Peek-A-Boo!

Posted by dougw Top Member Mar 12, 2020
Two element14 T-shirts in two days - Wow. This one came with a very useful breadboard. ... But not the cat - he just wanted to try it on. Hey - when are you going to learn to get the size right?   Thanks element14 ...

The Cat and the T

Posted by dougw Top Member Mar 10, 2020
The T-shirt is great - the cat has spoken... Note the nice element14 Presents battery it came with. What do you mean photobomb? .... this is my half of the shirt..... I was here first. Okay, lets see how to turn this into a game....   Thanks element14! ...
Somewhere in the last 2 years I lost the plot. I thought I would share my experience in case it benefits other members. One of my goals in the past 2 years has been to get nominated for member of the year, but I have not been able to figure out what it takes. The first metric I thought was important was participation. I addressed this by reading virtually everything that was published on the forum and commenting whenever I could contribute something useful. It definitely takes a lot of time to ...
Every year I review my projects for the last year, but when I look at the oddball list of projects I did last year, it really begs questions like "What was he thinking?" or "What was he into?" or "What was he up to?" It started with a magnetic levitation project to bring in the new year. Next it switched to a LoRa GPS locator project - part of the arduino MKR "Build a Smarter World" contest. Then it moved on to an R2D2 design and build - part of the "A Question of Scale Project14 contest". ...
In the past year or so I set out to explore what we members could do to improve interest and participation in the forum. This blog is a discussion of some of those initiatives. In total these activities took quite a bit of thought and effort so I wanted to evaluate them as a whole collection to determine if they were worthwhile or making a difference. I'll start with a poll that investigated road test fears: https://www.element14.com/community/polls/2629#comment-137994 This poll indicated ...

element14 T-Shirts

Posted by dougw Top Member Dec 18, 2018
It came up recently that it is possible to collect a whole week of T-shirts from element14. Here is the proof:   This collection is actually missing at least five T-shirts I have squirreled away somewhere, but it does show it is possible to have a lot of element14 T-shirts. I couldn't tell you what each one was from, although the "Live Your Ideas" shirts were won in a T-shirt design contest at element14 - and only available at Embedded World. I wore the Tektronix shirt on a pilgrimage ...

Goodies ....

Posted by dougw Top Member Dec 17, 2018
This is what I won for participating in the Project14 Test Instrumentation contest: Some of it was chosen by element14 (tool kit, PocketBeagle and swag) I chose the Pi 3A+, displays, proto stripboards, & transistors.   Thank you element14 - this is all going to come in handy.   Here is a link to my entry blog: µBOSS ....

This is the latest blog in my annual summary series. This year I will try to include a few more statistics for those that are interested in that sort of thing. Those that follow the forum will know from my comments that I greatly enjoy reading and learning from all the great content posted here by staff and members and the discussions provide  a further enjoyable dimension to the activity. The participation stats indicate I participated in over 764 discussions this year - more than 2 per da ...
A few months ago I purchased a 2.5" 2 TB USB hard disk drive mostly for backup, but I started using it for project work that had lots of video in it. A few days ago it wouldn't power up with my computer - it just made an intermittent beeping sound. After some research I decided this was probably a situation where the heads got stuck to the disk. I haven't seen any complete analysis of why or how heads get stuck to disks, but here is my speculation: Heads normally stay in their parked position be ...
Every year about this time I do a review of my forum activity over the past year. This summary provides some insight into the amount of time I expend on element14 activities and it also provides insight into how well the forum motivates me to participate. (pretty well ) So far this year: created 57 blogs - more than 1 per week created 83 videos - about 1 every 4 days spawned 10 discussions generated 6 polls applied for 7 road tests - successful on 6 made 3 design challenge proposals - 2 w ...
This blog is to add to theheckwithkaren blog about using Dollar Store parts in projects. I scour the Dollar Store for parts on many projects and I have use parts from the Dollar Store countless times. Here are a few examples: The Acrylic dome on my Konker Connection is part of a butter dish from the Dollar Store (The other part will likely be used to cover a solar panel on a different project): This urethane orb was found in a Dollar Store. It was used in my LED road test.   This PLA d ...

Phantom 4 Unboxing

Posted by dougw Top Member Sep 13, 2017
This blog will cover my experience with the DJI Phantom 4 which was a prize for my entry in the Safe and Sound Design Challenge. The objective is to provide those who were curious about the great prize in this challenge with information about what it was and what I'm doing with it. Initially this blog will cover the unboxing, but I will add to it when I have some video of the system in action.       This is a very high quality quad-copter with outstanding features and perfor ...

Makers - The Missing Link

Posted by dougw Top Member Jan 15, 2017
It is clear from the response to the "bit by the bug" blog that there are a lot of inspiring stories about how people became interested in technology. Active members of the forum can all relate to many of the sentiments and motives expressed. We can all make a long list of reasons why people get involved and like maker/hobby electronics. But why are makers different from non-makers? What is missing are big explanations about why more technical people don't get involved in maker/hobby electroni ...

CES 2017

Posted by dougw Top Member Jan 11, 2017
I finally made it to CES for the first time, which explains why I have not been active on this forum for a week. This is a beast of a trade show. CES showcases about 3,600 exhibitors in about 2.5 million square feet for over 170,000 attendees. Exhibit hours are from 9:00AM to 6:00PM (34 hours over 4 days). This only allows about 34 seconds per exhibitor if you want to see them all. Even if you don’t want to see every exhibit, you still need to walk at least 50 km to walk past each exhibit ...

Creating a Maker Wish List

Posted by dougw Top Member Dec 19, 2016
For me accumulating a complete set of tools, software, instrumentation and stock to permit building electronics projects has been a long slow process (decades) and it is still going on. This list is my idea of the most effective order in which to acquire new equipment. It takes into account cost and usefulness. I did not exactly follow this path as costs were different when I started - back then a DVM was a very expensive device. 3.5 digit DVM (DVMs are the most used instruments and they are no ...
