Like many others we have succumbed to the urge for a cheap laser cutter. What started as a $200 purchase quickly doubled, but that’s still a fraction of the cost of an expensive one. Why do we what it? That’s a not very well hit secret. The ubiquitous blue Chinese freight truck drops the crate […]
Today we piled into a taxi with visiting hackers to check out two electronics markets. Both are about an hour north of Shenzhen in Shajin, a very industrial area. We have high hopes of finding more equipment and tools than are available in huaqiangbei. Top on our list was a USB controlled wire cutter Zach […]
Cruising through Bao’on on way to Shajin tools and equipment market. I’ve never been to this one, but Oomlout and Zach Hoeken both says there’s tons of great stuff. We are looking for a wire cutter and stripped machine, as well as a small laser cutter for blasting polyimide. You can probably guess what the […]
Replacing a NIC with something hopefully high quality from Intel. Noticed that Intel uses a healthy mix of 0402, 0603, and 0805 components. Especially capacitors. Not sure if this is due to cost vs capacity, or if smaller, harder to place components are used sparingly as needed. From experience typical caps get cheaper as they […]
EmbeddedCreations writes: I’ve been working on a new version of the SmartMatrix Shield, not meant to replace it, but to be an option for those that want to maximize the capabilities of the Teensy, while connecting to a matrix display. Let’s call it the SmartMatrix Shield Pro. This board will have the advantage of pinout/functionality, […]
The entire Pearl River Delta area of China is a manufacturing powerhouse. Huaqiangbei, the famous giant electronics market, is just a tiny facet of a huge industrial ecosystem. About 30 minutes north of Shenzhen there’s a giant market the size of a town that supplies not just electronics, but chemicals, materials, tools, machines, and, of […]
Joined a friend on a factory audit today totally unrelated to anything electronic. Spotted a few cool thongs though. This is a metal polishing station with a red bull can full of polish. Down the hall is an unrelated factory making plastic tubing for bag machines. ABS plastic pellets go in the hopper and tube […]
Took a taxi about an hour to the manufacturing area of Shenzhen, Bao’on. When we got in it seemed like there was something wrong with the car or driver, 3rd and 4th gears seemed nonexistent. Initially I though maybe we should swap cabs, its a long trip after all. But that seemed just too paranoid. […]
Shenzhen wasn’t a town 30 years ago, it was barely a village. Almost nobody is from Shenzhen, people come here to make money and send it to family in other parts of China. Over the Chinese New Year, that two week period when you can’t order from Seeed Studio, tons of eBay vendors, and all […]
Prototype Bus Pirate probe cables with heat shrink labels arrived today. We sent professionally printed heat shrink tubes to the cable people (white) and they attached them to 100 cables. We printed our own shrink labels on the L-Mark LK320P and attached them to 100 cables in-house (yellow). Results and cable giveaway below!
We designed a microcontroller board for a power supply, but somehow we forgot to add the oscillator to the circuit. We thought it was enough to add two nets called ‘OSC1’ and ‘OSC2’ to the schematic… Why can’t Eagle cope with that automatically?! The lovely photo was taken with an A5000, and Android-based clone of […]
Shenzhen isn’t just about building electronic hardware, so many things can be created and customized inexpensively. One day we spotted an entire street of shops selling customized signs in Dongmen, the old market neighborhood. There’s a few dozen shops with hundreds of sample signs in different styles hung on the walls, most decorated with binky […]
We had 1000 boxes and part holding trays made up for the new OOMP part management system. These won’t be at Seeed yet, just for our internal use and giveaways, but I wanted to share the result. Each set (box+tray) is about 1.2RMB ($0.20), took about a week to make and deliver. We asked for […]
Here the open source GNU Radio companion program is used to demonstrate the transmission of data from one laptop to another using frequency shift keying (FSK). They use an audio carrier frequency of 23 kHz. You can download the code for the GNU Radio companion flowgraph at Anfractuosity.com.
Makers express their inner geek in all mediums. This collection of crochet sea creatures is amazing, beautiful, and delightfully creepy at the same time. More fun stuff below the fold.
Maker Faire isn’t just a place to see cool projects, you get to try things out yourself. At this pan flute workshop straws, cardboard, and rubber bands are combined into a simple DIY musical instrument.
Tokyo’s extensive metro and train system recreated in colored water and air bubbles by Takatsugu Kuriyama. The colors are the same used on the system map. Tubes rise above and dip below a clear sheet representing above and below ground trains. More cool stuff below the break.
Z-Machines, a robot rock band, headlined the Maker Faire with several concerts each day. These weren’t the only rock stars though, head below the fold to see more noise makers from Japan.
Walking, flying, or rolling, Maker Faire is overrun by bots of all types. A-L-C is an animatronic troll with amazing realistic facial movements.
Arduino, Raspberry Pi, Beagle Bone, whatever – we love the gadgets and electronics designs on display at Maker Faire. @Nasupl_r’s Twitter Mention/Favorite Notify Helmet flashes to life when she’s mentioned on Twitter. An mBed board monitors her Twitter feed, while a Bluetooth connection makes it completely wireless.
