When your old favorite things became useless you can give them a new life. Estonian designer Pavel Sidorenko did it. He took old vinyl records and transformed them into extremely beautiful wall clocks. All silhouettes from his collection “Re Vinyl” are simple and well recognizable. You could find here urban landscape, teapot and even rhino. Take a look at whole collection and choose your favorite one!
BACK IN STOCK – USB LiIon/LiPoly charger – v1.1! This is a Lithium Ion and Lithium Polymer battery charger based on the MCP73833. It uses a USB mini-B for connection to any computer or ‘USB wall adapter’. Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up. The fast-charge current is 200mA by default, but is easily adjustable from 100mA up to 1000mA by soldering a through-hole resistor on-board. This board is great for DIY projects because it has 3 indicator LEDs – one for power, one for charging status and a third that indicates when charging is complete. Keep the battery connected to the charger and pass power through the additional JST connector using the included cable!
Comes assembled and tested with a free bonus JST cable!
5V input via mini-B USB connector
For charging single Lithium Ion/Lithium Polymer 3.7/4.2v batteries (not for older 3.6/4.1v cells)
200mA charge current, adjustable up to 1000mA by soldering in a resistor
Separate JST connectors for battery and load system so batteries don’t have to be removed for charging
Chip supports a 10K thermistor which we have stuffed as a plain 10K. For people who require temperature monitors (using high charge rates), remove the 10K and solder in the thermistor in its place
0.1″ (2.54mm) pads next to the JST in case you want to use terminal blocks or connect it to a breadboard
Free 2-pin JST cable included!
Battery and USB cable not included (but they’re available in our store).
And these two books are back in stock too!
Practical Arduino (Jon Oxer & Hugh Blemings)
This book is best used for people who’ve gone through our tutorials and want more! Please note that the book does not come with any electronic parts or hardware. You’ll probably want an Arduino starter pack or similar so that you have the Arduino, USB cable, power adapter, wires, and a protoshield. Read more…
Make: Electronics (Charles Platt)
We checked out this book before putting it in the shop, its geared towards ultimate-beginners and teaches electronics starting from basic core of analog to some digital to microcontrollers. You’ll learn tools, prototyping soldering techniques, transistors, 555′s, etc. while completing useful projects. A nice and tidy intro! This book is a good accompaniment to learning microcontrollers/Arduino in that it fills the necessary electronics theory and background. Read more…
OK, I know that sounds weird, but bear with me for a moment. My Pops really enjoys two things; 1) channel surfing and 2) farting.
So one day I was over at http://hackaday.com/ and read about a guy who used his Arduino to turn a TV on and off with one of those brainwave reading headsets. Then later on that same day I was here at Instructables and a fellow had made an office chair that twitters every time he farted. So, I got to thinking and decided to mash those two hacks into one remote that changes the TV to a random channel every time he tutes!
Plus, if you throw it in a plastic enclosure and hide it between the couch cushions; you’ve got a purdy dang good prank!
(As an aside, I’ve done some internet searching and I think this might be the first flatulent operated remote control in the history of the world… I’m happy to be an innovator.)
Its been a long road. Seventeen months, countless hours, multiple dead ends, hundreds of lessons learned, and one helmet made. In the past two installments I’ve discussed sculpting, resin casting, chroming and vacuum forming. This is where the magic happens though… Illumination.
Every Thursday night at 8pm EST join redcell, psytek and osiris for our weekly live video & “chatroom” “Ask a Hacker“. Bookmark this page to view the “live” video and chatroom – or visit our USTREAM page. You can ask anything about hacking, hackerspaces or just stop in to meet other hackers who are hacking things. At the end of the chat we give away an Alpha One Labs t-shirt to the winner of our trivia question. If you would like to connect to our chat via IRC here are twohow-tos. We are #alphaonelabs on IRC server irc.freenode.net
Alpha One Labs hackerspace was founded in the summer of July 2009. Boasting radical inclusivity, Alpha One Labs superb design aims to provide a safe, clean space for users of all ages and interests to work on projects together. Contact us to set up a visit and learn more about our new membership specials.
After seeing our photomask coasters, a friend gave us this giant photomask as an art piece. While we’re not certain what this was for, our best guess is that it is a mask for the lead frame for some device in an SO-20 package. The overall size is about 18″ x 24″ and about 1/8″ thick.
Andrew Plumb (aka aplumb and clothbot) has been experimenting with making LEGO-compatible blocks for awhile. We talked about his work on here back in December, and he has done some more great work since then. Our last post mentioned the laser cutting files he uploaded to Thingiverse, and above you can see some of those digital files made real with our own beloved laser cutting service, Ponoko Designmake.
He has also had some parts 3D printed through Shapeways, and they are even available for sale through his Shapeways Shop.
Custom LEGOs… oh to be 7 years old again (with access to a 3d printer).
Did you know you could be a rocket scientist in just one day? Well, a hobby rocket scientist anyways! The field of hobby rocketry is huge, ranging from $5 mini starters to multi-thousand dollar custom made giants that can fly thousands and thousands of feet. Today we’ll show you enough to get you up in the air and crashing in no time!
Sylvia’s Super-Awesome Maker Show – Maker Faire edition!
Dear Ladyada (Limor), Thank you soooo much for signing my autograph book. I know you were busy and had lots of things to do, but you still gave me some time! Thank you!! You are so amazing for all the cool electronic and crafty stuff you work on. It’s hard to find other girls who like electronics and robots and stuff anywhere, but your stuff helps me and dad says you’re a great role model. We bought your motor shield and the wave shield for our little robot. I helped solder both of them and maybe soon we’ll have our little bot rolling and talking!

Rereko is just your average high-school girl from Electopia, the land of electricity, but she’s totally failed her final electricity exam! Now she has to go to summer school on Earth. And this time, she has to pass. Luckily, her ever-patient tutor Hikaru is there to help. Join them in the pages of The Manga Guide to Electricity as Rereko examines everyday electrical devices like flashlights, heaters, and circuit breakers, and learns the meaning of abstract concepts like voltage, potential, current, resistance, conductivity, and electrostatic force.
The real-world examples that you’ll find in The Manga Guide to Electricity will teach you:
What electricity is, how it works, how it’s created, and how it can be used
The relationship between voltage, current, and resistance (Ohm’s law)
Key electrical concepts like inductance and capacitance
How complicated components like transformers, semiconductors, diodes, and transistors work
How electricity produces heat and the relationship between current and magnetic fields
If thinking about how electricity works really fries your brain, let The Manga Guide to Electricity teach you all things electrical in a shockingly fun way.
About the Author
Kazuhiro Fujitaki is a lecturer at the Tokyo Metropolitan Vocational Skills Development Center. He has written a number of books on electrical engineering and runs a website offering useful information about Japan’s qualifying examinations for electrical technicians.
The purpose of this project was to provide an inexpensive communications network that does not rely on pre-existing infrastructure. Currently the system utilizes wind and solar energy to power a wifi repeater and VOIP phone. The power produced by the wind turbine and solar panel is monitored remotely using a hall-effect sensor and microcontroller.
The proposed system relies on access (through multiple repeaters if necessary) to an internet uplink in order to provide internet access. To overcome this limitation, the system could easily be expanded to be deployable anywhere through the use of a satellite phone/modem. However, the use of satellite phones would significantly increase the cost of the project. Since this project was funded by college students and a wifi network was readily accessible on campus, this was not a viable option for our prototype system.
