GrowControl.com - Computer Automated Hydroponics Plantduino Greenhouse | Revolt Lab Introduction: This project is in the instructables microcontroller contest. If you enjoy it, please vote here! If we win we will begin construction on a solar earth roving robot. Disclaimer: This project uses high voltages! This is the new schematic for DC relay control: The battery is over 12 volts. My name is Clover and I am in love with vascular plants and robots. This summer I wanted to combine my two loves of plant science and engineering. I have constructed an automated watering and temperature system. I want to document this project on Revolt Lab so that anyone who is also in love with vascular (or nonvascular) plants can join me and we can nerd out together! Step 1: Plant Science One facet of this project is to grow my own vegetables and do some scientific experiments. Greenhouses There are a lot of reasons that I am building a greenhouse. Greenhouses can be made of glass or plastic. The stem of the plant grows from what is called the coteledon in the seed. Iron Deficiency Like this:
The Open Source Greenhouse Control System List of parts - GardenBot Parts This page is here to serve as a guide to locating the various parts you will need for this project. Some parts you will be able to locate at a local hardware store (or similar). Other parts will have to be ordered online. There are some brief descriptions of things of note, and there is a price sheet just to give you a rough estimate. This page also features basic explanations of some of the kinds of parts you will be working with. GardenBot software package The GardenBot software package is currently not supported. Download the old package - (2011-01-13) Arduino is an open-source microcontroller. Arduino is used as the brain of the GardenBot system. The official Arduino website You will want to start with the "Getting Started" link at the top. You don't need to wait to be a Jedi master to start your GardenBot project. Heat shrink tubing is very useful, especially when you are trying to integrate electronics into dirty environmetns like the garden. Bread-boards and Proto-boards
USBtinyISP This is documentation for a simple open-source USB AVR programmer and SPI interface. It is low cost, easy to make, works great with avrdude, is AVRStudio-compatible and tested under Windows, Linux and MacOS X. Perfect for students and beginners, or as a backup programmer. The project is based off of the USBtiny code & design. You can build this design using the schematic and firmware, or buy a kit from the Adafruit webshop. All the firmware code is distributed under the GPL, the hardware design layout files are CC 2.5 Attrib. Easy to make Ultra low cost: programmer is $16 in parts, less than half the price of the AVRISP v2 ! Easy to use AVRdude compatible - support for usbtiny added in v5.5! Easy to power Powered off of 5V USB bus at less than 100mA to allow it to be used with unpowered USB hubsEasily accessable jumper to power target project off of USB (target must be 5V tolerant, of course)Remove the jumper and it will self-power but buffer the I/O to match the target device.
Programador USB para microcontroladores AVR atmel Hola compañeros de UCONTROL, en este caso les traigo algo que quizás les sirva a muchos. Se trata de un programador USB para la línea de microcotroladores AVR. Esta herramienta es un clon del programador USBtinyISP que está publicado en esta página: Las únicas modificaciones importantes que he realizado con respecto al programador que se muestra en la página, son las siguientes: * Circuito impreso a una sola cara para fácil armado por parte del hobbysta inexperto. * Eliminar buffer tri - estado 74HC125M (A veces trae problemas de comunicaciones). * Eliminar unión Self - programming (Recomendado en la página oficial del programador). El programador es multiplataforma por lo que tiene soporte en todos los sistemas operativos vigentes: * Windows XP, vista, Seven ( Versiones 32 y 64 bits )...yo lo he probado con Windows XP y Seven de 32 bits y funciona correctamente. * Linux Ubuntu. * MAC OS v9 en adelante.
ISP Learning Examples | Foundations | Hacking | Links Usando Arduino conmo un AVR ISP (In System Prgrammer) Este tutorial explica cómo usar una placa Arduino como un AVR ISP (In System Prgrammer). Esto te permite usar la placa para programar el bootloader a Microcontroladores AVR (por ejemplo los ATmega168 o ATmega328 usados en Arduino). Instrucciones Para usar tu placa Arduino para progamar el bootloader a un microcontrolador AVR tienes que seguir estos simples pasos. Carga el programa ArduinoISP (en Ejemplos) a tu placa Arduino Conecta los cables desde tu placa Arduino a la placa que quieres programar como se muestra en el diagrama de abajo. Circuito Una placa Arduino actuando como un ISP para programar el ATmega a otra placa Arduino. En placas NG o más antiguas, conecta el cable de reset al pin 1 del ATmega en la placa, como se muestra arriba Un Arduino ISP para programar un ATmega sobre placa de entrenamiento.
Fluid-Level Sensor Parts List: R1 = 470K N1,N2 = MC14093B R2 = 15M* T1 = 2N3906 (these will work also: PN200, 2N4413) C1-C4 = 2N2 (2.2nF) (NTE159, ECG159, BC557, BC157, TUP) D1 = 1N4001 Ry = Relay (12V or matching supply voltage) D2,3 = 1N4148 Sensor = Stainless Steel probes, brass, chrome, etc. The above circuit uses an AC-sensing signal to eliminate electrolytic corrosion on the probes. The AC signal is rectified and used to drive Transistor T1 that drives the relay. The relay is a 12-V type of your choice. Please note: Unused inputs MUST be tied to an appropriate voltage level, either ground or +12V. The "RESET" switch in the circuit is optional. Below are a couple valuable comments from Dave Burton of Burton Systems Software: Thanks, Tony, for publishing your Fluid-Level Sensor design. Also, it says "the 'Sensor' works via the capacitive method." But to detect dirty water or tap water you can use almost anything: even a pair of bare wire ends several am apart works just fine.
Soil Moisture Tester Circuit For those of us who don’t like to get their hands dirty, this simple soil moisture tester quickly checks the state of their plants and how much attention they need. Recommended for all plant owners! Plants seem to have something in common with pets. So what can we do about it? The circuit described here might be very simple, but it’s a very useful soil moisture tester. A quick look at Figure 2 is enough to ascertain that the full circuit is barely more complex than the block diagram. The preset used to set the sensitivity can be found as P1. Pin 9 is used to set the display to bar-mode or dot-mode. Moisture tester construction Due to the small number of components used, it’s unlikely that the construction of the tester will give you sleepless nights. The small mains transformer (Tr1) is mounted onto the PCB last. Moister measure PCB layout The circuit should be mounted in a safe plastic case, with a label stuck on the bottom, stating the mains voltage and the value of the fuse.
Plant soil moisture meter and automatic controller circuit I like planting trees, because trees are more useful to us. However, I always have problems with moisture content of soil,Each plant needs water is not as same. Watering or soil moisture is not good. 1. A trees should be taken care of as well. 3. This Check this dry soil circuit or soil moisture meter For the Blind. 4. Today we try to build warn the moistness or Moisture Activated better. 5. Electronic users love trees. Build This DIY Moisture Monitor and Never Kill Another House Plant My perennials always died because I watered them too little or too much, or put them somewhere too dark or too hot. Recently I vowed to keep my plants alive, so I turned to Arduino. I'd been looking for an excuse to try out this microcontroller platform, which I knew could be programmed to do a lot of cool things. What You'll Need • Bolts, nuts, ring terminals ($5) • Arduino Uno ($28) or Arduino Uno Starter Kit ($100), which includes the following parts: • Solderless breadboard ($5) • Assorted wires ($7) • Thermistor ($2) • Photoresistor ($1) • 10K-ohm resistors ($8 per pack) • Potentiometer ($1) • LCD display ($10) Getting Started Arduino uses open-source hardware and software, so I was able to borrow ideas from other well-tested devices. I found instructions for several Arduino-based plant sensors online, including the GardenBot, the ArduGarden, and a solar-powered sensor that measures soil fertility and weather conditions. You can buy all the parts separately for less than $70. Code:

Cultivo de autoflorecientes: Consejos, variedades y trucos Lo primero hablando de cultivo de semillas autoflorecientes es hablar de las horas de luz necesarias para esta genética tan especial. Tras muchas pruebas con distintos fotoperíodos de luz, llegamos a la conclusión que la mejor decisión es utilizar durante todo el ciclo de la planta un horario constante de 20 horas de luz + 4 de oscuridad. Bajo nuestro punto de vista es la opción que nos ofrecerá mejores rendimientos por ciclo mejorando de largo el clásico ciclo e 18/6 del crecimiento + 12/12 para floración. Las semillas automáticas suelen ser un ejemplo de buena y rápida germinación sorprendiendo incluso a cultivadores con mucha experiencia por lo breve del proceso. Por lo general, las semillas autoflorecientes, son genética rudelaris pura, o híbridos de rudelaris con cannabis indica o sativa según el caso. Para el cultivo en interior recomendamos el uso de macetas de 5,5 litros o un máximo de 7 litros. Consejos, tutoriales y trucos o utilizando el link a continuación: www.santyerbasi.com
Plantas autoflorecientes de marihuana, evolución y revolución La particularidad de estas plantas es que no necesitan determinadas horas de luz para florecer. Florecen haya la luz que haya, tanto muy poca como mucha. Si tienen carencias de luz, dan muy pocas flores, si la luz abunda, hoy en día los cogollos pueden ser muy generosos. Se adaptan prácticamente a cualquier clima y/o latitud. Hace escasos años, cinco o diez, muy poca gente confiaba en el potencial de las plantas autoflorecientes de marihuana para conseguir hierba de calidad. La calidad de las plantas autoflorecientes comenzó aquí su revolución. Unos pocos breeders en Europa, viendo el potencial que tenían estas plantas, empezaron a trabajar con ellas, haciendo cientos de cruces, pruebas, retrocruces; a veces acertando y otras fracasando en el intento de conseguir plantas autoflorecientes de máxima calidad, tamaño, sabor, resina y estabilidad. ¡Por fin se conseguían autoflorecientes feminizadas con una calidad aceptable!
