Benoit Frigon posted his audio/video routing switcher project: It’s an audio/video (composite) routing switcher, i used it to switch between video sources on my tv. The tv I had back then only had 1 video input. It consist of a 8×8 video crosspoint (MAX4456) and a 16×16 analog crosspoint (AD8113) controlled by a small microcontroller […]
Orlando Cosimo with Creativity/Design blog was experiencing instability problems with the HDMI output on the Raspberry Pi which are typical when using an HDMI to VGA adapter. He devised this solution using three resistors and an LM317 voltage regulator. Orlando states, “This addon hardware extends a past project and it allow to increase the flow […]
jokkebk over at Code and Life has developed a simple “HDMI server” for the Raspberry Pi that uses pyserial to receive commands over Pi’s serial interface, and pygame to display graphics primitives according to those commands. An Arduino client was written to send these commands to the Pi, drawing a string of blue rectangles to […]
We caught up with Mitch from Hackvana in Shenzhen, China. Mitch has spent the last year and a half sourcing parts in the giant Huaqiangbei electronics wholesale market. His goal is to harness the resources in Shenzhen for hardware hackers around the world. Like many hackers, Mitch was annoyed by how much time it takes […]
Shooting in the workshop and away is done with JVC Everios in 1080P. They’re nothing more than a lens and CCD, so OK but the codec is not very good. Recently we’ve been recording the audio with a separate Zoom H1N recoding device, and a cheap Shure lapel mic. Footage and audio tracks are dumped to […]
Proper soldering iron maintenance and soldering techniques required to get a perfect solder joint every time. Via PCBheaven.
Mike made a video on how to speedup SMD assembly. He uses air/vacuum powered tools to for pickup, and placement, as well as for solder paste dispensing. Don’t be put of by thinking of expensive air compressors and vacuum pumps, as he gives some great advice on using inexpensive parts to build your own. Via […]
Here is a collage video of Omaha Maker Group hackerspace projects and activities. The Omaha Maker Group exists to facilitate a place where people can explore Technology, Science and Art. We operate a community workshop in Omaha, Nebraska and have bi-weekly meetings where people can collaborate, share resources, create, and learn together. We are Omaha’s […]
Today is Workshop Video Thursday so we spent a lot of time in filming and editing. We still haven’t found a great solution for the screen capture software. Firmware development took a hit today, as we wasted most of the time following wrong assumptions. While implementing the final “menu activated” function, we somehow broke the […]
R3tikus received the Big box of parts and made a video (in Spanish) showing all of it’s contents. We had lots of stuff hanging around since our move to the new workshop, so we decided to send it around to forum members in the big box of parts. People take stuff out, and replace it […]
As a response to yesterday’s Workshop Video on how we stock our parts, Alvaro made a video of his own storage system. He predominately uses portable boxes, which have 4 removable compartmentalized containers. We also talked with Alvaro at the Bay Area Maker Fair 2012, and his wireless friend finder project. Via Twitter.
Experience the Bay Area Maker Faire from the perspective of a presenter. Veteran Makers talk about their projects, and give advice on preparing for your first Maker Faire. We also take you inside the ‘exclusive’ maker-only pre and post parties. You’ve never seen a Maker Faire video like this. Don’t miss last week’s video with […]
Exapod is building a line following robot based on the dsPIC33 and stuff he won from SparkFun‘s giveaways. Watch the little robot race through Monza in a video below. i’m planning of building a robot with a dspic33fj128mc804 and two encoders for implement some dead reckoning algorithms so for learn something on the dspics i […]
This week we take you on a Global Geek Tour of the electronics markets in Seoul, South Korea. Seoul isn’t known for its markets like Tokyo or Shenzhen, but with electronics giants like Samsung based here there’s a huge and thriving scene. We visit Yongsan, then stop by Hacker Space Seoul before heading into the […]
Here’s another SMD soldering video tutorial. It features the use of 4 different flux types: pen, liquid, gel, and syringe. The video starts with soldering a 0603 chip resistor and moves up to a 208pin 0.5mm pitch QFP IC. Via the comments.
Making workshop videos is a lot of fun, but editing the high-def video is painfully slow on even our best CAD workstation. We set out to upgrade one workstation to run Adobe Premiere with a budget of about 500 bucks. It’s not a killer gaming rig, but it encodes videos in minutes instead of hours: […]
We broke out 4 different types of flux we had in the workshop and tried them with surface mount parts. Liquid flux, flux paste, syringe flux, and a flux marker are all tested. We used each to solder a 0805 resistor and some pins of a QFP 0.5mm pitch IC to an xQFP protoboard. Edsyn […]
This Nixie tube tester has an 11 position switch to change the displayed digits. A simple device for testing and/or healing Nixie tubes of IN-18 type. An 11-pole switch is connected in series with a 50 KΩ pot (+ 470 Ω resistor for safety), powering from an 180V DC source. Normal operation at 2 mA […]
Krash writes to update us on his series of Spy Video Trakr hacks on Instructables. The short video above demonstrates his hack which adds motor control to raise and lower the camera. We also note the laser and missile launcher mod which grafts a USB-powered foam missile launcher, with pan and tilt, and even a […]
Arhi built a transistor tester, a tool that recognizes and measures most common semiconductors. We’ve been following this project closely for the past week or so. After building a perf-board version, he made this version to put in a case. Check out the video of it in operation above. Via the forum.
