  • Interesting- this may be the first license I have seen requiring “non-commercial, non-industrial, non-academic purposes”.

  • Most common languages like C/C++, Verilog, VHDL are broadly supported standards you can use anywhere. How does Lucid work, does the Mojo IDE translate it to Verilog, then send it to the Xilinx tool? If I spend some time to learn Lucid, is it going to be a portable skill, or does this only work with one FPGA dev board from one vendor?

  • I have one of the Teensy LC beta boards, it works nicely and is of course, cheaper than the Teensy 3.1 if you don’t need the few extra capabilities of its bigger brother.

  • The advert in my email said “allows absolute distance to be measured independent of target reflectance. It can measure off just about any material”. Here, it says it bounces IR light off the target and measures time of flight. OK, but how is that independent of target reflectance? If the target reflects too little light, then you have too little signal, it is dependent on materials with enough reflectance to measure.

  • I have one of these, and sure enough it works. Be careful when connecting it to get it the right way around! There is no obvious mark to indicate which way it connects, and the headers are symmetrical so it fits over the Teensy 3/3.1 as easily backwards as it dos the correct way. The microSD card slot should be facing the opposite way as the Teensy USB connector. This is correctly shown in the Sparkfun breadboard photo.

  • rovingnetworks.com no longer exists, after acquisition by Microchip. Anyone know; does the dev kit still exist? EDIT: I see RN-ISP. http://www.microchip.com/DevelopmentTools/ProductDetails.aspx?PartNO=RN-ISP but not the RN-SDK-G2 mentioned in http://www.microchip.com/stellent/groups/sitecomm_sg/documents/devicedoc/jp557986.pdf (which mentions GCC and Gaisler LEON BCC toolchain).

  • Just FWIW, Skytrak is putting out a new GPS module with Venus 822 chipset, check out NavSpark on indeigogo. Not clear if it will reach its funding goal though. EDIT: looks like it will happen. Maybe SparkFun can carry this one too.

  • This is a very nice board, I have two of them (although not obtained via SF). It is as easy to use as the less-powerful ATmega-based Arduino boards, and super small as well. If you’re buying one of these, you should probably check out the support forum on PJRC, it is active and questions are addressed quickly.

  • I really like my R-Pi, I ordered a second one but that may be months off yet. Meanwhile I got an “Olinuxino-Micro” (ARMv5, 64 MB, SD card, 1 USB) which is like a cheaper, less-capable Pi, but has many more I/O pins, and it is actually available for sale now. The O-Micro software is still very much a work-in-progress though (OE-Debian and Arch-Linux builds exist, but eg. no USB-WiFi adapter support yet). And Olimex has many distributors, SparkFun might even carry it, if they don’t mind the software-sinkhole :-)

  • By the way, my sample of this device cannot provide 500 mA at 5 V as the label indicates. With a 10 ohm load (500 mA / 5V) the voltage droops to about 2.5 V with large oscillations.

No public wish lists :(
