I found the AD5171 Digital Potentiometer project: https://www.arduino.cc/en/Tutorial/DigitalPotentiometer
I ordered the parts necessary for incorporating this application for periodic error control in my star tracking device for long exposure tracked star photography (the programmable pot will regulate motor speed in a repetitive pattern).
But now my problem: I can only find the AD5171 in SOT-23-8 casing. That means it is infinitesimal small by my standard, approx 3x3 mm, with 8 legs to solder...
It does not at all look like on the image in the above linked project: https://www.arduino.cc/en/uploads/Tutorial/AD5171_bb.png - It is a lot, lot smaller.
Is there an AD5171BRJZ10-R7 in a bigger casing, suitable for a breadboard, to find somewhere?
If not, I have found this adapter: http://www.proto-advantage.com/store/product_info.php?products_id=2200100
Still the 8 microscopic legs has to be soldered on to this little board.
- Is this possible with a soldering iron and normal soldering skills?
Advice on soldering technic (I have googled some, but found no video with someone actually soldering an IC this small)?
Any better solution to my problem?
