Shin pads are moldable

I have been searching for new shin pads for soccer for a while. Most that are on the shelves here are thick and and awkward. I finally got some anyway (Nike Mercurial Lite), but hated them because they were way too wide in the bottom.
Then someone mentioned that hers were intended to be heat molded. I figured the chances of mine being a thermoplastic were pretty good. So, I put them into a pot of boiling water for about a minute and pushed them into shape over a pair of socks. They molded quite easily. Wrapped a velcro strap around them while they cooled down, and they now seem to hold their shape nicely.
The finish that used to be shiny on the outside is now a bit wrinkly; this may actually be a good thing, maybe it will make them less slippery.
Will have to see if they last and keep their shape.

Using wikidata to link to an article about a disease on wikipedia by ICD-10 code coded as property on wikidata

Wikidata is a sister project to Wikipedia that encodes much of the information on Wikipedia into discrete data values that can be queried.

I needed to document some ICD10 diagnoses and wanted to add links to Wikipedia as part of that. I did not know the actual names of the articles on Wikipedia, though. Manually, I could have found them using a search, but that would be a lot of work for >1700 diagnoses.

Turns out that Resolver will do this.  The following link will resolve the ICD10 code (P4229) with value K37 (corresponding to appendicitis) to send me to the Wikipedia article for appendicitis:
https://tools.wmflabs.org/wikidata-todo/resolver.php?prop=P4229&value=K37&project=enwiki

You could use similar code to link to a city by postal code or an animal by its taxonomic name, or using any of the thousands of properties available on wikidata.

See here for an example on how to use this with semantic mediawiki.

Zapier

An organization I am involved with does its internal communication and broadcasts exclusively through Slack. In my mind, Slack is “evil” because it lets communication in but doesn’t seem to provide tools to let communication out. For example, they don’t provide RSS feeds. I do most of my daily surfing through RSS feeds.

Today I figured I should look into this further and posted the question on the Slack Reddit.  Someone suggested I could do this through Zapier. I had never heard about them: they provide integration between different web apps. Sure enough, 15 minutes of tinkering later I now have an RSS feed from that Slack channel.

Things should not be so complicated, but when they are, it is good to have a tool like that!

More remote switching on the backpack

I have had a remote switch for the light on my backpack for a long time (holding up well!). I thought it would be nice to add a remote switch to the garage door opener.

So, I opened the heat shrink up and solderedIMG_20160920_153503 another switch on the remaining two leads in the USB cable. Some more surgery on the other end to attach two connectors. Then open up the garage remote and add wires to each side of the IMG_20160920_152807momentary push button that opens the door. Taped a block over the original button so it doesn’t get pushed by other things pressing into it.

Connect, and open the garage door. Should have done this ages ago.

Two computers, one set of speakers

We have two windows computers in our kitchen. For a while now they have been set up so that you have to plug the one you sound in listen tabwant working right now into the external speakers. Today I finally looked into a better way. Turns out there is a free one, or free as long as you already have a male-to-male audio cable.
Plug one PC’s audio out into the second PC’s audio in. On the second PC (Windows 7), go into control panel, sound, recording, pick the plug you used, and click properties. Click the “listen” tab and check “listen to this device”. I had to set the levels way down to 5/100 to not get any distortion and just get a full volume output from the first PC.
No more plugging around!

Blackberry m4a audio files in Audacity software

I use use my Blackberry to record audio in meetings and such. It records as m4a.  I use Audacity to edit audio files.

Audacity doesn’t do M4A natively, and the error it gives just says that it can’t read the file.

Turns out they almost have it built in. I didn’t research the exact IP reason that forces them to do it, but the instructions how to finish setting up Audacity to be able to read your Blackberry sound recordings is here:

Link to Navigo to go to a specific destination

Winnipeg Transit’s Navigo generally won’t let you enter a destination unless you first enter a “from”. I wanted to be able to add a link to a web site that says “if  you want to come here, you can take the bus, click here”, like this link  which will open the Navigo page with Assentworks pre-populated as an address.

Asked 311/transit, and they explained:

The user needs to include the destination information in the link. The best way to do this is to plan a trip using the desired address as the destination, it can be any trip (random origin and time). From the results page, click ‘Modify Request’ in the sidebar. This takes you back to the trip planning page with pre-filled information. Copy the URL from this page, it will look something like:

http://winnipegtransit.com/en/navigo/submit_destination?authenticity_token=****************************&destinationKey=13&destinationName=Forks+Market+%281+Forks+Market+Road%29&destinationType=monument&method=post&originKey=3911&originName=MTS+Centre+%28300+Portage+Avenue%29&originType=monument&tripDate=0

Delete all the unwanted information from the URL (keep all parameters related to destination [destinationKey, destinationName, destinationType]). Then it will look like:

http://winnipegtransit.com/en/navigo/submit_destination?destinationKey=13&destinationName=Forks+Market+%281+Forks+Market+Road%29&destinationType=monument

Use this URL to link to Navigo.

 

backpack light with remote switch

I ride my bike to work on main roads year around, so I need to be visible. In the winter that means lights. If I attach them to the bike, I have to remember to take them off, and they are relatively low to the road and less visible. I had them on my helmet for a while, but that was heavy. So, I have them on my backpack.

This has worked well for some time, but I usually put on my backpack and then remember that I did not turn them on. Then I have to take the pack back off and switch them on. So, I added a remote switch to the EL driver where its

internal switch is attached. Because I wanted to still be able to disconnect the driver, I wanted a plug connection. All I had flying around was an old USB port and plenty of USB cables to salvage, so that’s what I did. Ya, I labelled it “NOT USB”.

I made the remote switch by wiring a scavenged

switch soldered right onto the cable

momentary switch right into the end of the wire and putting heat shrink tubing around it. The tubing waterproofs the setup and is flexible enough to trigger the switch.

Then I fed it around the backpack straps.

No drip

Drip stop on coffee urn

Having a new HAM Radio license gets me a 1 year membership with  WARC. So, I checked out their monthly meeting this Monday. I got to meet a few interesting people and we chatted about some of the digital modes in HAM.

And, I saw the drip stop on the coffee urn. A pop bottle cut just so you could get your cup of coffee in there without problem, but drips were caught. It made me smile. It’s the kind of thing I might have come up with, and the kind of thing a lot of people would find horrible and impractical.

What is the difference between people who would embrace that and others who would mock it? I wonder if it is related to the difference between people who back into parking spots and people who don’t.
