Instructables - Make, How To, and DIY DIY « Filippa Malmegard The Internet of Skills I just watched the refreshing TED group talk on the notion of an Interspecies Internet featuring a hero of mine, Neil Gerschenfeld of MIT’s Center of Bits & Atoms, alongside animal cognition expert Diana Reiss, brilliant network guru and evangelist Vint Cerf and the more unlikely “geek band” member musician Peter Gabriel. Loved the idea […] My visit to ‘NYC Resistor’ – Cult hackspace in Brooklyn On my trip over to NYC this Feb I popped by cult Hackspace / Makerspace NYC Resistor in downtown Brooklyn. I’d met resident hackers Astrida & Kim at Maker Faire in September but not had chance to stop by the space. Hacks gone viral – From my kitchen to 2000+ shares on Facebook One of the most popular “scrap hacks” i’ve posted onto ScrapHacker is the pallet kitchen sofa. D.I.Y’ers = The new innovators ScrapHacker guest post on Wired Design ScrapHacker gets featured in Cosmopolitan Slovenija The results are in!

Connect an iPhone, iPad, or iPod touch to Arduino with the Redpark Serial Cable Step #1: Wire up the RS232 adapter to the Arduino PrevNext Connect the RS232 adapter's power and ground to the Arduino's 5V and GND pins, respectively.Connect the RS232 adapter's TX to the Arduino's RX, and the RS232 adapter's RX to the Arduino's TX. Step #2: Make sure you're set up for iOS development To develop apps for the iPhone, iPad, or iPod touch, you'll need to register as an iOS developer. Although you can register for free, all that gets you is the development tools. Step #3: Make sure you can run an app on your iOS device If you've never programmed for the iPhone before, you can't count on this guide to help you. Step #5: Add a switch to your app On the left pane of the screen, expand your project, and open the folder HelloArduino.Next, locate the HelloArduinoViewController.xib and click on it. Step #8: Import the iOS Accessory Framework Next, you need to import Apple\'s Accessory Framework. Step #9: Add some declarations to the view controller Step #13: Test the Arduino
Système canadien de référence spatiale - Calcul inverse géodésique Démonstration en ligne News: CGVD2013 is now available! Natural Resources Canada has released the Canadian Geodetic Vertical Datum of 2013 (CGVD2013), which is now the new reference standard for heights across Canada. This new height reference system is replacing the Canadian Geodetic Vertical Datum of 1928 (CGVD28), which was adopted officially by an Order in Council in 1935. Geodetic reference systems stem from the need to provide a consistent and integrated reference surface for data analysis. This site provides end-users with the geodetic data and tools they need for a range of commercial and private uses. Date modified:
Wisdom of the Hands Serial Cable - Redpack These Redpark serial cables connect 30-pin iOS devices to RS-232 serial devices. Two version of the cable are available. See the FAQ for details on the differences between the two versions. The cables are used in conjunction with the Redpark Serial Cable SDK.

Q: What kinds of devices have serial ports these days? Q: Which iOS devices are these cables designed for? Q: Is there a way to connect to devices using TTL (logc level)? Q: Can I power the iOS device using this cable? Q: Can I power the serial device using this cable? Q: What apps does this cable work with? Q: Does the cable work with apps available at the App Store? Q: How can I tell if my iOS device recognizes the cable? Q: How do I know what version of firmware the cable is using?
Weller Magnastat Autopsy and Repair » Code and Life Immediately after soldering together my USB password thingy, my solder iron, the family heirloom Weller Magnastat stopped working. Some investigation showed that the base station was providing 24V AC voltage just fine, so I decided to unassemble the handpiece to see if something could be done. Here’s what I found: It turned out my iron was salvageable; read on to learn a bit about the Magnastat and how I was able to repair mine. Magnastat basics The construction of the device is surprisingly simple (see this image): The first (blue) wire from A/C power unit goes straight to the heating element (first red wire with black tube around it). A long tube goes “out” the handle part into the iron tip, and the tip is placed at the head. Note that in my model the tip and the magnastat are one solid piece (magnastat is in the base of the tip), newer models have a separate magnastat and tip, and you can change the target temperature just by changing the magnastat part.

How much material does the laser burn away? In 2008 I sought to try and quantify the kerf of our laser cutter, or how much material the laser cutter burns away when cutting specific materials. The idea behind providing this information is so you can make a more educated guess of what sizes to draw your shapes if you are needing a tolerance fit. This information is particularly relevant if you are creating inlays and slotting joints*. Please note that these are old figures, which we are hoping to update soon – we cannot guarantee super-precise kerf widths at this time. Prototyping for yourself is the best way to guarantee the perfect result but hopefully this info will give you an idea of what to expect. So anyway here are the results… For those using imperial: And for those on the metric system: So what does that mean? If you were to draw some parts to be cut from 3mm acrylic as dimensioned below, the white square on the right would end up at 39.80mm and the hole in the middle of the red square would be 40.20mm.
MaKey MaKey: An Invention Kit for Everyone (Official Site) List of single-board computers One of the first 10 MMD-1s, a prototype unit, produced by E&L Instruments in 1976. The "dyna-micro"/"MMD-1" was the world's first true single board computer. The MMD-1 had all components on a single printed circuit board, including memory, I/O, user input device, and a display. Nothing external to the single board except power was required to both program and run the MMD-1. The original design of the MMD-1 was called the "dyna-micro", but it was soon re-branded as the "MMD-1" List of single-board computers – computers built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer.

Tutorial ~ Hanging Fabric Baskets Or Pockets I know I say this every time, but I am so excited about this project! The possibilities are endless! And they are so easy – I am going to have baskets hanging all around my house in a weeks time. I am using these above my sewing desk to hold all my notions and patterns. First I will show you how to make them, then I will tell you all the ways I think you could use them…then you can tell me all the ways I never thought of! Here is the tutorial for making larger baskets with plexiglass in the bottom for great wall storage. Supplies: Fabric – how much you need depends on how big and how many you make, we’ll go over thisHeavy weight interface lining – you want it stiff enough to hold its shapeAll your sewing stuffCurtain rod or wooden dowel with brackets to hang it on Cutting out fabric: To make one basket you need two pieces identical in size. So you have two pieces of fabric the same size right? Now you should have two pieces the same size with interfacing ironed on. Your done!
