    Microcontroller controlled by pushbutton for LED flashlight

    Your right. I didnt notice the missing trace. I am using Dip Trace and have noticed nets being deleted when you move components, thats not very good. Maybe @Supercap2F has seen this and can help. Else I will email them. Cheers Adam

    Microcontroller controlled by pushbutton for LED flashlight

    Hi Hop I guessed you knew about floating ports, I wasn't trying to teach granny to suck eggs, apologies. I made a mistake on the pinouts yes sorry. It was late over here, no excuse though. The latest circuit has righted that so yes we need to change the code. Adam

    Microcontroller controlled by pushbutton for LED flashlight

    Hi Hop A floating port pin is not good for any micro. If not pulled up or down noise on the input can cause the pin to oscillate or be in an indeterminate state increasing PCB current. But if you set the pin to an output and high or low dependant on the design this will also work fine. I choose...

    Microcontroller controlled by pushbutton for LED flashlight

    Hi Hop Been thinking about the option for jumping back to where you left off after sleep. Maybe an easier approach would be just to put a label after the sleep command you can then goto after you have checked the WDT bits. Another problem you have is that with two sleep commands one at the start...

    Microcontroller controlled by pushbutton for LED flashlight

    Been working on a new PCB, using a new package so bit of a learning curve. I have designed it with the original PIC but it can be changed to another PIC if we can't get the 10F200 to work properly I have added a power connector also and the spare pin 2 for J1 I just connected to VDD. Would...

    Hello

    Hi Fisher welcome to EP. What interests do you have in electronics? Adam

    Can anyone identify this transistor?

    Love the pictures. If you do this it is advisable to take ESD precautions so you don't damage the transistor from any ESD events. Adam

    Difference between dimmable and non-dimmable LED downlighters

    Hi Dimmable LEDs have a special driver inside to allow them to be used with dimmers which probably accounts for the extra cost or the fact that they just don't sell as many. The other thing you need to watch out for is some of the old dimmers might not work correctly because they often need a...

    Microcontroller controlled by pushbutton for LED flashlight

    Hi Hop Yes I like my PICO-SCOPE also. It's the basic 2206A and does have a arbitrary waveform generator that I haven't used yet. "Is Figure 4 the supply running with the 100 μF capacitor? That's mighty small ripple!" Yes correct. "The supply drop when the switch is pressed is humongous. Is...

    Need Some Help Finding the Right MOSFET

    No probs mate. Just be careful Dan, please! Adam

    Microcontroller controlled by pushbutton for LED flashlight

    Hi Bob The switch could be pressed for 500 ms so it's only this initial time during mode setting which would be the issue. Cheers Adam

    Need Some Help Finding the Right MOSFET

    Might be best to check with them first, the reviews down the bottom don't give them a good rating for discharge current. They do say you can connect them together to form a bigger pack. But my personal choice would be a qualified pack with leads and a connector. Adam

    Not sure Dan to be honest. Adam

    Need Some Help Finding the Right MOSFET

    Yeah no probs it was an example to show you what's out their. Check with your local hobby shop. Adam

    Bench Power Supply

    Directional arrows like on Transistors and Diodes perhaps!

    Need Some Help Finding the Right MOSFET

    Yes it will have inside the pack. Any batteries that have a set of wires and or connector when sold must be qualified. It's the law over here. Adam

    ID this capacitor

    Hello It's not a capacitor it's a varistor for surge suppression. Thanks Adam

    Ok so you might need a different battery. Have you looked at model RC batteries? Adam

    Here is an 800 mA one. I couldn't find a 1 Amp version, I think the next size up is 1300. Adam http://www.batteryspace.com/custom-polymer-li-ion-battery-3-7v-800mah-2-96wh-with-open-end-wire---un-approved-ndgr.aspx
