Yes, sure. Any chip have I2C feature can do the job.

Hi Fabio, in this instructables, all code and HTML stored at ESP8266. Thats mean you do not require an extract client e.g. AppInventor2. Simple use your mobile share WiFi to the Robot and then browse to the Robot webpage to control it. The only things you need to revise is the HTML and some simple GPIO response on the WebSocket message.

Hi, MansourFatna. tiawild have reported a few problems, which one you encountered? Can you flash the firmware at step 4 properly? And I think this old instructables is a little bit outdated. Since Arduino ESP8266 already officially support 16 MB flash, I think you should try Arduino IDE first.

The esp32-nesemu have many branches variation, I see some can store 6 ROMs to the internal flash and some can load ROMs from microSD card, i.e. not limit the number of games.

402050 should be well fitted into the 3D printed case

The most important thing is read the datasheet before buying it.

Hi SandraN30, there 2 GND pins and 4 LED- pins in LCD FPC require connect to GND. I am lazy to connect it one by one, so I cut a copper tape that can just reach these 6 pins, then soldering it together.

Yes, I think. Arduino ESP8266 support already added 8 MB and 16 MB option.

I think IoT in most case require some sort of server. Imagine you have ten of them in an area, it is time consuming to access the data one by one.

I am very sorry to hear that you do not want that editor, I will to design it for better UX next time.

If you really want to use Arduino only, try my new instructables: https://www.instructables.com/id/IoT-Emoji-Sign/

Any Lipo with size 5 mm x 23 mm x 45 mm is ok, I think the one in the photo is a 502035.

try google "usb charging flashlight board"

try google "usb charging flashlight board"

The image file name said it is scaled 4x, so you should resize to 25% first. Then adjust variables in HTML, wild guess it should be xo = 2, yo = 2, xs = 9, ys = 9

This is my new NeoPixel project written in Arduino IDE: https://www.instructables.com/id/IoT-Emoji-Sign/

Yes, simply add the picture to the color map.

Same as Raspberry Pi, it comes from UK, but less popular in adult hobby world.

Seems you have extracted ESP8266WiFiAnalyzer-master to libraries folder. You don’t need to do this, try remove it first.

Hi СергейЩ, simple google the model number JLX240-00302-BN can find taobao 1688 are selling it.

Yes, just real time download a picture and show it every minute. It should also work with ESP8266, but be aware JPG decode require certain RAM to do the job,

You can reconfigure the input in emulation station setting menu.

If you cannot print it yourself, you may order a print out on the web.

Check out https://github.com/moononournation/ATtinyWatch/blo...Modify ssd1306.h, define correct screen size.

you may try to google “easy chip charging board”

If you can find the charge board in the photo, any 5V Lipo charge board should be ok.

The main cost is RPi0 and Waveshare 1.3” LCD HAT

"x" only means a wild card. If you have some resistors between around 10 - 300 Ohm, you can try one by one which brightness can fit you.

Hi stoppi71, I am using the connection setup mentioned at step 17.

Hi xile6, the output of BanateCAD is ASCII STL. You can convert it to Binary STL by another software e.g. meshlab or 3D Builder. It is much smaller.

The high resolution map files not owned by me, you may buy it at the link in instructables.

As mentioned in the instructables, the STL is generated by BanateCAD. I have no other format (IGES/STEP) for this model. You may Google how to convert it from STL file.

Hi DavidC1311, I have push the RPi run SPI to run at max speed by "speed=125000000". The SPI speed is very depends on the chip support and wiring quality. you may try to lower the speed to 40000000.

you should run the batch file directly

I bought it at Taobao.

If you cannot find that board, you may try to add a ~1x ~ 2xx Ohm resistor in series.

Ok, I know the problem now, the path is incorrect. I have committed the fix, please get the latest BanateCAD.

Hi JimmyH91, what version of Lua are you using?

Succeeded?

Hi thetaylors979, yes it require cmake to compile fbcp. Latest RetroPie image (4.4) already installed it. If you are using another image, you may require install it manually.

Simply run the script.

Hi Thorondor95, I am using latest RetroPie image and I think it can emulate most NES game well. As mentioned in article, the number of buttons limited it cannot emulate the console with more then 4 buttons, e.g. SNES. And also no sound yet but the circuit is ready, it just because no room for it. About the FPS, using fbcp can have 1x fps, not as smooth as 30 or 60 fps but already good enough for NES game.

If you tried this tiny board, you will know why it need a ball shape to control it well. FYI, the ball is only 7 mm in diameter and only around 3 mm taller then the original stick.

Here is winter now and not so hot after turned on over an hour. May need further test in Summer time.

Good! wait for it!

The charge board direct connected to RPi 5 V pin, simply plug the RPi is charging the battery.

Yes it can, it just no room to add extra parts. If it has a new version of LCD HAT builtin this feature is great!

Good, you may also want to print the Progressive Detail Moon Lamp next.

CS stands for cable select, it tell the device the SPI is active for that device. If you only have 1 device connected to the the SPI, you can simply pull down the CS pin to tell it always active. It can also simplify the code no need turn CS on and off for each message and run a little bit faster. Some breakout board not wire out CS pin and simply pull it down for you.

0.2 mm for 5 inches; 0.1 mm for below 5 inches.

thx

may be you can find some in old mobile phone.

Hi davidd7, the answer is yes you can. As mentioned in my previous instrctables, once you know the method, you can use your familiar software to do the same thing. I choose BanateCAD just because my machine not capable handle this high resolution with GUI software.

Please refer to Step 19: Ornament Lighting

Thx TinkerJim, I have updated the origin.

dev dock only a simple circuit connect DTR and RTS to GPIO 0 and reset pins. If you insist don’t like connect this circuit, simply pull down GPIO 0 manually and then reset ESP32 to enter program model before you press upload in Arduino IDE.

I never tried connect SD card myself, but I have tried M5Stack, ESP32 should work with SD well.

Hi mohandhanush25, did you encounter any problems while following my steps?

for power saving, you may find more info in my previous instructables: https://www.instructables.com/id/Battery-Powered-ESP-Design/

Sticky follow step 11 details.

Hi StephenB6, dtoverlay=dwc2 only apply to the Pi version without USB hub, i.e. Pi Zero and Pi A(+). ".." is only a convention notation of the original text.

Hi ScottB414, sorry for misleading. 135 is the sample angle if you want to print a ceiling lamp.

This is a 9 years old project, I have already sold out all my 10 thousands stock. You may give me an address at private message box to buy one while stock last ;)
