Atmel EEPROM Cufflinks!

At first look, the Atmel chip reminds me of Atmel microocntroller series but it turns out it’s actually an EEPROM.  Neverthless, this is a cool Cufflink I don’t want to wear around.

Here’s a cool DIY on how to make an LED Cube!

64 LEDs makes up this 4 by 4 by 4 cube, controlled by an Atmel Atmega16 microcontroller.
Each LED can be addressed individually in software, enabling it to display amazing 3d animations!

Yes, this is something that we need the most…a Printball Paintball Printer!

Lol… I wonder if you can “miss”…

The PrintBall is like an Ink-Jet printer using a PaintBall Gun as printhead. The gun is mounted on a custum made pan & tilt unit which is connected to a Max/Msp based software through an Atmel chip [programmed in Basic]. The software allow the users to load and analyze images. The resolution of the image and the space between the point [definition the image] can be ajusted.
Because the document is printed from a central point the number of steps by points send to the pan & tilt, which is moved by two stepper motors, one for each axe horizontal and vertical, determine the space between each point.

Check out the Atmel AVR temperature controller hack, although I made a better one last year that can be controlled via ethernet, the case looks awesome!

Wine doesn’t like subzero temperatures, and during wintertime, my “winecellar” got pretty cold.
There was an electric heating element, but the thermostat was broken, so it was either full burn or nothing.

That’s how the temperature monitor/controller came to be.
It was an obvious task for a small processor and I’ve always wanted to test the Dallas temperature sensors.

So, I designed this little device which could monitor the temperature and control the heater.

Into AVR chip programming? Check out how you can convert an Arduino into an AVR chip programming hardware for use with AVRDude!

By the way, AVR is microcontrollers from Atmel. Check out AVRFreaks for good AVR info.

(Thanks David for the tip! )

I ported the Atmel AVR910 In System Programmer protocol to the Arduino. Now I can write programs to my ATtiny2313 and tiny13 chips. The Arduino sketch is available for download here. It works with the AVRDude programming software. This article will show how to use the Arduino to upload a program to the tiny13. The first step is to download the zip, extract the .pde file, then load it into the Arduino IDE, and write it to the Arduino. Next we can hook up the tiny13 chip.

The original AVR910 programmer didn’t support the tiny13 chip. I added tiny13 support to the Arduino version and assigned it part ID 1. I had to modify the avrdude.conf file also. I just added the following line

This is sick! Check out the servo snakebot using an Atmel Atmega32 microcontroller and bunch of Futaba servos!  You can see more videos of the snakebot here.

The robot consists of nine cars connected with eight Futaba servos controlled by a microcontroller. All wheels are passive, the locomotion comes entirely from lateral undulation, which is wave movements in the plane similar to a snake.

Check out voltmeter and ammeter LCD panel you can make using an Atmel8 MCU. Tight!

This multimeter was designed to measure output voltage and current in a PSU, where the current sense shunt resistor is connected in series with load at the negative voltage rail. It needs only one supply voltage that can be acquired from main PSU. An additional function of the multimeter is that it can control (switch on and off) an electric fan used to cool the main heatsink. The power threshold at which the fan switches on can be adjusted using One Touch Button Setup.

Check out this great prototyping technique! Thanks dwrenne!

To build any electronics handicrafts, there are some wiring materials. I think most people are wiring circuit board with PTFE (Teflon) insurated wire. But the PTFE wire is not suitable for wiring material with solder due to following reasons.

• Wires on the circuit board gets like a dish of pasta when wired many number of wires because its insulator is tick.
• And changing a part of the circuit will be difficult.
• Working efficiency is not good, each wire must be stripped to be solderd.

So I recommend to use UEW for protoboard. The UEW is polyurethane coated copper wire which is used to inductors and small transformers. This wiring method is minor way, yet. However, it has cleard that problems, so that it is better way for wiring on the protoboard.
To wire with UEW, a wiring tool called “wiring pen” is used. The wiring pen is often sold with PCB kits, however, they are not useful because its tip is dull. When you did not satisfy bought wiring pen, it will be better to build it yourself. I built the wiring pen from a drawing pen.

Here’s a cool DIY oscilloscope using a PIC12F675 kinda similar to the Atmega Atmel Oscilloscope.

This is a simple PC voltage oscilloscope using only a PIC12F675, a 20MHz oscillator, and a RS232 level shifter. The PIC takes a sample on GP2, immediately sends it to the PC at 115,200 baud using an software asynchronous serial routine, and repeats. It sends a 8-bit value that is read by the Visual Basic software and displayed on the screen (see examples below). The Visual Basic software deduces the time period between submissions and adjusts the display accordingly.
