Hi Apocalypto,

I believe everything required to build the delta pulse has already been posted, perhaps just not all neatly packed.

The schematic you attached in your last post in Eugene's thread is the correct one. As far as I know the correct single layer PCB is available from the son.lay file which I've attached here. Use the free Sprint layout viewer to access the file. Eugene has also posted a list of the parts.

Since I'm also building this project, I've tried to understand the circuit as best I can, checking the differences between the older and newer schematics, and the changes are fairly minimal. The changes are shown in green for new values on the latest schematic - C!, C7, R1, R5, R6, R47, R48, PR1, with additional resistors R50, R51, capcitor C32 and ultrafast diode.

It seems that the working son.lay pcb can accommodate these changes in the schematic without needing to change the pcb layout.

I'm adding part numbers to a graphic of the parts layout file which I'll upload once done - usefull for identifying parts on the PCB.

Cheers

Xero

Hello Everyone . To reduce some recent confusion because of all the schematic and PCB versions . I have decided today or by tommorrow . Post a "locked topic" of final project packages . Right now we have 3 PI projects 1. Delta Pulse / Snifer-xr71 [single sided PCB Circuit Board] 2. DBP 2010 PI [single sided PCB Circuit board] and last number 3. DBP 2010 [that has 2 separate single sided PCB Circuit boards] .

I will put together the complete , best and most recent files for each project . No more confusion . I now have all the best files for everything . the 3 choices which will be put in 3 zip folders and labeled "Final" . It will be a locked topic , meaning it is a "Read or Download Only" and should take up very little space on this forum . And after that any technical or performance questions can be asked under the appropriate previous posts .

Remember you can build any project using a breadboard of your choice and also rememember there are wire wrapping tools and IC sockets available for your first prototype . You do not have to order an expensive PCB circuit board from Over-seas !!

HH............Eugene

hello

Delta_Pulse_parts_list_updated_11-19-09 ....says 3 x470uF are this 3 cap gone for one 10.000 ?

Site is also in english
nice work of Rfelektronikk..and not expencive

other pcb is garys pulse 1+2
good
pictures says 2010 that is the year picture is taken of my deltapulse pcb

where is STTH1210D in part list,,substituted with 1n4001 ?
and part list say 3 x 4700uF ,,but it dont mention the 10.000uF cap

i also think spes of 4066 and 4538 should be defined in part list
where ever it is a tll cmos .. or what 4066 ?
i will order tomorrow parts from china..a priv contact she also have LF357..
i will buy several lf357 ..as they are hard to get in scandinavia
if there is any intresst of Lf357 i can order more and send..
