Since E14 is all about gamification, I thought it would be appropriate to share a fitbit Pole-to-Pole badge that I just got. And more appropriately to acknowledge what I think is an impressive design example - the fitbit One tracker. ...
Happy St. Patrick's Day to the Element14 Community! I was wondering if there was anything that I could do quickly with something that was green. The Pi Pico came to mind immediately, but serendipity won the day. When I arrived home afte...
I thought I shouldn't let Pi Day go by without doing something on an RPi, so I decided that since I've been using the C/C++ SDK with the RP2040 that it would be appropriate to try something on the Pi Pico with MicroPython and the Python SDK. I'...
Normally, I travel away from home 6-8 times a year. Almost exactly a year ago, I returned home from Hawaii on the same day that my mother's assisted living facility on Oahu went into lockdown due to the pandemic. I haven't travele...
I recently accidentally discovered a part of SparkFun that I hadn't encountered before - SparkX, their line of experimental products. I purchased a MicroMod Big Display Carrier Board https://www.sparkfun.com/products/17718 to try out b...
I'm not sure why it never occurred to me that you could do incremental flash loading using UF2 files. Seems relatively obvious since the file includes the load address, but I guess I've never had occasion to do it before. In my pre...
This falls in the category of buying and trying something just to see it work. I first got interested in microcontroller generated video displays back in the late 70s when I had a KIM-1 "single-board computer" which used a 6502 microprocessor (l...
I decided that for my Holiday Special 20 shopping cart that I would get myself an RPi 400 kit since it was in stock at Newark and cost an even $100 . A great belated Christmas present!Raspberry Pi - Pi400 - All in One Raspberry Pi, Keyboa...
I recently saw that Electronic Goldmine is selling new old stock of Signetics NE564N PLL ICs https://www.goldmine-elec-products.com/G25530 . This brought back memories of my early career in electronics working at the University of Hawaii from 19...
Last week I received a couple of boxes from Newark that turned out to be the Multicomp Toolkit bundle that I won in the Holiday Special 20 competition - Thanks Tariq and Element14 ! One of the tools included was a USB oscilloscope MP720016-US&nb...
I want to start doing data collection "untethered", so I've been looking at how SensiML has implemented data capture over WiFi and BLE. In order to do data capture over WiFi, SensiML uses a ESP32 UART to HTTP bridge. Instructions for doing...
This is a continuation of my previous post Using SensiML with Arduino Nano 33 BLE Sense - Data Capture . In preparation to building a model in Analytics Studio, I needed to capture a larger dataset using Data Capture Lab. I am going to try...
This is a continuation of my previous post SensiML Toolkit for TinyML . I watched all of the 10 videos of the Quick Start Tutorial Series and while they were informative, I found them to be a bit disjointed because they did not follow a si...
While I've been recuperating from a back injury, I found an interesting tutorial series for SensiML on YouTube: Quick Start Tutorial Series .The 10 videos take about an hour total. A good binge watch with the dog . SensiML, a subsidiar...
This probably fits in the category of oversharing, but about a week ago I injured my back while helping my son work on drywall at his condo. As a result, I've been struggling to complete a few projects that I've been working on and it's obvious...
It's the start of a new year and the time that I normally do a lookback at how well my rooftop solar system has done over the past year. I installed the solar panels and inverter at the very end of 2017, so I now have 3 complete years of data.&n...
About a year and a half ago I got an Onion Oboo Smart Clock as part of a Kickstarter campaign. I had posted about how disappointed that I was that Onion had not been able to meet the goals that they had set out in their campaign.Oboo Smart Cloc...
I encountered a few problems trying to run DPU-PYNQ on the UltraZed-EV during my roadtest a couple of months ago. Actually, I've tried to run a few variants of UtraZed-EV hardware configuration with PYNQv2.5 with little success. The U...
In May of this year I backed a Kickstarter campaign for the TinkerGen MARK: Make A Robot Kit, your hands on AI learning experience TinkerGen is a spin-off from Seeed Studio that targets STEM education. This campaign is focused on bringing ...
Back in May Xilinx released DPU-PYNQ which is an upgrade that incorporates DPU overlays and Vitis-AI into PYNQv2.5. Currently the Ultra96(v1 and v2), ZCU104, and ZCU111 boards are supported and with a little work you should be able to upgrade ot...
Just a quick update. I found the problem . It was not an installation issue per se, but a model mismatch issue. A problem with pre-compiled model versions and OpenVINO versions. It is documented here: https://github.com/openvin...
I'm getting an Intel Movidius NCS 2 Neural Compute Stick next week and I want to try using it with my RPi4 2GB, so I'm going to need to install the OpenVINO toolkit, the Model Optimizer and the Open Models Zoo repository. I'm antici...
