this is a simple project about
building a solarbotic
we use 7pcs of bpw34 silicon photocell，each of them can provide about 0.53V voltage and 1.8mA current,that is very small，right？ so we use a Circuit called "solar engine",to Storage electric energy,and a Voltage trigger(HT7027A) to detect the Capacitive voltage ,when it reach 2.7V,the trigger will out put a “High level”,so it Trigger the entire circuit, start discharging,the Motor and led start working.Repeat this process
most steps are the same with this project
the only difference is the mechanical system,yes,and
More than a buzzer
this is step1(but not really step1,in fact,it maybe step10 for this project,i am too lazy too edit the
Welding element plz Reference resources https://www.instructables.com/id/Diy-Simple-Solarbo...
this step we assemble chassis
the 4 copper pillars use super glue to Stick to the correct position on the plastic board.becareful,dont Get the glue out of the place.
Gear combination(Don't be too tight！)
Step 2: The Capacitance
the 4700uf CAP use for Stored energy
the foot on left is"+",the right foot "-"
Use pliers to foot bent into shape like the picture
Step 3: Solar Panels
if you already read https://www.instructables.com/id/Diy-Simple-Solarbo...
and finish the Solar panels
now this step we put it on the "-" foot of the CAP(7 solar pannels Series connection,their "-" to the cap ‘-’ )
the diode connect the “+” of the CAP and the “+” of the solar panels In order to prevent backflow
