More than often enough parts of projects will have to communicate with each other or external devices. This can either be done by directly connecting the devices with cables but sometimes it’s more convenient to wirelessly connect the different pieces of hardware. This article will show you how to use the ESP8266 and it also includes two examples for using it with a Raspberry Pi and Arduino boards.Continue reading How to use the ESP8266 for wireless communication
Some Arduino boards have a built-in EEPROM that can be written to and read from in your programs. I not only want to discuss how that’s possible but I also want to show you an alternative while talking about EEPROMs and memory in general.Continue reading How to use an EEPROM to permanently store data with your Arduino
I enjoy building these kits and so I thought that it was time for season 2 of the banggood stuff webseries. This episode covers a 15$ oscilloscope kit you have to assemble yourself:Continue reading Banggood stuff – Season 2
In the third part of this series, I want to talk about the PCB design and the custom case for the electronics. I’ll also revisit the transistor array, which I didn’t finish in part 1 of this series and I test the completed project and show it in action.Continue reading Nixie tube thermometer – Part 3
Note: An updated version of this article is available here! However, this article remains valid and I placed a note in every section that got updated.
It’s been a while since I published this series of articles on nerdhut about monochrome video signals for an old Macintosh CRT. I wanted to post a short follow-up article about VGA and how to generate such signals. This article will also be a follow up to the custom CPU series and it will be another step towards the custom computer, I always wanted to design and build.
However, in this article, I only want to take a look at how the standard 640×480@60Hz VGA-Signal can be created using a screen testing device, made from discrete electronic components, which can be used to test monitors without the need of a computer being around. Continue reading VGA signal generation using discrete electronic components
In this part of the series I’ll discuss how to read data from the temperature sensor, make the Arduino react to claps and I’ll also go over the software that controls all these features and then displays the right numbers on the Nixie tube display. Continue reading Nixie tube thermometer – Part 2
Years ago I bought a bunch of IN-14 Nixie tubes from the Ukraine and I had them lying around since then. I always wanted to use them for a custom device and so I decided to finally tackle this project and build something that utilizes this almost ancient way of displaying digits, but for now I didn’t want to build a Nixie tube clock (I thought that was a bit of a cliché thing to do and for now I’ve had enough of fancy hipster clock projects), so I thought: Why not build a thermometer for my room that can be activated by clapping?
