The Internet Radio Demonstration Board uses the PIC18F67J60 8-bit microcontroller with integrated 10Base-T MAC and PHY to connect to SHOUTcast servers and stream MP3 data to an audio decoder. This demonstration board implements the basic features of an internet radio, such as volume control and station selection.

Found plastic flowers, foam, light sensors, mp3 players, microcontroller, speakers, birdsong
An ersatz version of nature; beautiful, yet a little bit deadly when one considers the natural resources required to create such impeccable imitations of vegetation. Is it also a reflection of human hubris... what else motivates the manufacturing of fake flowers? Why replace the ephemeral with plastic permanence? What joy is there in a whiff of a petroleum-based bouquet rather than the delicate scent of a rose? Secret Garden offers an opportunity to contemplate these questions at the same time it tries to seduce you with extravagant color and joyous birdsong performed just for you.

Building on the previous successes with the chipKIT WF32, the Wi-FIRE uses the same 43 available I/O pins, 12 analog inputs, 3.3 operating voltage, 4 user LEDs, potentiometer, buttons, uses MRF24 on-board wireless module, microSD Card, dedicated SPI Signals and high efficiency switching 3.3V switching power supply for low-power operation.
The Wi-FIRE is significantly faster than its WF32 counterpart, with 200 MHz operation speed, 2MB of Flash, 512kB RAM, High-Speed USB and a 50MHz SPI. The PIC32MZ core includes the MIPS M5150 CPU Core from Imagination Technologies. The M5150 is a highly efficient, compact core that is optimized for cloud-connected based projects, using Imagination Technologies' FlowCloud software.

The low-cost, low pin count PIC24F04KA201 family of 16-bit microcontrollers—the latest to feature nanoWatt XLP extreme low power technology—starts at less than $.99 each in high volumes. The PIC24F04KA family makes it even more cost effective to take advantage of the world’s lowest sleep-current consumption microcontrollers, with typical sleep currents as low as 20 nA. This low power and lower cost, combined with small-footprint 14- and 20-pin package options, makes the PIC24F04KA201 MCU family ideal for battery-powered applications, energy-harvesting applications and other power-constrained applications that are also cost and space constrained.

This is part of the schematic of my MIDI piano instructor. This thing drives a bar of LEDs placed on top of a piano keyboard (electronic or regular). MIDI messages play a MIDI melody through the electronic piano or a MIDI box and also drive the MIDI piano instructor which turns on and off the LEDs according to the notes played.

Parallax Inc. uses two milling machines in the production of hardware for products. These mills can cut different types of metals, such as steel and aluminum, which is frequently needed in the robotic kits engineered at Parallax. Many of the products we build on these machines may be more suitable for injection molding or metal stamping, but we really like the high-quality look, feel and finish of a milled and anodized aluminum part.

We ended up mounting the grease computer under the drivers side
dashboard. The frybrid grease computer has two significant roles.
1. It detects the temperature of the return coolant and allows us to
switch into veg mode when the coolant is near 180F.
2. It times the purge cycle and tells us when we can stop flushing
the fuel lines with diesel as to remove all the grease in the system
and prevent clogging.
Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced the MCP16301—Microchip’s first 30V-input, 600 milliampere (mA) buck switching regulator. The MCP16301 features a wide input voltage range from 4V to 30V, an output voltage range from 2V to 15V and provides up to 95 percent efficiency. The 600 mA MCP16301 is offered in a 6-pin SOT-23 package with an integrated high-side switch, and requires a minimal number of external components.

This is an laser cut enclosure for mobile arduino prototyping. I will start selling this soon. A bit more testing is needed.
Check:
The MRF24J40MB is Microchip’s second 2.4 GHz Radio Frequency (RF), surface-mountable transceiver module. This new module adds +20 decibels per milliwatt (dBm) of transmit power via an integrated Power Amplifier (PA) and -102 dBm of receive sensitivity via the integrated Low Noise Amplifier (LNA) to the proven IEEE 802.15.4 compliant transceiver, PCB antenna and discrete matching circuitry. More transmit power allows designers to expand the range of their IEEE 802.15.4-based ZigBee or proprietary-protocol wireless networks.

Your heart is like Microcontroller 8051,
But now you have become old,
I’ve got a more developed technology,
That is 8052 Microcontroller.
You have only two timers,
TM0 for your family and
TM1 for your carrier.
But 8052 has three timers,
TM0 for his family, TM1 for carrier
And TM2 for me.
You have only five interrupts,
So you have no time for me
When I call you,
But in 8052, there is no
Problem of time, because
He has six interrupts.

The amplifier will be located out of sight within the retrofitted cabinet record player, so a microcontroller receives, processes and forwards remote control signals. This is an IR led pointed at the amp's remote reciever.

Closer view of switches and indicator lights. HiViz users will recognize the little potentiometer wheels for adjusting the delay and sensitivity of the Multi-Trigger circuit. The two LED's from that circuit are mounted above them. I also added the switch on the right to replace the wire connecting the photogate with the delay unit for disabling the trigger outputs. At the left are power buttons to both microcontroller and trigger circuits and below that a power button to manually open the valve for purging the line, and start button to run the program for dropping one or two drops. The blue DIP switches are used to set the number of drops, delay between drops and drop size - see label and program listing for more details.

Auf diesem Foto kann man leider die Uhrzeit nicht so gut erkennen.
7-Segment-Anzeige Grove TM1637 mit Microcontroller NodeMCU LoLin V3 ESP8266. Es wird über WiFi eine Verbindung ins Internet aufbebaut und von einem NTP-Server die aktuelle Uhrzeit geholt. Danach zählt der Prozessor selbst weiter und zeigt die Uhrzeit an.
Nachdem es technisch funktioniert hat, habe ich selbst aus Klemmbausteinen ein würfel-förmiges Gehäuse gebaut.
The chipKIT™ WF32 is a prototyping platform that adds the performance of the Microchip® PIC32 microcontroller. The WF32 is the first board from Digilent to have a WiFi MRF24 and SD card on the board both with dedicated signals. The WF32 board takes advantage of the powerful PIC32MX695F512L microcontroller, which features a 32-bit MIPS processor core running at 80 MHz, 512K of flash program memory, and 128K of SRAM data memory. The WF32 can be programmed using the Multi-Platform Integrated Development Environment (MPIDE). It contains everything needed to start developing embedded applications. The WF32 features a USB serial port interface for connection to the MPIDE and can be powered via USB or by an external power supply. In addition, the WF32 is fully compatible with the advanced Microchip MPLAB® IDE and works with all MPLAB compatible in-system programmer/debuggers, such as the Microchip PICkit™3 or the Digilent chipKIT PGM.

There's a small torch bulb on that pair of long wires, with the glass removed. A single transistor (BFY51) sets up a constant current through the filament, and by blowing on it, I can vary the temperature and hence resistance of it. This shows up as voltage changes, which are sent to the Arduino's analog input to control a sine-wave generator.
All the soldering is done. Four 16-pin connectors bring out the ATmega32's ports, while a six-pin header is used for programming.
My CMUCam4 has arrived (latest Sparkfun)- it's a Camera which you can control in detail via serial connection. It's especially usefull in conjunctions with small Microcontrollers (like Atmel AVR, ti MSP430, ti C2000, small Motorolla microcontollers, etc). You can train it to track collors or motion and you can use it's output in programms you can write for Arduino Boards for example. This is one of my first (completly underexposed :)) tracking targets (a sheet of paper illuminated by my bicycle lamp)
Power-over-Ethernet magnetometer. The microcontroller will be added after initial construction tests have been performed. This newer version incorporates some very minor revisions compared to the original design (retaining wire for 32768Hz crystal, minor track routing changes, decoupling added for voltage measurement and fan).
