Repair and Troubleshooting Electronic Equipment and gadgets.

“Strippenstrolch” is thus a pitch name for “electricians”. here you can also see a innovative project that combines rainwater harvesting and a solar energy operated pump to flush toilets.

“In Germany one finds this designation now and then for an electrician on the work. Particularly in the winter, if it is still dark in the morning, one often sees “Strippenstrolche” with its building lamp on the building site:”

Combination of Rain and Sun Harvesting

“The inspiration for a self-sufficient toilet flush was now close at hand: I thought at first to work with a power supply that provides me the 12V to the pump. But as a power supply would idle constantly consume energy, I rejected this solution. I have long experimented with solar power, so I decided, now a solar system for our toilets to build. On the flat roof of our garage I installed two 12V – 55Wp – solar – modules (Conrad Electronics). This I switched in parallel.”

“As a solar storage currently serves an ordinary car battery 45Ah (later 3 pieces with a total of 135 Ah). The charging control acquires an 8A charge controller (Conrad). So all very simple.”

This is a Article by Conrad Hoffman in “Electronics Now, April 1996”.He has an intriguing collection of electronics and Mechanical DIY Tips and Ideas in his site.

His “Electronic Mess” section has many pages on repairing and restoring old instruments and equipment.

An Excerpt from his pages is a Reading Pleasure due to his rich experience and enticing language.

Troubleshooting Audio Electronics

I ain’t gonna lie. You won’t be a master troubleshooter after reading a couple pages here. Hopefully, what I can do is give you the ability to form a logical plan of attack.

Troubleshooting is done mostly with the mind, not with the soldering iron. We all have problems that get the better of us, at least for a while, but approaching the situation as an interesting puzzle, rather than an unpleasant task to be suffered through, will make the work go quickly.

Success will come from a 3-prong approach, a combination of understanding the circuit, having the means to test it and being in the right frame of mind to correctly interpret the test data. Never underestimate that third component.

He also has a Design and Testing Services called Deep Run Design.

“The idea is to expand on a simple LED tester by allowing the user to plug in an LED, dial in the LED brightness, and then read information on an LCD showing the LED voltage drop, the current current, and the value of current-limiting resistor to use in a target circuit. “
