Nooelec Oscilloscope DIY Kit w/ Clip Probe, Replacement for DSO138. Low Cost Digital Storage Oscilloscope with 2.4 TFT LCD

DSO138 was designed as a training oscilloscope kit. Simplicity in structure and easiness in assembly/operation are among the main targets of the design. For these purpose DSO138 uses mostly through-hole parts. The heart of DSO138 is a Cortex-M3 ARM processor (STM32F103C8) from ST. It uses 2.4-inch TFT LCD (320 X 240 dotmatrix, 262K colors) as its display element and displays nice and clear waveforms. Detailed assembly instructions are provided, along with a troubleshooting guide and schematic. Source code is also available to allow user to add their own features. This DSO13803K kits have all the SMD parts pre-soldered. The MCU has been pre-programmed and no re-programming required. Major features of DSO138: Analog bandwidth: 0 - 200KHz Sampling rate: 1Msps max Sensitivity: 10mV/Div - 5V/Div Sensitivity error: < 5% Vertical resolution: 12-bit Timebase: 10us/Div - 500s/Div Record length: 1024 points Built-in 1KHz/3.3V test signal Waveform frozen (HOLD) function available NOTE: 9V DC power supply required. Not included. NOTE: Assembly and soldering required.

when we add light to the environment, that has the potential to disrupt habitat, just like running a bulldozer over the landscape can.”
— chad moore, formerly of the national park service

for billions of years, all life has relied on earth’s predictable rhythm of day and night. it’s encoded in the dna of all plants and animals. humans have radically disrupted this cycle by lighting up the night.

plants and animals depend on earth’s daily cycle of light and dark rhythm to govern life-sustaining behaviors such as reproduction, nourishment, sleep and protection from predators.

scientific evidence suggests that artificial light at night has negative and deadly effects on many creatures including amphibians, birds, mammals, insects and plants.

nocturnal animals sleep during the day and are active at night. light pollution radically alters their nighttime environment by turning night into day.

according to research scientist christopher kyba, for nocturnal animals, “the introduction of artificial light probably represents the most drastic change human beings have made to their environment.”

“predators use light to hunt, and prey species use darkness as cover,” kyba explains “near cities, cloudy skies are now hundreds, or even thousands of times brighter than they were 200 years ago. we are only beginning to learn what a drastic effect this has had on nocturnal ecology.”

glare from artificial lights can also impact wetland habitats that are home to amphibians such as frogs and toads, whose nighttime croaking is part of the breeding ritual. artificial lights disrupt this nocturnal activity, interfering with reproduction and reducing populations.

artificial lights can lead baby sea turtles to their demise

sea turtles live in the ocean but hatch at night on the beach. hatchlings find the sea by detecting the bright horizon over the ocean. artificial lights draw them away from the ocean. in florida alone, millions of hatchlings die this way every year.

artificial lights have devastating effects on many bird species

birds that migrate or hunt at night navigate by moonlight and starlight. artificial light can cause them to wander off course and toward the dangerous nighttime landscapes of cities. every year millions of birds die colliding with needlessly illuminated buildings and towers. migratory birds depend on cues from properly timed seasonal schedules. artificial lights can cause them to migrate too early or too late and miss ideal climate conditions for nesting, foraging and other behaviors.

ecosystems: everything is connected

many insects are drawn to light, but artificial lights can create a fatal attraction. declining insect populations negatively impact all species that rely on insects for food or pollination. some predators exploit this attraction to their advantage, affecting food webs in unanticipated ways.
