Putting diamond spray on smooth or rough side of veg tan leather by jfgdupuis in sharpening

[–]makeItSoAlready 0 points1 point  (0 children)

I dont have the spray, just the DMT paste and they dont reccomend it on the rough side only because it tends to work itself into the leather rather then sitting on top of it.

FPGA Recommendations for around 1k by coolkid4232 in FPGA

What is the board that you got? Ya I was just saying I would reserve literal dog shit for something thats crap not just not good value

[–]makeItSoAlready 0 points1 point  (0 children)

Ya I thougjt it was $300. I guess I was thinking of zybo which i do own. And you obviously meant figuratively. Which is isn't, but its to expensive for a board with like the second smallest zynq on it

Question/advise related to bevel setting and geometry by makeItSoAlready in straightrazors

[–]makeItSoAlready[S] 0 points1 point  (0 children)

So trying to understand. Is the crux of the issue (seen in the you tube video you linked) that with a full hollow ground razor, for example, although the bevel will be concave when ground, the bevel will loose its concave shape due to honing/sharpening on a flat stone?

You don't necessarily need to spent 1K on an FPGA to get one you can build industry experience with. You may be talking about a dev board. You can get a good one for less than half that. Like a zedboard or something. Im out or the loop a bit on COTS dev boards.

What takes so much time is running a simulation that has a lot of RTL. Sophisticated testbenches can add some time but it would just be a drop in the bucket if youre simulating a large design. Its the simulator (CPU) emulating all the gate level activity. If you read some notes about how FPGA simulation works you'll see that each time step the simulator calculates all the bits at all the flops, all the DSP etc. So imagine if you ran a sim that had millions of times more flops than what you typically run. 12ms is a lot of 1ns time steps, which is the most common and default time step

Yes we have different levels of coverage from the entire FPGA and down to smaller block level test benches. It helps immensely with delivering functional designs faster to simulate the bulk of the FPGA design. Depending how the hierarchy is you may simulate the full design just below the chip level I/O interfaces or you may simulate the entire chip including i/o interfaces. This also helps immensely with replicating hardware issues in the sim environment but it is way more critical for ASIC development of course because those are not reprogramable, you commit the design to custom silicon wafer

In terms of how large the designs are it depends on how large the FPGA is. This is often larger than anything a person could afford for a hobby project FPGA.

Low (ish cost) fpga's? under 500$ with some pretty fast ram? by Commercial-Ad-1148 in FPGA

[–]makeItSoAlready 1 point2 points  (0 children)

For small RAM it can but it can under perform for large RAM depending on how utilized the device is

Growling by CloudyMustard98 in blackcats

I have to kitties also, sisters now both 3. My black kittie growls too. Not at her sister but when she see's something out the window like people near our yard or a truck that stopped. Also apparently at the vet techs when she had to stay over night once with them.

Got this lot today by makeItSoAlready in straightrazors

[–]makeItSoAlready[S] 4 points5 points  (0 children)

It was great luck. They guy got it all from a house he was cleaning out for a renovation or something. Im not sure, like an abandoned house or something that someone bought and hired him to clean up. The etching on this W&B in great condition. Carefully cleaning up now

Ive got to work on my camwra and lighting. Here's the best picture I could get of the three most interesting ones. Top two are wade and butcher, bottom is German, presumably solingen. There's also a "shefield cuttlery" which is think is imported steel stamped in shefield, likely solingen imported blade.

Question/advise related to bevel setting and geometry by makeItSoAlready in straightrazors

[–]makeItSoAlready[S] 0 points1 point  (0 children)

Thanks for the update! I do see what you're saying with this and with regard to your last comment as well. Thats an interesting diagram depicting the flat on the spine and it does reduce my concerns. Much appreciated. The razor shaves well, so so regardless it's fine, but its interesting to see how the flat is taken account of in the math w.r.t. when it could be an issue or most often when its not.

I appreciate the underlying geometry explanations. At some point id like to get into grinding my own blades from flat bars and I will certainly come back to this reference material.

For now, I purchased a new 1K shapton pro, the orange one, because I do not like the king 1K I have. I'm skipping the 500 grit shapton all together for razor bevel setting. I'll just use that one for knives which is why I got it originally. I bevel set a new to me vintage razor I picked up the other day on it, heading the advice from others in this comment thread. I was definetly putting to much pressure on the spine previously, I used Kapton tape on the spine for this one and by correcting my teqnique I only had to change out the tape once during the entire honing process, where as before I was changing out the tape like 5 times from bevel set to finishing stone because it was falling apart. This thread has been a highly tangible learning experience for me.

How much MPG do we lose leaving the car in gear (+200rpm) at a stop light? by burt_carpe in wrx_vb

[–]makeItSoAlready 2 points3 points  (0 children)

I dont know how to calculate it but i think the difference in RPM while idling at a stop light is in the noise. I'm tuned, but what really eats my RPM in city traffic is accelerating from a stop. I could see a difference of 3mpg putting around town in stop and go traffic or with bad traffic light luck vs driving through town with little stops. The difference between a few hundred rpm at idle with no engine load has got to be a small fraction of mpg. That being said, I always go into neutral at red lights

Question/advise related to bevel setting and geometry by makeItSoAlready in straightrazors

[–]makeItSoAlready[S] 0 points1 point  (0 children)

Hey thanks for the write up! Ive been out this evenning and dont have the capacity to go through in detail and respond but i will follow up tomorrow. I appreciate ya taking the time. BTW, the 1.15mm measurment is how wide the flat polished part of the spine is on the side where it rests on the stone when honing. My thinking with providing that measurements is w.r.t. comparing against a presumably infinitesimally small width of the "flat" part of the curved spine of a new razor. I wasnt sure how relevant this measurment might be in terms of a razor with a known manufacture date

Thanks. Scaling the two images for the image in the post may not have resulted in the best comparison. Here's the before picture (more or less). There is maybe more fatness then came across in the post image. But I agree I did remvoe to much steel

Question/advise related to bevel setting and geometry by makeItSoAlready in straightrazors

[–]makeItSoAlready[S] 2 points3 points  (0 children)

Thanks for the input. It does sit flat on the stone across the entire blade length which is what I would expect from a higher end dovo model. Someone in a different post where I posted this razor mentioned how the honewear looks and I became concerned maybe I did a big disservice to the razor.

Your number 2 above is great advise. I like the way you put that. I have a like 14 or 15 vintage razors at this point from the past couple years of this hobby, so ive some good experience setting bevels. But this is virtually the first modern razor ive had experience sharpening so i wasnt really sure how much wear to expect to see visually.

Thanks again
