    Will my circuit work? (trying to make a who pressed first quiz buzzer)

    Interesting design Adam. Do you intend to tie the reset from the other IC together so that they both reset at the same time?

    Different power supply or just throw in a voltage regulator?

    I am not sure what the probability is, just mentioned it since the risk of injury could be great - regardless of what the chances are. Don't get me wrong, I like cool projects that repurpose items instead of trashing them, but why not use wire and battery for igniting?

    Different power supply or just throw in a voltage regulator?

    Have you any concerns with stray wavelengths that could be received, possibly igniting your fuse prematurely?

    Anyone recognise this component?

    It's a good thing Dave can read dot matrix ;-)

    EP Newsletter

    That's part of the problem of anonymity on the web sometimes... don't know if members are alive or not! We had this happen on one of the woodworking forums, luckily enough, some of the members were friends offline, had had gatherings in the past and had called the spouse to find out the bad news....

    I actually was on here back then and he had helped me. He was very resourceful. I was under a different screen name at the time. I guess we all come and go. Thanks for the input Dave, appreciate it ;-)

    On another note of AFK members: does anyone remember Resqueline? Does anyone know what happened to him/her?

    EP Newsletter

    Indeed, gone since 2/27 with no word. I did ask a few folks on the forum, but they haven't seen him either. I even checked the obits! I hope all is well with him and his family. Edit: I sent him an email as well.

    EP Newsletter

    Did anyone else receive the newsletter? I think its a great idea, especially for folks that don't frequent the site that often. A nice aggregation of posts. Of course, I am biased as I was top billed :oops: . Hey, even a broken clock is right twice a day :D

    Designing a Time Delayed Relay

    Delving into MPLAB X a little bit today, I was able to burn a program onto a pic as a test. MPLAB's interface leaves something to be desired... I had to find a cryptic setting to allow me to load the program onto the chip since the circuit was not powered. One would think that most developers...

    Tips for learning recursion?

    Nope, I am still interested ;-) Can you expand on this a bit? I am a novice and I can see the idea that you present, but I can't quite grasp the implementation. Specifically, can you give me a snippet of code (c is fine) that I can insert and try out?

    Help Getting Started with PIC Microcontrollers

    I am waiting for my "I'm with stupid" shirt to arrive... I can't even get an IDE to function properly! I am currently reading K.N. King's "C Programming - A Modern Approach" but have been eyeing FlowCode as well Chris, LOL Interesting find!! - - > http://www.tutorialspoint.com/codingground.htm...

    Toner transfer for PCBs having BGA packages on them

    I have had good initial results with etching a board with hydrogen peroxide and muriatic acid. I think these chems would work far better for your thicker platings. Have you ever given them a try? Cheap and probably more environmentally friendly than the ferric chloride. The muriatic acid is...

    Microcontroller controlled by pushbutton for LED flashlight

    TT, the group here has an amazing background and talent set. The reason they ask for the project in its entirety is because they can look at the project in unique and creative ways that you can't imagine. I don't exaggerate, the skill set is truly humbling... Retain some information that makes...

    Toner transfer for PCBs having BGA packages on them

    Yes, I had read quite a bit about the Brother units not being useful for our purposes. I wonder why they use toner that is not refusable? I would think that to have that characteristic would be more expensive than what the competitors are using. I wonder if it was necessary for their fuser temp...

    Toner transfer for PCBs having BGA packages on them

    Nice work @(*steve*) ! I had toyed with the idea of getting a laser printer, we too have some low expense options from local office supply stores. I haven't seen any with 1200dpi. Have you found that to be the ideal coverage or does it still need a higher dpi? Has playing with the darkness...

    PIC emulator software

    Hi Chris, I was doing some reading on Microchip's site and came across their own training which is now self paced. I thought it was pretty cool. The coverage of the IDE is pretty good, they assume nothing so they go over the buttons, which is nice for a quick familiarity of the program. Here is...

    Microcontroller controlled by pushbutton for LED flashlight

    Good snag! The software that comes with it though may be old and you will want to download the newest from the website. Good luck with it and keep us posted on the project.

    Microcontroller controlled by pushbutton for LED flashlight

    "my sympathies friend, you have no manner of luck at all" - prisoner from Pirates of the Carribean (1st) All kidding aside, they don't ship until monday anyways, so if you call and order first thing there won't be a delay. If you want to order now, I checked sparkfun's website and with UPS...

    Microcontroller controlled by pushbutton for LED flashlight

    That is a tough break... especially when shipping is already accounted for. I don't know what time frame you have for the project. I am a hobbyist, therefore my project time horizon is long... possibly longer than most would have patience for. If you can wait, the E-bay stores of the original...
