Earlier this day I accidentally published my Weller Soldering Station WT Series roadtest rather than saving it, something picked up quickly by stevesmythe and colporteur, thank you. It was more of a set of notes and a framework that I was hanging the information into as I gathered it.   Rather than my unfinished roadtest report constantly being turned over on the latest content list (as I added material) I decided to delete that roadtest and start again. Anyway I thought I'd post formally ...

Remember Your PPE

Posted by 14rhb Top Member Feb 29, 2020
Just a reminder to us all not to get complacent regarding wearing Personnel Protective Equipment (PPE) to suit the task being undertaken, in this case I'm talking eye protection.   Whilst using my 'Dremel' to de-rust a tool I assumed the bits flicking into my face were just rust however when I finally stopped I realised they were also brass wires: Luckily I was wearing my safety googles so my eyes were still OK. On a more serious episode I had a similar thing with a wire cup-brush in an ...
During the Holiday Special 19 and my Happy New Year Element14: my last project for 2019 project I ran into issues with the WS2812 LED's flickering and that issue was compounded for me by my use of the Arduino IDE and the lack of debug support. I also suspected that the Neopixel driver library may have been causing issues and so I carried on to port my code from the Arduino to the Microchip PIC range. I had previously managed with great success to use the Configurable Logic Cells (CLC) of a PIC16 ...

I had an email on my phone that UPS was delivering me a parcel. Having not ordered anything I was intrigued to see what it was. Upon picking it up I immediately recognised the parcel as an Element14 one . Upon getting home I eagerly opened it up to find a whole box full of fun as shown below: There's an Arduino MKR breakout board, a Molex antenna sample kit brim-full of antennas for every conceivable use, a T-shirt, stickers (some of which which will adorn my 3D printer), a USB power bank (v ...

The Trickle Charger

Posted by 14rhb Top Member Oct 13, 2019
1.     Introduction For years always wanted to build something that harvests energy but I could never quite manage to actually start the projects off. I like the idea of recycling waste heat in air conditioning or waste water to extract old heat energy but have never had the confidence to re-plumb the house. I did once make a very large and heavy aluminium plate heat exchanger that could pull the energy from waste heat exhausted from a house (e.g. the bathroom) and would warm ...

Just a quick update that might help other BB-AI experimenters. I managed to get the TIDL software to identify the cat example iBox: #2 Setting up the BB-AI so I decided to try and identify a moth: I pulled it into the BB_AI using wget command and placed it in the same place where the cat jpeg file was located. Although TIDL imagenet ran on this file it wasn't able to read it, although the test was finished with a PASSED, which was a bit strange. I tried renaming my file from Moth1,jpg to M ...
