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

H8 micro mouse robot

Check this out – small cute robot that is equipped with multiple sensors that allow it to navigate around various obstacles. Despite its small size it is controlled by some sort of RTOS so called HOS, which takes care of ultrasonic sensors, stepper motors and LEDs. It has two main modes: turning mode when obstacle is detected and speed-up mode when micro mouse robot speeds up until finds another obstacle. Project description is written in Japanese language, so you might need some sort of online translator like google. Continue reading

Outdoor robot power system

This one is Great and Practical project. Outdoor robot power system is tended to be a gas engine based small power plant for mobile outdoor robots. It uses a car alternator shafted to Honda mini 4-stroke engine (GX35). Power plant has some electronics that assures proper power generation: Alternator current/voltage regulator. Regulator allows to control(limit) field current with external resistors and even charge a battery with shut off feature if 14.5V is attained. Throttle controller. This part is based on SX28AC/SS parallax microcontroller which has to relate Engines throttle with output current. This system allows to control engines RPM so that battery weren’t overcharged and optimal power is provided. Building such system requires some skills including mechanical, electronics and even programming MCU. Just remember this is an outdoor mobile power plant – do not try to use or test it indoors as it provides a CO gas exhaust that is poisonous. Continue reading

Pet Porte – Your New Cat Savor System

Cats had been recognized as the most commonly pet in household. According to the pet survey, cats and dogs are the top two favorite pets that mostly rear by peoples in their home. The reason why peoples love these two kinds of animals, is mainly related with the loyalty for their master (dogs) and the elegant and its always laid back behavior (cats) Having cats with a pet or partner is a pleasure experience, as we can learn their daily life habits, behaviors, body languages and their socialization. However, some of the cat lovers facing many problems rearing cats and this can greatly become a great headache for them. Some of the matters that currently turn into major problems to cat lovers: There always so stray cats that break in to your house, crunching and feast themselves with your cat’s food. Those neighbor cats always become annoying intruders and messing up your home. Hate of washing those “little gift” (The disgusting pooh or urine) left by the stray or neighbor cats. From now on, you can waive goodbye to the… Continue reading
