12oclocker Posted February 15, 2009 Author Report Share Posted February 15, 2009 (edited) 12- i like the staircase lights w. touch buttonthanks,here is an update of my battery charger build process........before etch...after toner transfered...after etch, final PCB before drilling the holes and mounting components...I revised the schematic a little bit (changed how the LED's work)the PCB layout design...the PCB design with silk screen, no jumpers, parts neatly lined up, single sided board... disregard the text that says LM371, its already been fixed to LM317, lol Edited February 15, 2009 by 12oclocker Quote Link to comment Share on other sites More sharing options...
flounder Posted February 15, 2009 Report Share Posted February 15, 2009 really nice... I love projects... Im trying to get my hands on an oscilloscope right now. I really dont need it but I may be able to get it for free. Quote Link to comment Share on other sites More sharing options...

NinjaNick Posted February 15, 2009 Report Share Posted February 15, 2009 (edited) I've known 12oclocker for a long time and he always makes me laugh sometimes when he tells me shit he's up to, because he is THE SMARTEST dude I've ever met so far. I always listen when he preaches because it's like he can do anything..lol. No shit!His programming knowledge is incredible too. I swear he knows every language out there.

I love doing this kind of stuff in my free time, too! I don't know enough to design a bunch of stuff like you though. I had a quarter of basic electronics lab in college and still have the book so maybe I'll pick it up and read it. For now, I just use other people's designs. lol The biggest thing I've done was putting together a fuel injection controller for my jeep. My next project is going to be building a programmable aquarium controller. So, I'm interested in how you etch your boards and all that jazz. P.S. When are you going to be design a 'Power Commander' for us? Quote Link to comment Share on other sites More sharing options...

My next project is going to be building a programmable aquarium controller. So, I'm interested in how you etch your boards and all that jazz. P.S. When are you going to be design a 'Power Commander' for us?Here is the board process I developed through experimenting, it works really well...1) Prep PCB with fine steel wool, oil from your fingers will cause toner to not stick.2) Print on laser printer, Cut out design. (Use HP Glossy doublesided Brocure Paper) (HP 4L Laser Printers work the best, because the toner sticks better)3) Position printed design over PCB, run through laminater 5 times. the laminater will lightly fuse the toner to the board.4) Using a Iron set to linen, place the PCB on top a brick or metal pan, paper side up, place iron on top of the PCB, put pressure on it for 3 minutes. (this is what fuses the toner to the copper)5) Place damp warm folded rag over the PCB, and quickly put pressure on it with a brick or something flat and heavy for 60 seconds. (this is an important step that presoaks the paper without letting the edges curl)6) Now place PCB in room temperature water for at least 1 hour (the longer the better). (if the paper curls and rips a trace off, you didn't do step 4 and 5 correctly)7) Carefully peel the dissolved paper from the PCB board. If any traces broke, then you didn't apply enough heat or pressure during step 4. start over at beginning.8) Etch board.9) Clean toner off with steel wool.

12oclocker Posted February 15, 2009 Author Report Share Posted February 15, 2009 Whoa...that's awesome. I've been dragging my ass on my project b/c of the cost of etching the boards. Thanks man!no problem, steps 4 and 5 are key process steps. once you got those down you'll make a perfect board every time.if you burn the paper during step 4, you have the iron set to hot, slightly trim the temp back, hottest you an get without burning it is the perfect temp. when applying pressure, just use moderate pressure with the iron, about equal to the weight of 2 bricks.Step 5 is very important, its best to position the folded damp rag UNDER a brick, then quickly squish it down on the board, and put AS MUCH PRESSURE AS POSSIBLE on the brick with your body. your basically trying to soak the paper on the board with lots of pressure, to keep the paper from curling up (because curling will rip the traces off) after about 60 seconds. once the paper is soaked under pressure, it will not curl off, and its safe to drop the board in some water to finish the paper dissolving.

12oclocker Posted February 16, 2009 Author Report Share Posted February 16, 2009 Revised schematic, added current adjusting capability, and better short circuit protection, as well as better battery reversal protection....F2 can use an auto resetting board mount fuse, or standard glass fuse.

flounder Posted February 16, 2009 Report Share Posted February 16, 2009 Good call on the safety features. Hell, I think the most expensive part in the entire design in the transformer. Do you have a local electronics shop that has a good stock or do you order most of your stuff online? Also, what program are you using for design, testing and PCP board layout. I used to use PSpice frequently but havent messed with circuits in quite some time. Quote Link to comment Share on other sites More sharing options...

I used to use PSpice frequently but havent messed with circuits in quite some time.digikey or mcm electronics in dayton have the best prices on parts and stuff.Im using ExpressPCB software, its a free program, simple to use and has all the features I need. I like it better than the paid programs I was using. Quote Link to comment Share on other sites More sharing options...
xtremef4i Posted February 17, 2009 Report Share Posted February 17, 2009 Nice work Brooks. By the way, I think I passed you on our way to Dinner. you were going North on Dorset and we were going south. It was around the Rt 718 and Dorset intersection.

12oclocker Posted February 18, 2009 Author Report Share Posted February 18, 2009 (edited) thanks guys...here are the new PCB board layouts with the new protection circuit and current adjust... no jumpers, I got all the capacitors, transistors, and diodes aligned same direction for simple assembly.
