I have some strong opinions about fashion. Despite wearing the same monochromatic outfit to work nearly every day, Im a fan of sartorial elegance, tailored suits. Here we are presenting a long range FM transmitter that can cover a reasonable distance of 5 kilometers 3 miles and beyond with a one watt RF power with full.

Development Board, it is first necessary to have a 1. Plug In Module PIM installed on the male headers U1. A. A PIM is always required, as the microcontroller U1. PIM area is part of the PICkit On Board programmerdebugger circuit, and is therefore not intended for running application related code. A list of available 1. PIMs which are compatible with the Explorer 1. Explorer 1. 6 Development Board can be found at http www. To begin development and programming the PIM microcontroller and using the hardware of the Explorer 1. Development board, it is recommended to obtain the MPLAB Integrated Development Environment IDE and a suitable C compiler supporting your desired target PIM microcontroller. MPLAB X IDE and MPLAB C compilers can be found at http www. Microchip provides a wide variety of free example firmware projects and libraries, which are compatible with the Explorer 1. Development Board. Some initial out of box demo projects are available from http www. Explorer. 16. 32. These demos exercise and demonstrate the basic functionality of the Explorer 1. Development Board and the microcontroller e. ADC data to the LCD module. Details on the usage of the example projects can be found in the documentation accompanying the projects. Application and microcontroller peripheral interface code can be generated using the MPLAB Code Configurator MCC http www. Additional reference projectslibraries compatible with the Explorer 1. Development Board can be found in the Microchip Libraries for Applications MLA and Harmony packages http www. Harmony. Tips for Reading the Schematics. The net names of signals connecting to the PIM microcontroller headers U1. A follow a naming convention where each net except power and ground is prefixed with Pxx where xx is a number 1 1. The Pxx number corresponds with the U1. A male PIM header pin number associated with the net. Nets that are also connected to one or more dedicated hardware features on the Explorer 1. Development Board have net names with underscores and suffixes denoting their associated features. For example, the net P2. TEMP is the electrical signal attached to the U1. A male PIM header pin 2. TC1. 04. 7A temperature sensor U4 on the Explorer 1. Development Board. Similarly, the net P9. S5LED1. 0 represents the signal attached to U1. A male PIM header pin 9. S5, as well as LED D1. Explorer 1. 63. 2 Development Board. It is important to note that the U1. A male PIM header pin numbers usually do NOT correspond 1 1 with the pin numbers of the microcontroller mounted on the PIM PCB. For example, the PIC2. FJ2. 56. GA7. 05 PIM MA2. TQFP 4. 8 microcontroller, which does not have enough total IO pins to connect to and control all 1. PIM pins independently especially in a 1 1 fashion. Therefore, the PIM PCB maps microcontroller pins to PIM header pins on a functional basis ex PIM pin 2. P2. 1TEMP is connected to an AD input channel pin RA1AN1 on the microcontroller, which is TQFP 4. Download Sherlock Holmes Song'>Download Sherlock Holmes Song. We recommend you refer to both the PIM schematics as well as the Explorer 1. Development Board schematics when tracing signals between the microcontroller IO pins and the connected hardware. In addition to the above conventions, the signal names for dedicated signals connecting to the mikro. BUS interfaces end in A or B. For example, the net P1. SCKA connects to U1. Build a Huge 7 Segments 8 Digits Red LED Display 1. Steps with PicturesThis instructables presents how to make a huge 7 segments 8 digits LED display panel. The purpose of this display is to display the time, date, temperature or to be used as a chronometer at various running contests, mountain bike contests, trail running contests and so on organized by NGOs with low budget. The display may show elapsed time hours, minutes, seconds and hundreds of a second. In order to use the display, a microcontroller or digital interface is needed and this is above the scope of the current instructable. The display may work as a stand alone device driven by a microcontroller Arduino stuff or may be driven by a PC laptop interfaced by some discrete digital logic. Design constrains requests to be big enough to be readable from 2. LEDs low electrical power consumption to use feasible and long lasting light emitting devices to withstand to harsh environment some contests may be during fall, winter times, during rain, strong sun to be light and sturdy in the same time  it has to be carried from point A to B to have a reasonable size in order to fit on regular vans or on the roof of a car it must be carried from a location to another to show hours, minutes, seconds and miliseconds hundreds of a second as a chronometer to show as well the temperature negative and positive, local time and current date to separate the pair of digits by   2 separation dots to allow multiplexing of segments and digits and separate control of minus and separation points to have a reasonable cost to involve a reasonable amount of work to look nice. Based on these requirements, my choice was to use red LED strips for 1. Vdc these are comming in reels and you can cut the desired length, polycarbonate panels and a wooden frame. All the LEDs were connected using cheap network cable 8 wires inside, full copper. The LEDs were connected to form 7 segments per digit and 8 digits 6 digits are big size and 2 digits are small size these 2 digits are used to display hundreds of a second. Also in front of the first digit is a big minus sign for negative temperatures and between each pair of digits are 2 separation dots. Boss Side Loader Manual on this page.

Unfortunately at the moment of building this huge 7 segments 8 digits LED display I didnt take too many pictures, I had no intention to share that experiment, but now I realized that it may be interesting for others as well. Due to this reason, the instructable did not documented with pictures each detail, some of the existing pictures are not the best or the most explicit, so you need to understand my English or to imagine another way of performing the same operation. Or simply to ask where you dont understand Lets start 2. Edit LED stripes LED strips see comments for more explanations.
