Fit ESP-12 Breakout Board on breadboard

I have a ESP8266 ESP-12 WiFi Module (Full I/O) Breakout Board. But the board cover whole the width of breadboard, such that cannot insert breadboard wire. Alternatively, I have some pre-cut wires for breadboard, can be inserted under the breakout board to make it fit on breadboard.

I also add a breadboard power supply (3.3V selectable), a FTDI adapter and button for flashing firmware. And wires to lead out the GPIO16, 14, 12 and 13 for future use.

Here is the wires placement:

Low cost ESP-12 (ESP8266 WiFi module)

It's ESP-12 (ESP8266 WiFi module) on breakout board, with all I/O pin accessible. Bought from China TaoBao (淘寶) market, cost RMB ¥15.00/pc :)

(have to solder the ESP-12 on breakout board by myself)

Test with example of "Arduino Due + ESP8266 - to Join AP".

Assemble, test, align and power-up DSO138, Open-sourced Oscilloscope DIY kit

Just purchased a Open-source Oscilloscope DIY kit DSO138, with surface mount components soldered. Here how I assembled it in 2 hours.


After assembled, check voltage on TP22. Make sure it is arround 3.3V. Then short JP4 and install LCD module.


Notice: This video recorded after my final tested, so JP4 have been shorted at beginning. Actually, you have to keep it open after 3.3V on TP22 confirmed.

After the kit worked, align the 0V line and calibrate the probe.





For details and update of the DSO 138 DIY Kit, read Users Manual on the website.

Tested with Arduino Due generated sin wave.

Open-sourced DSO (Digital Storage Oscilloscope) DIY kit - DSO138

Interesting open-sourced digital oscilloscope DIY kit, DSO138, think about buying one. But I can't find the source in the web-site, and instruction to flash the firmware!

http://www.jyetech.com/Products/LcdScope/e138.php

DSO138 was designed as a training oscilloscope kit. It contains only the basical oscilloscope functions with no fancy features. Simplicity in structure and easiness in assembly/operation are among the main targets of the design. For these purpose DSO138 uses mostly through-hole parts. The heart of DSO138 is a Cortex-M3 ARM processor (STM32F103C8) from ST. It uses 2.4-inch TFT LCD (320 X 240 dotmatrix, 262K colors) as its display element and displays nice and clear waveforms. Detailed assembly instructions are provided in combination with troubleshooting guide and schematc. Source codes are also available to allow user to add their own features.

DSO138 kits are solded in two configurations. One is with all SMD parts pre-soldered (PN: 13801K). The other is with only the main IC (the MCU) pre-soldered (PN: 13802K). The latter serves also as a SMD soldering training kit. For both configurations the MCU has been pre-programmed and no re-programming required.

DSO138 is partially open-sourced. This opens the possibility for users to add different features or develop new applications on the hardware.

Major features of DSO138: 

• Analog bandwidth: 0 - 200KHz
• Sampling rate: 1Msps max
• Sensitivity: 10mV/Div - 5V/Div
• Sensitivity error: < 5%
• Vertical resolution: 12-bit
• Timebase: 10us/Div - 500s/Div
• Record length: 1024 points
• Built-in 1KHz/3.3V test signal
• Waveform frozen (HOLD) function available

Finally I bought my own DSO138 kit, read Assemble, test, align and power-up DSO138, Open-sourced Oscilloscope DIY kit.

Arduino BASIC - a BASIC interpreter running on an Arduino

Now you can turn your Arduino into an 80's home computer!

A complete BASIC interpreter for the Arduino, using a PS/2 keyboard, and SPI OLED screen. The BASIC supports almost all the usual features, with float and string variables, multi-dimensional arrays, FOR-NEXT, GOSUB-RETURN, etc. Saving and Loading from EEPROM is supported, as well as auto-running a program on power-up. You can also read and write from the analog and digital pins.

There's about 1k of RAM available for your BASIC programs and variables, so its roughly equivalent to my first computer (a Sinclair ZX81). The other 1k of RAM (on an UNO) is used for the keyboard and screen buffers, with a small bit of room left for the CPU stack. That works out quite well, since there's a 1k EEPROM on the arduino so if your program fits in the basic environment, it will fit when saved to EEPROM!

Getting Started with BeagleBone: Linux-Powered Electronic Projects With Python and JavaScript

Many people think of Linux as a computer operating system, running on users' desktops and powering servers. But Linux can also be found inside many consumer electronics devices. Whether they're the brains of a cell phone, cable box, or exercise bike, embedded Linux systems blur the distinction between computer and device.

Many makers love microcontroller platforms such as Arduino, but as the complexity increases in their projects, they need more power for applications, such as computer vision. The BeagleBone is an embedded Linux board for makers. It's got built-in networking, many inputs and outputs, and a fast processor to handle demanding tasks. This book introduces you to both the original BeagleBone and the new BeagleBone Black and gets you started with projects that take advantage of the board's processing power and its ability to interface with the outside world.
