Micro SD Extension Cable

Weirdly, one problem with memory now being so small is that these drives can be placed in areas that are difficult to access. Usually this means some sort of USB adapter (another amazing improvement over serial or parallel ports), but if you just want an actual SD extension cable in the form of a micro SD card, here it is! This device was conceived of when programming a BeagleBone Black, and could have lots of other applications.

I designed this little tool while compiling a software installation on BeagleBone Black. I needed to repetitively remove/inset the micro SD card. The BeagleBone was installed in a hard-to-reach area. So much time was wasted trying to inset the card with tweezers.

This simple tool plugs into the hard-to-reach socket, and provides a flexible extension.

Length: 3.5″

Learn to Surface Mount Solder with Sean Hodgins

Sean Hodgins has a great tutorial on surface mount soldering:

Learn to Surface Mount Solder Using an SMD Challenge PCB

I feel like surface mount soldering has a bad reputation. It can seem daunting to someone who has never tried it. Since a lot of my project involve using surface mount components, I thought it would be a good idea to make something to inspire people to try it out (without risking expensive components or their custom project).

Decide how you want to assemble your SMD Challenge Kit (re, the video) you can choose to use a soldering iron, or a reflow oven. They take about the same amount of time but using the soldering iron can be a little more challenging and doesn’t require a cheap toaster oven.

TeensyStep: Fast Stepper Library for Teensy

The Teensy platform is very popular with hackers — and rightly so. Teensys are available in 8-bit and 32-bit versions, the hardware has a bread-board friendly footprint, there are a ton of Teensy libraries available, and they can also run standard Arduino libraries. Want to blink a lot of LED’s? At very fast update rates?…

Advanced soldering training at Maker Faire Orlando

For the past six years at Maker Faire Orlando, members of FamiLab have taught attendees how to solder with a cool little Makey pin with 2 self-flashing LEDs.  We’ve been asked for more advanced soldering training, and we responded with the addition of a PIC-microcontroller-based board twinkling several LEDs, and with a switch that can be used to change the LED display pattern.

We opted to design the board such that it can be used as a pendant on a necklace (lanyard) or as a keychain (especially for those of you who like large keychains). The design is a scalloped 2.7″ circle with LEDs on the outside circle, and a hole at the top for a keyring. Batteries are on the back of the board.

This weekend, October 21st & 22nd, is Maker Faire Orlando!Screenshot from 2017-10-17 22-22-56

Maker Faire Orlando is a non-profit, community-organized, family-friendly celebration featuring local do-it-yourself science, art, rockets, robots, crafts, technology, music, hands-on-activities, and more. It’s an event where people show what they are making and share what they are learning.

The individuals behind these exhibits are known as “Makers” and they range from tech enthusiasts to crafters to homesteaders to scientists to garage tinkerers. They are of all ages and backgrounds. The aim of Maker Faire is to entertain, inform, connect and grow this community.

We’ve been busy prepping the Central Florida Fairgrounds & Expo Halls for Maker Faire Orlando 2017! Now you can check out the official program or mobile apps (iOSAndroid) for information about Maker Faire including featured exhibits, hands-on workshops, and schedules for Combat Robots and Power Racing.

Hackaday Prize Entry: Giving Phones Their Tactile Buttons Back

In the before-times, we could send text messages without looking at our phones. It was glorious, and something 90s Kids™ wish we could bring to our gigantic glowing rectangles stuck in our pocket. For his Hackaday Prize Entry, [Kyle] is bringing just a little bit of this sightless functionality back to the modern smartphone. He’s…

SAMD21G Sensor Board with Color OLED

This Sensor Board is yet another variation of another one on my site. It is not for sale with no real purpose in mind but the design files to make your own are here. The project was created as design challenge. My full time job is pcb design work and as a hobby I enjoy experimenting with new design ideas.

This was one of the more challenging designs I’ve worked on in a while. A few times I’d given up on routing it. Evan using four routing layers I found it tough. The idea was to hide the bezel of the display behind the board but have sensor components on that same board. It would look something like a little tiny television with all the components around the edges.

This latest revision has fixed a few issues I found on previous versions but the design idea can possibly help others in some way. Full credit goes to Adafruit for publishing the Feather M0 design files along with the bootloader. I used the Feather design to create the schematic for my board.
