AS7010 STMeter – The Handheld Installation Tool

You’re in search of a handheld installation tool, but you couldn’t find what you’re looking for until now? Oh well, you should stop for a while and have a closer look on this AS7010 STMeter, as it might be the thing that you’ve searching for a long time! The AS7010 STMeter is based on PIC16F877, as it provided sufficient I/O pins to drive an LCD and interface to the keypad. Beside that, the PIC16F877 contains a UART and ADC as well. Hence, the power can be supplied by the maintenance port of the Subscriber Terminal via a step down regulator. For your information, the AS7010 STMeter is connected to the ST Antenna Unit to give the following information: The Visual antenna panning aid in the form of a bar graph (It indicates received signal level automatically) The Numeric Receive and Transmit levels The Numeric Carrier to Interference levels RF channel number and PN code When you’re attaching the STMeter to the ST maintenance port, the UART will be used to pass information to the main ST processor using a SLIP… Continue reading

Seeker II – The Interactive Mini-Sumo Robot

For those that always involved themselves in the “Mini-sumo competition”, the Mini-sumo robot is very common to the developers. No matter you’re the amateur or the professional in the robotic development field, this Seeker II is going to amaze you here! For your information, this Seeker II is a low, fast and very aggressive mini-sumo robot, where is equipped with wide tires that provide a lot of traction than other mini-sumo did. The Seeker II’s brain is based on a Microchip PIC16F876 and is programmed in C language. Beside that, there PIC16F876 have several useful features, such as: It has two-channel hardware pulse width modulation (PWM), which is mainly for providing precise control over the speed of the two motors. Four analog to digital converters (ADC) are used to interface to two range-finder and two edge-detector sensors. A 16 bit hardware timer (It increments a 35 bit integer millisecond counter). The hardware UART, where is used to program the PIC using the bootloader and to run a menu-driven debug system. The EEPROM is used for a simple log to show… Continue reading

The Versatile Development Board for AVR microcontrollers ATmega48/88/168

For those of you here that always involved yourself with the AVR microcontrollers, have you ever wished to build a multipurpose development board that compatible with all type of AVRs microcontrollers, such as ATmega48, 88 or 168? Well, you can simply use this board for testing and debugging embedded programs since it has many built-in peripherals connected to microcontroller. Thus, you can use them without even a further soldering or modification! Ok, I know it sounds unnecessary here, but for those that never ever used any ATmega microcontrollers before, you should know that they have many great features, which as: Easy to adjust I/O, Timers, PWM generators, ADC, RS232, TWI, SPI, Analog Comparator, Osillator, EEPROM etc. The main reasons why you should use these microcontrollers because they’re very versatile, easy to program and having an easy to use interface as well! Since this development board has been specially designed, thus you can apply it to use with ATmega (4kB), Atmega (8kB) or ATmega (16kB). Hope you will enjoy this development board project and until then, see ya! Continue reading

Would You Mind to Have a Portable Universal Radiation Spectrum Analyzer?

Do you know what is the heck of this “URSA” was? Well, URSA is stands for “Universal Radiation Spectrum Analyzer” and it’s a very useful tools, which we can simply applied it into the: Bulk sample analysis Air sample analysis Wipe sample analysis Environmental monitoring Remote monitoring Portal monitoring Nuclear medicine Health physics Thyroid assay Homeland defense You can determine the quality of a URSA, by simply refers to its low noise design feature. The lower the noise level will constantly allows much higher gains to be used. In addition, the noise level will also greatly affect the detection of peaks at the very low end of the spectrum as well. Below here are some of the key characteristics for a high quality URSA: The low noise design (the lower the better), good low end resolution. Exceedingly Fast response, even for short counting times. The stand alone feature means no need to relate with other tools for operation. The Onboard 256K Byte memory (this for the storage of 4096 channel spectra). The 16 full spectra with 32 bit count per… Continue reading
