thanks for sharing this projet, however is it possible directly connect the camera directly with Sim7100 and have video streaming while control the Sim7100 module with host MCU?

hiis there any schematic or eagle file for any development board of 7100E series ?

great project, however have you try to do animation show using ESP8266 UDP protocol as bridge betwwen video server and LED pannel ?

thanks @eric for detail explanation , actually I'm looking for some general design to control different DC motors in my Arduino project ,I'v find many designs in internet which used the mosfet gate driver instead of combination of transistors , also following link explained how is important to isolate gates and protections circuits in high power mosfet , I really appreciated to have your comments about these new IC's and design in high power DC motor controlhttp://www.analog.com/en/analog-dialogue/articles/...

Thanks @swansong , but I don't know how to enter "First Time Authors contest"

excellent piece of art buddy , specially the moving tracks , how strong they are ? do you have idea about how to make the robust and reliable metal or non metal tracks ?is it possible, to mount DC motor and Arduino shield to move these device ?Thanks

nice job without Fet module , however I was wondering if you've had any research for using the high power IGBT module and its pre driver to control large BLDC motor using in electric car, any advise really appreciated

thanks for sharing your experience however I was wonder if you know healthy way without frying oil, because I'm not fan of using oil for cooking , BR

thanks for sharing such neat project , However I interested to simplest solution like use raspberry pi as client which can connect to server by Ethernet or USB and play video stream , may I have your advise for such project

I set feed rate to 10000 mm/s and acc to 500, but not big changes , I suspicious the CAM software and then new GRBL1.1f, I setup my CNC laser with Marline firmware which is used inkspace raster extension , the engraving was so fast

hi , thanks for sharing this neat project, however I've been trying to use GRBL 1.1f version (which has laser mode feature) to engrave with my 100 watt CNC laser , but the engraving speed so slow and increase the feed rate is not affected so much , may I have your advise how to reach to maximum possible speed ?BR

thanks for sharing your project , actually I use the new grbl 1.1f but when I feed my gcode file to machine , it shows slow performance whereas I saw many engraving use fast movements, I've tried to use higher feedrate but its not very useful and its changed a bit , do you have any idea where should I seek this issue ? on CAM side or machine side ?BR

very neat project , I was wonder if there is any solution in market so we could convert our old laptop to the tablet , I mean using such raspberry board just the prototype hobby solution , but special ready- to- use board to convert old devices could be huge save

very nice art , have you know any links to gallery for such beautiful art made things

nice job , buddy , can you share eagle files ?BR

thanks for sharing your experience , however I've tried to power up my external HDD with external 5.4 vcc power but the my built usb adapter not recognized by windows whereas my mouse work well with that , do you have any advise or hint ?is it possible somehow noise affected usb connection?following is the image of my adapter which is easily made by simple male /female usb connector

good job @lingib but I was wondering why do you choose the hard way and compose the CAM code by yourself , why just don't use the open source rich community CNC interrupter like GBRL and Marlin?

thanks for information , but what if we intend to present the received sub data in the webserver (XAMP) installed on raspberry pi as well, I mean maybe there is instruction to put received data in mysql . then server use stored data as per its clients request ?any help really appreciated

thanks for sharing your experience, do you have any experience or know links to control the VFD invertors by Arduino module

hi , thanks for sharing such elegant board and design , as that mosfet designed for switch purpose , it is possible to use mosfet for reading the low current device (week signal)? actually I've tried to read My PIR sensor status by transistor but it is too week to drive the transistor , I thought maybe by mosfet can read such week signal , any hint really appreciated

hi , thanks for sharing the great job , however I was wondering that if have any plan to rewrite the project in Arduino IDE instead of Lua environment ,

thanks for tips , mine now work with 15 & 13 NodeMCU pin ,

very nice project and thanks for sharing , however I appreciated if you be more specific or direct me to how make the LED table be interactive , I ran the same project with ws2812 LED strip beneath the 7cm translucent plexiglass , but not yet figure out how to make my table interactive. as you said there is couple of sensor to use for but maybe in practical not easy as it look

thanks for sharing such experience , actually I've tried to perform such task but I don't know why the software serial can't communicate with GSM module whereas can easily communicate with other modules serial interface, I've checked with different voltage divider and GPIOs , but no success , I really appreciated for any hint
