content: HelloI did a few tutorials on creating circuit boards at home. Check them out, if you want to make your own!It's a 3 part series. 1 intro, and 2 actual tutorials.I had to do the intro because the tutorials were already past the 10 min for youtube.I tried to cover as much as I could, to avoid people getting the "Why the .... ain't this shit working, man" moment.But if I missed anything, please let me know... and I know ... didn't talk loud enoughSorry about that, lesson learned-Mads

content: Very nice, I learned how to do PCB's using letraset and tape direct, and the marker method. How much do those dry films and solutions cost?

content: Quote from: SeanB on January 01, 2013, 08:29:59 amThanks...The dry film can be found on ebay.. I use this type, it is about $0.8 for one A5 size.http://www.ebay.com/itm/Photosensitive-dry-film-negative-photoresist-DuPont-MM540-pcb-20pcs-A5-/181052794388?pt=LH_DefaultDomain_0&hash=item2a27966614And the sodium carbonate (soda ash), should be easy to find.Here is a link. It is from the UK though, so the shipping might be expensive..http://www.ebay.com/itm/500g-Sodium-carbonate-powder-soda-ash-PH-dye-fixative-/130477605843?pt=UK_BOI_Medical_Lab_Equipment_Lab_Supplies_ET&hash=item1e611243d3- Mads

content: I can buy all those from my local chemical supplier...... Must get some in. Will do some testing on scrap brass and see how the plating works as a DIY.

content: It would be much better with another voice , just have to say it seems with any background noise [ coffee shop here ] the audio is about 50% useful .

content: I agree with the previous poster, the audio is depressing, especially on the first video.For me, it was very hard to understand you and hard to follow what you're doing, the first video was downright confusing.As for the second videos, they're more clear, but I feel too little time (or no time) was spent explaining exactly why those steps are required and what those steps actually do, why that process is required.The videos could also use some tips like having the pales of a pc fan immersed inside the liquid so that the liquid will be constantly shaked or moved around the plastic container.. saving you from actually having to move it yourself and stay with your nose above the substances which may or may not hurt your lungs.

content: Quote from: mariush on January 01, 2013, 04:12:27 pmSorry about the audio :/ As I mentioned above I should have talked louder. It does almost sound like I'm whispering.. My voice is not the clearest, but I should be able to do better :/I wanted to keep each video within 10 min, so I didn't have to split it. But maybe I should have made it a little longer with more explanation, tips & tricks and so on.. I could easily talk 30 min about each topic, I just think it will be too long and boring for people to watch..But I could be wrong of cause..Thanks for the response, it does indeed help me to improve any future videos..-Mads

content: Very nice tutorials, congratulations for making them.I'm going to add two very interesting videos I found on the matter - toner transfer using regular adhesive vinyl and tin plating with materials used to weld copper piping. The idea is that one can use whatever is easier to source.It so turns out that both creators of the videos are Romanian, so I can't be happier

content: Quote from: dr_p on January 01, 2013, 11:23:43 pmThanksAnd thanks for adding the videos.. The vinyl method looks interesting, I have tried "t-shirt transfer paper" but I'm getting small holes in the toner, could just be my printer though. I once had a Brother monochrome printer, that just did the job. My new color one is a little more trickyAnd the tinning is very nice indeed! Reminds me that I used to use Solder paste mixed with IPA (alcohol), that got brushed on and left to dry (a few min) and then baked it in the oven. Almost exactly what he does in the video.-Mads
