Preston's Element 14 BOM Attempt

[Fred]

Battery Reference Voltage has been reversed to BVR which is wrong. Change back to BRV ASAP FYI TYVM.

[Fred]

MAP/AAP look OK, but:

1) the parts that are shared between on board and off board should be in "map common" and "aap common" sections, with only the differing parts in their own sections.
2) the order on the aap page is different to the map page still
3) the component that is in map extra to the other could be aligned to be obvious when flicking back and forward.
4) the html for aap renders funny with the mouser part number being unreadable in chrome on mac

EDIT: RPM page is also screwy, can you increase the width of it somehow? or is it dependent on the spreadsheet exactly?

Did I mention that i fucking hate binary files? Ravage is being done with Jammi's app, then it's diffable and a 5 minute operation to check shit like this.

• that zeners are NOT to be installed
• that only one of the resistors to the CPU is to be installed
• that it's to be 1k

Will be documented in Puma how too, I will keep them as reminder notes till then.

This is inconsistent with all of the other pages. It should have one 1k resistor and 1 jumper per input. It should show the zeners as excluded. The idea was to show everything in a circuit and all changes from stock right? It needs to go in the howto as well, but IMO it should be listed here with reasoning, otherwise people might trace it and be wondering. Please fix :-)

TPS seems to have only one cap, is this true or missed?

Yes one cap is correct, however it was a fantastic way to alert me to the fact I had used the annotes from schematic page 24 <---Wrong! corrected these and traced on PCB now correct, components them selves didn't change. Schematic pages updated in BOM. Please double check my work as flicking between these schematics is doing my head in.

Checking... looks OK.

Ignition:

• I don't see mention of a high power 12v pull up resistor to be used with the FET for ignitor use?

To be discussed/confirmed, Fred hit me up about this one.

call it 1w, 200ohm, and include 6.

Done ^ please add these to the list.

• R251 and SM stuff still needs pull up mod described and added.

As per about to be documented in Puma how too.

Sure, but you still need the part for it! Add a 10k 1/4 TH resistor for it. This can connect to the outer end of r251 and 5v somewhere. That way the system works correctly at all times and is safe.

It might pay to include a single PNP transistor for modding the FTDI setup just in case I can't get the SM stuff done in time. It will be done ready for ravage, though. I promise that much. Given how long you bastards are likely to take to get these up and running I guess it's probably OK to leave it out, but it's only a few cents and makes it complete.

OK, assuming that you didn't fuck up anything that was OK before, and that I didn't miss anything, and neither did you, I deem it OK once the stuff in this post and the last couple are mostly sorted. I'll do a summary post next.

[Fred]

Summary:

• Save and/or export on the correct page
• Fix BRV naming
• Remove "Puma" from "Primary Puma Parts" and end up with just "Primary Parts"
• Remove duplication and inconsistency from MAP/AAP pages
• See if you can make the inset part number links look correct in html
• RPM page is missing: Two 1k resistors, two jumpers (were 1k resistors), two left out zeners (note not to buy or install).
• Add 6 1w (or 2w) 200 ohm resistors to the ignition page
• Add a 10k 1/4w TH resistor for modding load/run setup
• Add a single PNP transistor, I used 2n5401, marcos used BC640 or BC558

Home straight now man! :-)

[Preston]

Great! I'll get onto this tonight.

By the way Fred, who had to wait 3 days for the review? an your calling us slow!

Preston.

:-p

• Save and/or export on the correct page

Done, I'll try to remember every time

• Fix BRV naming

Done

• Remove "Puma" from "Primary Puma Parts" and end up with just "Primary Parts"

Done

• Remove duplication and inconsistency from MAP/AAP pages

Done, with a tidy up and split into common, inboard and outboard.

• See if you can make the inset part number links look correct in html

Done, if it doesn't look correct on your end please screen shot that and post. Thanks.

• RPM page is missing: Two 1k resistors, two jumpers (were 1k resistors), two left out zeners (note not to buy or install).

Done

• Add 6 1w (or 2w) 200 ohm resistors to the ignition page

Done.

• Add a 10k 1/4w TH resistor for modding load/run setup

Done.

• Add a single PNP transistor, I used 2n5401, marcos used BC640 or BC558

1 x BC558 PNP transistor added for USB hack.


We should be good to order from this now, any future work will be purely cosmetic/linking to Puma-HowTo document for mods/changes - except for the generator page, which will come soon.

[Fred]

Great! I'll get onto this today - paraphrased! :-)

• See if you can make the inset part number links look correct in html

Done, if it doesn't look correct on your end please screen shot that and post. Thanks. - Checked - see below, it still looks bad.

• RPM page is missing: Two 1k resistors, two jumpers (were 1k resistors), two left out zeners (note not to buy or install).

Done - Checked - Jumpers still need part numbers, other pages have that.

Close! :-)

Will get you a screeny.... NOW :
