    No need for razor blades. Just use APC electric props. They are pretty near razor sharp at the tips to begin with. Given what one will due to a finger, I doubt a balloon would stand a chance.

    You can make your own. Check out Pilkington Mirrorview and Mirrowpane. You can also get acrylic two way mirrors that are cheaper though harder to make look good at large sizes. Put LCD panels on the back side and their you go.

    First thing I went to find out was “how much for the clock?” sigh $500 is well outside the range for an impulse buy, but I would love one. Although, ½ meter might be a better size.

    Just a note. Your Fritizing diagram is missing the ground connection between the PCA9306 and the pro mini.

    I’m of a couple of minds here. Anything that get people (kids or adults) interesting in programming and electronics is good in my opinion. Anything that makes it easier for someone to implement an idea they have for a widget, piece of interactive art, automatic cat herder, or whatever you have cooked up is also good. Things like visual programming and arduino certainly facilitate interactive art and such things and open up the world of custom algorithm implementation to none programmers. It does not make you a programmer. Actually, I consider a programmer to be a step below in the talent spectrum. All you need to do to “program” is learn the language syntax, whatever the language. Visual programming focusing on algorithms or program function.

    My big beef with visual languages, and even the move to higher and higher level languages is that it makes it easy to accomplish things in a bad way and so we end up with multi-ghz processors being needed to flash a few LEDs. I’m thinking of the penchant for using Raspberry Pi’s in place of arduinos because you can run in a normal Linux OS environment. That’s fine for some hobbyist at home, but it works its way into the commercial environment and suddenly your toaster has to run embedded linux so a two bit java developer can write the code that lets your burn your bagel in the morning….

    I need a US source for a replacement cable. Apparently the cable strongly resembles a cat toy as I found mine, with camera attached in our laundry room when I got home. There are holes punched completely through the cable. Any suggestions?

  • News - So You Want to Learn FPGA… | about 10 months ago

    Yep, FGPA’s are hard. You are working at the absolute lowest level of computing hardware possible. It is equivalent to connecting 74LSxx parts with jumper wires on a bread board. Add to that the fact that timing matters immensely and you have a complex, and difficult to learn environment. Learn async digital logic. Learn synchronous digital logic. Work your way up the ladder. When you understand why most FOR loops in Verilog cannot be synthesized, then start more complex stuff. Sometimes concepts are hard for a reason and not everybody gets them. That’s ok. Sometimes, something that looks cool takes a lot of work, maybe more work than you want to put into it. That’s ok too. In reality, if you are looking for high level programming constructs to put down large blocks of functionality on an FPGA, you don’t don’t need and FPGA. You need a microcontroller.

    It won’t let me input more than a line of text… sigh. Swap either the sizes or the types.

    “Check the compile size: 2458 bytes for int versus 2488 bytes for byte. Not a lot bigger, but it IS bigger.” – No, it’s not: 2458

No public wish lists :(
