Jesus, my home network is just a Cisco 2900 with gigabit interface that I set up to let me use silly hostnames for all my computers i like it because I can set up TFTP and boot my Unix workstations over the network when I set them up It also routes DECnet to my VAX

my network used to be a router but I had to add a slightly smart switch to reserve bandwidth for one device that would freak out if it started running even slightly slow

my home network is a router and the various switches used to get ethernet cables where I need them. I run an unraid box to ingest and store hd video footage so I can edit in premiere directly on the unraid share without needing to shuffle data around or use proxies it’s surprising how fast a bunch of raided laptop drives will move data, it will saturate a gigabit Ethernet link that’s as complex as it gets for me tho Beve Stuscemi fucked around with this message at 16:16 on Apr 20, 2020 |

my home network is a cheap ubiquiti edgerouter X except I have one of these switches next to it https://www.aliexpress.com/item/32973985173.html so everything runs over fiber also an outdoor PoE switch powering my raspberry pi radio receivers thats also fiber-fed

Whats the best bet for an Arduino-like device (basically a shitload of GPIO) for someone who potentially wants to take their project commercial? I know from glancing at the Arduino licensing that I'd have to open-source parts of the project and ~MY IP~, also an arduino makes it really easy for someone to dump the firmware out of the device, obviously. I need something that has Arduino functionality without the hindrances to commercializing

I've never done it, but from reading stuff online, getting an ATMega2560 (the microcontroller used in the Arduino Mega with plenty of IO) and making a PCB shouldn't be that hard. Printing PCBs in China is dirt cheap now (with sites like jlcpcb) and fast. If you're really going for a commercial application of 10-100 products it would probably be the best option in my opinion. e: you'd basically need an AVR programmer to connect to the jtag port to flash the firmware. Dumping the firmware is going to be easy no matter what for anyone who knows what they're doing. I guess not putting a USB port on it makes it a little harder for the average dude with a laptop but there's not much more you can do, I think. go play outside Skyler fucked around with this message at 23:03 on Apr 21, 2020 |

if you're really worried about toeing the line for the open-source licenses and not using any arduino stuff, you're gonna have to write a shitload of code yourself. that's what i would be most concerned about. the hardware part is relatively easy -- ATMegas usually only need a couple of capacitors and a stable 5v supply to run, and you can program it with a $3 USBasp from ebay. or you could just develop it all on an arduino, pry the chip out of the board and plug it into your own circuit, and tell the open source people to go pound sand. nerds

and if you're seriously concerned about people dumping and hacking your firmware, well, handling that is probably out of idiot spare time project scope. you can't get code off the microcontroller, just the raw binary, so any attacker is going to be set up with decompiling tools and a deep knowledge of low-level programming and uh good luck

I’m mostly in the brainstorming phase now, but I know the last time I went down the idiot project path the arduino licensing was a problem. I’ll probably proof of concept it in arduino anyway since I have to find out if it even works and that’s just the easiest thing to try.

i'd be really surprised if given the final arduino product it took much effort to create a perfectly sufficient shim on top of whatever atmel provides. this sort of stuff is mostly complicated by generality, which is, presumably, irrelevant to your needs.

while i'm waiting for my last project to get manufactured, i tried making a development board that is very small but still usable and cheap to make. this is the result: it's based around the stm32g030, a 64mhz cortex M0+ with 8k sram and 64k flash. the pin headers expose 2x I2C, 2x UART, SPI, multiple 2msps 12-bit ADCs and up to 14 gpios. i added an 8-bit DAC and 2 megabytes of spi flash to make it more useful out of the box. also two buttons and leds for tinkering. can be powered over usb or directly from a li-ion battery costs less than 10 dollars to make even in tiny quantities, which is less than many of the ICs on the boards i typically make

I like the variant where you redirect all the requests through a transparent proxy, then your imagination is the only limit. you could make every image on a page hello.jpg if you want http://www.ex-parrot.com/pete/upside-down-ternet.html i guess it doesn't work as well now that HTTPS is more or less standard everywhere

gave the SSL-VPN web login page on my firewall the 219.css treatment (greenpos supremacy):  annoying part was having to replace the spaces and line-breaks in the ASCII art with HTML escape characters because the fortigate strips them out. also there's some JS which gets injected and changes the inner-HTML of the form elements so the NICE! is replaced with Login. can't seem to modify that, guess it makes sense to prevent trickery it's pretty cool how much you can customise these replacement message pages. also yes vpn.darkstar1.net is on the internet but i've configured it to only accept connections from sources that are geoip matched to AU so you'll need to fire-up your own VPN before loading hacking tools heh edit: yeah i'm too lazy to get a certificate. was thinking of hacking something together that uses let's encrypt, might be cool

I have a new idiot spare time project. a friend of mine who is a quadriplegic approached me about setting up a sim racing rig. he has limited mobility in his hands and arms but does drive a (real, non-sim) vehicle. he uses a suicide knob to steer, which is easy enough to replicate on any sim racing wheel, but the project part of this is he uses a two way sort of joystick to manage the brake and gas in his vehicle. he managed to snag a used one and asked me to try to convert it to work on a PC for iracing. so here is what I have:  it seems very simple. the lever is attached to that black thing that I think is a rotary encoder, but it has like 9 wires coming out of it, which is more than I’ve ever seen on an encoder. the encoder wires then run to that pcb which mainly seems to be a breakout and power board, it has an rj45 jack on it and a barrel plug more wires run out of that pcb and go into the braided line, which is cut.  the good part is there is no logic on the pcb, just power, resistors and the rj45. ill grab some better pics of everything in a bit. anyone ever seen an encoder with that many outputs? I’m assuming power, ground and some signaling but I’m not sure what else it could have.

ok i found the actual device. you probably already have this info since you have the actual hardware but i feel proud of my detective work. Eletronic Mobility Controls AEVIT 2.0 L-Series gas and brake lever the little notch thing on the lever is the same in this picture, and those two bolts below the encoder are there too  here's a pdf manual for the whole drive-by-wire system it's designed to interface with Glorgnole fucked around with this message at 06:00 on May 15, 2020 |

I would have expected some kind of encoder too, but looks like its actually just 3 potentiometers in a housing. Took me forever to figure out what SS&C stood for, since there's some loving financial investment group making GBS threads up all the results, but check out this PDF: http://www.mantech.co.za/datasheets/products/6015_spectrum.pdf Ctrl-F for "6111" series and you can see the exploded view. And more wild conjecture about the meaning of the rest of the model number 6111-2006-030: - 20 means 20KOhm pots - 06 maybe a shaft diameter designation? - 030 means 30 degrees of rotation (in each direction?) Also here's the product page but no additional info: https://www.te.com/usa-en/product-6111-2006-030.html?q=6111-2006&source=header maybe datasheet is request-able? peepsalot fucked around with this message at 06:50 on May 15, 2020 |
