You need to choose a scale factor (V/Hz) and a maximum frequency (Fmax)
Lets assume the following:
Vcc: 12V
Scale factor: 10mV/Hz (60Hz = 0.6V)
Fmax = 600Hz (6V)
Fmax = I2/(C1 x Vcc)

I don't know if your pails have a 1-1/8" - 12 spout but you could transfer to HDPE containers - would also allow you to see the amount of oil left.

The TIP121 is a darlington, so there are two diode drops in the base.
R = (Vin - 1.4)/Ib
Where
Vin = parrallel port outout (4.8v)
Ib = desired base current ( 10mA is fine for your...
More info is needed
Output for the transducer - What do you mean by serial pulse? Do you need to measure pulse width or frequency to get the distance? What are the timings?

If you use only half the bridge, each device dissipates half the power - can be less expensive to use two smaller parts than one large part.
bridge is a 200 volt 35 amp part - $2.76

The jaws on the 5 inch hit the bed before it can open far enough to hold a much larger part than the 4".
Go with the 4" 4-jaw independant - I have it and it is a lot heavier than the stock 3"...
If the relay was an automotive relay it may not have been rated to switch a 120 volt load.
Also, simply adding a diode across the relay coil will slow the release down - to the point it could...

Understood - tradeoffs are king.
You had mentioned a discovery with mid-band resonance - how goes that battle? Can you say anything or is it a patentable discovery?

For the bleeder pick either the power level or bleed down time to calculate the rest.
I would pick a bleed down time of 5 minutes and label the equipment to allow 20 minutes after power down...
Take a look at this link - the author makes his own 60° dovetail cutter to make AXA toolholders.

What about using discretes?

It's a full pack - fully isolated

At 4 amps average the dissipation would be less than 2 watts each with switching...
Have you used one of the free motor sizing programs to get a ball park figure for the torque needed to run your machine?
Once you have a good idea of the average torque, use the torque constant of...
Use the strobe line on the B&B as the sprocket signal.
You will also need to feed the strobe line back to the acknowledge line in order to get the next byte. A simple RC delay may be fine - 470...
The 5 to 10.5 is easy - a 74HCT04 to a 74HCT06 with a 470 ohm pull up to the desired voltage (or 12 volts with two diodes in series)
I would need more info on the sprocket signal - Does it need to...

You can't use the 205 oz-in max - it is a peak rating that can be used for a short time at low duty cycle.
The difference between servo's and steppers is speed. A stepper motor looses torque...
A local electrical supply should be able to get you 100' spool of some good 22AWG multi conductor wire for around $.75/ft. Try to get 19/34 stranded for flexibility if possible and a cable rated for...
HDPE in 6" is about $64/ft at McMaster
If UHMW is enough that's even cheaper

Use an AD597 to interface the thermocouple - datasheet gives a reference circuit.

A simple power supply (bridge + capacitor) can't react any faster than the line - if the transformer output voltage is less than the output voltage plus diode drops, the capacitor is not being...
If you don't need to turn the periphery, then the 7x12 will do what you need but you will have get imaginative to hold the stock.

A block of steel would work as an angle plate if you have the right size.
I looked into doing this but found the X1 micro mill on sale for ~$230. Now that the X1 is pushing $300, the X2 from...
Two reasons
#1 - cost: the drives do not need a regulated supply and at the power level involved regulated supplies get expensive. The drives are there to regulate the power supplied to the motor...

Aluminum wants speed - 350-400 feet/min, so for a 12mm drill that works out to ~2800 RPM. Obviously this is higher than you would want to go for most work but crank up the RPM to help out if...
I have a 7x12 and have turned some 6"+ parts from cold rolled steel (1.5" thick). This is not something I would want to do all the time. This was done with the parts on an arbor because my 4" chuck...

You could use a simple transimpedance amp but will run into issues as temps change.
