ISO bicycle turn signal SYSTEM - wireless controller, pairable with multiple signal lights/colors/

I love bicycles: in my younger days, road bikes, then touring and cargo bikes, now an e-bike

My rides always involve busy roads that have no shoulders, steep hills (coasting speeds > 30mph) , crossing traffic lanes, often only 1 lane in each direction,  and no protected crossings where I need them.  I feel that I need a rearview mirror and turning signals.  This post is mainly about turning signals, although 

While it would be great if the turn signals could connect to the eBike batteries. That's not a requirement. Lights with batteries, or, better, USB rechargeable, would be fine.   

Wireless turn signal controls are all over the web, including Amazon. As far as I can tell, the wireless bicycle turn signals that I have found via Google and Amazon have one controller, and one or two signals.  There is no ability to pair extra signal lights to the same controller.

 

It seems to me that it should be possible to have a SYSTEM of wireless turn signals for a bicycle.  

A wireless turn control mounted on the handlebars or nearby.

Multiple sets of lights - not just 1 or 2, but

Multiple sets attached at different places on the frame.   

• E.g. on the rear so that not hidden when I am carrying a full load of cargo; 
• on the seatpost; 
• on the handlebar ends; 
• possibly integrated in rearview mirrors mounted on handlebar ends
• Less common
• ?pedals?
• ?front facing turn signals?
• sideways -- e.g. wheel lights.

Different colors: amber, red, etc.

Different turn indications: flashing, arrows...  Heck, I would like an "I am slowing down indicator" when I am descending a steep narrow road at speed, with a car right behind me.

Different attachment styles.  E.g. rings suitable for seatposts and handlebars; handle ends; velcro straps for my e-bike, which doesn't have the thicker posts where such lights would need to be.

As with any such battery driven lights, redundancy - two lights, either side, either direction - would be best, for the case where one battery runs out.  Quick release to make it easy to charge them at home or office, plus to protect against the theft of the accessory light, as when parked at grocery store.

If only we could donate platelets every 6 days rather than every 7 days

During COVID I have been trying to donate platelets every  week.   The Red Cross  requires  at least 7 days between donations.

It is a pity that this minimum spacing cannot be every 6 days. I can really only donate on weekends,  Saturday and Sunday.  But if I donate on Sunday  one weekend I cannot donate on Saturday the next week -  too close.   The only way I can  switch back to donating on Saturdays  is to miss a week. 

Does it really make that much of a difference?

--

Imagine that  on even weeks I can donate on Saturday but on odd weeks I can good donate on Sunday.   With the 7 day rule  the number of donations I can make is reduced by 33%,  compared to being able to donate every week  as would be allowed if the  separation were 6 days.  That's more than the 1/7th  you might  naïvely expect.

Such phenomena of quantization are common in computers. E.g. on P6 our  4 cycle FP multiplier and 3 cycle FP adder shared a pipeline.  If we had not stretched the latency of the adder  to 5 cycles we would have lost a lot  of compute bandwidth.

Wearable: suggest products: (1) media remote ring, (2) touch to XXX ring

 I just sent the following to Amerteer, from whom I bought a "wireless(BT) Presentation clicker ring"

Amerteer's website  not spelled the same way: http://amteer.com/Empty-contact_us.html

Because I like to see anybody do this .  Amerteer just came to mind because I've already bought 1 of their products.

I bought your  presentation clicker ring.   it shows promise, although the key bindings you have used are useless for my purpose.

May I suggest that you consider creating a "media remote ring"?  Like the Satechi Media Remote Ring?

Buttons  for each of these following standard PC key codes

Media_Play_Pause

Media_Next

Media_Prev

Volume_Up

Volume_Down

Noting that  this media remote has 5 buttons just like your presentation clicker, arranged in the same shape. The only differences that the key codes  sent to the PC are different -  and possibly the  symbols you print on the keys might be different.

I suggest the media remote ring because  it has a  big market comparable to your presentation clicker ring.  Which is more common?  PowerPoint presentations, or playing video? (Or both?)

I have other ideas for such ring devices.

E.g. I would like a push to XXX  button - a button that I can touch lightly.  When I touch, it emits a keycode like Media_Play_Pause DOWN.  When the touch is removed, it emits the keycode Media_Play_Pause DOWN

I.e. separate control for touch/down and release/up.

I am able to do this with the Satechi media remote ring,  and other media remotes.   however, the membrane buttons they are using require too much force me to keep press down, so using them for press to talk or  press to play  is uncomfortable.   therefore I'd like to suggest that you  use either a lighter touch button, or possibly a capacitive sensor  that can just tell when the fingers touching.

 I would prefer  key up/down push to touch  to auto repeat.   I don't know how widespread my need is, although I think it's more common now that touch phones are very common.

BTW:  my application: I use a dictation device  with speech recognition software. I would like to  "press to talk"  when I am dictating/talking to my computer. Faster than having to click a mouse button or the like, since I'm operating totally hands-free.

 I am currently using the Satechi media remote key,  but like I said the button requires too much force and is uncomfortable for push to talk.

Like I said, I have other  ideas for rings/finger worn devices.   as I am sure you  know,  there are many fancy proposals like gesture control and NFC and  Biometrics so on.   Those are great -  but your  presentation clicker and/or a media remote ring  are much simpler, and can be done with what you currently have. Just a slight reprogramming of your existing device.

 In fact, I don't even need all 5  buttons on your current presentation clicker ring device.   I would actually prefer to have only a single button. smaller, etc.

Trackball scroll ring causes "computeritis" ?! :-(

I have long used a trackball rather than a mouse.  It greatly helped my "computeritis" - sore hand/wrist/arm.

One of the first trackballs I used, and my longtime favorite, was the Kensington TurboBall.  4 buttons and a scroll wheel - which IIRC could also be clicked as a 5th button. But it was discontinued by Kensington, probably because it was a mechanical trackball, and had reliability problems.  After many years all six (6!) of these that I had purchased failed. I have not had good luck with the used TurboBalls that can still be purchased on Amazon.

I am currently using the  Kensington Expert Mouse. 4 buttons, and a scroll ring, non-clickable. Actually 2, one on either side of my keyboard. 2 more at work, 2 more at the coast, 2 more at my mother's house, and 1 in my suitcase for trips.

I guess that you can say I have liked the Expert Mouse well enough to buy 9 of them.  Serious $$$s.

But: I dislike its incline - I am currently shopping for a mouse tray to give it a negative incline.  Or at least foam blocks. But at least that is hackable, although even a non-tilting mouse tray costs more $$$s.  I have even tried using the trackball upside down, to get the negative incline I want. Works okay, but the USN cable gets in the way.

Worse: I have come to realize that the ExpertMouse scroll ring is bad for my "computeritis".  Scrolling a ring is a much more complicated movement than scrolling a wheel.  It uses many more small muscles.  And my hand/wrist gets sore.

I wish I had my old scroll wheel.

I have been worked on AutoHotKey scripts to scroll using the actual trackball.  Works somewhat.  Most existing scripts require holding a key to scroll with trackball, which hurts; but it's easy enough to make a key press and release toggle the "scroll with trackball" mode.   Worse: in AutoHotKey scrolling with trackball seems to require a timer triggered polling function, wasting power.  Plus other issues as I mention in an AHK forums post: problems with displays that have different display scaling, cursor flickering, etc.

I am considering buying a trackball that has a real scroll wheel.

Or  possibly one of the ITAC trackballs, that has a mode button converting it into scroll mode: the ITAC Evolution 149$ 6 buttons  or ITAC Professional 189$ 4 buttons. The former's 6 buttons can all be configured. No driver SW required. OS independent.  But probably only scroll up/down - no scroll left/right, without more OS dependent AHK scripts.

BTW, more and more I prefer OS independent driverless devices.  Programmable once, then works everywhere else.  E.g. I might be able to program mirror images of the ITAC Evolution, so that my left and right thumbs always hit the same button.

I am seriously considering buying the ITAC Evolution,. But since I nearly always buy more than 1, this quickly becomes serious money.  Still, hand pain preventing me from working can cause serious loss of income.

OneNote LOG special page naming conventions

e.g. ** Tuesday, March 19, 2019

A "** Day LOG page".

Special page indicating start of a day.

NOT necessarily containing the actual log entry

Frequently empty, with OneNote pages for that day following.

Sometimes I add comments, etc., about the day.

The creation date for for a "**DayLogPage" is typically set to 12:00AM midnight on that day,
in the timezone I was working in at the time.


Mostly NOT using OneNote sub-page indentation

I would like to use OneNotes parent / sub-page relationships - but OneNote only supports 3 levels (top,sub,subsub), which is nowhere near enough.

E.g. I might like to have collapsible Week/Day/Topic/sub-Topic) hierarchy


. Spacer Pages

I find it convenient to have spacer pages in the list of pages within a OneNote section.

Since empty pages get "Untitled page" implicitly supplied, instead a use pages whose title is as close to invisible as possible, just a "." (period).



---+ section special pages

I use these to divide the pages for a day into sections.
---+, ---++

Default sections are for sorting - taking Raw LOG pages, and dividing them into work and non-work related pages, so that I can separate work and non-work

---+ Work - Restricted

Stuff that is work restricted, sensitive, or proprietary - stuff that should be moved to a company notebook, stuff that I am not

Sometimes I may leave a link to such work restricted stuff around in my personal notebook LOG.

Sometimes even the title of the page is restricted.

---+ Work - Related - Public or Personal

Stuff that is work related, but which is not company proprietary, or secret.  Stuff that may be left in my personal notebook - although I may move a link to my work notebook

E.g. HR stuff. 

E.g. public technical papers, that I think may be relevant to work projects.

---+ Personal or Public - not Work Related

Stuff that is not work related.  Stuff that need not be moved or linked to a company notebook.

Not distinguishing public, personal, private.  Assume personal or private.

---+ Not Yet Classified

Typically I insert a block of special pages

** Tuesday, March 19, 2019
---+ Work - Restricted
---+ Work - Related - Public or Personal
---+ Personal or Public - not Work Related
---+ Not Yet Classified

collect OneNote pages under the ---+ Not Yet Classified
special page "section",
and then during review move them to the appropriate classification,
and thence to the appropriate company proprietary or personal notebook,

DHMXDC Surface charger: fails new PC, works old PC

I wanted to post this review on amazon.ca, but was not eligible[*], so I am posting here:

DHMXDC Magnetic US Plug Power Supply AC Adapter Cord for Microsoft Surface Pro 3/PRO 4 Intel Tablet (Pro 3 Adapter Without Usb)(Taboe Charger)Sold by: DHMXDCCDN$ 20.00

 

I forgot to bring an airplane-ready[**] laptop charger on a recent trip, so I purchased this from amazon.ca on the plane while travelling to Canada.

This charger did NOT work with the Microsoft Surface 2-in-1 tablet PC I was using on the trip. When plugged in (a) the charger connector lights up, as if working, but (b) PC system icon reports "plugged in, not charging".    This seems to be as reported by about half of the reviews.

I initiated a return request with amazon.ca the same day. The vendor responded, but had not authorized the return before I had to leave Canada.

On my return home, I found the the DHMXDC charger worked with an older Surface.  I will therefore keep it - too much hassle to get the vendor to complete the return authorization - but I will be reluctant to work with this vendor again. 

---

Note *: Since I live in the USA I normally use amazon.com, where I post reviews, rather than the Canadian site, amazon.ca which will not allow me to post a review unless I have purchased 50$ in the last 12 months.  Amazon.com will not allow me to post a review for a product I purchased on amazon.ca

Note **: by "airplane ready charger" I mean a charger that will work with the power outlets on many airlines.  The surface dock that I was travelling with drew too much current, and caused the air line power outlet to shut off.

IT forced password changes => weaker password

Every time my company's IT forces me to change my password, my password becomes weaker.

At least, the password(s) that I actually have to enter by hand, manually.  

Frankly, I don't care about weakening the passwords for my company accounts.  After all, it's their IT department that is enforcing this obsolete policy.

But it is annoying that company IT also forces me to change my personal password on my personal machines that I use to log in to company email and VPN.   Those personal passwords start out really string, but get weaker every time IT forces me to change them.  So it's my personal security that is being messed up by company IT.
