NEW PRODUCT – Adafruit TPL5110 Low Power Timer Breakout

NEW PRODUCT – Adafruit TPL5110 Low Power Timer Breakout

With some development boards, low power usage is an afterthought. Especially when price and usability is the main selling point. So what should you do when it’s time to turn around and make that project of yours run on a battery or solar? Sure you could try to hot-air that regulator off, or you could jerry-rig a relay. Or, use a 555? Ugh, the options aren’t that great.

The Adafruit TPL5110 Power Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of turning your project on/off using a built in timer that can vary from once every 100ms up to once every two hours. Basically, the TPL will turn on periodically, adjustable by potentiometer or resistor, and turn on your project’s power. It will then wait until a signal is received from the project to tell the TPL that it can safely turn off the power.

Usage is easy. First, set your desired delay by adjusting the on-board trim pot: nearly-all-the-way-to-the-left is “once per 100ms” and all-the-way-to-the-right is “once every 2 hours”. Then, connect VDD up to your 3-5V power supply and then your project’s power-in to the Drive pin. Finally, select a signal pin from your project to the Done pin. In your project’s code or design, just make sure that it sets the Done pin high once it is completed with its task. That’s it!

While the TPL5110 is running (but the remainder of the project is de-powered) the current draw is about 20uA (according to our Monsoon Power Meter).

If you want to turn the device on by hand, you can also activate the TPL by pressing the onboard tactile switch (or wire your own switch to the Delay pin). See? Your power problems just got solved!

Comes as a fully assembled breakout board with a TPL5110 chip, all components on-board, and some header. A little light soldering is required to put it together for breadboard use.

In stock and shipping now!

Undertale Mettaton Costume Looks So Metal

AdaFruit - Thu, 03/09/2017 - 08:00

As a robot with a soul, Mettaton starts out in Undertale as a gray box. Then he evolves into Mettaton EX. The humanized version is the one Katelyn Jones Cosplay went with. She replicated the character’s metallic looking makeup with body paint and a silver stretchy fabric. Katelyn crafted the spandex suit and embellishments. The armor pieces started as EVA foam that Katelyn fitted onto a duct tape mannequin. You can see a couple of making-of photos below.

Es un remix de “Extending Wolverine Claws by atartanian ” cambiando la sujeccion al interior de la mano, asi quedan ocultas y solo salen para desgarrar!
Tambien se le añadio una ranura para sujetartelo con una cinta.

Nota: Falta la tapa trasera, yo por prisas la hice con deseschos de plastico y cinta.

This is a USB desk grommet for 1-3/4″ (about 45mm) round holes. I designed it to hold a bulkhead / panel mount USB extension cable for a one button studio that we designed. It’s a handy way to mount a USB extension to a small equipment rack or piece of furniture.

Geoffrey shared this project on Thingiverse!

Printed in Torwell’s purple PLA.

In the Hairy Walrus make I did, lowlight said “hmmm this makes me think of Unicorn manes/tails and gnome beards cant be far off in the future.”

and I thought yeah that’s actually a good idea and so here is a Hairy Unicorn. If you have a good idea for something hairy let me know in the comments and it might make the next one! Perhaps the gnome next who knows if I can get some time.

This is a pretty simple and quick print, mine took 1 hour and 48 minutes.

Raspberry Pi Zero Camera Holder #3DPrinting #3DThursday

AdaFruit - Thu, 03/09/2017 - 03:00

robohead456 shared this project on Thingiverse!

A simple mount to hold a Pi Camera to a Raspberry Pi Zero.

The camera is attached using M2 bolts, preferably nylon as metal bolts could short the Pi.

The Pi is attached using M2.5 bolts. In my photos I used M3 bolts because I didn’t have any M2.5 bolts available. If you want to use M3 bolts you will need to use a drill bit to make the mounting holes in the Pi and the printed parts larger.

Ultimaker 2 Bowden Hook #3DPrinting #3DThursday

AdaFruit - Thu, 03/09/2017 - 01:00

yyh1002 shared this project on Thingiverse!

A hook to restrain the movement of Bowden tube and cable on Ultimaker 2.

UPDATE:
Version 3 features adjustable position for the hook. It also allows the tube to move in Y axis to reduce unnecessary bending. The length is slightly shorter than the spool holder.

Past versions:
Version 1 and version 2 has different position of the hook. 1 goes more to the left, and 2 goes more to the right.
Both v1 and v2 restrain the tube to the edge of the printer, which would create extra bending while the printhead reset to home position.

From the mail bag!

Just a general comment back to you guys. I’ve been involved
in electronics all my life and allays wondered why there’s none or at least very few women who are interested in this field. I was just ordering some gear and new to your business wondered where the name came from. This lead me to read about Limor Fried. What an awesome story.

Cheers,

Stephanie Lampkin, Founder and CEO of the ‘Blind Recruiting’ App, Blendoor #WHM17 #WomensHistoryMonth #WomenInSTEM

AdaFruit - Wed, 03/08/2017 - 23:30

Stephanie Lampkin is the founder and CEO of Blendoor, a platform for merit based hiring.

From Fast Company’s recent article on Stephanie Lampkin:

…By 13, she was learning to code. She took AP Computer Science in high school and earned a scholarship to Stanford. After graduation Lampkin landed a job at Microsoft. On the surface, it seemed that she’d made it. “I bought a house when I was 21, and spent more than five years at Microsoft,” says Lampkin. “I learned a lot, but I didn’t see a lot of opportunities to grow.”

So Lampkin went back to school. At MIT’s Sloan School of Management, she earned an MBA with a concentration in entrepreneurship and innovation. Despite her advanced degrees and work experience, she still faced barriers. Six months after receiving her MBA, she nearly landed a lead analytics position at a major tech company but was told they’d keep her resume on file for sales and marketing openings, instead.

By that point, she had not only worked at Microsoft, but also Lockheed-Martin and Deloitte, in software and technical-related roles. Yet here she was, still being told she didn’t have the tech credentials.

Lampkin was not only having a hard time breaking out of women-based stereotypes, but even when she was a finalist for jobs, she was losing out to white and Asian men. At one point, she’d discovered she was making 20 percent less than a male colleague in the same role despite having better performance metrics. Lampkin knew she wasn’t the only one experiencing these challenges. A 2015 report by Joint Venture found that men in Silicon Valley earned as much as 61 percent more than their female counterparts. The more doors that were slammed shut for her, Lampkin says, the more the bias “was difficult to ignore.”

PERFECT MATCH

Determined to redress the bias, Lampkin conceived Blendoor. She spent two years developing the app and finally launched in public beta in March 2016. For candidates, it provides a chance to showcase their qualifications to top employers with just a swipe. Blendoor has signed on more than 400 companies, including Salesforce, Yelp, Google and Microsoft, giving them access to about 10,000 candidates. The companies not only have access to a diverse pool of qualified candidates, but they also receive data and analytics to assist their inclusion efforts beyond recruiting. “Today, we’re more enterprise-focused than ever,” Lampkin says.

From the start, people in tech have recognized how innovative Blendoor really is. A high point came in November 2016, when Lampkin’s app won the audience-favorite “Game Changer” award at Google Demo Day. “The audience votes for the startup most likely to disrupt its industry,” notes Becca Sampson, the lead planner for Google Demo Day. “Last year, the Demo Day audience clearly felt that Blendoor had the most potential to change the industry of hiring and recruiting.
