a quick visit @strawberry farm after lunch on saturday. collecting some and eating more of these sweets๐Ÿ˜ no electronics today... #erdbeerland #erdbeere #strawberry #strawberryfarm #villach #villachererdbeerland #erdbeerlandgoritschach
this is one multichannel sensornode as prototype pcb  with ATmega328 used in a node grid network.... pcbs just arrived... assembly was done quickly by hand now and flashing the testcode... to commuicate with some arduino Unos

vintage tape recorder Toshiba KT-270D. this cassette recorder from the year 1973 was manufactured by Tokyo Shibaura Electric Company in Japan... this device is still working today... only thing to replace is the belt.

this is really vintage - an old cable clamp used in house wiring. i guess it's from the 60ies or earlier. this clamps wires up to 4mm^2 and is made of bakelite.

a cool thing for videoproductions - the wireless microphone transmitter-receiver from rode called rodelink. can be used with any camerasystem with external microphone input. 3.5mm or xlr connectors. i use it with dji osmo, panasonic and canon dslr camera....

an easy way to make a water boiler heating system  compatible for a pv (photovoltaic) if you want to set the power it consumes... just build a simple phase angle controller... this is the test setup๐Ÿ˜Š the trashcan filled with water simulates a small boiler... the heater is the black device and some thermosensors to measures the water and surface temperature  to calculate the thermal energy on different powersetings...

good old analog circut technology with operational amplifiers... how to handle a signal coming from a whatever-sensor... capture the signal with an oscilloscope, analyze its behavioral - think about how to process it - calculate - simulate with LTspice and make a simple test board. then compare the results of simulation with the measurements...
