Mister Sinewave posted:I had a diode between the power supply output and the battery's + terminal so that the battery can never "charge" the power supply (I don't want current trying to flow backwards into the power supply when it's off but the battery is charged, or the battery is a higher voltage than the power supply can put out at the moment or whatever) echi, is ebay really not coming up with anything like server power supplies at the level you need?

Triglav posted:are you gettin a cool rack chassis or are you building a tower or what. i wanna turn my spare closet into a baby datacenter cuz i have too much time naw, not making a baby data center. this is my first server so it's most likely going to be in a tower that lives in the garage in the meantime. if the entire thing goes successfully, i'll make a more dedicated machine for vm's for network pentesting.

on another note - i am thinking of getting some hands on stuff for raspberry pi but i can't find myself a decent project that's useful to work on. i've been at the raspberry pi thread but has come up with moot. anyone here worked on a raspberry pi that did something OUTSIDE of a gameboy/emulator system or home automation/security system?

so if i want to program or debug an attiny261a i have to buy an atatmel-ice and run debugwire right? annoying mcu lack of feature: can't run both timers off a low speed external crystal while clocking the core and SPI off the internal RC osc as far as i can tell

I wanted to make something clever since I first saw the yellow drum machine video. took me like a year before I had a decent enough idea to start ordering parts. now that idea is like #4 on my list because I came up with others that were less ambitious but still interesting enough. dumb idea from this morning: a modern sundial with a prehensile arm that adjusts to project a shadow of hour and minute hands on a circle at its base.

Been working on this: It looks like dots on a grid, but I am trying to develop a multi-scale simulation platform that is engineered that can allow me to design complex simulations of all sorts of things. In this case I am trying to simulate neurons . The goal is to allow for simulations that depend on a variety of algorithms that need to work together towards a purpose. Each one of those dots on the grid is supposedly a neuron. It is far from complete, but I am plodding along steadily.

Doc Block posted:does adafruit's USBtinyISP work with those? looks like it might, turns out DW is a debug interface only and i need an SPI programmer as well to make it actually useful. but figuring out how to actually wire the SPI interface is a pain in the rear end, i think i've got it down by wiring it to the MOSI, MISO and SCL lines on the MCU, but there's also two sets of SPI outputs (one seems to be a programming interface and the other is a USI 3/4-wire interface) their app note on SPI flashing also lists series resistors to isolate the SPI from other slave devices that might be active during programming, but no values are given, it doesn't matter since i can use the USI SPIs for my slave device but this is annoying

ok bros Thabks: I guess I won't be producing maximum bass every second and a car battery should smooth the load  it's a dual voice coil sub running at 2 ohm and the amp is a decent mother fucker: the car it lived in has ended it's life

im coding an editor so i can make a game so i can make game assets, which is how this got started —scope crope— i couldn't really program at the beginning of this project and had never touched javascript; i did make a little game in flash ten years ago that's about it. so now im having fun learning to program and solving problems and im calling it recreational coding and i've painted about three things since i started so good job me coming up with a thing to make game art for and getting lost in code the game is 2d and it's all webgl (editor too) and im working with the incredibly cool phaser and here are a few of the things it does so far  - every object can have its own parallax value (i feel like uli writing this) - creates scenery (ie colliders, textured meshes) from control polygons with automatic skinning and adjustable spline subdivision http://i.imgur.com/Pk1xUAO.gif - but it can also do just regular sprites and stuff - uses dragonbones character animations (authorable in flash) - lighting with ambience + point lights + polygonal lights and a kind of painterly specular/normal hybrid that's difficult to explain because i don't have the vocabulary but it can look like a bunch of things and i like it - the editor is pretty free-form and organic with only minimal GUI, deliberately so because im hoping that that will help me make a less technical or grid-based game - im using dat.GUI to handle what little parameter-twiddling GUI there is which in retrospect may have been a little too simplistic for what it turns out i may need but on the other hand it's been great at forcing me to come up with more intuitive solutions for things it can't do with it and those have been good so far and also interesting problems - one of the most difficult things so far has actually been setting up the whole camera, zoom, focus, pan, parallaxing code but since i've sorted that out it's been a pleasure to work with so im fairly proud of that here's an ingame gif with placeholder art that i made: http://gfycat.com/BraveIllfatedElephant i know that i will eventually have to rewrite the whole move/collision separation code but im actually looking forward to that this is a moodier shot with a few lights, a few objects at different parallax levels and some fake fog. you can kinda see the way the specular lighting works in the legs of the figure, the way it makes them appear shiny. again all the art is temporary (the grass texture is from rayman but i made the rest): http://gfycat.com/BleakSimilarInvisiblerail excuse the choppy scrolling, i was using the mouse to move the camera around the world so yeah thats my project!

not too bad, as long as you can supply ~180V the actual switching is pretty easy. there are ttl chips made specially for it (7441,7441A,74141) but they tend to sell for silly ebay prices. check this out: https://web.jfet.org/nixie-1/NixieTransistors.pdf

nixies are cool and all, but pretty inconvenient to use. good thing about them is the surprisingly long life spam (100k hours typical for the siemens tubes in my HF transmitter) IV-11 VFD tubes are cooler IMO, great visibility and a more convenient drive voltage  this summer i got a box with about 100 LED numitron replacement "tubes", routed the PCB last weekend to make a simple clock with them using the timecode/PPS output on my GPS timing receiver as a time source
