Free 74HC14 Invert Schmitt Trigger...

Bamse

I managed to order the wrong part from Digikey...

In stead of a 14 DIP I got the 14 SOIC...
Maybe I should have had another cup of coffe before hitting the submit button...

So if you think you can use 4 CD74HC14M (Digikey part 296-9179-5-nd) send me a PM with your name and address and I'll put these in the mail tomorrow...

Experience level:
[noparse][[/noparse] ] Let's connect the motor to pin 1, it's a 6V motor so it should be fine.
[noparse][[/noparse] ] OK, I got my resistors hooked up with the LEDs.
[noparse][[/noparse]X] I got the Motor hooked up with the H-bridge and the 555 is supplying the PWM.
[noparse][[/noparse] ] Now, if I can only program the BOE-BOT to interface with he Flux Capacitor.

oh gosh.. i thought i had ordered 60 or 80 ceamic capactirors last week - they arrived, Surfance mount!

UgH! they are sooo tiny.. joke sized... at least all 80 were only like $4.00 total... being Surface mount... i am deathly afraid of these...

gotta be more carefull with that digikey..

Well want to solder SMD... Easy staff if you know... The fact that the caps have only 2 pins saves your day... You can solder them to a breadboard (well not the plastic one... I don't know how it's told) from the back side...



Now if you want to solder the 74HC14 you 'll need s costum PCB or if you are good in soldering you can use the dead bug method... solder it with wires upside down...

Hope I made you understand...

I think I'm just going to solder on some 24 awg wire and plug it into my breadboard...

I'll ordfer the real stuff (DIP) later in the project...

Bamse, see if you can find a "Surfboard" (a brand of break-out board), something like that, and you can get some SMD practice.· Everything will become surface-mount, DIP isn't a factor in production anymore and they don't knock out ICs at Maxim, Microchip, and National Semiconductor for the hobbyist market.· We get what's left.

Jameco has SMD to Dip boards that you can use.

I've also seen SOIC to DIP boards on ebay for something like $5 for 5 of them

stand back! I have a slide rule and I know how to use it!

I tried soldering 24 AWGs to one of the chips yesterday but my tip is too wide...
Got to sharpen it up and try again later this weekend...

You can order (i know that's a dirty word round here) a board that'll adapt the soic to wire connection, i think radioshack even carry's them

Bamse

I gave up...

I think it's probably easiest to just order some 74HC14 DIP from http://www.glitchbuster.com/...
He charges $0.25 per IC and shipping is only $1.95...

Those "Schmartboards" sound like a great idea for clumsy people like me.
But why are they so expensive ($10 for one protoboard)?
