Fred Hoefler has developed a Raspberry Pi-powered motorised assistant for a hand weaver. The problem with hand weaving is that it is hard on the hands and arms and older weavers are often unable to continue their work due to the ravages of old age. Hoefler’s solution is to add several 12V motors with a Raspberry Pi acting as the brains. Machines like this are already in existence, but can cost around $10,000. So, he set himself the task that no single component in the project should cost more than the Pi itself! The whole build came in around $200. Very impressive!
