All of my journey with Arduino started when I wanted to control my fan & a light remotely using a wifi button. … I’m too lazy…
After quite a long search I found this particular article that describes how I can connect & send commands between two ESP8266 wifi chips. I completed my basic requirements using this article. I could turn on & off an led at the server end using a button attached to esp8266 at the client end. The link is below.
Now I wanted to implement this using SELF SUSTAINED suitable opensource hardware … After quite a deep search, I found out two DIY circuits which serves my purpose.
For the server, I found a very well documented PCB which as AC input & 2 relay outputs which can be controlled using an inbuilt ESP8266 chip on the same PCB. BOM for the components in the PCB was provided in an excel file with links directly to an online component store. The link is below.
For the remote (client), I found another DIY circuit. An OCTOCLICK designed by Moritz König which has 3 buttons that are controlled using ESP8266 wifi chip & programmed for controlling 3 different accessories using those buttons. Most importantly, it is so well SELF SUSTAINED, that it works just on a 110 mah battery & will run up to 6 months on a single charge. It was a superb design with lots of thought put into by Mr Mortiz. The PCB & other details of the circuit were released yesterday.
But to my bad luck, the BOM details include just the list of elements & the working of the circuit, but nothing much is given in details regarding which resistor / which capacitor in which position. Also since I am not from the electronics background, I cannot make out which component to choose from a huge list of components in the electronics component store online
My requirement… No no… . rather REQUEST… Please, someone, help me sort out the BOM to the components numbered in the circuit. Also, a link to any of the online component stores for each of the elements in the circuit.
This is the link to his project.
I am also attaching the circuit & also the elements in the BOM which I could sort out myself
LIR2450 & holder - Locally available.
I need to find the remaining items which suit the PCB & their assembly positions on the PCB.
Resistors 0603 (1M, 470k, 100k, 47k, 10k, 1k)
Capacitors 0603 (1µ)
Diodes 4148 SOD123
Buttons (3x white smd, 2x micro black)…
I already have been trying to get the info from the designer, but there was not much response. I have already ordered the PCBs & want to purchase the components by the time the PCBs arrive.
