jim6918 Posted March 8, 2009 Share Posted March 8, 2009 OK I will admit up front, my soldering skills are pretty basic. I am pretty much an "all thumbs" kinda guy. Just how much skill does it take to assemble one of the EDM kits?If we're talking fine detail soldering on circuit boards, I am pretty much in trouble to start with.I live in a pretty small town so the Whole House transmitter would have 5 available frequencies, but I question it's durability and range based on comments here.Honest opinions please.

Danbel Posted March 8, 2009 Share Posted March 8, 2009 Very easy just 3 or 4 piece I did what by my sell.And they are not small small piece:dude: Daniel Link to comment Share on other sites More sharing options...
Mark h2o Posted March 8, 2009 Share Posted March 8, 2009 I started with the whole house unit and it did get the job done. It seems to be sensitive all sorts of factors resulting in lots of mixed results, more good than bad tho.For me I couldn't get rid of the background noise and interference and it drove me nuts. However the people who came to watch didn't notice it as much but is was bad enough to make me switch.I ended up buying the EDM LCD from Scott and am very glad I did. After I set it up I didn't touch it the entire Christmas season and now I use it at work to broadcast mp3s on a couple of stereos in the shop. It's a very clean signal, even with the little test antenna and it goes a long ways.Soldering was very easy. Basic skills should get you through just fine. About 10min is all you need once you get going.It sounds like where you live the whole house unit would work for you but remember, you get what you pay for.Good luck Link to comment Share on other sites More sharing options...
cenote Posted March 8, 2009 Share Posted March 8, 2009 The one piece you have to solder is huge in size compared to most kits. Will take you longer to heat your solder gun up, than to actual solder. More people have mistakes in theses kits, insert the chip backwards. I say go for it to all beginners. Link to comment Share on other sites More sharing options...
doublea Posted March 8, 2009 Share Posted March 8, 2009 I never soldered before and this was a very easy thing to do!I recommend it! Link to comment Share on other sites More sharing options...
GalenInTn Posted March 9, 2009 Share Posted March 9, 2009 Okay, I've got a question. Maybe a few. What is an EDM? I assume its a FM transmitter. But what makes it better than the Whole House that they offer at LOR? How much do they go for? Where do I get one? And why would I want one?

jim6918 Posted March 9, 2009 Author Share Posted March 9, 2009 Thanks for the advice.When I read the words "solder" and "electronic equipment" in the same sentence I get a vision of guys in white tyvek suits with hair nets in clean rooms building something destined for the planet Krypton. Thats' why I opted for the slightly more expensive LOR kit that requires just a screwdriver. LOLGalenInTn:I hadn't heard of EDM either until I searched on the forum for FM transmitters. There is a pretty lively discussion about the pros and cons of Ramsey vs EDM vs Whole House FM transmitters. Sounds like the Whole House transmitter works for some but not others. Generally, I picked up that the EDM seems to have the least negative points. Link to comment Share on other sites More sharing options...

jim6918 Posted March 9, 2009 Author Share Posted March 9, 2009 Jeff Millard wrote: You folks who have some bizarre fear of soldering, please watch this video. Then go online to Mouser.com and get an inexpensive soldering station. Go to Radio Shack and buy some parts and a couple project soldering strip boards and practice. Or you can get small practice soldering kits from Ramsey.com that flash LEDs (in the shape of a Christmas tree if you want) There's also Carl's Kits for fun stuff. This isn't rocket science. I'm a complete idiot and I soldered half of the 16 LOR controllers for my display, and a Ramsey FM30B. I designed a DIO buffer board and had a friend get it manufactured in Hong Kong, then soldered it all together to add 144 on/off channels. As long as you are careful, practice a little, and make sure you have the parts oriented correctly and have them properly seated before you solder them, these kits are very easy to assemble.There's an entire community of people who refuse to purchase factory assembled hardware. Their reasons are many and varied, but some of it has to do with cost. I don't buy soldering required kits for the savings. I buy them because they're fun to build. I put one of them together yesterday afternoon while watching TV. Yep, watching TV. :cool:JeffSorry I posted this question now. Just following the advice of LightoRamaDan who said in his sitcky that "there is no such thing as a dumb question."Maybe it's best to just be a lurker.

Jeff's post was kind'a humorous.I got a lot of info from that post actually and I would not have learned anything had you not kept asking questions.For me soldering skills would be an oxymoron and I need as much info as possible since I have two PC kits coming.So keep asking, these guys really have all kinds of info to offer.

ken collins Posted March 9, 2009 Share Posted March 9, 2009 I just grabed whatever electronic device was headed for the trash heap, and started heating componets. The skill isn"t in the soldering, its in the un-soldering Link to comment Share on other sites More sharing options...
Max-Paul Posted March 10, 2009 Share Posted March 10, 2009 Come on guys, Jeff is just trying to show you it is not rocket science to solder. Hell I am 50 and started on a frequency counter kit when I was 15 yrs old. And now you know how many years I have been soldering. I have to tell on myself, from time to time I still get in a hurry and do a cold one now and then (by cold one, I am speaking of a cold solder joint).Important tips: Clean all surfaces, make the wire lead and the copper pan on the circuit board shine. If you do this, you are almost 100% guarrented a good joint. Wet the tip of the soldering iron with a small bead of solder. Then apply the tip to the lead / pad joint and apply solder wire to the oppasite side. Wait a couple of seconds and the heat will melt the solder. Wait one or two seconds more and remove the iron. It is that simple and like Jeff said, get a small cheap kit from either supplier and learn on the kit. Once you do it, you will realize how easy it is.Why do I do it? Savings, keep in practice, satisfaction that I built it myself. Well ok the board was etched by someone else, someone elses design, and they provided the parts. But I have etched my own simple boards in the past, but that is awhole nutter art form in itself.Do not cringe and back away from this. If you do, you are robbing yourself from a good part of this hobby. Embrace a chance to expand your abilities. Hell how do people go through life with out soldering. I do not know how many other activities that I have used this skill in.Just Do It.Max Link to comment Share on other sites More sharing options...
beeiilll Posted March 10, 2009 Share Posted March 10, 2009 Please don't be intimidated by the soldering part. As long as you follow some simple basics and pay attention you can do it without any troubles.Most common mistakes are putting something in backwards or in the wrong spot, but with the LOR kits it is pretty tough to do unless you don't pay attention.I have assembled 9 of these kits so far without any problems and now am starting to build up my controller cabinets for them like this one that I have started. I built these 4 boards and am in the process of wiring them up. I plan to make 3 more of these cabinets for controllers during this summer.Heck half the fun of this "hobby" is building things to me.Bill Attached files Link to comment Share on other sites More sharing options...
sjmiller Posted March 12, 2009 Share Posted March 12, 2009 I agree with Jeff and Max-Paul, soldering is not hard - and once you learn the basics, you can solder wires and circuit boards.As suggested buy an electronics kit, and a soldering iron. You will also want to buy flux, and I recommend flux cored solder (for circuit board work or tinning wires (1/16" diameter solder). You should also have a damp (not wet) sponge handy.The first time you plug the soldering iron in - let it get up to tempurature , then dip it into the flux - as soon as you pull it out of the flux push the solder wire against the tip until it melts and coat the tip up to about 1/8" above the bevel. The iron is now ready for use - it is tinned.Before you solder stranded wire to any thing - you need to tin it.- Get soldering iron hot- Strip insulation off wire, twist the strands together, dip the wire in flux- wipe the soldering iron on the damp sponge - tip should look like shiny silver- put solding iron tip on one side of the wire, after a few seconds push the solder so it contacts both the tip and the wire. Once the solder starts to melt - you will see it wick towards the wire insulation - pull the solder and iron away. The wire is tinned and read for the next step.- Most flux is now organic - use a wet paper towel to clean the flux (brown residue) off the wire.- If you are now going to solder the wire to a circuit board, use a pencil eraser to clean the circuit pad (rub the eraser over it a few times).- Now apply the tip so it contacts both the circuit pad and the wire - push the solder up against the other side of the wire - once solder starts to flow, remover the solder and tip when there is a concaved joint.If done right the solder joint will be shinny, a cold solder joint will have a cloudy look to it.Steve Link to comment Share on other sites More sharing options...
Max-Paul Posted March 12, 2009 Share Posted March 12, 2009 Steve,Great job of filling in the holes that I left, very good detail discription of the process. Only thing I do differently is that once the iron has been wiped on the damp paper towel or sponge is that I put a small bead of solder on the tip. Just enough to "wet" it. This helps with the transfer of heat to what ever you are soldering. Helps with the hit it hard and fast rule that I have about soldering. Otherwise I would nominate your input to go into a sticky somewhere about soldering. (Two thumbs up emoticon goes here.)Max Link to comment Share on other sites More sharing options...
sjmiller Posted March 14, 2009 Share Posted March 14, 2009 Max,That is another great tip - you always put a dab of solder on the tip to facilitate heat transfer.I'm going to open new newbie thread - Building your first kit (I started my first build today) and old habits from my technician days in the Air Force and Aerospace came rushing back...Steve Link to comment Share on other sites More sharing options...
Max-Paul Posted March 14, 2009 Share Posted March 14, 2009 Steve,What did you do back in the days of the A.F. I was a 30474 at one time, a Ground Radio Repair Tech (ground rats as we were kniknamed). But I started earlier than that with soldering kits as a teenager. Been soldering ever sence. Plus an Amature Radio with Advance ticket.Back in the earlier days I lifted a few pads myself. Esp those darn single sided board with a pad that went no where. I remember working on a few boards that were conformal coated. Had to use a xacto knife to scratch the coating off so that my iron and solder sucker could extract the solder. Found I had to scratch the best I could the coating off of the top side too. And blown away traces replaced with wire wrap wire. The only thing I refuse to work on is those new surface mount boards. No way to work on them without the expensive tools like the hot air desoldering / soldering.Max Link to comment Share on other sites More sharing options...
sjmiller Posted March 14, 2009 Share Posted March 14, 2009 Hey Max,Very similar background, I also started with electronics in junior high and made a living of it for many years. I've had a CB license (this dates me!), Amature radio license, FCC class B license. In the Air Force I was 32450 - Precision Measuring Equipment Specialist - microwave, RF (generators & counters), O-scopes, AC & DC standards, Phase, and RADIAC calibration and repair.The LOR controller is my first serious kit in about 20 years - and for the record it is a high quality kit with great instructions. When I started the build - all of my old good habits came to mind and I thought that it would be nice to document the build as it may fill in some gaps for a total newbie.Steve Link to comment Share on other sites More sharing options...
beeiilll Posted March 15, 2009 Share Posted March 15, 2009 Hey Max and SteveI too "did my time" in the USAF as a 32571, Aircraft Avionics Instrument Systems Specialist.Spent many days crawling around KC-135 tankers, B-52's, and 747's. Ahhh, the good ole days.I started out building Heathkit kits as a kid along with model rockets and was always tinkering with TV's and whatever electronic stuff I could get my hands on. Had a CB license myself (yea doesn't that date us!) and completed a "Mil Spec" soldering course during my last 2 years in the service. Ran a shop building automated test equipment for 5 years after the service where I set up a wave soldering line for the company I worked for.I still love to build this stuff although now my primary soldering is installing plumbing and heating systems. Just bigger solder and more heat :shock:.I also do a lot of computer repair work for people in my spare time, but it is getting harder to keep up with the technology nowdays at the rate it is progressing. So these kits are a great way to keep the hand in practice at the basics as well as providing a new hobby.Now if I could just find a 1000 watt magnifying light as the eyes get older things would be golden .Bill Link to comment Share on other sites More sharing options...
