02622 Johnny Builds an ESR Meter. Episode III

[@andycraig7734]

Surface mount makes sense to me for mass production where devices need to be small. For personal builds- it's through-hole as much as possible. Bodge wires are certainly easier.

Long answer: 'Yes' with a 'But' Short answer: 'No' with a 'Maybe' The big plus for me is space and variety of parts/ All of my SM part can fit neatly in 1 drawer, while I have a full wall for about the same number of through hole. One other problem, very few if any ICs are coming out in DIP packages, and many older IC can no longer be found in DIP TI for example no longer makes 555 in DIP. If you want to use a very high quality audio op-amp you would be very hard pressed to find something in a DIP package. You can of course mount a SMD on a breakout board but that really just adding an extra step. Thanks for the comment, Don't forget to subscribe.

PCB-Way

[@byterock]

Yes that is an option. But what am I going to do with 9 left over boards. ;) In this case I made a few goofs on the layout not sure if I could correct them on a PCB-way board.

Pregunta. : Si el circulto funciona porque no mostrar el diagrama?. Why?.

[@byterock]

Here is the basic schematic www.qsl.net/w/w2aew//youtube/W2AEW_ESRmeter.pdf Not my design. The only major change is I used a LM555 for the square wave generator with a 56pf timing cap and and 47K for Resistors the to get a 100Khz square. Send me an email and I can send you my version
