                    In honor of...     With the coming of Nanorama I think it is fitting to look back at another Arduino project 14 in Open Arduino . Back then we had the opportunity to work with the MKR1010. It amazes me how far hardware has progressed. Unfortunately as often is the case, the software lags behind. The ideas are there, but realizing them is very difficult because not en ...

And the Beat Goes on...

Posted by clem57 Top Member Jan 16, 2020
     So this little ditty was popular by Cher many years ago. But I just heard it on a commercial today. It got me to thinking how technology changes especially in storage. I just happened to look at a box in the corner of a closet. I decided to dig in and found this:               You see it is a Jump Drive from Lexar circa January 16, 2004 (based on when listed in Amazon). It has  whopping 128 MB. Probably big ...
  For anyone out here, I am wondering if this guy is for real? Is his statements based on true electrical fact or just a lot of fiction? Please comment below. Thanks for checking this out. Clem ...

New feature in Python 3.8

Posted by clem57 Top Member Nov 12, 2019
     Even though Python 3.8 is not official releases, there have been a few Alpha versions floating around. There are some interesting ideas in these including one called a Walrus Operator. Here is the explanation:   Walrus-operator is another name for assignment expressions. According to the official documentation, it is a way to assign to variables within an expression using the notation NAME := expr. The Assignment expressions allow a value to be assigned to a variab ...
     Sometimes it is good to look back to the past to see how far we have come in today's technology. With the announcement of the NXP RT 1010 which is a Cortex M7 running at 500 MHz recently, things have moved in leaps and bounds. In the 1960's, the latest technology of the day was found in the NASA program for Apollo 11. The first use of Integrated Circuits was in the Apollo Guidance Computer (AGC) the size of one cubic foot. Read this in Wikipedia for the details. It was c ...

Update: Raspberry Pi 4

Posted by clem57 Top Member Oct 21, 2019
     Good news for those who may want to boot from other than SD card. There is a new change out for doing just that. Y'all might want to check out this article in the Raspberry Pi documentation. Allows your boot EEPROM to be updated changing your RPI 4B to boot, say, from the network! Or a USB device when such code becomes available. Here is abridged details. Raspberry Pi 4 boot EEPROM The Raspberry Pi 4 has an SPI-attached EEPROM (4MBits/512KB), which contains code to boo ...
