   gettin somewhere, middle pic has the amplifier & 100k volume pot (lol 64 turns) because no one nearby has any tiny non-linear trim pots like i want, however the OLED screen just barfs noise all over the power and ground causing the worst screech, i dunno if i have time to isolate it so i might be stuck with a screechy power situation  shout out to my boy jonny290 for being patient with me and some dumb questions i had

So for Rocket Rover 1.1 I'm changing the background color from that awful cyan-ish to pretty cornflower blue  Ugly cyan Cornflower blue Magical. Revolutionary. Gotta wait until Apple reviews & approves 1.0 first, though. Doc Block fucked around with this message at 09:10 on Aug 29, 2014 |

Gotta work some kind of fight club reference into the 1.1 update notes because the background in the icon is gonna be cornflower blue too.

i finally got off my rear end and built the interface board for my UHF receiver i only have single supplies so a used an opamp to make a virtual ground with two large tantalums and some diodes to prevent them from reversing on me, then I used that to build a second order 5 kHz linear phase low pass filter with a voltage gain of 20. this filters out-of-band noise from the discriminator signal and provides plenty of signal to the modem, TIs filter software is good for this sort of thing, even tells you how fast the opamp needs to be and phase/freq/group delay graphs it's a quad package, I used the other two to provide a balanced output from the modem to the transmitter, I don't want any single ended signals going between the two devices for RFI reasons, and this works nicely with a single stereo audio jack, both signals are 50 ohm source terminated and i put in some 100nF filter caps just in case, the receiver will be a high impedance difference amplifier with good common-mode performance, and maybe i'll stick some ferrites on there just for a laugh the PTT signal is connected to an optoisolator for the same reason, the transmitter is in all likelihood designed to be pulled down so the opto is perfect there's room on there for a RS-422 interface if I want to link the two devices, so that's all good then

i was inspired by your pics, it was kind of relaxing to wire up AF circuitry again, nothing really matters since FM only gets around 30-40 dB SNR at the best of times here's something actually RF related:  inside a NMT-450 mobile phone duplexer, this is two sets of 4 helical filters providing a band-pass/high-pass and a band-stop/low-pass, this lets the phone send and transmit at the same time tuning was done at the factory in finland with those metal brackets, the lid detunes all the cans by the same amount so tuning can be done with the lid off with some experimentation. the assembly was soldered together and I desoldered it with a hammer and chisel the coils are silver coated to give high surface conductivity, this increases the Q factor of the filter, the shielding structure is solder-covered brass, and I soldered on some semi-rigid coax and SMA connectors to measure its performance  i soldered on some nuts to the top lid to tune it, and built a crude vice to hold it together (not shown) with some EMC shielding material wedged in between  here's how I tuned it, it works as a very high quality band-pass, approximately 5 MHz wide. we use 2 MHz split between TX/RX so this filter isn't suitable as a ham radio duplexer, this tuning covers the entire non-space 70cm band I can use and has 70-85 dB rejection of all frequencies outside that, at least from 200-1500 MHz i was able to get the insertion loss down to around 5 dB at the center for the final tuning so i might use it as a transmitter-filter if the base-station transmitters filters can't be retuned easily, the receiver already has filters that are almost as good so there's nothing to gain there.

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) the IC you're using is very consumer and has a lovely datasheet with no layout suggestions or troubleshooting tips like you'd expect in a TI/LTC version of the same basic IC here's a few things you could do: separate the ground wiring to the AF board; there's separate inputs so if the IC manufacturer intended it to be used with star grounding you could run a separate signal-reference/shield for the AF from the source this is kind of a lovely fix, star grounding is a holdover from tube amplifiers and is a really bad habit but sometimes it works, I have a feeling it might not help in this case as an aside, here's the deal with "signal ground" and "power ground" in anything remotely high power or high speed (ADCs, amplifiers): they're the same drat thing, the reason they're separate pins is because they need to avoid ground-bounce over the internal bonding wires in the IC connecting them separately may actually make things much worse. also, datasheets are frequenctly written by morons (looking at you, TI, ADI). put a differential conducted emissions filter between the OLED board and the AF board, what I actually mean is put a pi-filter in, a good low ESR electrolytic on the power-rail on the OLED board, some kind of inductor (~100µH-ish), then put a similar size cap on the AF board supply, this effectively means the AF AC current will be drawn from the AF board cap and the OLED AC current will be drawn from the OLED cap a low value resistor might work instead of an inductor, it's more linear with frequency but DC voltage drop often rules that out failing that, get something with less gain, I've got a pile of 5V class-D amplifier boards I bought on ebay that would be perfect for that application, they cost about $1 a piece there's a reason I build my poo poo over a solid piece of copper ground-plane, it ensures every ground connection is effectively zero ohms even at high frequencies, if you want to really get into high speed, read LTC application note 47 longview fucked around with this message at 19:46 on Aug 29, 2014 |

So Rocket Rover was approved by Apple and will be available for download on Tuesday. BUT BUT BUT If you act now you can grab one of these codes and get the game-like app entertainment software product RIGHT NOW Redeem one of these to get the game early. Or don't! XRW6NPXNHNWX KNE7EX4EN7N3 9EHRYX9EWP99 KHHPR6LMW7AH It requires iOS 7, but runs great on an iPhone 4 running (tested w/iPhone 4 running iOS 7.1), and it'll be free, so even poors with poorsphones can play.

But these sounds are greaaaaat  (ok) edit: pro tip: the canons shoot as soon as they get halfway on screen, and then every 1.1 seconds after that. your shots can take out canonfire, so either shoot the canon's shots and then shoot the canon, or stay above or below it until it fires & then get in there and blow it up. then you can fit through. edit: also, you get an achievement if you get at least 1 point and 100% of your shots hit either a canon or a canonball.

my current issue is that I really want to make my game upgradeable and take advantage of the object oriemtated nature but ie realised I've done a few things and now I have to start again with them. eg it's easy to make a level or pawn and make it work but you want a second pawn do you want to have to copy and paste all those same things in again? non of course not. but I having trouble with the component hierarchy and meshes and thrusters gently caress
