Ultrasonic Movement Detector

This is a simple but robust ultrasonic movement detector circuit. It also uses a crystal locked circuit to get maximum performance from the ultrasonic transmitter. However, the detection circuit is different. We think it is more sensitive.

ASSEMBLY INSTRUCTIONS

Check all the components against the parts list. It is generally easier to solder in the lowest height components first - the  esistors and diodes. Make sure to get the diodes in the correct way. The black circle or band on the diodesmust match the bar of the diode symbol on the overlay. There are a lot of resistors. Use the resistor color code printed on the back of the header card to work out each value.

The 40 kHz crystal can be inserted either way. Holes have been provided to secure its case

दुई लाईन सँघर्षपछिको यथास्थितिवाद

जुन पार्टीमा वैचारिक सँघर्ष चलिरहेको हुन्छ, वास्तवमा जीवन्त पार्टी भनेको त्यही नै हो। एंगेल्सका अनुसार विचार नियमहरूको सिद्धान्त भनेको कुनै पनि अर्थमा सदा सदाका लागि स्थापित चीर सत्य होइन। निरन्तर परिवर्तनशील र सिर्जनात्मक विकासको प्रक्रिया नै असल मार्क्सवाद हो। कम्युनिष्ट पार्टी विपरितहरुको एकत्वमा आधारित सँगठन हो न कि एकमनावादी सँगठन। त्यस कारण कम्युनिष्ट पार्टीमा जहिले पनि वैचारिक सँघर्ष चलिरहनुपर्छ र मार्क्सवादको वैचारिक परिधिभित्र रहेर आफ्ना भिन्न मतहरु स्पष्ट राख्ने कार्यलाई प्रोत्साहित गरिनु पर्दछ। विचारको विकासको क्रममा वैचारिक अन्तरसँघर्षले त्यस कालखण्डका लागि मात्रै वैचारिक ध्रुविकरण हुनु ठीक हो र सँघर्षबाट निस्कने परिणाम वा विचार जो सबैको लागि साझा हुन्छ, त्यस मार्फत नै पार्टीको कार्यक्रमलाई दिशानिर्देशित गरिनुपर्दछ। यसरी टुङ्गिने अन्तरसँघर्षले पार्टीलाई नयाँ जीवन प्रदान गरेको हुन्छ भने ध्वँसपछिको निर्माण भन्ने सिद्धान्तलाई आत्मसात

तिम्रै...

यो गजल तिम्रै थियो, यो कलम पनि तिम्रै

यो जिन्दगी तिम्रै थियो, यो साँस पनि तिम्रै।

तिमि बाहेक को नै थियो, सबै सौगातहरु तिम्रै

हरेक दिन हरेक रातहरु, हरेक प्रभातहरु तिम्रै।

मेरा खुशीहरु तिम्रै थिए, मेरा इच्छाहरु तिम्रै

मेरो जीवनको सार अनि सारा सदिक्षाहरु तिम्रै।

तिम्रै थियो आकाश मेरो, मेरो धर्ती पनि तिम्रै

मेरो आवेशका गन्थनहरु, मेरो अर्ती पनि तिम्रै।

मलाई डोर्याउने हातहरु, रमाइला साथहरु तिम्रै

ती आवाजहरु सान्त्वनाका मेरा सम्मानहरु तिम्रै।

मेरो जीवनभरीको प्रित अनि मेरा गीतहरु तिम्रै

ती मीठा अतितका सम्झना, मेरा वन्दनाहरु तिम्रै।

तिम्रै थियो त्यो बाटो अनि मेरा चालहरु तिम्रै

म सुस्ताउने ठाउँको   त्यो पर्खाल पनि तिम्रै।

मेरो यात्राको प्रारम्भ अनि अन्त्य पनि तिम्रै

सकिएन कहिल्यै पुग्न त्यो गन्तव्य पनि तिम्रै।।
