If I had a 0 to 5.0 Volt ADC Input I would just use a 50:1 divider or simply use a 10K resistor between my 40 or50 VOLT INPUT AND TAKE THE WIPER OUT TO MY adc. sIMILAR TO THE BELOW IMAGES. tHE SENSED VOLTAGE IS 0 TO 50 vdc, The scaled voltage to the PICAXE ADC now becomes 0 to 50 Volts = 0 to %...

The pictured circuit is a basic voltage doubler circuit. With a 250 VAC output from the transformer here is what you will get: Capacitor C1 is charged through D1 on the positive half cycles. C1 will charge to 1.414 times the input voltage of the input or 1.414 X 250 Volts = 353.5 Volts. C2 is...

Reading the article he does mention he used a forward current for the string of 46 mA. All four IR emitters are in series. Running with 50mA I would configure the LEDs as follows: You would be running the 4 LEDs in two series pairs off 5 volts with a total current of 100 mA for all four IR...

My thoughts and my thoughts only. You can build a chronograph as in the original post, a chronograph will give you projectile velocity which is what it is designed to do. A chronograph will consist of two sensors also known as screens or sky screens in ballistic chronographs. The chronograph...

I agree and see it as a really cool project. Heck, you are working with a short distance which is great. The following may be of some help. Working the screens will be tricky. Also if you do the screens and work the Velocity = Distance / Time formula just keep in mind the screen spacing gets...

OK, I cobbled something together that pretty much covers how I would go about doing this. I think it comes real close to what you want. Earlier I mentioned using a DATAQ basic data acquisition starter kit I linked to. That inexpensive little unit should do what you want to do. The units include...

I am trying to get data from a PICAXE 08M2 into a PC using VB6. I also have VB.NET if it matters but prefer VB6. I am not a programmer type and on a scale of 1 to 10 (10 being really, really good) I come in around a minus 3. Any help would be most appreciated. So here is what I have for my...

This I believe is my very first post and I am new to the Picaxe family of chips. I will try to explain what I am trying to do. Here is my code so far: main: if pin3 = 0 then UnLock goto main UnLock: for b0 = 0 to 0 if pin3 = 1 Then Exit high 4 pause 200 low 4 pause 500 next b0 pause...
