DIY MagSafe stand

So there are fifty to one hundred dollar stands that hold a MagSafe puck for your phone on your desk. Save your money – this is a 20 dollar stand with a MagSafe attached using two 3M Command Strips.

Less classy

I got the stand from Amazon(non referral link). Tablet Stand Adjustable, Lamicall. The strips are “Command Poster Hanging Strips Value-Pack, Small, White, 48-Pairs (17024-48ES)” which are eight dollars for 48, I used two here to hold the puck firmly. The magnets in the puck are strong, so this provides enough adhesion to keep it in place when I pull the phone away.

Simple, cheap, and the 3M strips remove cleanly for when things change. I can now just drop my phone here as I work and it’s visible and topped off. The AirPods also work well.

Thoughts on the Amazon re:MARS 2019 conference

The usual disclaimer: my employer paid for me to go, but this is my personal take, etc.

TL;DR: hell of a show, varied tech content, unusual breadth and amazing audience. Crazy attention to branding.

So most of the conferences I attend are tech focused: PyCon, Supercomputing, Google I/O, that sort of thing. re:MARS is machine learning, AI, robotics and space, which is why I went, I’m a machine learning engineer these days. But the audience was wild – I met CEOs of aerospace companies, the head of robotics strategy at Amazon and dined with the CTO of a mid-cap German tech company. I can’t recall any tech conference with such good C-level attendees and I really appreciated the opportunity to talk as peers. Or at least fellow attendees. And having Robert Downey Jr as keynote was… boss.

Many of the talks were transparently ads for services or companies. Blech. Some were excellent- the DeepRacer half day was great. I liked very much some of the Ground Truth and Ground Station talks… and wow are those a span. Who’d have anticipated the bookstore becoming a purveyor of 10gbit satellite downlinks?

Machine learning is hugely dominant throughout as expected, with an interesting explanation from a VP that every single project has to explain in their OP-1 plan how they’ll use ML. It’s a requirement now! So if you’re not onboard yet, they opened up their ML course – free!

The expo floor was quite cool and over half cool robotics. And spaaaace.

Cool indeed.

And a selfie bot.

As is often the case, it was 100F outdoors and downright chilly inside. Pro tip, always pack a light layer. Your mom was right.

Show floor:

Someday I’ll have a robotic lawnmower.

Rivian had their truck there and I drooled on it. Presumably unaffordable though.

The weather was Vegas summer. I promptly gave up the idea of finding a beach volleyball game as suicidal.

The motor speedway party was epic. The pace car ride was a total blast, being driven 122MPH in, of all things, a stocky Camry SE driven by a former racer. Zoom zoom indeed.

The battlebots bored me, to my surprise. No seats left.

I only sorted this out at the end, but in retrospect Amazon went to astonishing lengths to brand everything. It’s amazing. So signs of course.

Note the odd size and shape. But covering all logos on the wireless gear? On a 15m ceiling mount even?

And the podiums.

And the monitors. All blanked out. Ditto all loudspeakers. An impressive, Steve Jobsian level of attention to detail and message. Tour busses even go co-branding.

The mock space capsule was fully awesome.

My employer got some great mentions –

Though I am biased, I think it’s true that Intuit is doing cool stuff in ML. End advert.

Oh yeah, this is tasty and I need to buy some.

If you’ve questions, leave a comment and I’ll answer or append here.

Should you go? Tough call if you look at just ROI – you don’t learn as much tech but the crowd might well be a sound investment. Some of the space talks, for example, had an amazing audience of experts and entrepreneurs. I’ve got an idea for a startup now based on SAR data that I need to investigate, so maybe that’s my personal takeaway. I’m really glad that I got to go.


Wyze camera

This thing is awesome. Think cheap machine vision experiments, doorbells, baby monitors, time-lapse, home security. 1080p, wireless, with sound and more.

The hardware is a small cube, here on the shelf:

The iOS app is good, here’s a screenshot:

And it saves to device with a click:


Night vision works pretty well with four 0.5W IR LEDs. And you can even use it as a webcam/intercom or baby cam. And an SD card to record.

It can trigger based on motion and send push notifications but I’ve yet to try that.


Limited to about 10 fps.

Needs WiFi and power.

No Ethernet.

Frequently out of stock on Amazon.

But damn, at $30 who cares? Head on over to Amazon and buy one to try.
