These days I have been trying my luck with surface mount components and wanted to give it a try building some boards. Also by playing around with the ESP8266. A while back I built a interface board to use the module with the Arduino, so now I wanted to make an independent board for the module. It has been done over and over on the web. Yes I know, but I haven't done it. I just put together a few components to give it a try. It consists of a usb to uart chip (CH340T) and an ESP8266 03 module. I b ...
Currently I am playing with the ESP8266 WIFI module as many others are. Since I want to create some Arduino libraries for it, I am in the need to do some debugging. The Arduino only has one hardware UART. And if you wire anything to the atmega UART port you may run into problems when downloading new code to the Arduino. The Arduino programs the atmega via the hardware UART port and if something is connected it may cause trouble. For downloading you end up disconnecting and reconnecting the ESP m ...
A few days ago I posted my fail with the ESP8266 model ESP-03. I never got it working (as of now), so I moved to the ESP-01 model. It worked like a champ. I upgraded the firmware on the module as recommended on the web and connected to my wifi network without problems what so ever. At first I didn't pull up the rest pin and it kept rebooting, but after pulling reset up it worked consistently good. Left it overnight connected and it was responding to ping on the morning, I am pretty happy. Like ...
A little more than a month ago a friend told me about a cheap wifi module. So I searched for this piece of wifi magic and founded the ESP8266 Wifi module. And it is really cheap. Depending on where you get it and the version we can say is between $5 and $8 for one module. Told myself I can spare $8 for this Wifi promise land so I ordered two for a little more than $8. Yesterday I got them, right away I got very exited!! On yes, new toy! First I realized that I ordered the ESP8266 ESP-03 model. S ...
The skull was working great connected usb to the PC. But I wanted it to be wireless. Since I have an Adafruit CC3000 breakout board available, decided to stick it in. Also a few years ago I made my own Arduino compatible board, based on the usbasp project and got the inspiration from the metaboard. My board end up beein a 5cm x 5cm board with Atmega328p which can run Arduino code.   The overview of the Internet of Skull now is like this.   With this architecture the laptop is just a ...
This is just an informal post to share with the community a sort of a new project. Really is more like an improvement or extension of an old project. As part of the Smarter Life Challenge my project was the GeoCar. I like the idea of adding smarts to the car. So now the car will have a little more brains. Brains in the form of a raspberry pi (what else?). Having more power packed into the project it is a nerd job to do as much as he can with the power given. Kind of a challenge was given to me ...
