content: I'm looking for a few pieces of equipment. I'm located in Hendersonville, NC - so if you're local - great!For the multi-meter, I was looking at the 121GW and I like that it doesn't require 9v ( My current ones are cheap ) but I don't like that it can't do AC.... Logs aren't on the top of my list, but min / max feature is nice, etc... Being able to test a wide variety of components is a must... I may end up buying the 121GW and get something else for AC... Does anyone know if it is open-source? I am a developer with dozens of languages under my belt so if it is open-source I'd love to look at it to improve the speed...I saw the other thread for Flukes for sale but the 87V seems to be 'industry standard', and I'm not sure about the other models they have ( V isn't available, but IV is and I have no idea of the differences - but I do know they support AC )If anyone has one of those cheap color or not LCR Meters they'd want to sell ( preferably the one with the color display ) I'm interested in buying one.I'm also looking for an O-Scope ( I have to disassemble my large old one to fix it ) and a 3D printer...If anyone is upgrading printers and wants to sell me theirs, I'm open to offers - I do like the Prusa line but I'm open to others... 1 or 2 heads, preferrably able to print multiple types including the new solder type, wood, etc... so heated plate, and more...My budget is open.There are a few tools I am considering - LED tester and LCR meter by something tweezer company, but they seem pricy compared to other tools...I repair monitors, tvs, build computers, repair them, power supplies, and much much more. I'm also a software developer and I have built my own electroncs by ordering PCBs, soldering all, and flashing - I currently work with ST Micro chips..

content: For an meter find an fluke 187 or 189 50000 counts, brymen 8xx series 50000 counts with an special 500000 count in 3 modes range, if you want to log things you can buy their usb adapters at good prices. They are easy to calibrate too, personally not impressed by keysight, sanwa or kikusui meters ... or unless youre a purist to buy 3 gossen meters like me lollThe 121gw is not mature enough to my taste, but it will eventually, i dont think its fully open sourced if you read the 121gw threads, it was at 250, now at 300 pricedtoo high for my taste, unless you want to gamble lollfor an lcr just go for an deer de5000 very good and not expensive on ebay 100$ - 150$ kit, and you can put some tweezers clips if you want, i have the 20$ lcr thingy but not fully satisfied with it, i want kelvin measurementsThere is accuhard a101 an pc to usb lcr meter with pretty good specs 120$ usd with kelvin probes too ?? im waiting for a re-stocking to buy it ...for o-scope there's a few models who can be hacked for more BW frequencies, and doesn't costs a fortune too.

content: Cheers!Yeah, I saw the kickstarter for $250, then $260 and I would've probably purchased it for that but 10 days of backing only and with how little time I have, I didn't find it until now - months late... The site lists it for $330 with the bag, plus shipping likely which is $80+ AU more and that's too much on top for me too... It is designed / built by a reputable company so the fact that it is new doesn't bother me a whole lot but I have been looking for a good multi-meter for a while now and it has a lot of the features I like plus some LCR functions it seems ( checking random resistors, components, caps, etc... to find out what they are, etc.. if I interpreted the features, videos and text properly ) which would save me from buying some other utils...I am thinking of getting the $20 Chinese Color LCR meter ( It is open-source or at least a part of the project is so I should be able to reprogram it with features I want and speed up the processing of it ) so I have something for now....I'm currently debugging my LG W2252TQ monitor power board - I replaced 5 bad caps ( 1 was bad I replaced before then 5 went bad ) and now it just clicks - with backlight flashing for a MS then repeating every 2 seconds or so.... I've tried to see if either relay was the thing making the clicking sound with my stethoscope but the clicking is the same - and I've tried feeling around and I can't feel what part is clicking.... The clicking is likely it not getting enough power so I'm wondering if the caps, despite them being the right voltage and proper Farad value - but the clicking is similar to when a car is trying to start and there just isn't enough juice so the relays fail to lock... but could the transformer also cause the issue - or it could be the caps are bad or they're being discharged so ... I have some things to go over and I'd prefer a multimeter which actual capture min/max, and more to properly debug even though I've been right up until now with all of my repairs - but I'd like to be sure on this because a replacement powerboard is only $12 so... )And I have a LG TV 47LN5200 backlit using LEDs ( and if one goes bad then all go out ) which I got for $25 - going to fix it and use chromecast and a spare computer to stream nonstop German TV for myGrandmother.... But I'd like to go over other components since that particular tv is annoying to take apart so I'd rather not do it twice...As for the 3D printer, I have been working on a new design but I need a printer to build it and work through - it'll be a huge step forward for 3D printing.... I may just go ahead and buy one instead of waiting for one here.....
