An Earthbag Round House For Less Than $5,000
Looking for a very stable design which does not only come cheap from the start but also makes you save money in the long run. Due to its shape and materials used, the earthbag house has less area than your normal home, so it’s cheaper to keep it supplied with energy. Don’t be scared if you never built circular structures before, because the example shown here used a technique called the compass arm which you can easily learn. Starting on the rubble trench foundation. Covering over our sediment fabric with pea gravel. Two rows of stem wall – 80 lb sack concrete. 2 strands of barbed wire go between every row. Firewood used to hold the barbed wire in place. Door frame up. A strip anchor to hold the door in place.

Chicken Jambalaya - Caribbean
Return to listing Jambalaya is one of the easiest and best rice dishes that owes its origins to the traditional Cajun cooking of America. Serves 2-3 This recipe is taken from The Delia Collection: Chicken. First of all, heat the frying pan over a high heat and brown the pieces of chorizo sausage, without adding any fat, then remove them from the pan to a plate and set aside. Then add a tablespoon of the oil and, when it's hot, brown the chicken and transfer that to the plate with the chorizo. Continue to fry for 4-5 minutes, till the celery and pepper are also softened and lightly tinged brown at the edges, adding a little more oil if you need to. Now stir in the rice to get a good coating of oil, then add the Tabasco to the hot chicken stock. Then, check that the rice is cooked and add a little more stock, if necessary.

Building a PIC18F USB device
Update I have updated this article to use the Microchip C18 compiler and to be based around my latest USB framework libraries for both the PIC and Windows (2011-10-19). This should provide a smoother path from this basic tutorial to more complex projects. As always I welcome your feedback and suggestions over in my forums. Introduction I get a number of emails every month asking about creating USB devices using the PIC18F microcontroller. In this article I will show how to breadboard a simple USB generic HID device, creating the PIC18F firmware and finally creating the Windows interface for the device which will allow you to control a LED from the PC and read the state of a push-button from the device. For this article we're going to stick to a fairly basic USB device. Although this article is based around the PIC18F4550 microcontroller you can easily substitute this for the smaller and cheaper PIC18F2550 which is code compatible with the larger 4550. Hardware Firmware Device enumeration
PIC 18F4550 | Sjriek
The Pic18F4550 is a microcontroller from the Microchip 8-bit family. This microcontroller is i deal for low power and connectivity applications that benefit from the availability of three serial ports: FS-USB(12Mbit/s), ICTM and SPITM (up to 10 Mbit/s) and an asynchronous serial port. Large amounts of RAM memory for buffering and Enhanced Flash program memory make it ideal for embedded control and monitoring applications that require periodic connection with a personal computer via USB for data upload/download and/or firmware updates.. There are currently two platform versions with this microcontroller available within the faculty. This version is based on a trough hole solder technique, and is available at the servicedesk as a DIY kit. Schematic USBPIC USBPIC mini: This version is based on a surface mounting (SMD) technique and therefore has a smaller footprint. It requires some soldering skills to assemble this one. usb-smd-microcontroller usbpic_mini_sch Example code with library functions:
ARDUINO MPPT SOLAR CHARGE CONTROLLER (Version-3.0)
After lot testing we observed that MOSFET ( Q3 ) in ver-3.0 design is burning repeatedly.We tried to modify the existing software but not find any satisfactory result. The other problem was that MOSFET Q1 ( in V-3.0) conduct even when there is no solar input. To solve the above problems and enhance the power handling capability we are modifying both the hardware and software.This is named as Version-3.1 Charge Controller. This version is not completed yet.So wait until it is complete. Don't worry we are making a solution for those who have made the V-3.0 prototype.After little modification we will able to use the new software. You can see the updates on Hackaday.com This version have 3 options. 1. 5 Amp version : T94-26 toroid, 48 turns of AWG20 wire to give 135 uH (it takes almost 1.5m of wire) Q1, Q2 and Q3 all pairs of IRFZ44N MOSFETs (6 in all). C1 will be 3 * 220 uF low ESR capacitors in parallel, C2 will be a single 220 uF low ESR capacitor 2. 8 Amp version : 3 10 Amp version :
Tiny AVR Programmer Hookup Guide
Favorited Favorite 3 The ATtiny85 isn’t your everyday Arduino IC. It packs a lot of punch for its small size, but there are some things it can’t do. On this page, we’ll provide a quick overview of the ATtiny85 as it pertains to Arduino and the Tiny AVR Programmer. Pinout Just like any Arduino board, each I/O pin on the ATtiny85 is assigned a numerical identifier. Each of the I/O pins on the ATtiny85 are capable of digital input and output. Analog Input and Output There are two analog outputs and three analog inputs. int pwmPin = 0; pinMode(pwmPin, OUTPUT); for (int i=0; i<=255; i+=5) { analogWrite(pwmPin, i); delay(5); } And use analogRead([pin]) to read an analog voltage between 0 and 5V, and turn it into a 10-bit representation of that voltage. int pwmPin = 0; int analogInPin = A1; pinMode(pwmPin, OUTPUT); pinMode(analogInPin, INPUT); int analogIn = analogRead(analogInPin); analogWrite(pwmPin, analogIn / 4); No Serial (UART). So you’re out one of the more useful Arduino debugging tools.
Off-Grid Battery Bank
Due to the fact that our domestic power consumption is peaky and most of the sources of renewable power are intermittent and uncontrollable, power must be stored to balance these conflicting concepts. Virtually the only way to store power is in the form of an off-grid battery bank. There are several different types of battery storage available, but because this is probably the most expensive component in the utility free home, it’s very important that the right choice is made. The traditional and almost universal method of storing power is in a Lead acid battery. Even with the few recent developments in lead acid battery technology (and please read the rest of this text before spending extra money on them), this power storage technology has remained fundamentally the same for the past 150 years.
