Arduino Nano connection error (CH340/CH340G driver)

Recently, I’ve got some cheap Arduino Nano from Internet for about 5 USD. However, I was struggle with the connection issues that my Arduino program cannot regonize my Nano chips.
The error message is kind of like this

And I found out that the new Arduino nano has a different USB connection chip which is CH340G compared to the previous FTDI one.

The new nano(left) and the old one I bought have some different chip layout.

After installing the driver from the manufacture from China, the problem finally sloved.

You can download the driver from here if you have encounter the same problem.
WCH CH340G driver
Just click on the download button.

For Mac and Linux I think this two file might work!

Arduino CNC shield control Stepper motor with DRV8825

CNC shield is quite useful for stepper motor driving. Here, I demonstrated how to use simple arduino code to drive stepper motor with DRV8825. First, just simply mount CNC shield onto Arduino Uno. Make sure the direction of the shield was right, where both the USB port and power supply wire was on your left hand site. The blue wire is my power supply which can be connect to 12-36V of power source. Next step you can mount the DRV8825 chip onto the CNC shield. Make sure the DRV8825 chip goes like this direction. If you put the chip in the wrong direction, you will probably damage it. By adjusting the jumber underneath the DRV8825 chip, motors can be driven with different kind of microstepping mode. I put three number here so it means that I set it into 1/32 step driving mode. Which is the most precise one of DRV8825. The motor can connect to the right site of the DRV8825. Plug in the usb to your computer and upload these coded which will generate...

Setting up CUDA 10.0 for mxnet on Google Colaboratory

Preface Recently, I was trying to train model on Google Colaboratory with mxnet. However, I found the CUDA version pre-installed on the Colab. is 10.2. Till now, mxnet only support to CUDA 10.1 Therefore, I started to think about if it is possible to setup the environment that mxnet has support. Till now CUDA 10.1 doesn’t work for me. But I do successfully installed CUDA 10.0. Also tried to trained a LeNet on Colaboratory. Since I am a mac user, NVIDIA GPU is always what we are jealous and envy. Until I found Google Colaboratory…. I’d like to share my journey with you, if you also encounter some problem on setting up environment. Google Colaboratory provide free access to the NVIDIA Tesla K80 GPU (24GB RAM, 4992 CUDA core) . It is a great gift for most of people who is eager to learn deep learning but doesn’t have good hardware systems to train deeper models. NVIDIA Tesla K80 GPU I assume that you already have background knowledge of Python and familiar with tools like jup...
