I also needed a suitable hose system to build my solder fume extraction system. After a little trial and error, I decided to use the standard exhaust air hoses. These […]
Read moreI recently built an extraction system for my soldering station and the chamber of my 3D printer. The built extraction system has two connections. One of them sucks the air […]
Read moreThe 3D printed housing of the “pxlDigits” was initially not intended to be “just” a 7-segment display with WiFi. Originally I used it to build a kind of timer from […]
Read moreFor another project I urgently needed a relatively large number to indicate a duration. From this this small “sub-project” emerged. Because with the 3D printed frame described here and a […]
Read moreI started with the documentation of the pxlBlcks (which I had been postponed for a too long time) in November 2020 after Hackaday.com had announced the “GoodBye 2020” challenge. (More […]
Read moreActually not one of the typical articles for Nerdiy.de, but recently I was looking for a tambourine that I could operate myself while playing the guitar. Long story short: Everything […]
Read moreWhen looking for a foot rattle to accompany guitar playing, I had the same problem as with the foot tambourine. So again: do it yourself. 🙂 Instructions for building your […]
Read moreThe pxlBlck_RingClock is very similar to the pxlBlck_SlotClock. It is also built using a 1 × 60 LED matrix and can display the time according to the same scheme as […]
Read moreThe idea for the pxlBlck_Pot is heavily inspired by a design that Lukas (@i_am_lukas) had created. He agreed that I can use his basic design. Thanks again for that. 🙂 […]
Read moreThe pxlBlck_SlotClock consists of a 1×60 LED matrix. It can display the time in the same way as an analog clock. The colors of the individual hands can be adjusted. […]
Read moreThe pxlBlck plugin for the ESPEasy framework is the “software counterpart” to the pxlBlck platforms. With the plugin you can easily control the built-in LED matrices and with the help […]
Read moreWith the pxlBlck you can be informed about events in different ways. One of these possibilities is to be able to display previously set icons. Unfortunately, this option only works […]
Read moreThe adjustable dials differ from the type of LED matrix used. Unfortunately, this is the case because different LED-matrix sizes allow or do not allow different dials and screensavers. In […]
Read morepxlBlck is a system of hardware and software to set up an information system for the SmartHome. Various software and hardware options are available. Thanks to the integration in an […]
Read moreFor a camping trip I was looking for a cheap and bright fairy light. This should be waterproof and bright enough to illuminate the tent properly. It would be perfect […]
Read moreDuring the construction of a chain of lights, I was faced with the problem of how to get this chain of lights waterproof. Ultimately, I built the electronic components, which […]
Read moreA few days ago I posted the building instructions for a project of mine: WinDIY a 3D printed wind turbine. Even if I still have some work ahead of me, […]
Read moreOn a camping trip away from modern infrastructure, you quickly notice how much you have gotten used to the fact that electricity is somehow available anytime and anywhere. The stupid: […]
Read moreThe generator is held by a bracket in which a brake actuator is also integrated. In the following article you will find how you can proceed with its construction. Collect […]
Read moreSo that the construction articles for WinDIY do not become too extensive, I have divided the construction into several articles. A certain component such as the wing built. Of course, […]
Read moreThe WinDIY wind vane is mounted at the end of the device carrier. It should help to align the wind turbine always in the direction of the wind. How you […]
Read moreOne component that is supposed to make WinDIY more secure is the pitch actuator. It allows the wing’s angle of attack to be changed via a push rod. In case […]
Read moreThe turret supports the turbine and the superstructure on the standpipe so that it can be rotated 360°. A slip ring is also integrated in it to transfer the generated […]
Read moreThe main axis is the axis in which the wind turbine will later rotate. It must therefore bear the weight of the blades including the hub and at the same […]
Read moreAt one point or another I have probably already mentioned that it was important to me to be able to control WinDIY safely and to be able to limit its […]
Read moreAn important component of WinDIY are certainly the wings. They absorb the energy of the wind and convert it into a rotary motion, which in turn feeds the generator and […]
Read moreDear visitor of Nerdiy.de, I’ve decided to post a little update from time to time (probably four times a year) about what’s going on in the background on Nerdiy.de. This […]
Read moreWhenever possible I try to use finished nuts or thread inserts when using screws and the like. But sometimes there is simply no other way and you have to cut […]
Read moreSome may recognized in the Retro-speaker project, that it is a small hobby of me to give old things a new benefit. If you can also improve the old technology […]
Read moreAt some point last year I stumbled on Ebay on the very cheap TDA7492/CSR8635 Bluetooth amplifier boards. These include a Bluetooth audio receiver and a stereo amplifier with which speakers […]
