The work by others to port Arduino BASIC to the Smart Response-XE device was of interest, but I wanted a few enhancements to extend battery life (auto shutdown) and I wanted an easier way to do math on the console rather than typing "PRINT" everytime...
IntroductionI've owned a MicroKim by BrielComputers for years, but it had been defective for a long time: as it turned out, the EPROM was malfunctioning. This project describes how I found out what the problem was, and how I fixed it. And hopefully it...
Turing Machines 101 The Turing machine was invented in 1936 by Alan Turing. By providing a mathematical description of a very simple device capable of arbitrary computations, he was able to prove the properties of computation in general. A...
Wheel of The Year On 16 segment Display The wheel of the year is divided in 8 intervals, and the corresponding segment is lit whenever the current day is inside the interval. In the picture below, the segment will be lit from February 1st until March...
Ok, first of all an important mention goes out to Edderic Ugaddan (twitter @eddericu ) who is currently making and selling a cool device called the Laminair. It's his research that showed me that this kind of device was valuable, because he has...
Another clock? There is nothing particularly special about this clock, except perhaps that is is built from a 8042 microcontroller chip (henceforth MCU) salvaged from a very old PC. The most modern component is the integrated serial display which...
The selection of the feedback resistors is critical. The standard output voltage is supposed to be 3.3V. For the appropriate resistor values i just checked the datasheet which had a table with values. Since the I want to be able to select the output...
I made many projects regarding Audio amplifiers and preamplifiers but this tutorial is for the visual music experience. I am going to make a music reactive neopixel based LED strip. The LEDs will glow according to the change in beat and the color is...
The memory systems of Altera Cyclone5 FPGAs have various features and limitations. I will not talk about the HPS side here, only the FPGA side. Memory systems include:M10K blocks on Cyclone5 SE A5 There are about 390 blocks, each capable of holding:...
Ultradian Rhythms The conventional workday was designed to keep people busy during the whole working period, assuming that they can be productive the entire time, but as we all know that simply doesn't happen because our bodies are chemical engines that...
Project choices and the mission As stated in the summary, my goal is to provide an open solution to the bipedal walking problem, in order to give others a starting point and source of inspiration. This includes hardware designs, drawings, assembly plans,...
What you will learn here: Circuit design of small board layout with minimum electronics componentsCircuit assemblyProgramming through ISP and test the complete made device Let's GO! Supplies The required ingredients for producing the earring are as follows:...
* * PREFACE * * Luckily I have enough electronic stuff "to survive" these days, so I decided to start the design of a new "retro" board, this time using a V20HL CPU. Of course my way... * * THE PROTOTYPE * * In the first phase of the design I've used...
This is the total schematic. I've experienced wonderful sound quality of TPA3110, class-D amplifier at Nutube amplifier and it is transferred to happy amp. The performance of TPA3110 is max 15W x 2 and I can guarantee its sound quality!The input line...
The SMT50 MachineThe guy that sold me the machine agreed to build a suitable shipping crate around it. Normally one would anchor an 80 lb machine to the bottom of the crate with bolts going through the crate frame and the base of the unit. Nope. It was...
