    My First Pulse Width Modulator Mod

    I hooked it up and was going to do some tests. I decided to put a 330 ohm resistor in R2 just to see what would happen. It would not power up after that so first thing i did was pull my supply wires and test for voltage. Then next for some odd reason i hooked it back up backwards. Anyways i am...

    Now with a bit of solder mask. Still trying to work out the bugs on it but it is not too bad.

    My First Pulse Width Modulator Mod

    Might have to since when i set up the multiple layouts i somehow opened the old one with the regular zener layout. Other then that i think the board turned out ok. Going to dril a couple holes make sure both sides are lined up.

    Ok i am going to roll with it like is. Circuit looks correct to me also. Might just get it done before the mail lady gets here today. Here is the photo transfer onto the copper clad board. Time to mix up some chemicals now. Here is the etch in progress. You can see the solution turning blue...

    My First Pulse Width Modulator Mod

    here is the chip side. Not sure what you want to do about the power carring neg output. It is close to the edge and fat but it really need to be on the big side for the amps that are going to be going threw it. I guess i could cut it down a bit and get a small positive boarder going up there...

    Hows this for the switch side I will make up a foot print with the long pads for the zener. Edit: Zener pad

    My First Pulse Width Modulator Mod

    I dont have a rms. I did a duty cycle on it and also a amp test. It will go from full amps to Zero with the 10k pot and a duty cycle from 100% to 10%. I will throw my 250ohm back on the breadboard and see what i get. post some results in a bit

    My First Pulse Width Modulator Mod

    No this has nothing to do with it. It is this things fault. After taking a closer look the inducter would have been point oposite of the way i thought it was. Might not think it would make a difference but space i had planned for is really tight prevents me from getting a needed wire in a...

    My First Pulse Width Modulator Mod

    Ok delayed once again. The layout for my board had a problem. It wouldnt have worked out so well if i couldnt get the atomizer power wire soldered in. I believe I finally have a solution worked out that doesnt require me making the board bigger actually might be able to shave another .100' of...

    My First Pulse Width Modulator Mod

    I had a problem last night , thunderstorm rolled threw took out the power for a few hours. By the time it came back on i had enough beer in me to know better then to drink and CAD. Getting close to flipping the board and doing the other side. Other side will be easy, it is mainly my board...

    Anyone Interested VV PT

    Here is my PT that i hook to a variable card just like the one 5 card has in the box. Ego coneable Ego tankable It can also be used for self defence by whipping it around by the cord and smacking people in the head with it. The best part is that the chicks dig it. Ok i might...

    My First Pulse Width Modulator Mod

    Ok check this out I had to redo it on my layout i could not get this thing to merge the two. I fattened everything up as much as i could and moved it towards the middle.

    My First Pulse Width Modulator Mod

    Oh man i am too damn ugly not to get my beauty sleep. But on the serious side i dont sleep all that much these days so there is a good chance I will get it done. That is if i can quit posting in the forums and get back to work.:vapor::2cool:

    My First Pulse Width Modulator Mod

    Not a problem at all. I might just get 9 of these with the space i have left on the board. Not sure they are going to want to start off with 0603 resistors they going to be tough for a beginner. Had to go work on a computer so i am behind schedule now. Still might get it done tonight depending...

    Where to get PCB's made

    Thanks , Yeah I tend to Old school engineer things. Like this passthrough I made out of some solid aluminum stock. If someone broke in the house to rob me i could use it like half a numb chuck Smack them in the head with it till they got knocked the hell out. Even after that...

    charging batteries in parallel

    If you use protected batteries i am pretty sure it wont blow up on you and there wouldn't be a need for diodes.

    My First Pulse Width Modulator Mod

    Just got done slapping a switch on the breadboard. I had no problems with the mosfet staying clamped. I`ll leave that 0603 pad there anyways just in case. What size tube is that you plan on using wall thickness that is. I think 1/16" might be as big as you can go. 1/8 on both sides would take...

    Cool linux has come a long way in the last 10 years. Let me know if you need any help, there is also a few tutorials on youtube for geda that might be worth watching. Yeah you can never under estimate the determination of workers to find ways to surf porn at work and then you get at least a...
