2 LushOne Echosynthmodule– buildinstructions
Gettingstarted
•IfyoucanbuildtheLushOne basemodulethenthen
buildingtheEchoshouldbeeasy
•Remember:
–Accuracyandneatnessismoreimportantthanspeed
•Getitworkingfirsttime
–TheseinstructionswillguideyoubutIassumeyouare
familiarwithbasictechniquesandequipment
•Allcomponentsexceptthepower‐inaremountedon
thecircuitboard–noslow,fiddlypointtopointwiring!

Buildorder
Buildinanyorderyoulike,butIsuggest:
•Patchsockets
•ICs
•Resistors,capacitors
•Transistor,diodes
•Powerleads
•Internal/Externalfeedbackswitch
•Variableresistors

Back
Thefollowingcomponentsaremountedfromtheback:
•Everythingnotonthefront!

Patchsockets
•9smallsilverpatchsocketsfitfrom
frontofboard
•Fitinthelarge,labelledcircles
–Notthefourmountingholesinthe
extremecorners
•Solderroundrimonback
•Suggestyoufitfirstsoyoucan
makethemsitnicelyflushwiththe
board

ICs
•AllICsaremountedfromtheback
•ICsareprovidedunsocketed
–Youcanaddsocketsifyoulike!
•Positionsandorientationsaremarkedonthesilk‐screen
–Pin1alsohasasquarepad
•Thevoltageregulatorhasthesamecaseasthetransistors–checkthe
labels!

Transistors,diodes
•AllTransistorsanddiodesaremounted
fromtheback.
•Transistorsaremarkedshowingthe
packageorientation.Checkyouhavethe
transistorsandnotthevoltageregulator!
•TherearebothNPNandPNPtransistors–
checkyouhavetherightone
•Diodesareallverticallymountedand
shownwiththesquaresymbol.
–Thediode’sstripeshouldbetowardsthe

Checkingtime
•Congratulations– buildingshouldnow
becomplete!
–Takeabreak
•Timetocheck:
–Nopartsleft‐over
–Allparts(particularlyICs)intherightway
–Nobadsolderjointsorunsolderedjoints
–Powerconnectorsoncorrectly(very
important!)
–Nosolderbridgesorotherproblems
•Goodluck
