Dso138 oscilloscope
DSO138 was designed as a training oscilloscope kit. It contains only the basic oscilloscope functions with no fancy features. Simplicity in structure and easiness in assembly/operation are amongst the main highlights of the design. For these purposes, DSO138 uses mostly through-hole parts. The heart of DSO138 is a Cortex-M3 ARM processor (STM32F103C8) from ST. It uses a 2.4-inch TFT LCD (320 X 240 dotmatrix, 262K colors) that displays crisp and clear waveforms.
DSO138 is partially open-sourced. This opens the possibility for users to add different features or develop new applications on the hardware.
Major features of DSO138:
Analog bandwidth: 0 – 200KHz
Sensitivity: 10mV/Div – 5V/Div
Sensitivity error: lessthen 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
Save/recall waveform

যারা মেইল করবে তারা মেইল করারা পর অবশ্বয় কমেন্ট করে জানাবে, তাহলে আমার জানতে সুবিধা হবে, আর পাওয়ার পর আবার কমেন্ট করে জানাবে যে পেয়েছ,
মেইল এর নাম আর ইউটিউব চ্যনেলের নাম যেন এক হয়, আর না হলে চ্যনেলের নামটি মেইলে বলে দেবে, নইত কমেন্টে,
আর যদি ইনবক্স এ না পাও তবে স্পাম এ মেইল পাবে,
আর বাকি কাজ গুলো করতে ভুলবেনা!

W1209 Temperature Controller P0 to P6, Full Function Review.
W1209 Temperature Control Switch. SPECIFICATION: Temperature Control Range: -50 ~ 110 C Resolution at -9.9 to 99.9: 0.1 C Resolution at all other temperatures: 1 C Measurement Accuracy: 0.1 C Control Accuracy: 0.1 C Refresh Rate: 0.5 Seconds Input Power (DC): 12V Measuring Inputs: NTC (10K 0.5%) Waterproof Sensor: 0.5M Output: 1 Channel Relay Output, Capacity: 10A Settings Chart Long press the “SET” button to activate the menu. Code Description Range Default Value P0 Heat C/H C P1 Backlash Set 0.1-15 2 P2 Upper Limit 110 110 P3 Lower Limit -50 -50 P4 Correction -7.0 ~ 7.0 0 P5 Delay Start Time 0-10 mins 0 P6 High Temperature Alarm 0-110 OFF Long pressing +- will reset all values to their default Displaying the current temperature: The thermostat will display the current temperature in oC by default. When in any other mode making no input for approximately 5 seconds will cause the thermostat to return to this default display. Setting the trigger temperature: To set the trigger temperature press the button marked 'SET'. The seven segment display will flash. You can now set a trigger temperature (in oC) using the '+' and '-' buttons in 0.1 degree increments. If no buttons are pressed for approximately 2 seconds the trigger temperature will be stored and the display will return back to the current temperature. Setting the cooling or heating parameter P0: The parameter P0 has two settings, C and H. When set to C (default) the relay will energise when the temperature is reached. Use this setting if connecting to an air-conditioning system. When set to H the relay will de-energise when the temperature is reached. Use this setting if controlling a heating device. Setting the hysteresis parameter P1: This sets how much change in temperature must occur before the relay will change state. For example if set to the default 2oC and the the trigger temperature has been set to 25oC, it will not deenergise until the temperature falls back below below 23oC. Setting this hysteresis helps stop the thermostat from continually triggering when the temperature drifts around the trip temperature. Setting the upper limit of the thermostat parameter P2: This parameter limits the maximum trigger temperature that can be set. It can be used as a safety to stop an excessively high trigger temperature from accidentally being set by the user. Setting the lower limit of the thermostat parameter P3: This parameter limits the minimum trigger temperature that can be set. It can be used as a safety to stop an excessively low trigger temperature from accidentally being set by the user. Setting temperature offset correction parameter P4: Should you find there is a difference between the displayed temperature and the actual temperature (for instance if the temperature probe is on a long run of cable) you can make minor corrections to the temperature reading with this parameter. Setting the trigger delay parameter P5: This parameter allows for delaying switching of the relay when the trigger temperature has be reached. The parameter can be set in one minute increments up to a maximum of 10 minutes. Setting the high temperature alarm parameter P6: Setting a value for this parameter will cause the relay to switch off when the the temperature reaches this setting. The seven segment display will also show '---' to indicate an alarm condition. The relay will not re-energise until the temperature falls below this value. The default setting is OFF.
