CPLD LED blinker based on XAPP078
http://www.customvoyages.com/xc9536
CPLD LED blinker based on XAPP078. I'm working on a board that will exceed the Eagle freeware limitations, so I am experimenting with gEDA. Which includes the schematic capture program gschem. This is a board I made to try out the workflow. Use a very, very slow clock. If your goal is blinking visible to humans, a 1MHz clock requires 20 flops to divide down to 1Hz. A Xilinx XC9536 only has 36 total flops. This board has a 60Hz clock generated by a 555 timer. Beware their confusing schematic—it has ...

Homepage of Stefan Salewski. A footprint generator for the free PCB tool of the gEDA collection. If you have a schematic. Of an electronic device and want to build a real device out of it you usually make a PCB. A printed circuit board. Usually this board is first populated with "footprints" or "land patterns" which are needed for mounting the electronic devices like resistors, transistors, operational amplifiers and so on. The PCB. Program of the gEDA. Collection of free software. Interpreter to do its ...

http://wiki.geda-project.org/geda:faq
What is the gEDA project? What is gEDA/gaf and how does it relate to gEDA? What is the gEDA suite? What makes gEDA so different from other EDA tools? Why does the gEDA Suite seem like a collection of random programs, and not a single integrated application? So which is better, a suite (i.e. confederacy) of programs or an integrated application? Tool XXX is missing critical feature YYY! What can I do? What license does gEDA use? Where can I get more information about and download gEDA? Riends . It is ...

MMA2260 Accelerometer Demo
http://www.customvoyages.com/tippy
This little board demonstrates the capabilities of the MMA2260 /- 1.5g X-Axis Micromachined Accelerometer. As you tip it back and forth, LEDs light up to show the magnitude and direction of the G force. The MMA2260 is the fat SOIC 16 in the upper left, isolated so it could be cut off of the board and used as a breakout, keeping only a pin header and the recommended decoupling and output RC filter. There are several errors in the datasheet that I noticed, and I didn't read it very carefully! Those problem...

Replacing the Brains of a JUMBO UNIVERSAL REMOTE
http://www.customvoyages.com/jumbo_ir
Reprogramming a JUMBO UNIVERSAL REMOTE. I mean ripping out the old control circuitry and replacing it with a programmable microcontroller. If you found this page because you lost the tiny instruction booklet with the super-fine print (an ironic choice for a device with 1" tall buttons! The page you're looking for. You should Buy a Logitech Harmony 670. If you are interested in replicating this project, and your primary goal is to have a nice universal remote, let me strongly. Based rather than device.

Spark-Gap Tesla Coil | Newell Post
http://www.gempillar.com/spark-gap-tesla-coil.html
On 2013-04-17 tags: electronics. To build a spark-gap Tesla Coil for the extra credit assignment of my undergradute Physics class that knocks your socks off. Completed (Socks were knocked off with an A grade in the class :). Here are some videos and photos of my spark-gap Tesla Coil. Physics course we had an extra credit assignment and I decided to build a Tesla Coil. No one helped me with this Tesla Coil but I did get some good advice and information from reading www.pupman.com. 50 MHz and Up.
