    Hakko FX-888D

    Cool, thanks - not familiar with Frys. I will do some research and see if there is any regularity to their sales. Thanks again :-)

    Looking for low profile power distribution block

    Not knowing what power will be flowing, would something like this work? http://www.digikey.com/product-detail/en/0391000812/WM15907-ND/894439

    Hakko FX-888D

    Pyro, who did you get your unit from at that price!? Agreed, its very well worth the wait!! I understand the utility of one good tip, but sometimes you may need a specialty, I was thinking of one chisel and maybe one knife edge tip for smd. Curious to hear where you got your unit from :-)

    Hakko FX-888D

    I am looking to buy a soldering station. Does anyone have experience with the Hakko FX-888D? I also have the ability to buy a Weller 51 analog or digital, but I read several recent QC issues with the wellers that have lead me to look elsewhere. Can anyone recommend tips to purchase for general...

    Looking for low profile power distribution block

    Did you ask your boss what exactly he is looking for? Spade terminals under screw terminals are used in the billions - many alarm systems are wired that way. He may have a specific connector in mind. But for low profile, easy access, what you have is a great choice. How many conductors are going...

    Bench Power Supply

    I will look for some less expensive pots, do you think the 300 degree pots will have enough range to easily control the volt setting? The 10 turn are nice, but to sink ~$52 for 4 seems silly to me. Perhaps three of the less expensive in series? This is a 5k one that looks to be of good...

    Bench Power Supply

    Excellent analysis Kris, thank you for weighing in! I don't like the idea of a rotary switch because it forces a set number of voltages, I would rather have a smooth range. I was thinking about removing the switch and associated resistors and replacing with 10 turn pots. I had thought perhaps...

    Bench Power Supply

    I think its time I built a bench power supply to continue my learning of electronics. I have a few thoughts of what I might need, but would like to hear other more experienced voices in this area. I am looking to build not buy a basic psu - and lets not get into the whole linear vs. switching...

    Rapid Prototyping

    Wow, Carlos, very cool! At 3k or more I believe you don't have a market as the existing pcb services are quick and cheap. Don't let that stop you though, if you can develop this further and find an economy of scale to reduce the cost, I think many facilities would love to have something like...

    Designing a Time Delayed Relay

    Thanks for the detailed reply - a substitution in a circuit is a never a simple thing. The entire system needs to be looked at! - a very good lesson :-)

    Designing a Time Delayed Relay

    Awesome explanation, thanks! I see what was missing now :-) To that point, should we devise a way to reduce the voltage regulators input?

    Designing a Time Delayed Relay

    Thanks, I'm trying to learn and monitor details better!! :-) I see the new part - so create a ground plane for the tab and solder the tab to it as the sink. I understand how you came up with 30mA (each Allegro states 13mA for ~26mA total) but lost you on the 600mW calculation. The Allegro...

    ANSI C IDE?

    I have installed them, but haven't had a chance to run through them yet. I expect to have loads of questions soon! I checked out Dave Jones' take on the PIC3 and the equally funny reply from the folks at Microchip - it looks like they fixed some of the issues(LED and decontented material put...

    Designing a Time Delayed Relay

    I was looking at building a bench supply and got to thinking about voltage regulators. Will the current LM78L05 be able to supply enough current to the circuit now that we have expanded and added another sensor and some discretes? I read the datasheet and it indicates a max of 100mA.

    ANSI C IDE?

    sorry about that - wrong thread: As far as programming is concerned: I am having a hard time weeding through the plethora of information on C and C++ For the purposes of understanding and programming PIC's (not saying that I will be able to do it!!) what is the better learning environment...

    ANSI C IDE?

    I gave MS Visual Studios another try because the IDE looked simple and there was pretty good support info on the web.... turns out my main problem was a linking issue caused by the need for a SP1 update to the Studios prog. !!! That'll drive you batty :-( If I hadn't any experience in C++ at...

    ANSI C IDE?

    You guys are awesome! Thanks Kris, I am downloading that and I will check it out :-)

    ANSI C IDE?

    Does anyone have a source for an ANSI C compiler/IDE? I am trying to find a link, but there are an overwhelming amount of entries! I have tried several already, but they are combination C/C++. I am reading K&R's C and would like to compile some of the examples and edit them, but the C/C++ IDE's...

    How do you PROPERLY split a wire into two or three ?

    The standard j-boxes that we have in the states for mains wiring don't have screw terminals. If that is the case in your neck of the woods, a j-box and wire nuts would be the universally accepted professional method. Twist the wires together then twist on the wire nuts. Make sure the j-box you...

    Transient Voltage Suppression - TVS - Silent Knight 3320 16v security/fire system

    David, I had really good luck some years ago tracking down a vishay product that had burnt up through digikey. It was a smd component and the surface was charred, but they were still able to figure out what it was. Try and contact someone at Digikey, this was the person that helped me: Becky...
