This week on Maker Update, a Neopixel trampoline,
pocket power supply, a mirrored arcade cabinet, light-up fingernails, Pixel Time, and a psychedelic
scuba mask. I’m Donald Bell and it’s time for another
Maker Update. This week, I’m going to try something new
and instead of covering 2 or three new projects, I’m going to quickly run through 6 of them. So brace yourself, and let me know what you
think. My favorite project this week is this LED
trampoline by the Ruiz brothers on Adafruit. They’ve rigged it up so that with each bounce,
a ring of LED stip set in the trampoline will flash different colors or trigger animations. The project uses a length of Neopixel LED
strip connected to one of Adafruit’s new $12 ItsyBitsy M0 Express boards. A $1 vibration sensor is triggered with each
jump, which the board takes as an input and activates the LEDs. Everything is powered from a portable USB
power bank just to keep things simple. It’s a fun project, especially for kids,
and one of those projects that I’ll be surprised if there isn’t a commercial version of this
idea soon. More projects! Over on Instructables, Lonesoulsurfer has
a guide on making a pocketsize variable power supply using a 9 volt battery, voltage meter
display, a potentiometer, banana plug sockets, and these cheap voltage regulator boards you
can get for $1 on eBay. It’s not the most practical design since
it will suck up 9v batteries, but if you need something small and portable as part of an
electronics kit, it’s a neat idea. Also just cool to know about those cheap voltage
regulator boards. I also got a kick out of seeing this custom
arcade cabinet made for an indie space shooter game called Grotoro. It’s basically just a box with a monitor
mounted on one end and controls built into the bottom side. But by using reflective paper on the inside,
the screen’s image is multiplied to give it a whole different feel. The game itself is downloadable for Windows
for whatever price you feel like paying for it. Back on Adafruit, Sophy Wong has a guide on
making a Neopixel LED manicure. She’s using these tiny, individual Neopixel
Nano LEDs, wiring them up to each other and a Gemma M0 board, loading up some included
Circuit Python code, and then super gluing them to acrylic nails. It’s a super cyberpunk look, though probably
not the most practical considering all of those wires. Dominic Buchstaller has a writeup on version
2 of his Pixel Times display. It’s a 32×16 grid of multicolor pixels that
works as a clock, or weather station, or just displays cute pixelated animations. The design is built around what’s called
a P10 LED panel, commonly found as part of a large electronic billboard. It’s a loose grid of addressable LEDs and
they’re cheap — around $15. By placing a 3D printed grid of plastic over
each LED, Dominic’s design isolates the light of each light, creating these well-defined
pixels. Behind it all is an inexpensive NodeMCU board,
which uses Wi-Fi to pull down time and weather data, and load up new animations. And for the last project here, Curt White
made this Infinity Mirror scuba mask that has a small hole cut out so that you can actually
see through it. The project uses a dense strip of WS2812b
LEDs or Neopixels, a Jacques Cousteau style scuba mask, a AA battery pack, an Arduino,
a switch, a sheet of mirrored acrylic, and an optional accelerometer for making the animation
responsive to body movement. I’m not sure what I’d use it for, but
it might be good to have on handy as a last minute psychedelic scuba costume. It’s time for another Cool Tool review. This time we’re taking a look at a socket
bit adapter set for a drill or impact driver. These cost me around $8 on Amazon, and if
you want to pick some up for yourself you can use the Amazon link in the description
which helps support my videos and the Cool Tools blog. For reasons I don’t understand, my socket
wrench set and most of the sets I see on Amazon, don’t include a basic adapter for dropping
a socket bit into a drill or impact driver. This is dumb. Fortunately, you can fix this oversight for
around $8 and get a set of adapters that will fit 1/4″, 3/8″, and 1/2″ sockets. Now you can just pop a socket onto the correct
adapter, chuck it in your drill or driver, and make quick work of nuts and bolts. Whenever I use this, I feel like I’m part
of a NASCAR pit crew. There’s nothing fancy about them, and I
can’t think of any reason you’d need to pay more to get a better result. If you’re lucky, you can find a place to
keep them in your socket wrench set. Mine tuck right in under the wrench, which
helps me keep everything together. That’s all there is to it. Such a simple thing, but I wish I’d gotten
them sooner, and I wish more socket sets just came with these. You can grab the same ones using the link
in the description. And remember, you can see thousands of reader
recommended tools like these at Two last things to share with you. If you have a 3D printer and you use Octoprint
as a wireless server to feed it designs, there’s an Octoprint plug-in called Octalapse that
allows you to create these timelapse videos of your prints that makes it look like they
just grow magically. Because the timelapse software can synchronize
with the printer, it only ever takes a picture when the print nozzle is out of the picture. It’s cool, right? And if you remember from a few episodes ago
I talked about those funky looking thumb pianos made by Loek Vellekoop. Well I’m talking with him today live on
YouTube at 11am Pacific. I’ll include a link where you can watch
it live and ask a question, or see the archived recording. Maker Faires! There’s an insane amount of faires this
weekend including New Orleans, Louisiana; Bloomsburg, Pennsylvania; Westport, Connecticut;
Bowling Green, Kentucky; Dnipro, Ukraine; Albuquerque, New Mexico; Utica, New York;
South Bend, Indiana; Kadikoy, Turkey; and Roanoke, Virginia. Seriously, one of those have got to be nearby,
so go check it out. And that does it for this week’s show. Did you like having more projects covered
in less depth? Or fewer projects with more breakdown? Let me know by leaving a comment. And like always, be sure to subscribe and
leave me a thumbs up. Join the Maker Update email list to get show
notes and and even more projects. Get some socket bits for your drill. And if you really appreciate the work I put
into these, you can buy me a coffee. Alright? Thanks for watching, and I’ll see you next

    Please do a lot of projects and less depth. We can use your show notes 📝 to look up any thing we like. Love the show

    I like the new format! Enough detail to understand what's going on, and easy to go and find out more. Pixel Times was my fave this week, and access to a laser cutter would make making the overlay grid simple!

    Go Bears!

    Yes, I prefer more projects, quickly (honest translation: it increases the chance of me being in the show! 🙂

    Like the 'lot of projects' approach. If there's something really unique then maybe trim the list but it's better to see more! Also you could do a 'top 5' separate video out of these (just like you did back in the day;) Keep up the good work Donald!

    Totally like the format change. More projects is always like more brain candy. FYI, featuring one of the components of one of the projects, like the Pixel board or the inexpensive voltage regulators, as your "Cool Tool" would totally make me motivated to go buy them. I always go look them up.

    Loved the speedy approach!

    Lot of projects reviewed with links in the notes, good. But, of course, we'd also like longer in depth presentations of projects you make yourself.

    Daughter walks in during trampoline segment, folds monitor faster than naughty pics. Awesomeness, but Daddy ain't got them kind of skills… 🙂

    The more projects the better! If finding more projects is tough, the old format kills too!

  • April 19, 2018 at 3:32 am

    Bloomsburg here I come!!!

    I like the shorter recap of more projects!

    Thanks for sharing!

    MOAR = good! But flex the formats so they're less of a drain…I appreciate your volunteer efforts on this (many of us) enjoy!

    Hi Donald, like the new format but the old one with less projects in more detail was nice as well. So do what you think is best.

    Only one critical note about the adapter. If you use it with your impact driver there is a big chance you will ruin your sockets because they are not impact proof… Just thought is should let you know.

    The better tool brands have specific sockets that are made to last with impact drivers.
