content: Hi guys,For those of you more into software, this might interest you:The Unreal engine is up for licensing for 19 USD/month + 5%:https://www.unrealengine.com/When you actually sell your game/software you pay 5% of the revenue.This is a major change from the times when you paid an obscene amount (hundreds of thousands of USD) before actually getting access to any code or development stuff. The engine itself was used in a lot of top-of-the-line games and looks really great. For those of you looking into a impressive way to visualize your outputs (simulation, VR, design) or similar, this might be an interesting path to try.Enjoy,David

Kapton Polyimide Film Tape for HV Isolation - Page 1
Forum section: electronics / general

timestamp: May 30, 2014, 11:10:02 am
content: I have a PCB I designed that generates a ramp up HV charge of about 8-10K used in amino acid experiments. This is the prototype to a larger 50K design. The circuit charges until the small air gap between two wires causes a discharge resulting in an arc across them discharging the circuit and the whole process repeats. The charge build-up is roughly around a 10-15 second cycle. Problem is, it has recently been discharging through a resistor next to the HV capacitor even though I have increased the gap between these two components to almost twice the distance as the wire spark gap. Its strange that changing the material, meaning the discharge wires, to a more conductive material seems to have cause this issue. The only other change I did was disconnect my bleeder resistor, but the circuit had been working great up until this PCB arc issue. The bleeder resistor is not needed for normal operation, it was designed for safe discharge when the circuit was powered off. I removed it for development testing and measurement.So, getting to my point, I ordered some Kapton Polyimide Film tape which I am going to wrap these components to try and isolate this problem. Has anyone been successful in using Kapton Polimide Film for this?It's getting old replacing this resistor after these arcs, it pretty much blows a chunk out of the side of it when this occurs. What's puzzling, the circuit has been working fine and all indications appear to point to the change it discharge wires which makes no sense. These wires are more conductive than the older ones.

content: That's a lesson every micro newbie has to learn the hard way. I managed to reliably crash an Arduino with a mechanical rotary encoder by trying to use interrupts. If you twirled the knob fast enough, it would lock up and/or restart.That read-and-shift code works really well. I consider that the ideal software debounce method, although I do tend to use the dumb routine (sample, wait 50ms, sample again, compare) for minor hobby projects.

content: Seems a little 'extreme' to just state not to connect a switch to an interrupt pin. I do that on most of my designs, wakeup on interrupt or pin change (interrupt). Once awake I then disable further interrupts on that pin and transition to a timer driver interrupt routine that then samples and debounces the switch. Very easy to implement.So, yes, connecting a switch with bounce to an interrupt pin AND trying to use interrupts to detect switch status is not a good idea, but no reason to not use an interrupt pin as the wakeup source.I can safely say that with several 10's of thousands of shipped boards that this scheme works 'just fine'...cheers,george.

content: Hey, Nice find GEuser,I too was given a couple of old UHF radios from a friend of mine who has a truck wrecking yard.They are Motorola Syntrx radios and they are actually a commercial radio. I've programmed them up for the 40 UHF CB channels (not strictly legal as they're capable of 25W and the limit is 5W).They're a great radio but I've had to repair them a number of times, leaky caps and a blown audio output stage. Still have problems with the mic leads which get broken wires.How did you calculate the lengths for 1/4 wave antenna?Only thing which might be a concern is sitting so close to that antenna if you're transmitting for extended periods, maybe not a big deal at 5W.The other thing with old radios is they mostly don't have the 6.25khz channel spacing so you don't get access to the extra new 40channels.Cheers,Dean.

content: Hmm, if it's really as simple as the diagram indicates, they should be electrostatically biased and high impedance AC coupled in and out (on the order of 300kohms as stated). Very high impedance, very weak forces, but with a high Q resonance (rise time on the order of 1s for a few kHz suggests Q in the 1000s) that's all it takes.Should also be able to do frequency doubling at zero bias, and related multiplication / parametric stuff.Under bias, the response should roughly resemble two very small value capacitors coupling to an LC resonant tank with quite large L. Not quite analogous to a quartz crystal, but could be used for filtering (very narrow band, a few Hz at most) and oscillation purposes with the necessary circuit changes.Tim

I haven't seen the Kindle Fire TV in detail, but my experience with Kindle in my country was very inferior, as they don't really support most purchases. I assume you're in the US, so that shouldn't affect you. It's just that the Kindle fire I bought died on me after a year for no apparent reason. The touchscreen was acting funny from the beginning and one day it decided not to respond at all. I didn't like the software either. Apple seem to have solved all these issues even before bringing their stuff to market.Not being made by any dominant media stores, the Roku is the best bet, in my opinion. It seems more open and you can watch netflix on itAlso it actually supports channels, not necesarilly a video store. The Apple TV is basically pay per view, last time i checked. Unless you bought the movies, of course. But it gets expensive fast, specially when you have services like netflix.

This and the use of "test" crystals for "private" channels pretty much drove the FCC boys nuts. Now if you happen to need a "foot warmer" (linear) - Thomas E. Washington and Tech-Nine Technologies, could be just what you need. As to why some folks would rather use a CB and a linear, rather than a cell phone, I am clueless.--But if you like "bigger hammer", cost is no object, robust construction projects, I highly recommend you give Mr. Washington a view.

I'm working on calibrating it now, but it's proving finicky, I got it to stay at around 300, but when I turned it up the temp went down, so I'm still figuring it out. Is the heater perhaps dyeing out? There isn't much range on the trim pot.

content: I seem to be... collecting many components over the years of unfinished projects and prototyping etc.I'm looking for a very specific type of storage container. I think I may have seen dave with some similar.Basically you have a normal storage container... something like this.http://www.amazon.com/Akro-Mils-5905-Plastic-Storage-Hardware/dp/B000BQPZDK/ref=sr_1_16?ie=UTF8&qid=1400286469&sr=8-16&keywords=parts+organizerBut then those containers are themselves drawers in a rack. So you pull out the container then open it. I guess essentially you could consider it a rack with storage drawers that have lids on them. The nice ones are captive (meaning the drawers can't pull out all of the way), but the cheap plastic ones seem fine too. I'm not a huge fan of the typical bin style storage because if you EVER drop or bump that thing hard... everything is going to fall out.My actual question is, what are these types of storage called and where can I buy them?

With these, add in some foam inside the lid of each drawer unit, and the parts can't mix together.Edit:Durham Manufacturingis who actually makes the metal boxes. They also offer a line of plastic that will do what you want.

Stuff like a 100nF, 1K resistor, 10k, 100k, 10k trimpot... Apart from project specific stuff (like for example a DS1307 for a clock project), once after I grab the project specific stuff, 90-95% of the other stuff I need can be filled from my few near by small boxes as I experiment.

Some were red and some were green but they were not from the same manufacturer so they were pinned differently.Apparently on the red ones I got, Jameco sold two different matrices under the same part number with completely different pinouts. GRR. That wasted about 1.5 hours of my time today figuring out why it wasn't working right.I searched the part number CS-5704H and the first link was Octopart.http://octopart.com/cs-5704h-jameco+valuepro-22020638http://datasheet.octopart.com/CS-5704H-Jameco-Valuepro-datasheet-7283224.pdfI finally out of frustration I checked Jameco's site and found this datasheet, same part number, same Jameco stock numberhttp://www.jameco.com/Jameco/Products/ProdDS/218843.pdfAnd that had the correct pinout.Notice the datasheet listed on octpart is very crisp, but the datasheet on Jameco is blurry? Now I suppose someone could have modified the datasheet to be incorrect but it seems like a wasted effort.Both listed as Jameco part 218843 but one is column cathode and the other is column anode.

The vendor said some computers would not be able to give it enough current and it would stop working. My testing showed it only was using 360mA which is below the 500mA requirement for USB. But the problem didn't resolve itself until the vendor sent me an add-on power supply for it.

But MPLAB does not see the Pic.Fire up Pickit software by itself, PC can communicate with Pickit 2 (even ran firmware update for it fine)VDD and VPP/MCLR work fine in the troubleshooting, but PGC/PGC refuse to go high.Popped open the programmer, checked the 33Ohm resistors on output - all fine.Check the voltage on the output of the PIC18f2550 on pins 4 and 5 (which are related to PGC/PGD), they go up to about 2.5V, but I am not getting any output on the ICSP connector.The last time I tried another Stepper motor on the dev board, using this programmer, I did have something happen that messed up the darlington array, maybe it sent 12v back up the wrong end of the Programmers Pic.Anybody have this problem before?Is the approx 2.5v on the output pin right (Not using the 30khz square wave test, just using the option to pull high. But 0v on the ICSP pins for PGC/PGD.Guess it is time to sleep on it.BTW it is a DB-DP004 Ver3.4 Pickit2 CloneP
