content: I bought the full on MEGAPC kit D (nearly £2000 if bought individually or just over £1700 as a kit) which includes the following items. It was really handy whilst making prototypes being able to design a circuit and disappear to the garage coming out 2 hours later with a circuit board complete with holes, vias etc...http://www.megauk.com/pcb_kits.php1 x PA310 Tri-Tank1 x LV2041 x Etchant for 5 Litre Tank1 x 4006V05 Developer1 x Pack of A4 LaserStar Film (10)5 x sheets 100 x 160 SS & 3 sheets 12" x 18" Microtrak1x SN4010 50ml Universal Solvent for stripping1 x Tin 1 Litre1 x PC190 Tray For Tinning1 x PC182 Scrub Block1 x Dremel Drill, 1 x Drill Stand3 x Drill Bits1 x DM9001 12" ShearThe above is what is in the kit when you get it but obviously I have bought it and been using it so some chemicals are run down a bit but there are more of other items:extraThrough hole rivets or 3 different sizes seehttp://www.megauk.com/through_hole_rivets.php*More PCB blanks than normally come with the kitFar more drill bits than normally come with the kit and of various sizes (these are not cheap either!)Printing laminates (probably more than the kit had from memory but not quite sure)PCB stripping chemicals (there is a full new one plus what was left of the original)Oxalic acid - for removing PCB etching chemical stains* You can use the Favorit through hole system without the press etc by placing the rivets into the holes then place a broken PCB drill of the right size into the open end of the rivet then tapping it down with a tiny hammer (provided) then apply heat and a tiny bit of solder.missing/usedNot much tinning fluid left (and if it has a use within a certain time then it's over that)Will need some ferric chlorideWill need more developer but there is a new small packet of developer just to start withAll in all the extra parts are worth more than the bits that have run out. Everything is in excellent used condition but obviously the PA310 tank has the normal ferric chloride staining that you get from the first time you use it. I will attack the tank with some oxalic acid tomorrow and post images so will try and get most of the staining off but basically it's a few brown stains on the yellow plastic and even if I do get them off you will re-create them when you use it.I can post some examples if people want to see what it can do but basically it will create really good prototype boards.Just in case you haven't done anything like this before it's quite simple:Design circuit & PCB in 1 or 2 sidesPrint mirror image of top and image of bottom onto the special filmPlace the two films together so that they line up and tape the edges together around 3 sides creating an envelopeUse the shears to cut a piece of PCB to the exact size you needRemove the film off the UV PCB and slide into envelopeClose the 4th side with tape making sure you catch the edge of the PCB so it can't move in relation to the designPlace into UV machine for 180 seconds per sideRemove from envelope and save for re-usePlace into developer tank for time that it says on the bottle (30 seconds from memory)Place into washing tank for a minutePlace into etch tank for as long as required (you can pop it in and out till its etched)Place into washing tank for a minuteScrub PCB with giant PCB rubber to remove etch resistOptionally tin by placing in tray with tinning liquid for several minutesDrill holes using the drilling stand and dremel (various drill sizes)Fit vias/through holesDone - Probably about 2 hours for a 4"x6" board.I'm not sure that I actually want to make PCBs anymore and it has too much value to literally sit there. So I'm wondering what it is worth to people? There are other things I want get to assist me so I thought I would see what people might have to offer in an exchange. I only want to sell/swap this kit if what I get improves my hobby over owning this lot.Happy to discuss either on here or by PM but I can't just sell the odd bit of it as it then isn't any use to me.
