ASPI Technical Paper Series on DIY Simple Living

From 1990-2004, ASPI published a series of "Technical Papers" written by several DIY authors under the project direction of Founder Father Albert Fritsch. Each Technical Paper (TP) contains concise and informative research on many appropriate technology subjects. Ranging from DIY how-to directions to scientific reference materials, these timeless fact sheets provide valuable resources for low-cost simple living. All ASPI Technical Papers are available to download as free PDFs below!
