drummerdimitri, You won't be able to use any number anyone else posts IMO. There are just to many differences that can occur. That was my main point & finding. You have to have a standard to make one. Paint type, reflectivity, absorption, thickness, target size, there are just so many places for...

I really hate posting in your thread Toaster...............you have no idea! I have no personal connection with DTR, friends,or such. You might want to take a lesson in a little "tact".......... I know it's a lot of $ and it may be a dud, but pls try address it in a better presentation... You'll...

I have a SD card reader..was just thinking since I dumped the original email..... Heck, if I could get 100 for $1........look out gaybay.......hahaha

Another question............. Can you indicate the good diode we are after on the "other " sled "? I'll get it out..........lol.......I think I remember that the not wanted one is a flat red?

I got that as an email promo............ My guess they are going for a "bait & hook"...hoping ppl will order more than just that. I dumped the email....is there a min......on anything? Hey I can get 100 for $1 LMAO

I'm still wondering what is so hard abt the > than 5 rule....... I'm no rocket scientist......I didn't fail math or programming languages either. I'm at a quandary why to have it calculate the number when you can plug it in already rounded in your head or round the result in your head :thinking...

Really.................? Ok............. If Z = A.X and X < 5 then Z equals A.0 else Z = A + 1 There all in one line. Surely you can apply this to other decimals............ Hope you get an "A". Edit: Something tells me calculus isn't going well.......:crackup:

What's wrong with the "if it's greater than 5" rule? Use that on any number .....................

That's great jib77! That last board does looks nice. I looked at the CriCut myself as my daughter has one. :whistle: lol Can't say she was happy, but I tried doing a vinyl type peel & stick sheet. Not that accurate on the trace gaps. Maybe the sheet is trying to move a little? :thinking: I found...

You need tracking so you know when it arrives and to call. :crackup: Of course with USPS tracking it may be there for 2 days before it shows. It would be found , taken apart, ID'd and the person in jail before they knew it was delivered. If it does get lost and they set it off, we'll know where...

Why can't I get that lucky? This new run must be diff than the old. I liked the old better................

Notice how that one in the link has the 1/4" square switch? His switch is 1/4" x 1/8". The head cap probably is not connected to the brass module. It's abt 1/2" on back in the tube. If he had a 9mm x .5mm tap, he could make a puller by unscrewing the lens. Some are epoxied in, some are just a...

That looks like the New Wish type pointer. Most don't come apart easily. The end cap will come off, but hope you have a way to press the brass lens/diode holder out without trashing the driver board. You can't push the driver board. You'll need a tool that slides past it. Tapping it with a...

Mine arrived yesterday, but I didn't hear the horn blow. USPS! Rescued the hostage this morning from the Post Office. Pkg looks fine & I got the PEMK - M1X sled. Thanks for the GB qumefox. +1

So far mine is a no show. Doesn't concern me though. As rural as I live, it's not uncommon for it to take an extra day or 2 sometimes. Other times, I can be the 1st delivered. I can get a 1st class pkg in 3 days from FL, 3-4 from CA and 5 days if it's 2-3 states away. USPS.....go figure lol

LOL, that seems to be the conclusion with any use other than a comparator Jerry. One of those, "you can't get there from here". At some point if you want to try to use the readings, you have to have a known standard to calibrate it and then you still don't know the upper limits of accurate...

Good question dnar. I thought I had a light meter in my camera bag. Hmmm...maybe my daughter "borrowed" it. I was wondering if it could read a laser output without damaging the sensor or maybe even set in side a box to block ambient light with the inside box reflective so the laser would be the...

I thought abt that using a 635nm diode set to 30ma which should be 5mw. Since it can vary from the manufacturer tolerances, lens loss, meter, the target size thickness, paint, drafts, on and on... I can still see room for errors if calling it an actual number in power. Comparison in a % value, I...

Thanks Morgan. Glad you see it useful. Some have issues with linking calculators, but it helps newcomers to get the right values without asking and it shows ohms laws that they can learn. It's actually good for the LM1117 and most of the LM series when used for current regulation and it has a...

In picture 3, it should be soldered between the 2 parallel white lines. You should see 2 solder pads there and matching ones on the switch button back.
