Do you have fond childhood memories of summer camp? For a chance at $250,000, campers must compete in a series of summer camp-themed challenges to prove that they are unbeatable, unhateable, and unbreakable. Host Chris Burns is joined by the multi-talented comedian Dana Moon to recap the first five episodes of season one of Battle Camp . Plus, Quori-Tyler (aka QT) joins the podcast to dish on the camp gossip, team dynamics, and the Watson to her Sherlock Holmes.

We are doing a 2025 listener survey ! Answer the survey and put in your email to win one of three Jumperless OG units donated by Kevin Cappuccio (past guest of the show ) Note: this was corrected from the original, these are not v5 units, they are the original Jumperless units. Apologies for the confusion ~CG Chris signed on to get solar installed He’ll be taking advantage of Duke Energy’s PowerPair , a program to get a bulk amount for the battery and ongoing payments to act as a virtual power plant. Telsa Powerwall 3 Teardown Australian politicians are proposing money for batteries for everyone in Australia Peter Walkinson batteries CATL batteries Back powering off a Chevy Bolt AC battery power Peaker plant Check out the rates for peak power in New South Wales (high!) Base load Chris is working on a new series for tiny hardware nRF52840 With careful planning, it’s possible to get a “0.4 mm pitch” (found out it’s actually 0.35 mm!) onto the JLC 6 layer process because they now allow via in pad. Jumperless v5 episode (though as a reminder, we’re giving away the OG versions, not the v5) Dave review of Jumperless (mailbag video) We are doing a 2025 listener survey and added some new questions Slow trigger R&S version Laminated cheat sheet Jeff Geerling Bosch video The Tariffs in the US are an absolute mess. Since recording they have been downgraded, but they are definitely still going to have some outsized influece on the electronics world. Chris thinks that it makes more sense to race to the bottom of available parts (like the new $0.10 CH572 with Bluetooth), pay the tariff, and put in more time and effort on the software. Not that Chris is the intended audience, but also that it’s not going to have the effect that is Ghostbusters song…

#687 – The RP2350 with the Raspberry Pi Team

14 weeks yang lalu

—

Welcome James Adams , Chris Boross , Liam Fraser , and Luke Wren ! The last time the RPi team was on the show was about the RP1 (#648) The order of parts being released was RP2040->RP1->RP2350 Check out the datasheet for the RP2350 Learning from silicon Security and power states The part is a “Dual dual core” The Arm side is a Dual M33 The RISC V side is a Hazard 3 processor , designed by Luke based on a previous processor called the Hazard 5 HB5 There is a mux on the core and you select which side you’re going to use at boot There are 48 GPIO (but users always want more) Chris Boross (first time on the show) is on the commercial team. He’s seing interesting applications for the RP2350 including devices that are using it for motor control. They also have seen the part used in satellites because mRAM or masked ROM is less susceptible to radiation errors The PIOs have changed, but are more evolutionary from the RP2040 The PIO allows you to create state machines that process inputs without processor interventions, basically like tiny cores 2 cores – 8 total Interesting PIO applications Luke still likes that DVI on 2040 that was discussed on the first episode they were on (#529) CAN is possible USB host / device MII / RMII ULPI – USB 2.0 Phy The core frequency only increased 133 MHz -> 150 MHz. There is tougher timing with the M33 LVT – lower voltage threshhold 30 -> 40 pins There are now variants listed on the RP2350 product page (but not in mass production) that include flash in the SOM package RP2040 was one power domain “Powerman” (and of course AVR Man ) Switched core AON – always on 32 kHz There is a C/C++ SDK that is the basis for other ports Security is a focus for the RP2350 Bootrom in every chip Secure boot M33 features – secure / non-secure RISC V PMP RCP – Redundancy Coprocessor Raspberry Pi had a challenge / bounty for getting the secret out of the RP2350 OTP with secure boot One of the few silicon companies doing this sort of thing in public Past guest Aedan Cullen was one of the hacks called “Hazardous threes”. He gave a talk about it at 38C3 Past guest Colin O’Flynn was also mentioned because collaboration around side channel attacks with the Chip Whisperer IOActive used a FIB – Fine Ion Beam – and passive voltage contrast to capture an impressive image of a decapped chip (see the RPi post ) “Never want to see ‘novel technique’ in an email” Improving the RP2350 silicon How do you decide what to fix/leave? Can it be changed in metal/vias? SIO spinlock not being fixed Chicken Bit Filler cells are reprogrammable and help with fixes It costs approximately $50K per layer to change (ostensibly because of the high costs of masks) ULA – uncommitted logic array Die shrink doesn’t seem to make sense Will keep making each chip as long as 40 nm fabs are around Thinking about the RP2040 The easiest way to get started is to use a Pico (RP2040) or a Pico 2 (RP2350). Both have connectivity options as well. Raspberry Pi is now a public company! Doesn’t change much other than the business scrutiny.…

Welcome Carl Bugeja ! Carl lives and works in Malta He got started with robotics at his university Carl recently announced he would be launching a new company The company is called Microbots and they will sell components and kits for building similar projects to what Carl shows on his channel BigHero6 reference https://microbots.io/products/flatflap Max PCB temp is 130C Driven by series resistance of coil Tg value of PCBs A circuit that can solder itself How hot can a Flex PCB get ? Batch vs raster Do you math? Tryng to get the perfect temperatures and dealing with flex materials Dealing with manufacturing differnces Scanning PCB Coils with X-Rays Sending PCB specs Incoming inspection and testing Testing boards with resistance Time flap produce User testing Drive circuits – How do you evaluate? Don’t build your own H Bridge Optimizing for size Is Carl looking for other features? Building libraries for driver Foldable 4 wheeled robot , an all one PCB ESP32-C3, connected to playstation remote Boston Dynamics uncanny valley Gathering on social Top down vs bottom up (start at the top) Prior to YouTube, Carl worked at a startup Drones – 2 prop Bluetooth tags Later he moved to the automotive industry Concept vehicles Software What’s in Malta? Building a remote electronics business Remote actuators on a PCB Microbots Flexar Driver Driving down the price per cell Similar to how they drove down the cost of LCD displays Pixel, voxel, moxel, maxel? Flipdots PCB Actuation Find Carl on YouTube and Instagram , and check out his work on the new Microbots site !…
