You guys have lost your mind, I'm ready to stick my soldering iron through my own eye. What is wrong with you??? That being said, anyone got a 1m I could swallow, mine is covered in solder.
A 1M resistor? If so, what package size? If it's 0603, I am fairly certain I could send you a few.
I've got a 0603 and a 0805. Would you like some?
The part number on the resistor is 1005. It freaking tiny. It's for Chromesphere's lpb1 starter kit
If it's 1005 metric that would be 0402. I don't have any that small.
Is it 0.04" x 0.02" (roughly half the size of 0805)?
EDIT: since that's a "starter board", I highly doubt he'd use 0402s.
EDIT2: I'm a bit confused because 1M would have 1004 marking, not 1005...
1005 is 10M I think. I may have some in 0805, will know in a few hours. Anyway, props for giving it a shot Jimi
1005 is 10M but there's no 10M in Paul's LPB.
Anyhoo, my offer stands. I have them both in 0603 and 0805.

ROFLMAO, Jimi gets at the very least post of the month.
Looks like 0603 on the build doc. If you have to put the iron in an eye, make sure it's not your one good eye—you might need it! A wee bit of patience as you lose many tiny bits while trying to get them on the board is all that's required. That and I never crack open that fifth beer until I've finished popping the board. ;)

Right, sorry. Duh huh. Yes if I could have 1 is be grateful.
A'ight dood. I'll pop a few in the mail for you tomorrow.

Hey Jimi! Glad to see I have scared the living !@#$ out of another forum buddy :D
They are infact 0805's. You can order replacements from tayda (my original source). Revamping the SMT kit is on the to do list, I think if I redo the board I might make them a touch more spacious. You know. An extra 1/2 mm here or there? haha

Nice, ha! At the moment, I believe the resistor is covered in solder. it's not unsalavagebale I don't think, but a backup plan is handy. The second resistor went on better than the first. I am going to go ahead and get some flux tomorrow.

Don't kid yourself, it will piss you off as much as an intermediate kit.

I've done a OKF on Mark's layout, looked like shit but worked! lol
Lol hopefully this will, then I've got the function fx board to do.... Msybe
Desoldering braid is manna from heaven when doing this SMD stuff. It's like a hand-trolley when transporting a Marshall quad.
Oh my! I use braid and a desoldering iron too. Braid works great on etched because it's flat as in not double sided , so I'm guessing it works the same way on e I get a flux pen, I'll be back in business.
your resistors are in the mail.
fwiw, i dont use flux at all when doing smd, only what's contained in the solder wire.
and if you decide you need more practice, people have told me my zen and barbershop gave them no grief whatsoever. i know you probably need another OD like an iron in the eye but they seemed to have helped some folks get their foot in the door without much hassle.
that said, if you manage to put Pauls board together, i'd say you are ready for everything. it really isn't on the roomy side. :)
I get this feedback all the time (small, tight etc). Prehaps I've let my youth get the better of me as I have built 3 of them without a hitch!? I realise we aren't all steady handy though so I think I will invest a bit of time enlarging the PCB. That said I do like the fact that this LPB1 is espionage electronics sized :D
SMT is the work of the devil.

Sold my soul, now buying others as I move up the ranks. Though nothing reeks of hell more than etching copper and drilling all them holes. ;)

I plead guilty to this, to the point where I don't like through hole components now!

D1 -9.1 v
R2-9.1
r3 -9.1
c2-4.5
trannie base-4.5v
Audio problem yields nothing at the input unless the ground wire and power are disconnected.

That's not half bad for a first go, and a tight layout. Not sure about r1, looks like one side might be off the pad. r2, and c1 might also need a little touch up.
U1 looks awesome, and that's probably the hardest one.
I'd probably hit everything with a little flux and reflow with a clean tip, no extra solder.
Hey man, sorry to hear its giving you trouble. I suspect its probably soldering error. For the signal path, did you check the schematic on the webstore page? Its here if you need it:
http://www.diyguitarpedals.com.au/shop/boms/CBFX_SMD_Practice_Kit_LPB1_Boost_schematic.pdf
Yeah I would reflow some of those joints and try again! The SMD (ahem...T :) ) practice kit was one of the first boards I designed and I think it desperately needs a makeover.
More space, no vias, etc. :) Let me know how you go.
i was gonna do a roomy layout of this way back but since Paul made his available i just dropped it.
plenty of other stuff to give a go, without toe-stepping :)
Chrome, I'd recommend you partner up with Muddy for the LPB. E's got 'is chops fer ti' simple SMD, loik.
-Ok! So I have just spent a bit of time expanding the size of the pcb for this project, from 1.75cm x 1.2cm to ~2cm x 1.5cm. Doesnt sound like much but now there is much more room between components! Although I honestly never had any issues with the size myself, i can understand not everyone is a dexterous with fine work as i am so the constructive criticism has been noted and change applied! I also think its a good idea, SMT components are so small, no point cramming them onto a microscopic board hah? :D It will take some time for the new boards to come through but i will order them on the next fab run.
Also i should mention, this isn't a very popular project, one of my least selling. But im investing the time and energy fixing it because i think its important to have something like this available for those that want something small to commit to, so they can decide if SMT is right for them.
Thanks for the feedback, I honestly mean that. I'd be totally in the dark without you guys letting me know your experience with my projects and where improvements can be made.
Paul
It was the starter kit that got me. I'll try reflowing,at be in a few days, right now I'm going through a few life / living changes and gonna have to move my "bench" to a different location. I'm optimistic though, u haven't let anything neat me
Yet, except for the one project I melted down. It was cool, but a mark in the loss column.
The only other change I could think of to make an SMT starter kit more beginner friendly is large component size. There are slightly larger chips that you can use, but I don't think they are as common as the ones im using on my beginner board. I think Rej summed it up, starter kit and SMT in the same sentence. Unfortunately Jimi, I honestly believe this is as easy as SMT can get!
No, it's all good. I think a smaller soldering tip kana great idea. I reD that after this attempt, and I discovered at micro size, I shake a bit. Who knew??? I think I can salvage it.
I hate to see a fellow forum buddy in crisis, let me know if you want to try again and I can send you out a new board. I've ordered some prototypes from oshpark, they take a long time to get here (about a month) but if you want one let me know jimi and ill send you the full kit again (for free of course).
Heres a picture of the update pcb. Looks much better, the old version is just a bit of a cramped mess really. This PCB was the first pcb I designed...for the record :D

Hi Chromesphere,
I would be interested in trying out SMD soldering, so do sell a kit or a pcb or something on your webstore that I could have a go at.
Cheers
Joshua
Jimi's first attempt is much better than my first. I just threw it away after I did it. I didn't even test it.
If through hole ever dies, I'll be done.

AMScope has some nicely priced microscopes from China that have decent optics and are built quite well.
Picture captured on my laptop with the $13 usb endoscope i'm using in my pcb drilling setup. Haven't yet tried using it as a viewer for SMD soldering but i do see potential.

I have one of these (well not that
exact one, a chinese knockoff that looks pretty much the same).
It's the bees knees, I'm extremely satisfied with it, especially for the price.
Yours looks a bit different than mine. Is yours a stereo zoom model?
