    My First Pulse Width Modulator Mod

    I was hoping to etch tomorrow . I have been switching back and forth between this board and mine. I still got a bit of work to do on mine. I got some liquid Tin coming in Wednesday So no sense in getting it done before then. Oh yeah i have some pre tinned wire i use for threw hole vias i will...

    My First Pulse Width Modulator Mod

    Not sure if i under stood you correctly but here is what i changed. For the led i think i would go with a tact switch with a built in LED , they are taller i believe but it might work out for the better. Edit: Or maybe something more like this , not sure what edge your going to be clamping...

    My First Pulse Width Modulator Mod

    Here is a quick rework not polished yet. I could move the pot to the green line if needed. Let me know what you think bstedh

    My First Pulse Width Modulator Mod

    Shouldn't be a problem going to have to rework it a bit anyways the diode and resistor are going to be hitting the pot now. going to have to go with that smaller diode the 0603 to make things easyer. Is the pot ok or do you need more clearance ?? I might have enough room to bring it back another...

    My First Pulse Width Modulator Mod

    I flipped the pot around that will give you a .100 clearance from the end of the board i slapped a green line on it. Nor sure what you mean about the fet. If you can download this image and load it up in paint of something and show me where it needs to be.

    My First Pulse Width Modulator Mod

    Ok i added a 0603 resistor off of pin 3 in case there is a latching problem you can tie it to the low side. I went ahead and made a foorprint for the Ti 555 chip from scratch. It now shows the body of the chip the legs will hit about half way down on the visible pads. going to wait to hear back...

    Pot can be moved for sure there is quite a bit of room to play with. Also need to know what side of the board you want it on. I just guessed and though it would go opposite side of the switch. Just need to know that and how much clearance you from the end it needs. That foot print for a...

    Where to get PCB's made

    If you give your traces .100" per amp you overkill more then me. One inch traces for a 10amp reg. I guess you meant .010" . I use this tool that lets you know how much your traces will heat up under load. I try to get them to heat up less then 10cANSI PCB Track Width Calculator Took out the...

    Ok how do these two look to you bstedh. You didnt have a LED part in the list so i just slapped a 0805 pad in there. can change it out if needed.

    Where to get PCB's made

    Here is what i got for the top of the board. Was able to cut the vias down to two. Also almost shaved 100 thousandths off the 1/2 width if you wanted to the board can be thinner. EDIT: Here goes the bottom. The blue trace is a suggestion to pop it back threw on the front and power pin 4 and...

    Where to get PCB's made

    I use a 24 gauge pre tinned solid wire and solder it into the board for signal. If i have something thats going to be running some amps threw it I use a 18 gauge solid copper wire tin it and solder it in the board. A bit time consuming but it works. I guess a lot of folks wouldn't go to all this...

    Has anyone thought of this?

    Seen quite a few people post up in here about building one or wanting to build one. As far as i know no one has done it yet. I think it would be pretty easy to do using a old bread toaster and 220 volts:vapor::blink:

    Where to get PCB's made

    Thanks Craig , Yeah i am pretty happy with how the boards come out. Even have the solder mask going now got most of the bugs worked out of that. Now if i can only get my mod finished one of these days. Doing a total rework right now found a few parts that are going to...

    ******* 3 10 296-6502-1-ND IC OSC MONO TIMING 500KHZ 8-SOP ***** Pretty sure your layout is using a 8-SOIC (0.154", 3.90mm Width) not the 8-SOIC (0.209", 5.30mm Width) which is a wider chip. The Digikey part # for the 8-SOIC (0.154", 3.90mm Width) is 296-16792-ND...

    Ultrafire TRC 3800mAh 18650

    Fake or not the mah rating is a lie. No one makes a 3800mah 18650 battery. The highest i know of is the Panasonic 3100mah and really the only reason they get that is by having a lower shut off voltage.

    Where to get PCB's made

    No secret really I use h202 and muratic acid to etch with. It is slower but works well. other then that some good photo paper helps the stuff I use, I get 100% transfer with. Trick to double sided boards is have a small via in two of the corners across for each other. Print your layout on...

    Easy OKR-T VV mod

    Wiper should be going to pin 5 , Pin 1 should be let open/ or not used. Sounds like you got it set up backwards. I doubt all 4 regs are bad
