ESP8266 DIY Programmer Cradle

If you have been reading my posts lately, you will notice that I have been working a lot with the ESP8266 wireless module. To make it easier to work with, I made an ESP8266 DIY Programmer Cradle. Here is what it looks like (without and with the ESP8266 plugged in):           …

MicroPython WebREPL on Android

I created an app (apk) to run MicroPython WebREPL on Android. Imagine you have your ESP8266 (with the MicroPython firmware) in some location where the only access to it is via a wireless connection. If you need to access and change/control it, you will need WebREPL. Of course, a wireless enabled laptop would get access …

ESP8266 MicroPython Firmware

To enhance the capabilities of the ESP8266 there are various firmware packages available. In my last post, I showed how to install NodeMcu which uses eLua. I am a big fan of the Python programming language, so I was very happy to see a Python version for the ESP8266. The ESP8266 MicroPython Firmware is available …

ESP8266 Custom Firmware

If you would like to go beyond the basic features in the ‘default’ ESP8266  firmware, it is possible (and relatively easy) to create your own ESP8266 custom firmware. With ESP8266 custom firmware, your possibilities for interaction with connected devices are almost endless. The reason why is that you can now connect pins on the ESP8266 …

Best Kept Secret

Yes, it is an ambiguous topic. No, I don’t think it should be hidden, however, the fact that this topic does not seem to garner much press could mean it has been a best kept secret. The “best kept secret” is the programming language Forth. For reference, take a look at “A  Beginner’s Guide to …

How to convert an STM32F103C8T6 into a Black Magic Probe

There are several tutorials on the internet showing how to convert an STM32F103C8T6 into a Black Magic Probe. Unfortunately, none of them worked for me. So, I decided to write this post in case others run into the same problem as I did. The problem I ran into was the memory size of the STM32F103C8T6 …

SSD1306 OLED Displays

For many Arduino projects, there is a need to display information graphically or display more text than what fits on a 16×2 LCD. For that need, consider using SSD1306 OLED Displays. SSD1306 refers to the controller or driver chip for the display. OLED or  Organic Light Emitting Diodes refers to the dot-matrix graphic display system. These …

ARM Cortex M3 STM32F103C8T6

It’s amazing what you can get in a microcontroller board these days for just over $2. For example, just search ebay.com or alibaba.com for the key word ‘STM32F103C8T6’.  You will see the links to an ARM Cortex M3 STM32F103C8T6 development board for just over $2 US including shipping (usually from China, so it may take …

Hacking your Car with an Arduino and a CAN BUS Module

Your car is full of electronic devices. In fact, General Motors is one of the largest computer manufacturers due to its need of microcomputers in cars that it makes.  If you have an interest in what goes on with your cars’ electronics, you might want to invest some time hacking your car with an Arduino …

PIC Assembler Coding

PICKit2 Clone Programmer

I became re-interested in Microchip PIC assembler coding recently. I hadn’t really used it for a number of years (since before 2009). The ‘C’ language is usually efficient enough and easier to code for most projects I do. I used one of my DIY PIC18F4550 Pinguinos for experimentation. As you might guess, I decided to …
