This time I present a retro-emulator on the Anlogic Chinese FPGA. The emulator has 8MB of 32-bit SDRAM embedded in FPGA. For communication with the keyboard, mouse, pad ... corresponds to the JDY-08 wireless module on the CC2541 chip which I programmed my own FW. FPGA configurations are loaded with 16MB flash on the board. The SD card is...[Read more]
![Photo booth for the party [Canon camera + Arduino]](https://obrazki.elektroda.pl/6452918600_1534333803_thumb.jpg "Photo booth for the party [Canon camera + Arduino]")
Several days before my wedding I came up with an idea to rent a photo booth for a wedding party. When I saw what the rental prices are, I quickly decided that I would do my own, because the cost of building it was close to the cost of renting a photo booth for 2-3 hours. By the way, I recorded some material for my YT channel ( JestemInzynieremPL...[Read more]
Construction description The tester was created to learn how to draw patterns in Eagle and learn the basics of microprocessor programming. In addition, it is small in size. I used SMD components for the first time. Scheme: PCB view from EAGLE: Here are the pictures of the finished structure: ...[Read more]
Hello. Before buying, it is worth checking what version we are dealing with. The point is whether the version is original or not. If we have non-original versions, after the update you will see the message: This board is Fake! This applies to the version with the serial number shown in the picture. Fortunately, there is an update...[Read more]
Module WEMOS D1 mini Pro based on ESP8266EX . A detailed description of how to integrate the module with Arduino environment can be found in the materials describing the modules previously made available: Amica and D1 mini. In addition to the configuration of the environment, you will find examples of digital ( DS18B20 ), and analog...[Read more]
Some time ago I successfully converted EPSON P50 into a printer that directly prints on the laminate. The effects were very satisfying for me, but the whole difficulty is to find an appropriate waterproof ink. I personally did not succeed in this, which is why I used the hybrid method (printing on an inkjet printer with "waterproof"inks, then...[Read more]
Some time ago I made myself a pure Class A headphone amplifier. I am not Audiofile, but in my opinion the structure works very nicely, the sound is dynamic and clear. Unfortunately, I don't have oscillograms, however the is no noise. Over time, the amplifier has developed a DAC that converts the signal from SPDIF into an analog...[Read more]
The tester automatically detects the type and layout of the lead leads of the connected component, and displays the measured parameters of the tested part. The tester is powered by 9V battery and during the measurement it draws current 12-15mA , while in sleep mode it draws current 20nA. Connect the test components to the three random...[Read more]
The assumption of the project was to create from the basics a programmer for popular Flash NAND type memory, to fill the gap in the market in the segment of low-budget programmers. Sometimes it is necessary to read the Flash NAND system located eg in a pendrive, but also various types of navigations, modems, routers, TV sets, etc. It is...[Read more]
DRF1278F Dorji. The Dorji Company has made available to users of forum elektroda.pl free of charge DRF1278F modules samples based on Lora Semtech SX1278 . DRF1278F modules were tested based on documentation, manufacturer sample source code and tests performed on modules DRF4463F last year. Modules PCB have a...[Read more]
![[Line Follower] Impact](https://obrazki.elektroda.pl/6945964700_1340750904_thumb.jpg "[Line Follower] Impact")
Introducing the Line Follower class robot named Impact. This is an improved version of previous design described in the largest forum of Polish amateur robotics. The robot was created in 2011, until now he was the winner of all competitions in which he participated. The biggest success is undoubtedly the first place in the international...[Read more]
Hello all. Unusual start the post from thank you. First of all, I would like to thank my friend Natalii , which using a gel pen she breathed life into this piece of electronics :) . Thanks are also due to colleague Radek, who served good advice during the design of the system. I also thank my mother, who negotiated good prices...[Read more]

Hello, I wanted to present a simple and proven (using the GLUCOFACTS Deluxe v3.05 program) cable to read data from the Bayer Contour TS glucometer. Of course, there is nothing extraordinary here, and his advantage lies in simplicity. For anyone who needs to archive measurements from time to time and has a computer with an...[Read more]
