Hackaday+Tindie Maker Faire Meetup

We had a great time last year and recommend folks at Maker Faire Bay Area 2017 come  to this Saturday night meetup hosted by Hackaday and Tindie:

It’s Maker Faire Bay Area time of year again and we’re holding our 4th annual Hackaday and Tindie MFBA Meetup!

After a ridiculously fun Saturday at Maker Faire, carry on the festivities with us at O’Neill’s in San Mateo on Saturday night from 7pm.

Bring your finest blinky, flashy, IoT, hacks, wearables, or other techy items for us to paw. Bonus points if you bring your #HackadayPrize project for us to get super excited about.

We can’t wait to see you there or at the faire.

Space is limited, so get your foot in the door early. 21 or over only. Please bring ID.

Tindie Seller Interview: Jakub Polonský and His “MightyWatt” Load

Jakub Polonský and His “MightyWatt” Load

There are people of diverse backgrounds selling on Tindie, but as far as I know, Jakub Polonský is the only one here with a PhD in electrochemistry. Though this gave him a good background in testing of electronic quantities for electrochemical systems, as far as designing electronics, he’s self taught. He graduated in 2012, but started with Arduino boards in 2010, allowing him to use this versatile tool for research purposes.

Check out our previous blog post for more information on the project:

Orthrus: secure two-card storage

From Nick Sayer on Hackaday.io:

Orthrus: SD card secure RAID USB storage

This project is a hardware mechanism to provide secure “two man control” over a data store. It is a USB microSD card reader, but it requires two cards. The data is striped in the style of RAID 0, but the data is also encrypted with a key that is stored in a key storage block on each card. In essence, each card is useless without the other. With possession of both cards, the data is available without restriction, but with only one, the remaining data is completely opaque.

This allows you to securely transport a data set by writing it onto a pair of cards and separately transporting them to a destination for recombination.

The intent is that only the pairing of two cards becomes in any way special. A card pair could be inserted in any Orthrus device and the data would be made available. But with only one card, all you get is half of the data encrypted with a key which you only half-possess.

The firmware source code is available on GitHub:

SIS-2 Universal Remote Receiver

Jeremy Cook writes on the Tindie blog about this IR receiver board by Atomsofttech:

SIS-2 Universal Remote Receiver

When you think of a “universal remote,” you generally picture an infrared (IR) emitter that can be setup to control your TV, AV receiver, and any other number of devices that work using IR signals. On the other hand, what’s to keep someone from doing the opposite, and having a universal receiver that can be programmed to accept codes from a remote that you just have lying around?

Vertically Mounted Arduino-Compatible Board

Clovis Fritzen designed this Arduino-compatible, vertically-mountable board that exclusively uses through-hole components:

arduino-vertical-676x507

Vertically mounted Arduino for Breadboard

I personally love the concept of electronic boards connected in “slots” (vertically attached to a horizontal board), like most industrial-grade PLC’s or even our desktop’s expansion cards (video, sound memory): it saves a lot of space and adds more functions to the system, all at once!

 

The PCB is for sale on Tindie:

tindie-logo2x

Vertically mountable Arduino – PCB only

This is an Arduno-Nano compatible controller that can be vertically mounted to bredboards and boards

Analog CPU Gauge

Adam Fabio created this analog gauge to show your computer’s CPU utilization:

Analog CPU Gauge

The goal of this project was to build an analog gauge to display computer CPU utilization. I’ve always been fond of classic analog gauges. Most CPU Gauges are either digital on screen displays, or implemented with an LCD mounted in a drive bay

I’d always wanted a CPU gauge for my computer. Ok, and a bandwidth gauge for my router. You name it, I want a nice analog gauge for it. It always seemed a bit silly to use an true galvanometer based analog gauge for signals that are inherently digital.
