In this thread, we post pictures and discuss the fun and wonders of using strips boards, perfboards, and wires point to point.

There are too many people with PCB work these days, it'll be fun and refreshing to see some "real"(hassle) diy work.

My work, a month ago. An adjustable diamond buffered desktop amp with improved current mirror for biasing.

A Cmoy i built half a year ago.

Portable Diamond Buffered Amp.

Post a pic of the underside of that first board! That's where we see your real work. Any schmuck can put parts on a board, how the connections are routed is another story

Everything in my signature is on perf boards at the moment, it takes up about .66 cubic feet of space with all the separate boards and connections. The PCB as designed is 8x6

pcm2906 DAC in perfboard? that would be killing project.

i myself use perfboard most of the time but dont have camera to take some shot. certainly my perfboard routing skill is not as superior as TzeYang does.

Here you go, i hope my first post doesnt ruin the intention of this thread

You are a machine.

I've always thought point to point wiring is really cool. I'd love to see some pics of that stuff and descriptions in this thread!

Simple Class A-B v1:

iHybrid Nano:

In both cases i was able to use sijosae's layout for major inspiration. Maybe later I'll show you my SOHA and you can all laugh at me.

Hi fellow P2P troopers

Funny stumbling across this thread , as I am just to embark on a bit of P2P work for a friends project.
Everything i have done has been made that way, dacs amps etc.
But the biggest pain for me is drawing up the layout, as you are constantly changing things.
I did a search and came up with this little app the DIY layout router:

.: Storm Software - Freeware :.

I have only literally started to play with it but thus far I think it could be very useful.

Happy weaving

The buffer/preamp section of the integrated amp I built:

The big black boxes are solid-state relays for the + and - rails. They turn on when the amp powers on.

I just lay everything out in Eagle first then perfboard it... it's a PITA, but I agree proper planning is needed.

It'll be awesome if we can use a software that actually does perfboard layout. I only use a piece of paper with little squares.

, gets the job done but i'd like to have a softcopy of the layout in my pc instead of a piece of paper lol.

wow, i like that perfboard. I am always a fan of that perfboard (very high quality, with pads on both sides), but seriously, they cost me an arm over here T_T



On a side note, i just finished casing the amp (first pic) i built a month ago.

TzeYang, that perf-board was from the generosity of the electrical engineering department at the US Air Force Academy (they let cadets use things, so yeah =P, I save a lot of money.). The power supply rails are connected to copper planes on the top and bottom. They can function in limited shielding (shields everything above circuit board in my amp, anyways).

That is incredible.

Any chance that you can give me a few pointers on doing such amazingly neat work. Mine invariably ends up all blobby.

My soldering method is quite contrary to conventional soldering methods. Not sure if you guys are interested but I’ll post it anyway.

Here is how I do it:

Required Tools:
Soldering Iron and Tin (doh)
Nail Clipper
Masking tape

The last two items are the key items to get a nice solder joint.

Firstly, whichever way you mount the components make sure it stays on it without dropping off. You can use a masking tape to temporary secure the component so it does not fall off. Next step is crucial, TRIM THE LEADS FIRST! This is the part where nail clippers truly shine! Their accuracy and ease of use beats even pricy “commercial tools”. Use nail clippers to trim the leads to appropriate length. They should be no “taller” than the intended soldering blob. Next, flow solder to the joint. For first timers, put as little amount of solder as you can, and then slowly fill it up until you reach the desired size. There you have it, a nice round shiny blob of solder joint! There are benefits to using this method. The solder flows much easier and the joint looks much cleaner.

I don’t know why but most of diyers who posted their pcb works don’t solder this way. They would always solder the components first and then trim the leads later. IIRC, Kin0kin solders this way too.
