Introduction: Diy Simple Solarbotic Solar BEAM
this is a simple project to build 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
Step 1: Solar Panels
the BPW34，each can provide 0.5V and 1.7ma
it have positive electrode.when you soldering it on the PCB,plz do not get it wrong
Step 2: Bpw34
7pcs of bpw34 is series connection
Step 3: The 2n3904 and 2n 3906
Step 4: Soldering the Cap 104 and CBB Cap
Step 5: Soldering the 1K Resistance
Step 6: The Ht7027 Socket
this is for installing the ht7027 trigger
Step 7: 100k
the 100k resistance is Pull up resistor for ht7027 out put
Step 8: The Trigger
Step 9: The Big Cap
the 4700uf Cap is for Storage electric energy,it need a diode to connect to the solar panels's "+"
Step 10: Assemble the "solarengine" and the ''solar Panels" Together
The relative angle between 2 circuit boards,depend what you like,i think BEAM is for Imagination and creation
so you have done the two PCB,the rest of the matter is make the robot what you like
Step 11: Where to Solder the Motor
there is a tag “motor” one the PCB,we can connect motors,leds and buzzers here
Step 12: All Done!
We have a be nice policy.
Please be positive and constructive.
