This one is generally nothing new. I think I get quite a lot of things done. Am I always motivated? No. Discipline is the other factor and there are - I think - three aspects of it that help: Imagining the results. This itself kicks in the right chemistry (literally) - dopamine - the needed neurotransmitter. Dopamine is sometimes confused with endorphins and incorrectly considered the satisfaction molecule. People thought dopamine shot up because you got something good (like winning a game). But dopamine actually spikes before you get the prize. It is the fuel for motivation: it drives the internal incentive processing. It creates the craving, the focus, and the energy required to go get the thing. Making lists. Richard Branson's favorite: " I have always lived my life by making lists ". I too make lists all the time. To help my aging memory and remember important things in the exploding galaxy of interests and distractions. I don't use paper lists but several electro...

Bikerafting in the Abel Tasman National Park is now on my bucket list. Still very uncertain at this point as I first need to find a company - this activity is not easy alone. But first things first, I've placed it on the bucket list. And started sone preparations. If not Abel Tasman, there are many options elsewhere.  I had a mountain bike some 25 years ago but never went on a multi-day offroad trip. That bike is now barely functional and bikes in general have changed a lot. They are now much more capable to ride (hydraulic disc brakes do make a difference) and comfortable (the modern shifters reduced the complexity - just the rear shifter does it all with 11-12 gear cassettes).  I started building the bike with the help of AI (Gemini) as initially I even did not know what to ask for. It guided me with selection of frame and drive options as well as recommended a great local shop that beautifully put it all together ( Peak Bike in Krakow - highly recommended). And then I've ...

The Wallet app is one of the reasons I use my phone more often. For touch payments: when done by phone they don't require a PIN code: faster and more secure. For other card types: mostly as an organizer to have them all in one place. And then for airline boarding passes: not only for convenience, but more importantly as a backup. Airlines love their branded apps. Some of them are barely usable, just being mostly web views on responsive web pages with (almost) no offline functionality. Some are really good - like the often mentioned United Airlines app. But it turns out even the best ones can fail unexpectedly. Just last week my United app lost all my flights . Fortunately this was just the app. It was a bit scary moment, but of course GMail is the mother of all backups. So I retrieved the booking confirmation code of my upcoming trip, then manually added the flight to the app and was able to check-in. The check-in went fine and I added the boarding passes to the Apple Wallet. That ...

Automating customer support has ben the thing for the last 15 years. Or may be more. And has always been super annoying. But it seems recently the bots - mostly thanks to LLMs an much better backend integrations - have actually been quite good. Not all of them of course, but there are some good examples. Revolut is - at least in my experience - leading the pack. I don't have too many issues with Revolut in general, but when I do, the only way to star resolving them is through the "Help" option in the App. And actually with my most recent issues - all of them have been resolved by the automated bot. It is quite good on the front end - in the chat you can seamlessly add attachments and paste screenshots, which simplifies the process. It interprets images quite well. To the point that in many cases it is not even necessary to explain what the problem is - it gets it. But then it has also very good backend integrations. It can analyze the transaction history etc., and also ma...

Let's take a break from the heavy DALI issues series for a while. I did a lot of travel in the past 2 weeks (and a half). First it was LEDucation - the best lighting trade show in New York, followed by factory visits in China and the Bluetooth Asia event in Shenzhen. Was about to return home but then chasing an important business development I ended up detouring home through Australia. As always tons of lessons and experiences. I love being close to customers, as this really helps get down to Earth and understand their contexts, motivations, and - most importantly - what we should be doing to address them well. Also being a global traveler  has increasingly made me sometimes too confident. Take China - once you travel there once or twice, it becomes really easy to navigate there. And as everything is so overwatched (cameras everywhere!) and therefore safe, your vigilance drops. And this was the case when I ended up in Shenzhen / Shekou ferry terminal. This ferry is BTW super conve...

In episode one of the series I discussed the polarity of the DALI bus. Episode two was about application controllers. And episode three about what DALI-2 really is. This fourth episode of DALI misconceptions is about energy data. DALI drivers can report energy data. This is covered by the Part 252 specification. Most people refer to this as measured energy. DALI is digital, so must be precise. A driver reports the energy consumption so it must measure it, right? Wrong! Firstly, DALI Part 252 only defines the protocol and the data points. it does not say anything about accuracy of the data. This depends on the manufacturer, and some of them specify how accurate the reported values can be and some don't say anything. DALI Part 252 is definitely not a utility-grade data. It can be good for general estimates and definitely having the values available directly from the driver is a nice thing. But just because it is digital, you cannot assume anything about how accurate the values are...

In previous DALI myth busting episodes I covered the DALI bus polarity and DALI application controllers. This time we are going to the heart of it all: what is DALI-2 (and what it is not). This, on one hand, is the easiest one. On the other hand it is very rarely that people really know and understand what the DALI-2 logo means. There are many myths (and unfortunately many being repeated by AI assistants). Like : DALI-2 delivers device power over the DALI bus. Or control devices (see the previous post for details) are only standardized by DALI-2. This is all not accurate. As a matter of fact we could say there is no such thing as DALI-2. At least not a DALI-2 specification. Because a DALI-2 logo on a product means just one thing: the product passed DALI tests and has been certified. Practically this means the DALI organization made the best effort to ensure this product follows the specification and will interoperate nicely with other products that carry DALI-2 logo. DALI-2 does not s...
