230v-led-10ma.zip by Guenter

4 x LED zum Anschluss an 230V im Gehäuse ERNI IDG-B2 für Hutschienenmontage. Der LED Strom wird durch Kondensatoren auf ca 10mA begrenzt. Um ein Überstrahlen der Led zu vermeiden kann ein geeignetes Material zur Lichtführung eingesetzt werden z.B. Styrodur oder ein anderer sauber zu bearbeitenter Kunststoff.

arduino_wifi_shield_v022-rev3.1.zip by drak

The Arduino WiFi Shield connects your Arduino to the internet wirelessly. Connect it to your wireless network by following a few simple instructions to start controlling your world through the internet. As always with Arduino, every element of the platform – hardware, software and documentation – is freely available and open-source. This means you can learn exactly how it\'s made and use its design as the starting point for your own circuits. -Requires an Arduino board (not included) -Operating voltage 5V (supplied from the Arduino Board) -Connection via: 802.11b/g networks -Encryption types: WEP and WPA2 Persoanl -Connection with Arduino on SPI port -on-board micro SD slot -ICSP headers -FTDI connection for serial debugging of WiFi shield -Mini-USB for updating WiFi shield firmware

lm380.zip by xtronic

The LM380 is a power audio amplifier for consumer applications. In order to hold system cost to a minimum, gain is internally fixed at 34 dB. A unique input stage allows ground referenced input signals. The output automatically self-centers to one-half the supply voltage. The output is short circuit proof with internal thermal limiting. The package outline is standard dual-in-line. The LM380N uses a copper lead frame. The center three pins on either side comprise a heat sink. This makes the device easy to use in standard PC layouts. Uses include simple phonograph amplifiers, intercoms, line drivers, teaching machine outputs, alarms, ultrasonic drivers, TV sound systems, AM-FM radio, small servo drivers, power converters, etc.

power_supply_lm317_0-25v.zip by BRedemann

Power supply module with LM317, linear voltage regulator. In order to get 0V a TC962 is added which creates the negative voltage of 1,25V for the LM317. For higher loads you need a heatsink for the LM317. The picture shows the protoype. See also my video on youtube: https://www.youtube.com/watch?v=Mq63OWvsOJw
