What do you do if you’re laying out a PCB, and you need to jump over a trace, but don’t want to use a via? The usual trick is using a zero Ohm resistor to make a bridge over a PCB trace. Zero Ohm resistors — otherwise known as ‘wire’ — are a handy tool for PCB designers who have backed themselves into a corner and don’t mind putting another reel on the pick and place machine. Here’s a new product from Keystone that is basically wire on a tape and reel. It’s designed to jump traces on a PCB where SMD zero ohm resistors and through-hole jumpers aren’t possible. I suppose you could also use it as a test point. They’re designed for high current applications, but before we get to that, let’s consider how much power is dissipated into a zero ohm resistor.
By the way, as of this writing, Mouser is showing 1,595 for Keystone’s 5100TR PCB jumpers in stock. They come on a reel of 1,000, and a full reel will cost you $280. This is significantly more expensive than any SMD zero ohm resistor, and it means someone bought four hundred of them. The electronic components industry is weird and you will never understand it.
There’s a new product from ODROID, and you want it. The ODROID-GO is a Game Boy and Sega Master System emulator running on an ESP-32, has a fantastic injection molded case, and looks phenomenal. You can buy it now for $32. Does this sound familiar? Yes, a few months ago, the PocketSprite was released. The PocketSprite is the tiniest Game Boy ever, and a project [Sprite_TM] introduced to the world at the 2016 Hackaday Superconference.
This week, the speaker schedules for two awesome cons were announced. The first is HOPE, at the Hotel Penn on July 20th. Highlights of this year? [Mitch Altman] is talking about DSP, [Chelsea Manning] will be on stage, someone is talking about HAARP (have fun with the conspiracy theorists), and someone is presenting an argument that [Snowden] is an ideological turd. The speaker schedule for DEF CON was also announced. The main takeaway: god bless the CFP board for reigning in all the blockchain talks, the Nintendo Switch was broken wide open this year, but there’s only a talk on the 3DS, and there’s more than enough talks on election hacking, even though that was a success of propaganda instead of balaclava-wearing hackers.
The C.H.I.P. is no more, or at least that’s the rumor we’re running with until we get some official confirmation. When it was introduced, the C.H.I.P. was a Linux system on a chip with complete register documentation. It appears the end of C.H.I.P. is upon us, but have no fear: there’s a community building the PocketC.H.I.P., or the C.H.I.PBeagle. It’s a single board computer based around the OSD3358 from Octavo, the same system found in the PocketBeagle. Source in KiCAD, and people are working on it. Thanks [smerrett79] for the tip.
