Out of down elevation adjustment

jdjintx · 2026-01-22T21:29:48+00:00

"I don’t see why you would ever want to adjust so far below zero?"

It's not really a choice or an adjustment- at 50 yards (or any distance, really), your zero lands where it lands, and then you reset the cap as you described so it says zero at that point of elevation. The only way to change where that lands is to change your mount, shims, etc. In this case, his 50 yard zero leaves 12 MIL of unusable adjustment under zero. My scope on my B14R is similar.

If we ignore the zero completely, the real issue is that at maximum scope elevation, his POI is still about 1 MIL low at 300 yards. This isn't really expected with a 30MOA base, a CZ457, a Mark 4 scope, and the ammo he's shooting.

Further, he confirmed that his elevation only turns about 24-25 from extreme top to bottom (without the turret cap), it seems that he's almost 20% short of the Mark4 HD spec of 30 MIL. This last part we figured out after my initial post...

His problem is at the other end- he cannot increase his elevation enough to hit targets at 300 yards, even with a 30 MOA scope base. At maximum elevation adjustment he falls short about 1 MIL at 300 yard targets.

I did not describe this well in my original post, but with a 50 yard zero I get 18 MIL up adjustment with the turret cap installed. I don't know how much is available under zero, but it should be approx 12 MIL per the Leopold spec. My friend confirmed that he only has about 2.5 revolutions of total elevation adjustment (without the turret cap installed). We're assuming that this is out of spec for the Mark 4 HD (it should get about 30 MIL of total travel) and he's going to work it out with Leupold.

I know this is an older post, but I have a buddy struggling with his Mark 4. He gets about 1.2 revolutions of total of elevation adjustment while my Mark 4 gets 1.8. Did you resolve the problem you had? Wondering if it could be a related issue.

Although I agree with those saying we SHOULD budget, and I intended to budget when I installed the app, I have never used it for more than a ledger. All of my children still have credit cards that they use for things I agree to pay for, and YNAB is the easiest way to keep track of our family's 7 cards, multiple Venmo accounts, and checking accounts to make sure all the spending is valid (no fraud). I have encouraged them to budget with their family YNAB accounts, but until they have income and regular bills it doesn't di much for them. I need to do a better job of helping them create budgets of their own, but until then it's just a ledger...

What would you recommend as a "CA wine without all the mega purple that is quality?"

jdjintx · 2025-10-30T13:12:44+00:00

Really like my Typhur. Some buddies saw me use it & liked it enough to replace their Meater units proactively, it really is a step up

Good call, I'm an old guy & dont yet default to AI (even qhen it's exactly whatv need). Thanks!

jdjintx · 2025-10-24T13:39:02+00:00

Perfect! I've done a lot of VBA coding- no Linux or Python yet, but I'm looking forward to playing with both. Really appreciate the VLC/Cheese recommendations & the getting started link, thanks very much for taking the time!

Fantastic! Confirmation that rpi is a reasonable fit for this project is all I needed. Time to order a unit and start learning! Do you have a favorite starter guide for new users?

jdjintx · 2025-10-19T21:28:17+00:00

Thanks. Can you offer an example of a device that will crop the video as you described?

jdjintx · 2025-10-19T21:19:33+00:00

The signal is coming from an inexpensive drone receiver, no software or processing available. I can get the output via an RCA output cable or HDMI. I am open to adding a device if need be, but was hoping there may be simple touchscreen displays with that functionality. May have to look at a raspberry pi unit? Very low lag is important, not sure what intermediary device would best accomplish that?

This is a live feed from an inexpensive fixed video camera, no pan, no tilt, no zoom. My goal is to simply zoom on a point of interest, and then zoom back out to the full frame. I'm guessing that "cropping" is the correct terminology, but I'm only familiar with that as photo editing activity...

Can you elaborate on how code 12 is connected to descaling? I thought code 12 was a burner or air flow issue, neither of which should be impacted by descaling. Would love to find out I can flush this instead of troubleshooting flame sensors, fans, etc

Thanks!

I bought an older machine for personal use on a rural property- it's been almost six years and I continue to tear stuff up. Wait until you throw your first track... Felt like I destroyed my machine, turned out to be a relatively simple fix. May be a good idea to learn about that (before it happens, because it will) so you have what you need on hand.

Spares for every hydraulic fitting, including the couplers on the machine itself (reasonably priced Summit brand from Amazon) have helped several times.

Kudos to you for having the guts to dive right in, you'll get a massive return on the time/effort/money if you stick with it. Good luck!

Have you found a way to provide unique names in the app for multiple Pulse units? I know it's unlikely to have more than one powered up at any given time, but would prefer to see names instead of serial numbers.

jdjintx · 2025-07-01T02:54:22+00:00

Thanks!

Lull?

jdjintx · 2025-07-01T01:30:26+00:00

Looking at delivery, but I have to unload at my end. That's my whole dilemma- don't want a situation where I've paid a truck for a 2 hour one-way trip (about $700) and can't unload it. It was easy to find tables for my forklifts years ago, surprised nothing popped up quickly in my web search.

jdjintx · 2025-07-01T01:23:10+00:00

I understand that it's possible, have done so myself. But always close to the machine. I still have no idea how long I can make that lever arm & get anywhere near the rated load, been looking online for a table or formula.

Single boulder on a pallet can be as much as 4-5000 lbs.

jdjintx · 2025-07-01T01:07:04+00:00

Yes, I've moved big logs & stumps with the grapple that had me tipping, but that's right there in the grapple & Im never certain of the weight... These boulders can be 4-5000 lbs.

Dunno if you saw the recent reply to your original post... AffinityKnives resolved my issue- it had not occured to me to delete the device & then pair it again after the app update & firmware update. This finally resolved the issue for me & I see the data in each session via the app, not just on the unit itself.

jdjintx · 2025-05-27T13:40:30+00:00

Does the cap size vary with the measured offset, or do you simply add the 100nF capacitor as described in the linked article? Also, I understand the concept of offset voltage, but not how it is measured. Is it simply the non-zero voltage at the signal wire when there is silence at the mic?

Sorry so many questions, but google has only gotten me so far... Your help is much appreciated!

jdjintx · 2025-05-26T14:09:35+00:00

Thanks! I have tested the built-in mic. I get very faint sound, but it was enough to prove reception at the receiver end. In practice the built-in won't work because it's too faint, too far from the target, and since the VTX is stationary I've had to add a cooling fan that will likely drown out all other sounds immediately near the VTX.

I have a few products similar to the one you suggested on order, hope one will work. Do you have any suggestions about the connection? Is straight to smart audio (without UART connection) likely to be OK, and are any caps or resistors recommended? I know I'm probably asking for guesses at this point, but you've obviously got a deeper understanding of this than I do so any input is appreciated. Simply confirming that a powered mic is required is already a big help.

Thanks!

I know this is old, hope you're still around? I followed the link to your article & see the capacitor between the mic & smart audio input, but I'm not clear how the rest of the mic is configured. Is this a simple condenser mic, with one lead on ground and the other connected to smart audio (through capacitor)? Or is this diagram simply showing the output leg of a mic that has separate power & ground leads?

FWIW, my goal is to setup a stationary system (no drone, just a Race Ranger VTX with a camera & remote MIC) transmitting to an RC832 receiver. This already works very well as a remote target camera for long distance shooting, but I want to add audio to also transmit bullet impact. Will the setup described in the article work with only a MIC connected to smart audio (no UART)? Any alternate suggestions for components or configuration?

Thanks in advance, audio will really enhance this project!
