    Beginner Project

    First off welcome to the forum. I would suggest you start out with a simple kit that includes a printed circuit board. That way you can get an idea what the parts look like.

    Chicken/Egg Question

    1st. off I'm a newb. with microcontrollers. I've got a Parallax Basic Stamp that I literally blew the dust off of. I was experimenting with turning on and off LEDs and found out that 2 ports were bad. I then found out that the processor in a BS2 is a PIC 16F57. The chip is relatively cheap but...

    Semi Newb Advice Request

    The one using a PIC18F4620 : http://hypnocube.com/products/4cube/4cube/ And one using a PIC18F2550 : http://www.2dkits.com/zencart/index.php?main_page=product_info&products_id=28 They seem a bit pricey but alot of the brain work has been done.

    Semi Newb Advice Request

    For now I think to make things easy on me I'll get a kit. I found one that uses a PIC18F4620. Then a development kit afterwards.

    Semi Newb Advice Request

    I'm pretty much thinking of a uC that's in a DIP and inexpensive . I'm not stuck on Arduino especially if it's expensive.

    Semi Newb Advice Request

    I am about to ask for a B'Day gift. I am thinking of getting into Aurdino/PIC controlled things. I want to program a main chip and plug it into the device in question using a minimum amount of 'through hole' parts. 1st. project: the infamous 4X4 RGB Cube.

    Help with reading schematic

    We've all been noobs at one point. The more you learn the more you realize how much you don't know. Back in the day I had the advantage of a couple of real electronics stores as well as a Heathkit outlet to quench my thirst. I would suggest a kit that includes everything (components, case and...

    Simple Analog Delay Circuit

    You might want to consider a PT2399 (Princeton Technologies). It uses minimal external components, has 2 controls and by tweaking the pot values you might get up to 1 second delay. They make other models but I am familiar with this one.

    Transistor Identification

    I vote for the Toshiba transistor. http://www.datasheet4u.net/datasheet/2/S/D/2SD549_Toshiba.pdf.html Being a scavenger of electro-junk I see manufactures drop the 2S part of the designation all the time.

    Blown capacitor in power supply

    Get a new PSU. Harvest the heatsinks, fan, bridge, socket and thermister for future use. That way it wont be a total loss. By the way it looks like the toroid next to the bad cap got pretty hot.

    Safety Tips for the Complete Idiot

    On a similar note let me relate an experience. When I was first dating my wife she gave me a crucifix and rosary. Eh whatever. So I put it on my rear view mirror. I owned an Alfa Romeo convertible at the time.. Some time later there appeared smoke and a red hot rosary. Not a good omen. Turns...
