20140518091311-AnyTracerGPS

Track and Trace anything with the Arduino AnyTracer of only 25 x 25 mm! It is the smallest, complete GPS GSM tracker in the entire world.

A movie is not necessary here! The photos speak for itself. Together with the best Italian and Russian GPS specialists we managed to make the smallest complete GPS GSM tracker in the world. This tracker is only 25 x 25 mm! With the onboard STM32 microcontroller you can program it yourself with Arduino or online (!) with Mbed.org or in C using Keil or the opensource CooCox IDE. Almost anybody can do the programming with their own beloved platform.

This Reflow Oven Controller relies on an Arduino Pro Micro, which is similar to the Leonardo and easily obtainable on eb*y for less than $10, plus my custom shield, which is actually more like a motherboard.

As I believe it is not wise to have a mess of wiring and tiny breakout-boards for operating mains powered equipment, I’ve decided to design custom board with easily obtainable components.

The hardware can be found in the folder hardware, including the Eagle schematics and PCB layout files. It should fit the freemium version of Eagle

minDUINO-V1.5-Eagle-Preview_25-600x590

Steve Smith G0TDJ of ProjectAVR writes:

The minDUINO is designed to be easy to assemble, so it is a two layer through-hole design, not SMD. It has headers for FTDI, ISCP and port breakouts. Another project I designed was VAYU-NTX, a High Altitude Balloon Tracker. As expansion for this, I designed two small daughter boards for experimenting with. I followed a similar idea with the minDUINO and placed the breakout headers together. Later on, I may design a bespoke board but its just as easy to use stripboard/perfboard paired with the appropriate header socket.

The Ultimate Altimeter is a super-compact, Arduino controlled altimeter capable of measuring the altitude with an accuracy of 0.3 meters, and saving the highest and lowest values it has measured. It is powered by a 40 mAh Lithium Polymer battery, uses a tiny LCD Bubble Display, and measures altitude with a MPL3115A2 Altitude Sensor. It’s very simple and fairly easy to build with just six major components. Additionally, an optional 3D printed case can house the Altimeter.

The WifiDuino is the chip-sized Arduino + Wi-Fi + 128×64 OLED at low price that is easy to use.

WifiDuino is an open-source Arduino-compatible, wifi-enabled board. It allows users to use Arduino IDE (Integrated Development Environment) interface to write programs directly, and with Wi-Fi function. WifiDuino is user friendly, get started in no time. What’s different from Arduino Wi-Fi shield is that WifiDuino is a lot smaller in size, cheaper and easier to use.

WifiDuino is an open source project, which means you are welcome to develop and improve the project if you want. It is also ideal for beginners too. WifiDuino and Arduino are used the same chip. You can quickly learn how to make things with WifiDuino with its rich library resources from the Arduino database.

Let me set this up for you: most 8-bit AVRs in the wild (I happened to use an Arduino Nano for this project) are running at 16 MHz. That’s 16,000,000 calculations per second… a very respectable number for most embedded applications.

The VGA industry standard, which is pretty much the default case “we-can-always-fallback-to-this” video standard (640 pixels wide by 480 pixels tall by 60 frames per second), requires pixels to be clocked out at 25.175 MHz:

25,175,000 > 16,000,000.

And that was just one of the barriers to pulling off this silly project. And, yes, with the hack I told you about last time (Please see my notes below), more is possible without overclocking the Arduino – roughly 800 or so pixels wide in 4 bit color should be doable with a 16MHz part, and, probably 1024 pixels in 4 bit color are in reach for 20 MHz clocked parts. (If you’re willing to drop to 2 or 1 bit color and spend a ton on ICs that can handle even faster clocks, you can hit HD resolutions – but I think you’ll run into financial constraints before you max out on the technical side)

PWM or pulse width modulation is a very common method used for controlling the power across devices like motor, light etc. In PWM method the power across the load is controlled by varying the duty cycle of the drive signal. More the duty cycle more power is delivered across the load and less the duty cycle, less power is delivered across the load. A hex keypad is used for controlling the speed. The speed can be varied in seven steps using the hex keypad. Arduino UNO is the type os arduino development board used in this circuit. The circuit diagram of the PWM motor speed control using arduino is shown in the figure below.

Add a video monitor to your arduino via serial !! You can use it as your prefered output or as a secondary screen for the results of your sketch.

All you send through the serial will be printed out on your TV screen. (You can use an old TV).

On Arduino, you must connect TX from arduino to RX (blue borne) of this my rig adapter. Or on a PC, you can connect direct via USB cable.

blend

Blend Micro is an Arduino development board with built-in Bluetooth 4.0 Low Energy (aka BLE or Bluetooth Smart) connectivity targeted at developers using the Arduino platform to design IoT applications. The board uses an Atmel ATmega32u4 micro-controller and the Nordic nRF8001 BLE chip.

The Blend Micro runs in the BLE peripheral role only, allowing BLE central role devices to establish communication.
