1) No one is allowed to sell more than one unit per order for Zero W per Raspberry Pi rules (boo!) and 2) The Zero WH has the header pre-soldered, which will make our project assembly super quick and easy. We are using the $14 Zero WH instead of the $10 Zero W for two reasons. As of the time of this writeup, it is hard to find a vendor that allows more than one Zero WH per order except for several UK vendors that have either no limit or a limit of 10. You can easily get each item above in bulk to minimize shipping costs with the exception of the Raspberry Pi Zero WH, which may be more challenging outside of the UK. The setup for each sensor node is going to cost ~$31 plus shipping (~$37+shipping with the case). (Optional) Raspberry Pi Zero W case ($6).DHT22 Temperature/Humidity Sensor ($5, two-pack for $10 here).Here is the list of everything we need per sensor node and the approximate cost (minus shipping): Step 4 - Grab foot_top, foot_bottom and foot_ground (and foot_top) and assemble them.Raspberry Pi temperature sensor network video tutorial The HardwareĪ perfect application for a $14 Raspberry Pi Zero WH is to Network Temperature Sensors as this device is compact, inexpensive, powerful, and has built-in WiFi.Then attach joint_top and joint_bottom altogether Step 3 - First put 2 x MG92B, leg_top and leg_bottom together with M2x30mm screw and nut.Step 2 - Grab one joint_cross, joint_top and joint_bottom and combine them.Step 1 - Combine thigh_top, MG92B and thigh_bottom, use M2x30mm screw and nut to secure them together.Modification is required if you want to use alternative servos. The dimension of 3d printed part is highly dependent on the servo's size. Use the buttons on the panel to control the hexapod.Connect to the hexapod using the IP address.Find the correct IP address of the Raspberry Pi on the hexapod.The compiled program can be downloaded under the release page. PC program source files are located under.
