mutantC is a Raspberry Pi UMPC. An open platform device to use any serious professional work and create your ecosystem of automation. It is fully Open-Source hardware. So you can hack it as you wish. Make your expansion-card like GPS, Radio etc and attach them. You can access all the ports of the Pi. The back part is attached with 4 screws. It can hold a 4" or 3.5" touch screen. Also have a 52 button physical keyboard. It doesn't need any custom OS, you can use plain Raspberry Pi OS and install the LCD driver, that's it. So little parts needed to make one. The priciest thing is the LCD and Pi.Please shear the link to all your friends .Project LinksYouTube Project Website Discord Matrix TwitterBuild Guide1. Order the parts from online, here is the full Parts list.2. Order the 3D printed parts, you need to print 4 parts, here is the parts files. You can Order them from PCBWay 3D printing service.3. Order the PCBs, there is 3 PCB you need, here is the files you need to order. You can also order the PCBs from PCBWay PCB prototype service. That way you can get the 3D parts and PCB fast within minimum days and save shipping costs.Now solder the parts and flash the firmware from here. Now flash a SD card with Raspberry Pi OS and install the LCD driver from the place you brought the LCD module.That's it you got your fully working mutantC v4. If you want to try out some Expansion Boards you can see some of them from here, there is 6 of them currently.https://www.youtube.com/channel/UCbU1bjAwaDnZZvXIBHzUXuQhttps://discord.gg/9nHn6YNr

WIFI controlled drone V4: This is the project of making the cheaper drones for swarm, it is controlled via WIFI so we can connect lot of drones via WIFI and controller then with IP address. It has only esp8266 12f microcontroller it will reduce the cost lot. version 1: https://youtu.be/ytPcFnzOIw0version2: https://youtu.be/inXrJhFHnBoversion3: https://youtu.be/Njx4hY6HOwgchoose 1.2mm PCB thicknesseven after lot of crash the 1.2mm doesn't break ,I will recommend 1.2mm thickness.Thanks to PCBWay for making project successful !!!

Dimmer capable of working with low power loads, with capacities for external control such as an Esp8266, RPi

The board was created on the basis of a project by a famous Russian blogger.

LoRa or Long Range wireless data telemetry is a technology pioneered by Semtech that operates at a lower frequency than NRF24L01 (433 MHz, 868 MHz or 916 MHz agains 2.4 GHz for the NRF24L01) but at thrice the distance (from 3000m to 8000m).You can find E32 here AliExpress (433MHz 3Km) - AliExpress (433MHz 8Km) - AliExpress (868MHz 3Km) - AliExpress (868MHz 8Km) - AliExpress (915MHz 3Km) - AliExpress (915MHz 8Km)You can find here AliExpress (433MHz 4Km) - AliExpress (433MHz 10Km)You can find the adapter for SMD modules on We are going to test E32-TTL-100 and E22. E32It is a wireless transceiver module, operates at 410 441 MHz based on original RFIC SX1278 from SEMTECH, transparent transmission is available, TTL level. The module adopts LORA spread spectrum technology.The module features FEC Forward Error Correction algorithm, which ensure its high coding efficiency & good correction performance. In the case of sudden interference, it can correct the interfered data packets automatically, so that the reliability and transmission range are improved correspondingly. But without FEC, those da te packets can only be dropped.And with the rigorous encryption & decryption, data interception becomes pointless. The function of data compression can decrease the transmission time & probability of being interference, while improving the reliability & transmission efficiency.E22It is a wireless transceiver module, operates at 410 493 MHz based on original RFIC SX1268 from SEMTECH, transparent transmission is available, TTL level.

This project is a wifi controller for large scale garden railway locomotives. It uses a ESP32 microcontroller to generate a webpage so you can control your loco on from your smartphone, or tablet. This provides and cheaper entry into battery control by not having to purchase a separate transmitter. And of course you are welcome to modify the code for your own scenario.A more complete documentation of this project is on my GitHub page with the source code.Please check the Arduino Sketch for the ESP code: https://github.com/nygma2004/locoremoteAlso have a look at my prototype video where I talk about the features of this controller: https://youtu.be/NFEwV57PYEw

The original ISPINDEL PCB is CHERRYPHILIPYou can find instructions, video tutorials on youtube (key search iSpindel). THANKS ALL USERS for that.The cherryphilip 4.1 PCB for the iSpindel, few minor improvements introducing on this version. Here main features:On the front , I moved of few mm the thermal sensor device outside battery area. To avoid possible short circuit due to pins that could touch the body of battery or ti have fake measurements.On the bottom edge there is a change as well. I indroduced a specific form just to touch the bottom petling.During the design i used a Sansung 30Q battery with 48gr weitght incorporates a fixeble battery holder allowing you to have your iSpindel to 25° degrees in pure water. However, there are some battery with different weights that can changes the final balance. No worries, iSpindel works fine with balance between 20° to 30°Sincerely,cherryphilip
