There is currently a plagiarised copy of it on the site of an Indian electronics magazine credited to a rip-off artist called Indrani Bose. This page is a guide to producing consistently high quality PCBs quickly and efficiently, particularly for professional prototyping of production boards. Unlike most other PCB homebrew guides, emphasis is placed on quality, speed and repeatability rather than minimum materials cost, although the time saved by getting good PCBs every time usually saves money in the long run - even for the hobbyist, the cost of ruined PCB laminates can soon mount up! With the methods described, you can produce repeatably good single and double-sided PCBs for through-hole and surface mount designs with track densities of 40-50 tracks per inch and 0.5mm SMD pitches. Artwork generation When defining pad and line shapes, the following minimum sizes are recommended for reliable results: Media.

Do I really need a transistor to drive my solid state relay? - Hardware. Mdesmarais, on Feb 20 2010, 07:14 AM, said: morglum, on Feb 20 2010, 01:36 AM, said: Just to make sure, just replacing the LED with my relay and the 330 ohm resistor with a 1000 ohm resistor doesnt sound like a really bad idea, correct?
Also, quick newbie question if you don't mind. What's a good way to connect my DS2413? There's no way I could just solder wire to those small legs.... should I get a PCB? 1st question- You can calculate the current- I=E/R. . . so if you are using 5V, current would be 5/1000 = 5mA. BLH, on Feb 20 2010, 07:39 AM, said: I looked at the DS2413 specifications sheet and it is only available in surface mount. Thanks guy for your help. 1) For the resistor/amp calculation, I think I understand. 2) Re: the DS2413.

Voltage Sensor Module -Arduino Compatible - emartee.com. Arduino Voltage Sensor Module Description : This module is based on resistance points pressure principle, and it can make the input voltage of red terminal reduce 5 times of original voltage.
The max Arduino analog input voltage is 5 V, so the input voltage of this module should be not more than 5 V x 5 = 25 V ( if for 3.3 V system, the input voltage should be not more than 3.3 V x 5 = 16.5 V ). Because the Arduino AVR chip have 10 bit AD, so this module simulation resolution is 0.00489 V (5 V / 1023), and the input voltage of this module should be more than 0.00489 V x 5 = 0.02445 V.
