How you approach this depends, of course, on who your adversary is and how valuable the information would be to them. Is your adversary the Mossad, or your neighbor's kid? Storing nuclear launch codes clearly requires a different level of protection than storing the password for your lawn sprinkler automation system :) Cutting the programming pins will only ...

This can be done by pipelining. A sample is taken at each clock cycle and retained for long enough for all the approximation steps to complete, Meanwhile the more samples and other approximations are being done in parallel https://www.maximintegrated.com/en/app-notes/index.mvp/id/1023

Having used commercial circuits and built a few myself... The standard model rocket igniter takes a fairly hefty current to work. In the olden days, an incandescent bulb was placed ACROSS the launch button. In the modern era, an LED and resistor can be in the same place. The igniter will not ignite (and if, somehow, it did, it would only do so when you ...

All excellent suggestions; Here is a further refinement. This circuit keeps the leads shorted until just before firing to prevent unattended launch through an ESD event. You'd use a DPST (Double Pole Single Throw switch with momentary contact. Don't for get to fuse the system, no need to melt every thing.

simulate this circuit – Schematic created using CircuitLab Figure 1. Power-on indicator and buzzer additions. Simply add them in parallel as shown. BTW, congratulations on an excellent first post with correctly drawn and oriented schematic. simulate this circuit Figure 2. Time-delay function. As Wouter suggests, a time-delay adds ...

My suggestion: use the on/off key to power a circuit that consist of the buzzer and a 555 that is wired for a delayed output. The delayed output powers a LED (to indicate to you that you can launch) and the launch butten and igniter. (You might need a power transistor or relay, depending on the curerent required by the igniter.)

1) Yes. Go back to your original goal of determining optimum fix interval. How is having ten 32-bit ADC in parallel vs. one 24-bit ADC going to affect your decision. Is your fix time in nano, micro or milliseconds? Most likely you don't need such ADC precision to get the optimal solution. 2) Yes. same as question 1. Look at the ADC you selected, at the ...

It is a photodiode to measure the light reflected from the particles.

Tangible differences could be: Ceramic capacitors have lower ESR and due to this they offer lower leak currents than the electrolytic capacitors. tip: Try to use ceramic capacitors to your battery-powered designs. Lowe ESR also means that ceramic capacitors have better transients response so they can provide current (more easily) during a transient. ...

'Andy aka' has stated the best answer. Adding any kind of filter to the final driver stage will be pointless, as the coil and cap values are chosen to be resonant at 13.56kHz. If these L and C values are resonant at 13.56kHz, then they will oscillate at exactly 13.56kHz (ignoring parasitics) and thus, give you the most optimal power transfer. The Q, ...

1. Capacitors There are a lot of misconceptions about capacitors, so I wanted to briefly clarify what capacitance is and what capacitors do. Capacitance measures how much energy will be stored in the electric field generated between two different points for a given difference of potential. This is why capacitance is often called the 'dual' of inductance. ...

The obvious difference is that electrolytics are much bigger than ceramics. 1mm by 0.5mm ceramics are common garden variety, your electrolytic cans are far larger. Then, as others have pointed out already, electrolytics do not do that well in high frequencies so they're not suitable for bypassing "high" frequencies, it can't keep up with 1MHz chip, let ...

For example, why do I see it suggested to use ceramic caps for power decoupling per microprocessor & a larger electrolytic capacitor per board? why not use electrolytic all around? The three main types have differing characteristics - I suggest you do some research on them but the main things to look for are self-resonant frequency (brought ...

There are many factors that would influence the decision of which type of capacitor to use in any given instance. Here are a few: Cost is a factor. A given application will require a certain set of specs such as capacity and cost to attain that will guide the decision. Performance requirements. It will be desired to meet certain goals such as transient ...

Yes, you can definitely do that. After all, the whole point of having a soft-core CPU is so that you can integrate it with custom logic. At its heart, the NIOS processor is just another HDL module. You can instantiate it within a top-level design just like any other module. However, I have found that the vendor tools (from both Altera and Xilinx) have ...

Well, the power draw will be pretty dependent on how much power you're dumping into your load, varying the supply voltage would be a pretty simple way of regulating the power output of a resonant circuit.
