    As I said, great project, nicely done, very informative. And I learned some thing here , I like the multiple by 4 and diving 100 😂

  • DIY Timber Model Garden Windmill

    Very nice, I made a light house similar to this , only suggestion I would make is to include US measurements, gets a bit daunting and some what disinterested in project when converting measurements. I personally like it and think you did a fantastic job describing everything, even work arounds as to how to make parts with simple hand tools. Great job

  • DIY SOIL MOISTURE SENSOR CHEAP YET  ACCURATE !

    I don't see why not, I have made bigger projects with a pic ,I no longer do that because I don't have access to a serial parallel port . I have a pic programmer I built years ago but modern day computers don't use that technology as much,loved playing with the PIC,

    Ok I think I figured this out using some math ,so if i multiply the number given by the fracture I should get the result .In my case I am reading between 997 and 1000 on the monitor that shows a 67% moisture given the math would calculate that it is reading a resistance. So If I am right then for me to monitor 40% the reading should be around 596.Still don't understand the equation given in the sketch. I understand it is giving percentage I just dont understand the formula as to how it is worked out on paper. percent = 2.718282 * 2.718282 * (.008985 * moistVal + 0.207762).I would greatly appriciate it if someone could help me with this ,Thanks

  • DIY SOIL MOISTURE SENSOR CHEAP YET  ACCURATE !

    So I made this project, easy project and instructions were easy to follow. I have Peach a tree that I growing from a seed .First one I actually got to sprout what I was hoping to do was to measure moisture content somewhat accurately and build from there. I have it measuring the moisture on a sponge as a test, what I am getting is a lot of deviations in my readings. As you can see I added an led for an output ,I would like it to maintain to a degree moisture from 21% to 40% . Also I am trying to understand the math so I can set the alarm values for possibly 3 led's to indicate wet, dry and ok .That in it's self should be easy to do if I could figure out the math or exactly what the numbers mean that show the percentage. Is it measuring resistance or voltage , it appears to be resista…

  • DIY Plant Moisture Sensor W/ Arduino

    I know you wrote this a few years ago but I am curious about the math here. When I create this project I get the green led to light and it is in air, I realize air has a humidity but just curious how I would check the math related to the percentages . In free air I get 1% reading on the monitor green led (pin2) lit.I would think that the blue led would be driven high but maybe I am not understand it correctly. Your math percent = 2.718282 * 2.718282 * (.008985 * moistVal + 0.207762);caculates the percentage of moisture, could you please step me through it, math is not a very strong subject for me. I assume that the first and second values are multiplied together and the second value would be the probe readings + a value divided into the first value to give you the result. Is this correct…

I am trying to grow a peach tree in my office from a seed, I have a plant so far and wanted to monitor the value of the soil,worked hard at getting this to even grow, all others died. I read that the soil moisture should be between 21% to 40%,this circuit could help me with my plant ,thanks.

  • PIR Sensor Tutorial - With or Without Arduino

    Tried this several times and could not get it to activate, thought I had a bad sensor but tried a different one and didn't work. I know its marked as D S G d would get vcc S- D13 and G would be ground, am I correct? Looked up this sensor and it has a FET which require a 47k resistor across D G as a load.

  • Ok so I never got past the facade , measurements not complete enough for me to work with .By the time I cut the first part out of cardboard 351mm x 500 mm and tried to figure out the rest of the measurements like where the ears started and the base , my dimensions did not work out. trying to start from the bottom and measure up to the 340mm dim . Just made it very difficult to lay out properly.Maybe its me but this was pretty confusing without a better layout or possible template. Looks great, just had too many problems with laying it out and ending up correctly.

  • LarryF24 commented on rbodell's instructable Homemade TV Antenna

    Yes I have done this in a crawl space and works quite well. Omnidirectional, not but it does a nice job of getting signals even in a crawl space. I also tried this it side around 25’ high, worked well there not much difference. I get a lot of wind so I opted for in crawl space. Not 100% sure if it would be considered omnidirectional but it could just be my location. My signals are with in 20 miles. Only issue I had was dissimulation of instruction. I mis read it and made a 26” diameter when it actually is a semi circle of that 26” diameter.

    So what did the second loop do if anything? Do you find this to be omnidirectional? What spacing did you use between the two ? Did you try one circle first then add a second to se if it made a difference?

  • I also posted this question , from what I can see ,there is not much of a list but I am planning on doing this soon so I will add one here for my adaptation of this. You basically can start with 4 - 2X12X10 pressure treated lumber and 2 - 2X12X12 pressure treated lumber for the outside box and it appears he used 6- 4"X4"X8' for the uprights.Not much detail ,too bad but for the most part you can make it any size you want which will determine the material list.He wanted the inside to be full size so he used from what it appears 3 4X8 sheets of exterior floor (advantec possibly wax side down).Depending on what you want for floor strength you could set your joist every 12' but he used conventional 16" spacing , if you wanted to use it to store a vehicle or something I would …

Again I will probably build some rendition of this and post my list if that helps.

    Ok ,this guy built something rather nice and shared it with all of us, so I get it about building codes, but lets just look at it for what it was intended, a simple share for someone that may want to creat this, again, nice project.

    Agreed

    1 x 2 strips I assume was was to leave a space to put the foam insulation on before the flooring was installed, great idea I would also want to use some 6 mil poly for moisture protection .

    Just saying here, that looks like a good idea and I plan to build one , but I have found if all you need is a single tv, a short piece of coax with about 8" of the jacket removed a pretty darn good signal , I ended up with 23 channels.

    Alright , I made 2 circles 26" with an additional 1" on each side, just a bit confused here , should I end up when assembled with a 52" diameter 26" radius?

  • Just a question here , can you just stack the blank chip on to the inserted programmed chip and then load a sketch? Would it harm the original one ,just wondering if it could be done that way.
