mutantc V4 - DIY Handheld for your professional worksmutantC 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.

Already made Mosfet Driver Board for easy pwm out out interface.EASY to use with Arduino inverter, SG325 IC BASED inverter systems,etc

After using the Microchip tools to program and debug the projects I work on, I wondered about creating my own programming/debugging module that I could put on my own boards – just like Microchip does with their starter kits and such. As I became more interested in that idea, I began to search the web to see if anyone else had already done something similar. Initially, I found lots of posts regarding the 2nd version of the Pickit – the Pickit 2, but not as much regarding the latest version – the Pickit 3 – which is what I need to program the 32 bit pic processors that I am using. After a while I came across a post – From this blogThis Individual had created his own version of the Pickit 3 and had posted his method for doing so. I was excited to see some real information about the process, and set about determining how I would do the same, now that I knew someone else had verified that it would work.The version that was built on the blog linked above, was done so on a protoboard using a variety of components, and was completely hand-wired. As impressive as that is, I was looking for something a bit sleeker – especially since I was looking at some point to modularize it and use it on other designs. I decided that I would design my project to use surface mount components and a purpose designed PCB. With that in mind, I set out to create my schematic. After looking at the one from Hendrik’s blog post above, and also studying the actual Microchip pickit 3 schematics that are publicly available in the documents released by Microchip, I came up with the following schematic. It is pictured below, and here is a link to the full-sized PDF: My SchematicActually, I did address it. In the section where I go over the areas on the schematic, I indicate one of the programming headers is used to load the pickit 3 code into the pic24 chip. Later, at the bottom of the article, I indicated that I was not hosting the HEX file that Microchip provides, but it can be easily found looking in the directories that are installed with the Microchip IPE application. (Or – online in several other locations…Google is your friend). Of course you will also need a programming device to program this device initially. I used a pickit 3 that I already had access to. Now I just use my own device whenever I make another one.

Magic Eye Tubes! I've designed a project to show off the Russian 6E1P magic eye tubes.All the components are on one circuit board which needs to be powered by a regulated 12V power supply. There's a microphone on the board to make the tube respond to sounds in the room, plus a sensitivity control and optional external audio input on the back panel for connection to an audio system speaker etc.Here it is in action on YouTube...

Nixie Thermometer / HygrometerTubes, sensors and a micro in a single designNixie Thermometer / HygrometerMeasuring temperature and humidity with a modern sensor and displaying the values on a retro display — it’s all described in this article. A calibrated, ‘digital’ sensor provides data via its I2C interface to a microcontroller driving four Nixie tubes and automatically alternating between temperature and humidity, while providing a nice fading effect. It’s a must-have!Component listResistorsR1-R4 = 22kOhmR5,R11,R12 = 10kOhmR7 = 47kOhmR8 = not usedR9 = 820kOhmR10 = 330(R13 = 5.6kOhmR14 = 470kOhmR15 = 4.7kOhmR16 = 150(CapacitorsC1-C4 = 100pF 2000V, 10%, radial, 5mm pitch (Farnell #1141797)C5-C8,C11,C12,C16-C18 = 100nF 50V, 20%, pitch 5mmC9, C10 = 33pF 100V, 5%, 2.54mm pitchC13 = 10μF 250V, 20%, radial, 5mm pitchC14,C15 = 100μF 25V, 20%, radial, 2.5mm pitchC19 = 470pF, 100V, 10%, 5mm pitchInductorsL1 = 330μH 1A, 20%, axial, D×L = 11×32.5 mm (0.43”×1.28”) max.SemiconductorsD1 = BYV26D2-D4 = 1N4001IC1-IC4 = 74141 or K155ID1 (?155??1)IC5 = PIC16F876-20/SPIC6 = 7805IC7 = MC34063IC8 = SHT21 I2C humidity and temperature sensor [1] (Farnell #1855468)T1,T2 = MPSA42T3 = IRF820MiscellaneousX1 = 6MHz quartz crystalV1 = IN-19A, Nixie Tube (symbols)V2-V4 = IN-14, Nixie Tube (numeric)K1 = 2-way PCB terminal block, 5mm pitchPCB # 110321-1As you can see from the following pictures, the project progressed nicely…This picture shows the top view, without the last tube, which I was waiting forMost of the components are very easy to solder on. The Nixie tubes are very hard to get into the holes, but I managed it so anyone should be able to do it! However, the Sensirion SHT21 chip is 3mm x 3mm and is ridiculously hard to get on – this needs specialist attention and a steady hand. You can see the sensor in place in the picture below. Be sure to read the data sheet correctly, and don’t solder it on the wrong way (I *may* have done this!)The tubes eventually turned up – I was more excited than I probably should have been ??Finally the final tube came and was soldered into place – a really lovely display. The sensor has to be at least 15cms from the circuit board, otherwise you get spurious results from the heat of the components on the boardI built this case to house it, Im very very pleased with it
