I suck at vacation - What I did this week

Well, it seems I'm lousy at vacation. I'm still learning what I'm supposed to do. My wife is working and the kids are still in school so here was my week.

3D Printed Brackets for my new HTC Vive

I treated myself to an HTC Vive Room-Scale VR system. I'll blog extensively about this later but let me just tell you. It's AMAZING. I've used Google Cardboard, I've used Gear VR, I've used Oculus. Vive is it. Full Room-scale VR with something like the Doom 3 VR Mode is amazing. This fellow has a version of Doom 3 coded up at GitHub that modifies your existing purchased version and adds a REALLY compelling VR experience. I will say spent less time fighting demons and more time looking closely at wall textures. I admit it.

There's a joke about folks who have 3D Printers. We just end up printing brackets to hold stuff.  Well, I got a Vive so I wanted a nice way to mount it. Problem solved.

I dig #3Dprinting because you can make EXACTLY the brackets you need in a few hours!

3D Printed a Rifle Stock for the Vive

There's a popular VR game called Onward. It's basically a Call of Duty-type squad shooter with a focus on squad teamwork and realism. However, holding two VR controllers up to your cheek and pretending they are a rifle doesn't really work. Fortunately an intrepid maker named SGU7 made a prototype you can 3D Print.

I made one first in Yellow but it broken because it lacked enough infill. I made it again in black (because I had a lot of black. I wish it looked less aggressive, though) and it works great. Note that the part in my hand is a controller and the other controller is attached to the front. The front one can pop off and act as your left hand to reload and throw grenades.

It was a challenging print with five large pieces and two small along with screws and nuts to hold it together. However, it was super fun and it makes the game WAY more realistic. More on this later. I've also been experimenting with some new exotic filaments.


Made an AdaFruit Cupcade Raspberry Pi MAME Arcade

My teenage nephew and I worked on a Cupcade a few months ago but it was his. I 3d printed and made a PiGrrl (Raspberry Pi GameBoy) last year, so I figured I'd make a Cupcade (Raspberry Pi tiny Multi-Arcade Machine Emulator) as well. It's also somewhat challenging but I never really had the time until vacation. You can get the plans and source many of the parts locally, or you can get a complete kit from Adafruit. I did the partial kit for cheaper without the plastic case, then had a local makerspace lasercut a $5 piece of clear acrylic.

Set up Alexa to talk to my Nightscout-based Blood Sugar system

I got a few Amazon Alexa "Echo Dot" devices, so now we have three around the house. I upgraded my Nightscout Site (this is the Azure-based system that that allows remote management and viewing of my blood sugar as a Type 1 Diabetic.

The most recent update of Nightscout added Alexa support. I headed over to and made a dev account and got it all working. It's pretty slick. I can ask it all kinds of things (as can my kids. They love to know about how I'm doing when I'm out of town.)


Here's a video of it working!

"Alexa, what's my blood sugar?" #Diabetes @nightscoutproj #video

Basically I've been just making stuff and fixing stuff around the house. I even sat in a café and read the news. Madness.

I wonder if I could do this full time? I guess that's called retirement. ;)

The 2016 Christmas List of Best STEM Toys for your little nerds and nerdettes

November 19, '16 Comments [16] Posted in Musings
Sponsored By

Last year my 9 year old asked, "are we nerds yet?" Being a nerd doesn't have the negative stigma it once did. A nerd is a fan, and everyone should be enthusiastic about something. You might be a gardening nerd or a woodworking nerd. In this house, we are Maker Nerds. We've been doing some 3D Printing lately, and are trying to expand into all kinds of makings.

NOTE: We're gearing up for another year of March Is For Makers coming soon in March of 2017. Now is a great time for you to catch up on the last two year's amazing content with made in conjunction with!

Here's a Christmas List of things that I've either personally purchased, tried for a time, or borrowed from a friend. These are great toys and products for kids of all genders and people of all ages.

Sphero Star Wars BB-8 App Controlled Robot

Sphero was a toy the kids got for Christmas last year that they are still playing with. Of course, there's the Original Sphero that's just a white ball with zero personality. I remember when it  came out and I was like, "meh, ok." But then Star Wars happened and I tell ya, you add a little head on the thing and give it some personality and it's a whole new toy.

Sphero Star Wars BB-8 App Controlled Robot

The Sphero team continues to update the firmware and software inside BB-8 even now and recently added a new "Sphero Force Band" so you can control Sphero with gestures.

However, the best part is that Sphero supports a new system called "The SPRK Lightning Lab" (available for Android, iOS, or other devices) that lets kids program BB-8 directly! It's basically Scratch for BB-8. You can even use a C-style language called OVAL when you outgrow their Scratchy system.

Meccano Micronoids


I grew up in a world of Lincoln Logs and Erector Sets. We were always building something with metal and screws. Well, sets like this still exist with actual screws and metal...they just include more plastic than before. Any of these Meccano sets are super fun for little builders. They are in some ways cooler than LEGO for my kids because of the shear size of them. The Meccano Meccanoid 2.0 is HUGE at almost two feet tall. It's got 6 motors and there's three ways to program it. There's a large variety of Meccano robot and building kids from $20 on up, so they fit most budgets.

Arduino UNO Project Super Starter Kit from Elegoo


Arduino Kits are a little touch and go. They usually say things like "1000 pieces!"...but they count all the resistors and screws as a single part. Ignore that and try to look at the underlying pieces and the possibilities. Things move quickly and you'll sometimes need to debug Arudino Programs or search for updates but the fundamentals are great for kids 8-13.

I particularly like this Elegoo Arduino UNO Starter Kit as it includes everything you'll need and more to start playing immediately. If you can swing a little more money you can add on touchscreens, speakers, and even a little robot car kit, although the difficulty ratchets up.

Snap Circuits

Snap Circuits

I recommended these before on twitter, and truly, I can't sing about them enough. I love Snap Circuits and have blogged about them before on my blog. We quickly outgrew the 30 parts in the Snap Circuits Jr. Even though it has 100 projects, I recommend you get the Snap Circuits SC-300 that has 60 parts and 300 projects, or do what we did and just get the Snap Circuits Extreme SC-750 that has 80+ parts and 750 projects. I like this one because it includes a computer interface (via your microphone jack, so any old computer will work!) as well as a Solar Panel.

In 2016 Snap Circuits added a new "3D" kit that lets you build not just on a flat surface but expands building up walls! If you already have a SnapCircuits kit, remember that they all work together so you can pick this one up as well and combine them!


Secret Messages Kit

It's a fact - little kids LOVE secret messages. My kids are always doing secret notes with lemon juice as invisible ink. This kit brings a ton of "hidden writing systems" together in one inexpensive package. Ciphers, Braille, Code Breaking, and more are all combined into a narrative of secret spy missions.


What educational toys do YOU recommend this holiday season?

FYI: These Amazon links are referral links. When you use them I get a tiny percentage. It adds up to taco money for me and the kids! I appreciate you - and you appreciate me-  when you use these links to buy stuff.

Lonely Coding

September 30, '16 Comments [33] Posted in Musings

It's official. I'm a better programmer when I'm pairing with someone. Pair Programming (two people, one keyboard) has been around for at least 20+ years, if not much longer. Usually one person types while another person (paces around and) thinks. It is kind of a "driver and navigator" model.

Everyone is different, to be clear, so it's very possible that you are the kind of person who can disappear into a closet for 8 hours and emerge with code, triumphant. I've done this before. Some of my best projects have involved me coding alone and that's fine.

However, just has we know that "diverse teams make for better projects," the same is true in my experience when coding on specific problems. Diversity isn't just color and gender, etc, it's as much background, age, personal history, work experience, expertise, programming language of choice, heck, it's even google-ability, and more!

How many times have you banged your head against a wall while coding only to have a friend or co-worker find the answer on their first web search?

Good pair programming is like that. Those ah-ha moments happen more often and you'll feel more than twice as productive in a pair.

In fact, I'm trying to pair for an hour every week remotely. Mark Downie and I have been pairing on DasBlog on and off for a year or so now in fits and starts. It's great. Just last week he and I were trying to crack one problem using regular expressions (yes, then we had two problems) and because there were two of us looking at the code it was solved!

Why is pair programming better?

Here's a few reasons why I think Pair Programming is very often better.

  • Focus and Discipline - We set aside specific times and we sprint. We don't chat, we don't delete email, we code. And we also code with a specific goal or endpoint in mind.
  • Collective ownership - I feel like we own the code together. I feel less ego about the code. Our hacks are our hacks, and our successes are shared.
  • Personal growth - We mentor each other. We learn and we watch how the other moves around the code. I've learned new techniques, new hotkeys, and new algorithms.

Let's talk about the remote aspect of things. I'm remote. I also like to poke around on non-work-related tech on the side, as do many of us. Can I pair program remotely as well? Absolutely. I start with Skype, but I also use Google Hangouts,, TeamViewer, whatever works that day.

If you're a remote person on a larger team, consider remote pair programming. If you're an consultant  or perhaps you've left a big corporate job to strike off on your own, you might be lonely. Seriously, ask yourself that hard question. It's no fun to realize or have to declare you're a lonely coder, but I am and I will. I love my job and I love my team but if I go a day or two without seeing another human or spending some serious time on Skype I get really tense. Remote pair programming can really reduce that feeling of lonely coding.

I was at a small tech get together in Atlanta a few days ago and I knew that one person there was a singular coder at their small business while another at the table was an emerging college student with an emerging talent. I made a gentle suggestion that maybe they consider pairing up on some side projects and they both lit up.

Consider your networks. Are there people you've met at conferences or at local user groups or meetups that might be good remote pairing partners? This might be the missing link for you. It was for me!

Do you pair? Do you pair remotely? Let us all know in the comments.

How to deal with Technology Burnout - Maybe it's life's cycles

September 6, '16 Comments [41] Posted in Musings

Burnout photo by Michael Himbeault used under cc

Sarah Mei had a great series of tweets last week. She's a Founder of RailsBridge, Director of Ruby Central, and the Chief Consultant of DevMynd so she's experienced with work both "on the job" and "on the side." Like me, she organizes OSS projects, conferences, but she also has a life, as do I.

If you're reading this blog, it's likely that you have gone to a User Group or Conference, or in some way did some "on the side" tech activity. It could be that you have a blog, or you tweet, or you do videos, or you volunteer at a school.

With Sarah's permission, I want to take a moment and call out some of these tweets and share my thoughts about them. I think this is an important conversation to have.

This is vital. Life is cyclical. You aren't required or expected to be ON 130 hours a week your entire working life. It's unreasonable to expect that of yourself. Many of you have emailed me about this in the past. "How do you do _____, Scott?" How do you deal with balance, hang with your kids, do your work, do videos, etc.

I don't.

Sometimes I just chill. Sometimes I play video games. Last week I was in bed before 10pm two nights. I totally didn't answer email that night either. Balls were dropped and the world kept spinning.

Sometimes you need to be told it's OK to stop, Dear Reader. Slow down, breathe. Take a knee. Hell, take a day.

Here's where it gets really real. We hear a lot about "burnout." Are you REALLY burnt? Maybe you just need to chill. Maybe going to three User Groups a month (or a week!) is too much? Maybe you're just not that into the tech today/this week/this month. Sometimes I'm so amped on 3D printing and sometimes I'm just...not.

Am I burned out? Nah. Just taking in a break.

Whatever you're working on, likely it will be there later. Will you?

Is your software saving babies? If so, kudos, and please, keep doing whatever you're doing! If not, remember that. Breathe and remember that while the tech is important, so are you and those around you. Take care of yourself and those around you. You all work hard, but are you paying yourself first?

You're no good to us dead.

I realize that not everyone with children in their lives can get/afford a sitter but I do also want to point out that if you can, REST. RESET. My wife and I have Date Night. Not once a month, not occasionally. Every week. As we tell our kids: We were here before you and we'll be here after you leave, so this is our time to talk to each other. See ya!

Thank you, Sarah, for sharing this important reminder with us. Cycles happen.

Psychic Weight - Dealing with the things that press on your mind

August 24, '16 Comments [45] Posted in Musings
Sponsored By
Close up view of man on his phone 

I was really stressed out ten years ago. I felt that familiar pressure between my eyes and felt like all the things that remained undone were pressing on me. I called it "psychic weight." I have since then collected my Productivity Tips and written extensively on the topic of productivity and getting things done. I'm going to continue to remind YOU that Self-Care Matters in between my technical and coding topics. The essence of what I learned was to let go.

The Serenity Prayer:

God, grant me the serenity to accept the things I cannot change,
Courage to change the things I can,
And wisdom to know the difference.

Everyone has stress and everyone has pressure. There's no magic fix or silver bullet for stress, but I have found that some stressors have a common root cause. Things that stress me are things I think I need to do, handle, watch, take care of, worry about, sweat, deal with, or manage. These things press on me - right between my eyes - and the resulting feeling is what I call psychic weight.

For example: When the DVR (Digital Video Recorder) came out it was a gift from on high. What? A smart VCR that would just tape and hold all the TV Shows that I love? I don't have to watch shows when the time and day the shows come on? Sign me up. What a time saver!

Fast forward a few years and the magical DVR is now an infinite todo list of TV shows. It's a guilt pile. A failure queue. I still haven't watched The Wire. (I know.) It presses on me. I've actually had conversations with my wife like "ok, if we bang out the first season by staying up tonight until 4am, we should be all ready when Season 2 drops next week." Seriously. Yes, I know, Unwatched TV is a silly example. But you've binge-watched Netflix when you should have been working/reading/working out so you can likely relate.

But I'm letting go. I'll watch The Wire another time. I'll delete it from my DVR. I'm never going to watch the second season of Empire. (Sorry, Cookie. I love you Taraji!) I'm not going to read that pile of technical books on my desk. So I'm going to declare that to the universe and I'm going to remove the pile of books that's staring at me. This book stack, this failure pile is no more. And I'm not even mad. I'm OK with it.

Every deletion like this from your life opens up your time - and your mind -for the more important things you need to focus on.

What are your goals? What can you delete from your list (and I mean, DROP, not just postpone) that will free up your internal resources so you can focus on your goal?

Delete those emails. Declare email bankruptcy. They'll likely email you again. Delete a few seasons of shows you won't watch. Delete Pokemon Go. Make that stack of technical books on your desk shorter. Now, what positive thing will you fill those gaps with?

You deserve it. Remove psychic weight and lighten up. Then sound off in the comments!
