They are Alive…!

The *uino-1284p assembled

Over the past few days I assembled one each of the *uino-1284p and *uino-32u4. Things went very well and few issues were encountered.

The *uino-32u4 went together flawless. For initial testing I used the Arduino Leonardo bootloader and core files. Since my pinout differs from the Arduino Leonardo this required some translating

Yet Another *uino-1284p

The *uino-1284p v0.2 PCB Top

Today I received more *uino-1284p boards. The other day I already received *uino-1284p boards. Those boards were version 0.3 boards. The boards received today are the predecessor, version 0.2. I have been discussing my ATmega1284p ideas on the Arduino Forum. I had thought that what I accomplished with this

The *uino-1284p Has Arrived

The *uino-1284p v0.3 PCB Top

Here it is! The *uino-1284p has arrived. It is an Arduino compatible platform based on the ATmega1284P-AU. The *uino-1284p board utilizes the ATmega1284P microcontroller. The primary goal of this project is to be able to access more memory, FLASH and RAM, while keeping the Arduino UNO compatible board size

The *uino-32u4 Has Arrived

The *uino-32u4 Circuit Board Order

I have already written about the ATmega32U4 based *uino-32u4 I’ve created. Today I received the circuit board order. The order was placed with Seeed Studio’s Fusion PCB Service on December 24, 2011 and arrived at my door on January 13, 2012. I am impressed, at the speedy service and

Arduino Duemilanove

For some reason I had an ATmega168 and an ATmega328 sitting in my parts bins. To put them to use a couple bare PCB were ordered from a Chinese vendor on eBay. The boards I received were in superb condition. Most surface mount components were 0805 size, except for the FDTI chip of course.

The *uino-32u4 Is Born

*uino-32u4

I have been thinking about some electronics projects again. While looking at processors and other details I discovered Arduino and also the Arduino compatible chipKit UNO32. These are some pretty neat devices which come with a development platform that runs on Windows, Linux and Mac OS X.

Instead of buying an original Arduino

AVR Dragon

The Atmel AVR Dragon is a new programmer for Atmel AVR 8-bit Microcontrollers. I obtained this little beast because my old AVRISP serial programmer was useless due to lack of serial hardware on my PC. The Dragon was quite inexpensive and readily available at DigiKey. It promised to not only provide ISP (In-circuit Serial Programming),

Servo Tester

I needed a device to test R/C servos. Hooking up receiver, battery, servos and then running the transmitter with the antenna extended inside the house was awkward. I thought this could be a nice little project for some microcontroller. After a long abstinence from PIC assembler, I downloaded the latest MPLAB release and programmed away.

Microchip PIC Analog Clock

During the summer of 1998 I built yet another PIC based clock. I had an old LED analog clock kicking around. It was a CMOS logic design built from an ELV (a German electronics magazine) kit. The clock lost its time every single time there was the slightest brownout, it bothered me to no end.

Microchip PIC Room Thermostat

During spring and summer of 1998 I developed my second project utilizing a Microchip PIC processor. The primary purpose was to explore character LCD displays and 2-wire bus (I2C) devices with a Microchip PIC microcontroller. The project was a digital room thermostat with multiple setpoints at different times of the day.
