So, it has been some time since I posted. I have a big update coming. I have finally started work on my talking pumpkin project. Soon I am expect to receive the last few pieces and that will let me start the final build. Overview: The pumpkin project is something I dreamed up this time last year having seen the thousand's of other pumpkin projects I thought why not build my own. What I have is a PIR sensor (more on that choice later) an uno and a pi. When the PIR gets tripped the uno sends a signal to the pi and a playback of a script is started. When the playback is over the pi tells the uno to start watching the PIR again. Yep, that's right, it's another talkingnpumpkin project. The How: So I ended up using a pi for audio and for managing the playback of the conversations. One of the "exciting" pieces of this project was getting the pi and uno to talk via serial over USB. Getting them talking was simple enough. Realizing that python does not like serial readline
I have been working on a new wifi enabled version of the pumpkin project and as part of that effort I am using ESP8266 modules. The issue I was having is that programming them via breadboard was kinda bulky and when I ordered a PCB for a programmer it turned out to have an error in the design. The solution was to create my own. I wanted something that was minimal in parts and would just get the job done. The final product is a simple PCB with 4 components attached. To program you hold down the program button and tap the reset button and BAM! it is ready to be programmed. I left out a 3.3v regulator like lots of the other designs out there since I always use FTDI friends that have a 3.3v setting. it has made programming way simpler. I hope you find it as helpful as I did also ordering it via OSH Park 3 boards only cost $3.10. For the build you will need: 1 - PCB from OSH Park - https://oshpark.com/shared_projects/XPf6uyN1 1 - 6 pin right angle header for FTDI - 609-3313-ND 1 - 2x4 pin
