 degC thermostat has been removed from the silicone pad heaters. The thermostat...
