A Shelter so High! (Ladakh Pashmina Insulation & Rebo Tent Lab)
Source: Stemoto Original
Travel to Leh & Ladakh (14,000 ft cold desert) with the Changpa tribe. Construct a Changpa Rebo tent model made of Yak hair/Pashmina wool and measure internal thermal insulation with DS18B20 temperature probes.
Categorisation
Props & Materials Required
- •Mini Changpa Rebo tent model (Yak hair/wool fabric, wooden poles)
- •2x DS18B20 digital temperature sensor probes (Inside & Outside tent)
- •Ice block cold chamber (simulates -10°C sub-zero Ladakh cold)
- •ESP32 controller board
- •16x2 LCD display screen
- •DFPlayer Mini MP3 module + 3W speaker
Step-by-Step Instructions
Place Rebo Tent in Cold Chamber
Place the Rebo tent model inside an ice-packed cold box (-10°C).
Insert Temperature Probes
Place Probe 1 outside tent (-10°C) and Probe 2 inside tent.
Track Internal Heat Retention
Warm stove inside tent keeps internal temperature at +18°C! LCD displays 'Temp Delta: 28°C Insulation!'.
Pashmina Wool Story Audio
Speaker narrates: 'Yak hair woven Rebo tents protect Changpa nomads from freezing mountain winds! Pashmina wool is 6 times warmer than sheep wool!'
Why It Works & Notes
A Shelter so High! explores high-altitude Ladakh life — cold deserts, Changpa nomads, Pashmina goats (whose wool is 6x warmer than human hair), and Rebo tents woven from Yak hair. Testing thermal insulation under freezing cold proves native engineering.
