I was looking for a tripod mount for my iPhone and actually found a pretty neat little contraption by Square Jellyfish.  The name is a big silly, but the product is solid.  At $15, it’s a must have item for the accessory bag.  Great for taking photos or video, even works for handsfree FaceTime.   Watch the video for the details on how it works.

Available from Square Jellyfish Tripod Mount

Programmable DC Electronic Load Tester (Array 3710A/ProTek L-300)

As many of you know I’ve been busy finishing my latest hardware creation, Myro:Air and as part of a certification process, the USB port on the back of the unit must be able to provide a stable 5V at both 1A and 2.1A loads.  Long story short, it’s been quite the process to test the power supply consistently until I found this nice Programmable DC Electronic Load system.  It’s marketed under many different brands like TekPower, Circuit Specialists & ProTek but it usually also contains the model number of 3710A and is made by Array.  The best part is the price — $349 for the 360VDC/150W and $499 for the 360V/ 300W version.

I purchased the unit from Circuit Specialists and will post a full video review soon.  It’s allowed me to easily test different component profiles as well as test the required overload protection of Myro:Air’s USB circuit.    The unit also features a built in multimeter that can also measure the voltage of the circuit under load though I still prefer to use my DMM for more accurate measures.   I’ll also demonstrate the PC software it ships with in the video.

Feel free to post an questions in the comments and I can answer then in the video.

Saleae Logic16 – Logic Analyzer

saleae logic16I purchased the Saleae Logic16 a few months back to “sniff” a SPI bus and since then I keep on using it as my default Logic Analyzer — that’s when you know it’s money well spent.   Saleae offers two models — a 8 channel ($149) and a 16 channel ($299).  I went for the 16 channel version because it offers a bit more bandwidth (sample 2 channels at 100MHz, 4 channels at 50MHz, 8 channels at 25MHz, or all 16 channels).

The hardware is solid and well made and ships with everything you need — a nice hard case, USB cable and color coded wiring harness with micro-hook probes.  The best part, however, is the software — I use a MacBook Pro (also running WindowsXP via VMWare)  with 16gb ram and it’s always better to run native apps as much as possible but most companies don’t provide native apps for OSX, hence VMWare.  Saleae actually offers ports of their software that runs on all major platforms (Windows, OSX, Linux).  The software offers almost endless sample captures but the most useful feature is the protocol analyzer.  It currently supports I2C, Async Serial, SPI, 1-Wire, CAN, I2S, PCM, UNI/O, Manchester, and MP Mode — making it easier to see the decoded results along with the waveform   So far I have used I2C, SPI, I2S/PCM and Async Serial with it working flawlessly.

Highly recommended!
