Hi y'all! im new here my English is not so good (for an american) and i dont generally use forums so bear with me XP
i recently got a TI BQ32000DR RTC in an 8 pin SOIP package and i want to use it in a threw hole perf board so i used somthing i have dont before and stuck in a bunch of snipped leads in to the 8 pin DIP socket and soldered them in place .. than flipped the pins up side down on the RTC and pressed them on too the top (to keep the same pinout) and bent the leads down and snipped them than soldered them on (with my shaky ass hands) and got this
Oh yes it is slopy i know i just have really shaky hands and only a magnifying glass!

Also a big fan of the EEVBlog! Keep it up mate!

Cool.
I prefer to use machine pin sockets for this.
-
same here generally but this is all i had at the moment
it was a bit harder to solder the leads but in the end it worked out fine seeing how it was just going to go right in to a perf!
-
Nice idea! I used the other side of the pin headers :D

oh wow nice! i would be wayyy to paranoid to do that XD ... if i ever got the balls i would have put it on a perf or handled it like it was a $100,000 scope XD

These days we need to that all the time, DIPs are almost dead...

Yep. I used to bitch all the time about manufacturers not making DIP versions of things for prototyping, but eventually I just gave up and started making my own... SOICs get soldered into DIP sockets with wire, then hot-glued to protect the wires. I've got some quick breakout boards I made up one day for smaller stuff (I particularly like the ones for SOT-23 and SOT-223 that are TO-220 form factor). Then it all gets white heat shrink tubing over it so I can write the part number in black marker.

This texas board is a reasonable bit of kit to have handy for making your own plugins

not gonna lie, thats freakin expensive.

27cents per an adaptor is pretty reasonable I think.

No it's not, the chips going on them often cost less than that. I make my SO8-DIP8 adapters out of these (http://www.mouser.com/ProductDetail/FCI/DILB8P-223TLF/?qs=sGAEpiMZZMs%2fSh%2fkjph1trsk3O0a2elqycTEeDCVfAg%3d) - beat $0.07. Smaller adapters (SOT-23, etc) are made from scraps of phenolic PCB that would have been thrown away otherwise - beat $0.00.
-
Prototyping is always going to be more expensive than production runs. You are not going to use this for anything else than prototyping or one-offs. The $0.07 sockets are only a better alternative if the time it takes to wire it up and solder it over a proper PCB isn't worth $0.20 to you.
-
How about we make libary of PCB designs for typical SMD to DIP adapters?
If [or rather] when i make some for me i'll share them. Software: old protel

It's not, because I'm not doing it at work and so wouldn't be paid for that time no matter what I used it for. Your free time isn't worth anything unless you spend all of it as overtime at work or you don't actually have any.
-
Or if your free time is a limited resource that you would prefer to spend some other way than fiddling with home-made adapters.

Mike from Mikeselectricstuff.co.uk has a nice protoboard he made for this that has the whole lot in one, and is designed to be cut up into pieces as well. Check with him
-
I had to make these just the other day. These things just keep getting smaller. Meanwhile my eyesight isn't getting any better.

Tell me about it, went today to optometrist and got the good news I need multifocals. They cost about the same price as the equivalent mass of gold. Good news is that the far vision is unchanged from what it was 5 years ago, and the near vision I had done the Jerry Pournelle way, to be the best at a comfortable viewing distance from the monitor, rather than for a book or newspaper. Optometrist as well has done some upgrades, now using a Mac pro 21 inch as the chart display. Next upgrade I suggested was getting the second 27 inch display and putting it on the wall and use it as well. Interesting technology in use there, to measure the curvature of the cornea, and to measure intraocular pressure, using a small soft hammer hitting the eye and reading the force.

i can order some of those adapters and wait a week than solder it up or i could have just slapped it on to a DIP socket in 15 minutes ....

OT: I have iritis in left eye, those soft hammer type intraocular pressure doohickies are really cool, beat the hell out of the other handheld ones that have to be pressed firmly on your eyeball while you look directly ahead (after they put numbing eye drop in). Some times it is over and done with nice and quick but if the operator is not very experienced it takes them ages and many pokes of your eye to get a reading. When I have a flare up my vision in left eye becomes really bad and I lose my depth perception which makes soldering tiny things really difficult, like soldering with one eye tied behind your back ;)
