This is to connect a microcontroller and an audio device via BT. Credits are going Frank Zhao for his design of BT headphones.
Microchip announced the availability of its MPLAB® Code Configurator. This new code development tool accelerates application development using 8-bit PIC® microcontrollers (MCUs). Additionally, this tool enables developers to enhance the design experience with custom application development. The MPLAB Code Configurator is a user friendly plug-in tool for the MPLAB® X Integrated Development Environment (IDE) that generates drivers for controlling and driving the peripherals inside PIC microcontrollers, based on the settings and selections made in its user interface. A key feature of this tool is that it produces the peripheral starter code, which is easy to migrate between similar peripherals and products. The generated driver functions can be used in many different application programs, providing a very powerful and extremely easy-to-use development platform.

Atmel AVR Butterfly microcontroller evaluation kit. Also has temperature sensor and speaker. The best thing - it's only $20!
I picked mine up from Smiley Micros because they threw in a serial header and wires for free.
I have recently purchased an Arduino microcontroller board. It will run software to control activation of lamps, polling of sensors and the dot matrix display.
At the bottom right you can see my new protoboard which I am usnig to test the lamp controlling circuits. I have already had some partial success. I am really an electronics newbie...
An old chip that i opened to see what's inside.
It's an Intel 8742, a 8-bit microcontroller that includes a CPU running at 12 MHz, 128 bytes of RAM, 2048 byte of EPROM, and I/O in the same chip.
See the official doc (pdf) on the intel's website, or see a shot of the whole thing.
Thank you to kingey1971 for the identification !

This is the master board for the display. It holds the microcontroller, the USB controller, and the two power supplies (3.6V for the display, and 5V for USB). The micro is responsible for powering everything up, instructing the USB controller to find the video file and start retrieving its contents, and to stream that video data out to the display boards. The displays can all be daisy-chained together, but I have them split between two identical headers just to reduce the current (and voltage drop) in the chain.
Breadboard circuit for Sound Flash Trigger With Delay (Mk I)
My long absence from Flickr has been due to me devoting a lot of my spare time to re-learning electronics and learning how to develop software for microcontrollers.
This prototype circuit was my first attempt to build a sound trigger for my Canon Speedlites -- as I had modified my OC-E2 flash extension cable I was able connect directly to any of my Speedlites.
Unfortunately, I discovered that the timing ICs I was hoping to use (NE555) are just too slow to respond to the sound of a balloon popping. The shortest delay I could get out of them was roughly 2ms which just wasn't fast enough.
So my next move was to use microcontrollers, initial the PIC 16F628A, but I migrated to the AVR ATmega8. The AVR has an open source GCC development environment and the AVR are available here in Portland (Surplus Gizmos on Cornelius Pass just off of Hwy 26).
The circuit has five stages:
1) The audio amplifier using a LM386 OpAmp IC
2) A comparator to convert the amplified audio into a distinct pulse to trigger the timer delay circuit
3) The first timer (NE555 IC) which is the delay part
4) The second timer (NE555 IC) which generates the trigger pulse for the Speedlite
5) The opto-isolator (MOC3020 IC) which triggers the Speedlite, but protects both this circuit and the Speedlite. With this setup I could use an older hot-shoe flash which are notorious for running 300V between the hot-shoe pins.
Like I said, unfortunately this prototype was just too slow, but I learned a lot in the process.
Side-note: Canon Speedlites can't be triggered repeatedly with just an opto-isolater by itself. Due to some quirk in their design you have to add resistor and capacitor in parallel (to each other) to help reset the Speedlite after it is triggered. I used a 1M ohm resistor with a 0.05uF capacitor rated for 600V.
It's a Microcontroller Based DIY Electronics Project. Named Wireless RF Module Using PIC Microcontroller. The RF module is a small electronic circuit used to transmit, receive, or transceive radio waves on one of a number of carrier frequencies. RF modules are widely used in consumer applications such as garage door openers, wireless alarm systems, industrial remote controls, smart sensor applications, weather monitoring system, RFID, wireless mouse technology and wireless home automation systems. They are often used instead of infrared remote controls as they have the advantage of not requiring line-of-sight operation. Stay tuned for Furthur Links, Thanxx.
This is a fully Arduino-compatible setup based on the Arduino breadboard except with a USB to serial converter and an RS232 level shifter instead of the FTDI chip. I used the parallel cable I'd made previously to burn the bootloader, then I was able to program it and to communicate with it via USB. This was all done using the normal Arduino software on Linux.

A prototype reflow oven controller. A Teensy++ 2.0 provides an 8-bit AVR microcontroller to run the control algorithm. Two MAX6675 ICs provide two channels of thermocouple sensor readings. Two solid-state relays allow independent control of two high-power AC loads (the top and bottom heating elements of my toaster oven, in this case).
The whole PID control algorithm and temperature profile reside in and execute on the AVR (all implemented with fixed-point integer math). Still, I've also written a Python/QT GUI program that talks to the AVR (through a USB virtual serial port) and allows for plotting the reflow profile/sensor readings/SSR commands/etc. in real-time as the reflow operation runs.

These are rather difficult to assemble by hand - I'm not entirely sure I have the tiny CSP regulator on in the right orientation :)
Beyond that, I managed to put one of the LEDs on backwards too (far right), and one of the regulators might be unconnected (far left)
More progress on these eventually... Need to work on other things for a bit first.
This project is designed to develop as a robotic vehicle that can be controlled by a cell phones. DTMF commands from a phone send to another cell phone which is mounted on the robotic vehicle. These commands are fed to a PIC microcontroller of 8-bit architecture to operate the vehicle movement through motor interface.
Conventionally Wireless-controlled Robots Use Rf Circuits, Which Have Limited Working Range, Limited Frequency Range and Limited Control. Use of a Mobile Phone for Robotic Control Can Overcome These Limitations. It Provides the Advantage of Robust Control, Working Range as Large as the Area of the Service Provider, No Interference with Other Controllers. Although the Appearance and Capabilities of Robot Vary Vastly, All Robots Share Feature of a Mechanical, Movable Structure Under Some Form of Control. The Control of Robot Involves Three Distinct Phases: Perception, Processing and Action. Generally, the Preceptors Are Sensors Mounted on the Robot, Processing is Done by the On-board Microcontroller or Processor, and the Task is Performed Using Motors or with Some Other Actuators. In This Project the Robot is Connected to Gsm mobile (using DTMF technology) Which is Controlled by User Mobile Phone. With the Help of Commands We Can Move Our Robot in Desired Direction as Per Our Requirement.

Microchip reclaimed the number-one position in worldwide 8-bit microcontroller (MCU) revenue, according to industry analyst firm Gartner’s 2014 rankings. This validates Microchip’s unwavering commitment and innovation efforts for its 8-bit PIC® microcontroller portfolio. While many MCU vendors have deemphasized their 8-bit offerings in recent years, Microchip has continued to innovate across all of its 8-bit, 16-bit and 32-bit product lines. And it continues to grow market share in all three areas, according to Gartner’s 2014 report. In the 16-bit MCU market, Microchip was the fastest-growing supplier among the top 10 in 2014, growing at greater than 2X the rate of any of the other top 10 companies. Its 32-bit MCUs broke into the top 10 ranking of 32-bit MCU suppliers for the first time in 2014, based on 42.3% growth. For more info, visit www.microchip.com/Homepage-042715a.
