During elementary and high school I was quite into model rocketry, building and launching a number of model rockets. Most of them were bulit around commercially available rocket motors. At that time some of my colleagues were building their own …

Today I spent quite some time figuring out how to set up a batch script to run before a bulid in a CooCox IDE. The script I wrote was to automatically change the bulid number of a program I am …

I did write a post on powering and using ESP114A power supply some time ago. To make the power supplies even more useful you can also convert one of them to a floating ground power supply. Floating ground power supplies …
So recently I wanted to generate two fast (40kHz), phase offset signals with Arduino. I have done various modes of PWM and PPM modulation before, but have not yet tried to generate phase offset signals. Actually there is only one …

I recently had to programm a NEO-6 GPS receiver module for a friend of mine, that needed it to have a specific baudrate and specific NMEA sentences to be sent. The module was to be connected to a ham radio …

I just recently obtained a safety copy of my old blog site. š when you want to keep your site alive you should really keep a safety copy somewhere. The legacy Rei-Labs.Net blog was actually my second blog, after the …
There are many integrated circuit products available for the USB to serial (TTL or RS232) conversion on the market. Serial communication protocols like RS232, RS485, RS422, USART, UART, LIN are still commonly used in industrial and commercial applications where only …
So today I figured I could update firmware on my ESP8266 to make it useful for work with the arduino uno. The problem with the original firmware is that the serial port baudrate is fixed at 115200 which is way …
I recently did a presentatiton on Low-power Piezoelectric Micropump Driving Module at the MIDEM International ConferenceĀ on Microelectronics, Devices and Materials. The module was developed at the Laboratory of Microsensor Structures and Electronics. Despite its small size the module is …
There is also an older post on this thematic in my blog, which describes the problem, but not so much the fix. Ok, this is basically very similiar to the Prolific driver fix. It makes the system think that the …
