Titanium mining Download

1. Wait, you call this thing titanium drill? Do you know the color of titanium diamond is platinum?

2. Simple Python tutorial.. Thank you.
after reading it, just look at the operation of GPIO again. It seems that there is nothing complicated

4. Why should I pay it back if I borrow it according to my ability

5. What editor do you use to edit text? Generally, the VIM editor will be used to edit the text. At this time, you can directly use the shortcut keys Ctrl + C and Ctrl + V to and paste the text, or you can use the mouse to select the text, and then use the right mouse button to and paste it
if you are interested in Linux system and want to learn more Linux system commands, you can learn "this is how to learn Linux" on the Internet, which is a good introction to Linux.

6. First install the system (I installed Linux), and then look for tutorials on the Internet, such as Python and C + + (the content is similar to the development software, but you can control some electronic small parts through programming). After learning more, you can also make many interesting inventions!

7. You are a junior. I haven't used this hardware, so I can't write ready-made code for you. I suggest you do it yourself. One summer vacation is enough time to do it. If you don't discuss it with the students around you first. There will be a harvest

8. Raspberry pie + SD card + mobile phone power: Raspberry pie bought online; SD card was removed from the camera; The power supply is the same as the original mobile phone, and the interface is universal
5V relay: control the three wire (power, ground and signal)
tendaw311mi small wireless routing
several wiring methods / steps
raspberry pie wiring diagram: SD card, mobile phone power line, network cable, HDMI to DVI wiring to connect the display Keyboard
how to use raspberry pi to make a simple control system
install raspberry Pi's Linux system: the system goes to the official website, and writes it into SD card with tools (quite simple online, many tutorials)
raspberry PI can access the Internet through cable: at the beginning, there was no monitor, I bought a HDMI to DVI interface cable, and after debugging, I didn't need to connect the monitor, In the home, you can connect the router by cable and connect the LAN IP with SecureCRT, then you can log in to raspberry pie, Ping the Internet, and basically get through the raspberry pie wireless network card: insert the wireless network card into the USB interface, tendaw311mi can identify without driver, modify the / etc / network / interfaces information, add the WPA SSID and WPA PSK of the router, and restart the system, Basically, you can access the Internet wirelessly
relay: the so-called relay is a kind of control switch, which uses small voltage and small current equipment to control large voltage and large current. The power supply, GND ground and signal of the control terminal are connected to the 2, 6 and 7 interfaces of the GPIO of raspberry pie respectively (the control terminal should have three wires, originally bought a two-wire input, I heard that it could be used, but I didn't dare to connect it in the end...), Programming: download the GPIO library with Python installed, and then give the following control code:
file run. Py
#/ usr/bin/python
#coding: utf8
import sys
import RPi.GPIO as GPIO
PORT=7
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BOARD)
GPIO.setup(PORT,GPIO.OUT)
if sys.argv[1]==" open":< br /> GPIO.setup(PORT,GPIO.LOW)
elif sys.argv[1]==" close":
GPIO. Setup (port, GPIO. High)
OK, after the top is finished, pick up whatever you want, and then SecureCRT logs in to raspberry pie,
sudo. / run.py open / / turn on the control device
sudo. / run.py close / / turn off the control device

use web.py to build a simple web server on raspberry pie, change the above run.py script, and you can access the control switch through your mobile phone, Realize the remote control in the home.

9. I often come here to dispense medicine. The inside environment is pretty good, but the attitude of the small doctors is very good, and they are also very polite to the elderly. The nurses' technique is also good, and they feel that the money they pay is cheaper than the big hospitals
