echinopsis posted:4960? 4690? anyway I think that's the one I got. a much nice processor: kinda wanna upgrade to 4790 i7 for those sweet hyperthreads and 100mhz jump but yeah that plus ssd and decent vid card is enough Yeah 4690 just typoed it Yeah I have a good SSD and a decent video card so I'm good for a while hardware wise now. I'm doing the 3rd person blueprint-based tutorial from the official unreal YouTube channel. One thing that impressed me a lot was the blend spaces, they basically seem like black magic and it's super cool Also I'm really looking forward to the marketplace since I'm not very good art wise, if there's reasonably priced stuff I think it'll be super fun to work with

I don't even know what blend spaces are. there are a handful of things I haven't wen touched yet, animation, particles, characters. I'm very into using/abusing the physics system to make my game run and the lock to axis in the physics works flawlessly so far

It's really smooth and I have no idea how it works

I think it's Essential C# that everyone agrees to be the good c# book. at least it's the one I got to read for a bit and it looked pretty great to me later check stuff like this: http://en.wikipedia.org/wiki/Object_pool_pattern this seems like the holy grail of game programming poo poo idk and also read about SOLID at least to get a better feeling about oop design and then break these rules anyway

it's not like a special version of c or a fancy compiler, it's a normal gcc cross compile linked against avr provided libc for all their semi hosting features and stuff with atmel studio* and debugger friendliness.

The Arduino "language" is just a little preprocessor that runs before AVR-GCC. It compiles as C++, not C, but it doesn't support all of C++, but only because AVR-GCC doesn't support all of C++. Having C++'s largeness on a MCU with a few kilobytes for code and a few kilobytes of RAM doesn't make a lot of sense.

longview posted:well, looking at the pictures it looks like you've got a severe lack of bypass capacitors on both the OLED and the AF board, a problem might be related to there being (seemingly) a bypass cap on the AF board, the AC current draw from the OLED system could be fed over the power and ground wiring to the AF board, voltage drop over the ground will couple directly to the input (and with that ridiculous gain it takes nothing at all) well it's all done, i put bypass caps on anything with a +5v and gnd and that helped a lot, running it outside of my office also gave it a lot less noise, im guessing there is a lot of electrical noise in our office from all the random gear we have doing weird poo poo everywhere. here's a dumb video showing the software in it's final hacked together form instagram.com/p/saxYjlQujr we tried to 3d print a case but i didn't really give us enough room to just cram everything in there without redoing a lot of wiring and soldering, so we scrapped that and made a hilarious cardboard box and covered it in adorable stickers there's a funny electrical problem though. we have a 9v battery going into a modified buck converter that has a pot on the feedback resistor thingamajig so that we could fine tune it to ~5 volts (input range is like 5-45volts, its overkill lol), but anyways we suspect that the buck converter and battery don't play nice when the circuit starts firing up and everything puts load on it. in a nutshell the loving thing takes literally 20 seconds to actually charge everything up enough to turn on (we suspect the 3 giant 300uf caps from a dead power supply might have high internal resistance and are just loving everything up lol) many laughs were had and the gift was well received despite its flaws edit: if i had more time i would have "done it right" and saved a ton of money and time by just spinning a quick board in diptrace or eagle and having oshpark do an order, seriously with a freescale k20 and some jtag headers a lot of this would fit onto afucking tiny board, then i'd just drop a boost converter on there and use AA's instead of a 9v or something a cyberpunk goose fucked around with this message at 22:51 on Sep 1, 2014 |

Yeah you'd want a couple of very low ESR tantalums to run a switcher off a 9V, there's probably a big voltage drop whenever it switches...

getting closer to a working repeater stack, transmitter now actually transmits a properly modulated signal the modulation is applied directly to the output carrier at 1/4 the output frequency, unfortunately the synths loops response is fast enough that it fights the modulator input. DV data contains a lot of 50 Hz components, the synth generates hum at that frequency due to phase shift in the loop i managed to slow it down enough that it won't completely destroy the waveform but i still have some work to do before it produces a perfectly clean signal without excess sidebands  proper instrumentation is important, I use a rubidium frequency standard to tune the timebase in the radios to less than 1 ppm, this is important for narrow band communications  the receiver still works, but that piece of poo poo soldering iron i keep at the kitchen table isn't properly grounded so i damaged the output driver in my reference oscillator when I soldered a wire that came loose, managed to fix it by adding a buffer amp in series currently i'm scratching my head at the interface to the transmitter, there's no obvious transmit-enable pin on the rear connector, I suspect it might be controlled by the logic board. at least i know it controls power by checking the output power after the filter using an analog feedback mechanism, the final PA is always powered and only works when it has 10W of exciter power going in, and the exciters power supply is turned on/off by a large PNP transistor on the exciter/AF board, so if I get that transistor powered it should start doing something schematics also suggest there's an interlock with the synth-lock indicator so it won't transmit if it's off frequency

wear cotton, grab poo poo by the ground plane when possible, touch earth ground connected surfaces when possible, pretty much fine altho if it is very dry weather you may wanna practice some protection esd garments n bracelets are only when it is required for some iso whatever the gently caress esd safe soldering irons are plausibly a good idea since theyre not particularly inconvenient or anything tho

When you're working with prototype boards with tens to hundreds of man-hours in them and proprietary ASICs, it really is worth wearing the wrist-strap, though. Consumer stuff that you can easily replace, whatever. I wouldn't go as far as to say that it never matters, but I don't care when I'm working on my hobbyist poo poo, besides using a decent iron and sometimes touching a grounded thing.

It's worth being more careful with 80s CMOS special snowflake ICs too... No input protection at all really.

i got a 60W dummy load in the mail today! it's very well shielded and nicely built here's the PA stage in the transmitter unit  there's no biasing of the transistors or preamp built in so it requires a bit of power to activate, the boards at either end seems to be some kind of balun or phase shifter network to combine the two PA boards to the antenna, the design is fairly broad band with a bit of trimming so I shouldn't need to do anything in there except re-tune with the trimmers e: i think they might be power combiners and possibly directional couplers, there's a high power 50 ohm resistor connected to one of the ports that might be to absorb reflected power I know what all the wires do except one, some kind of network at the input to the left is either a power level sniffer output OR a variable attenuator circuit to control the power output, but they might be controlling power at the exciter level instead of in the output driver, still haven't gotten the exciter to power up in any case the green and yellow wires are just there to measure the voltage drop across the 50mOhm supply resistor, they're routed to a big D connector on the front panel labelled "TEST" I did a few tests with a HT as a signal source, it starts to work around 2W in, and pulls around 30W from the 12V supply at 5W input after i trimmed those capacitors, exciter is 10-15W it's possible I've got it in low power mode (seems to be 10W but not sure) and the AGC is kicking in but I'm not so sure, adjusting the trimmers related to power did nothing to the power consumption good news is my coarse test where I compared the received signal from the dummy load before and after the output filters and they were basically the same, so I'm pretty sure it's a low-pass and not a narrow band pass like I was afraid of, still haven't bothered to reboot into linux to run the blade and get some actual measurements and no way I'm dragging the whole transmitter to work just to measure it longview fucked around with this message at 18:31 on Sep 4, 2014 |
