Stripboard Soldering
"Solder the Stripper" Workshop

Participants learned to solder three circuits onto a single stripboard:  an LED flasher, a code practice oscillator, and a crystal-controlled transmitter. 
Time: Saturday, November 22, 10 am - 1 pm PT

Congratulations to our Participants! Allen K6AGW, AnneMarie WD6AMA, Bob K6ZLY, David KO6FSG, Gert KK6ZGA, Hank K6HUH, James AE6JG, Kirk KO6HLW, Kishore KR6RAO, Mark AJ6FL, Tawny NØCALL

Tool suggestions: a controlled temperature 30-60W soldering iron or soldering station with replaceable tips (Yihua, Hakko and Weller are top quality brands carried by Amazon. Avoid the $5 Harbor Freight or Walmart irons); 60/40 rosin core tin-lead solder; needle nose pliers; diagonal cutters; and a 9 volt battery.  Bob Mix, KF6ABC, says, "Parts-Express.com has the Stahl STSSVT and Elexp.com has irons that may be decent.  Also solder."
