TEAS - Test Equipment Acquisition Syndrome
Dave did a video comparing high voltage probes liked the HVP70
CMRR is improved with wymmetry in the probe design
Chris has acquired an active load, the Siglent SDL1020X-E\
Plugging some active loads with constant resistance / power into power supplies will make them hiccup because of the control loops interacting.
Chris also got a new soldering station, the Thermaltronics TMT-2000S
The lower end series are 470 kHz power supplies, the higher end Thermaltronics and Metcal stations use 13.56 MHz
The Metcal, Pace, JBC, Thermaltronics designs all use cartridges that heat to the proper temperature (as opposed to an adjustable temp). Thermaltronics calls this the Curie Heat Technology.
Tip to grip is the distance from your fingers to the end of the soldering iron. A shorter distance means more control. Unless you hold it like in the stock photos.
Chris has been using Small Rig clamps that have 1/4-20 threaded ends to interface with 3D prints. All you need to do is put a 6 mm hole in your 3D print and the clamp screws in and holds quite well.
This is the STL file for 121 GW
Dave predicts bench meters will make a comeback. The Fluke 37 is an example of this concept.
Chris is trying out the new Digilent Analog Discovery Pro, which was kindly sent to him
We had former Digilent president Clint Cole on the show a few years back
Though we're the last to talk about it, Raspberry Pi released the Pico board based on their custom chip, the RP2040.
The board comes on a reel!
Eric Schlaepfer (@TubeTimeUS) explains the costs of making chips on twitter. This is (likely) why the RP2040 doesn't have any internal flash.
Hackaday explains the PIO on the RP2040, an interesting peripheral that allows local processing of external events on the I/O.
So wait...is the RP2040 not a microcontroller? Find out next week when Chris interviews the Raspberry Pi team!
We will also talk about why they decided to go custom. We have had many guests on in the past few months/years talking about custom chips and the cost of chipmaking.
- Mohamed Kassem
- Tim Ansell
- Brian Faith
What is the breakeven point?
Ladyada (Limor of adafruit) discusses the RP2040 and how they plan to integrate it into their projects as well
Pico board specification
Interested in learning assembly language? Check out this web based 6502 simulator called the tejotron
It was inspired by past guest Ben Eater
Beagle, SiFive and Seeed Studio are teaming up to create the BeagleV. This will be one of the first RISC V (sub $200) boards to run mainline Linux. It also has some pretty serious processing capabilities.
Chris and Dave discuss RISC V and how it's an open source ISA, not an open source chip design. Those also exist (such as past guest Claire Wolf's PicoRV design), but are not used on the BeagleV.
GM says they'll be all electric by 2035

Measuring Current with Matt Liberty Jan 25, 2021

Show notes

Welcome Matt Liberty, creator of the Joulescope!

The Joulescope solves the problem of measuring current with a high dynamic range.
There are very different sense resistors when measuring active current vs sleep current
Chris learned this when working on electrometers at Keithley.
The key thing is keeping the burden voltage low so it does not brown out low voltage systems
Chris is planning on using the Joulescope to measure the ABC board
Matt recommends starting with a power budget
It's also important to understand how to set up triggers for the joulescope, such as a GPIO
Joulescope sits in the middle of the device under test (DUT) and the power supply of the system.
The front panels can be swapped out. It comes with USB and binding posts by default.
Default view is multimeter view, but the real magic is looking at the power profile.
There are many pitfalls in low power electronics, such as backpowering a pin
Some people are using Joulescopes in opearations/deployment to test devices are performing as expected.
There is an open source Python library
Matt describes why some elements are open vs closed source
GPIB
LXI
Most traditional test equipment doese a capture and transfers the buffer (either to a computer or a screen)
The Joulescope and other headless equipment streams the data. This is similar to the HackRF (episode) and Saleae (episode).
Streaming vs Buffering
Isochronous timing
USB limitations means you cannot have too many Joulescopes that are plugged in to a single system.
Competition
- High end test equipment from Keysight
- uCurrent
- Current ranger
- Nano ranger
- Otii Arc
- Power Profiler 2 kit
This is a different way of working and might feel weird to people that grew up with knobs and dials
Matt's background is in consulting, mostly around firmware (though he does hardware and FPGAs)
A main task while consulting was working with the firmware to lower power, hence the desire to build the Joulescope
When hunting down current problems, Matt recommends "Divide and conquer". Other things to look at:
- Check voltages across resistors
- Pullups to VCC and not turning off power rails properly
- Backpowering pins via protection diodes
- Odd problems he has seen
  - Flux residue causing more leakage current than expected
  - Capacitor leakage (through the series resistance)
Matt was on Embedded.fm a couple of years ago
Lower power modes in STM32 clock tree
Matt's tactic for a simple low power system: "Turn everything on, do what you need, go back to sleep"
Matt has discussed struggles to get the product out in the world on the Consulting Forum.
Matt has been a solo consultant since 2011. He knows how to carve out consulting time, in this case his "client" was his own project.
But why develop a product?
Matt's Contract Manufacturer (CM) is 15 mins up the road
Matt has set up a test station at his CM and trained the technician who watches the devices that fail testing.
Parts on allocation
Lot size is still 500
Matt was recently on the Hello Blink show talking about hiring subcontractors. He has managed employees in the past at Hillcrest.
2 FPGAs internally, both of them Ice40 (but not using the open toolchain yet)
This is an isolated design, meaning you can safely plug it into your USB port and whatever is being tested is galvanically isolated.
Device side FPGA does math on the other side of the isolation barrier
The host side FPGA doesn't do as much
Device FPGA is there to be really responsive and to handle both ADCs in lockstep
Open source FPGA toos
Current model is the JS110, Matt is not sure on other models yet. He would like to focus on two models that try to go lower cost / higher performance (2 separate things)
CMRR
Possibly going to make a module that acts like a high current sensor
Supporting multiple versions of hardware
Matt's lab is all scripted using python
Buy a Joulescope for $799, more than 1/10th the price of a similar class of instrument.
Matt now has two distributors overseas, and is hoping to be part of the Digikey marketplace soon, to avoid needing to get on Approved Vendor Lists (AVLs) at large clients.

Why IoT Is Difficult with Jonathan Beri Jan 18, 2021

Show notes

Welcome Jonathan Beri, founder of Golioth!

Today’s episode is sponsored by Mouser Electronics, who are discussing RISC-V. Check out their page on resources about RISC-V and how you can purchase kits that include chips using the open source ISA and learn more about how they can benefit your project.

What makes IoT so hard? "It's a system of systems"
Commercial off the shelf (COTS) systems are whitelabeled hardware with custom firmware/software
We use a brief example of a forest fire sensor using the ABC board
Firmware and security models
AWS IoT vs Azure IoT platforms
Implications of choosing a cloud provider
Jon has a background in hardware
He started at Google working on Firebase. Later they attempted a "Firebase for Arduino" that did not pan out.
He then joined Nest shortly after the Google acquisition, working on the communications.
Procurement and planning was interesting for Nest, especially because they added sensors that weren't available to the user / firmware right away.
Thread is a protocol that creates mesh network on a wide range of radios
Every device can talk to one another
It uses 2.4 GHz and is built on top of 802.15.4
How do thread devices get back to the internet?
OpenThread runs on nrf52840
Tutorial on OpenThread
After Nest, Jon went to Particle and worked on embedded
OpenThread based
There were lots of adventures with early Cat-M1 on the Ublox R410B
Particle bought RedBear, a Chinese startup with a lot of RF knowledge
Hardware is designed by Mohit Bhoite, who has been on Embedded.fm and also is a circuit sculpture master
Jon's last job was at WeWork (RIP?)
He wanted to learn more on the cloud side of things.
There were a number of WeWork sites spread out over 600 buildings. Each of these has a physical security need (door locks, turnstiles, etc)
The challenge is that his team didn't own or have the ability to change the hardware
Wanted to build the experience
Proxy (startup)
Going towards solving some of these problems
Physical constraints
ABC board
Vertically integrated embedded platform
Particle B523
Hardware matters
Android Things, now depricated
Building scooters
Nest door lock with Yale
FreeRTOS with AWS
Who do you hire to do the "in-between" hardware and the web?
Reasons IoT products fail
IT cares about setup, managing it, integrating into business process
Enterprise cnversations and managing devices
Fleet management
Fleet stuff is normally for the business person
Golioth
Jon wrote about CoAP and how it works
Chris wishes there is a site like BuiltWith...but for IoT devices
Protocols are an arbitrage opportunity
Internet is now standard part of RTOSes
- Mongoose
- Contiki
- Riot OS
- NuttX
HALs (Hardware Abstraction Layers) or PALs (Platform Abstraction Layers)
"Where's the porting guide vs where's the hello world"

Open FPGA Toolchains and Machine Learning with Brian Faith of QuickLogic Jan 11, 2021

Show notes

Welcome Brian Faith, CEO of QuickLogic!

Past guest Tim Ansell introduced us to Brian, from their work together on the open toolchain.
They met at a tradeshow and Brian declined the first time, only to be convinced later.
QuickLogic IP licensing
Brian attended OR Conf in Bordeaux, where they were watching talks and excited by future growth of users of the open toolchain.
Resisted for a year
Brian started at QuickLogic during the "schematic era" (when FPGAs were designed using graphical schematic of logic blocks)
Previously their toolchain
- Worked with early versions of Synplicity, but later switched to using Mentor Graphics Precision
- There was no bundled simulator
- Proprietary Place and Route (P&R)
The new QuickLogic approach is Symbiflow
It's also about the software engineer
A community member ported NuttX to the platform
What did QuickLogic give up, in order to use the Symbiflow toolchain? They had to publish the spec of the bitstream
What could you do with the spec of the bitstream? Why is it secret? Apparently, due to history and a generally closed off ecosystem in FPGAs.
QuickLogic is targetign selling to software engineers, not just FPGA engineers. This has become much easier with python targeting FPGAs (LiteX, Migen)
Software users will help enable more "mass customization"
Making software designs into silicon
Open Hardware Group
RISC V
Global Foundries at Munich
The Artic Pro 2 will be built on the Global Foundries 22FDX, which is their 22 nm process
Hardware/Software partitioning
They're building a test chip
QuickFeather
SensiML is the web-based machine learning toolset. The team came from the Intel Curie group.
SensiML was bought by QuickLogic at the beginning of 2019, but they still offer services for chips outside the QuickLogic portfolio as well.
Chris doesn't think a threshold detect algorithm would be up to the task in many cases.
QuickLogic and SensiML are sponsoring a Hackster contest targeted at projects that will help prevent climate change.
You send in your sensor data, SensiML gives back models you include as a "black box" algorithm
The web interfice allows you to dial in performance algorithms. You can also update the data/model later if you want to tweak based on new data or different parameters.
There is an example data set on github using a PM2.5 sensor
QuickLogic Open Reconfigurable Computing (QORC)
Size of the model depends on perfomance dialed in on the website
The models are set to run on on Cortex-M4, specifically the EOS S3
TensorFlow lite for microcontrollers
APIs for convolution
eFPGA = embedded FPGA
In the case of the EOS S3, it's roughly equivalent to 1000-2000 LUTS
USB in the FPGA without a dedicated (hard) USB core can do USB 1.1 full speed data speeds.
Videos and instructions
- EOS and QuickFeather
- SensiML
  - Endpoint AI without Writing Code
  - SensiML Overview
Building a proof of concept
Community edition of SensiML gives you enough access for entering the contest, trying out models at home (non-commercial).
If you are developing a commercial product, SensiML has commercial subscription prices (Chris thinks they're reasonable, relative to hiring an FPGA/DSP engineer)
Removing the gyro using SensiML
Wrist worn wearables for applications like remote control
Industrial applications
Consumer is still a focus
Gerry Roston talking about data and monitoring for large scale auto manufacturing facilities
They are targeting many of their classic customers in the Automotive / MIL / Aero industry, as well as new ones. They are avoiding the server / datacenter industry.
QuickLogic licenses things like their IP blocks, memory blocks, math blocks for people to design into future silicon.
If you licence IP from QuickLogic (fabric), you will also be able to use Symbiflow for your silicon product.

High Current Power Supplies with Fredrik Kensander Dec 21, 2020

Show notes

Welcome Fredrik Kensander of KraftPowercon!

Fredrik lives in Sweden, one of our first guests from there (Simone Giertz is also from Sweden originally, but now lives in the US)
KraftPowercon makes large scale Switch Mode Power Supplies (SMPS) that are in the range of 100-200 kW output.
Here is a datasheet of an example produce
There are a range of different industrial uses
- HV cleaning with smokestack
- Electrical Preciptator (see them working on YouTube)
- High current electroplating
The high current unit can go as high as 30 kA at 10V
This is used for copper plating in PCB manufacturing
The pulse mode helps to get the plating to happen down into high aspect ratio vias.
Reverse pulse plating use sub-microscecond pulses.
These supplies also found a use in ballast water treatment on ships. The 3 phase power on ships is higher, so they need to have more margin in designs.
Safety in the lab includes plastic covers for dangerous sections, as well as the case being IP44 with front panel on. The lab gets hot because they're often burning so much power.
Manufacturing is on site, but the PCB assemblies are done elsewhere. It's the integration and testing.
Calibration is either done on test stands or in the units that are self calibrating.
What's the architecture of a device like this
- EMC filter
- 24v digital board
- 3 phase goes to powermodule
- 700-800V DC
- Half bridge with IGBTs
- 37 kHz switching
- Snubber
- 5-10W
- Reverse recovery on the diodes
- Inductor
- Current sensor
- Hall effect
- Isolation back to the control side of the board
The control loop needs to respond within 1 pulse, which is roughly 27 uS.
Pulse module is different, it has a lot of caps and an H bridge to deliver the pulses.
Supply chain for a device like this is the "secret sauce" of the company.
Founding of company was in 1935
They received a request to fix a 1937 battery charger.
Fredrik got in touch with Chris writing about "Zephyr without the RTOS part", trying to use similar methods that Zephyr does without taking on the entire RTOS.
He is the software manager at KraftPowercon and working on managing 40 different firmware versions.
He moved them from SVN to Git
Trying to make the implementations all modular
Autosar framework
Replicating the Zephyr API but maybe not using the whole thing
Using different interrupts
Profibus
Processor on each power control module
PRU on the AM3358 (Beaglebone Black)
Jay Carlson talking about STM32MP1
Measuring with scope
Unit testing each module
Test the output that might be going to the IGBT gate
The stack is multiple modules
KraftPowercon is looking for more people
Power factor correction (PFC)
Rick Hartley talking about differential pairs at Altium Live

Inductance and Stuff Dec 06, 2020

Show notes

Dave did a teardown of a plane transponder, so we talk a bit about RF (without much knowledge)
There is a PIC16C84 on board
Learning or relearning
Transmits 1030 MHz, receives 1090 MHz, 140W
We'll ask Jeff Keyzer on the upcoming Keyzermas
Crystal radio is basically a pin diode with long antenna.
Dodgy wiring on 3.5kW aircon
Coefficient of performance
Dishy (Starlink) teardown. Discussed briefly when Joris Aerts (518) was on the show.
Which PCB software is the best? Question posed by past guest Robert Ferenec.
100 Photos vs 1 Photo anecdote
Greg Davill is doing an "Advent for circuit boards". This had been done by Alan Yates for circuits back in 2014.
This is also a thing for learning code, called Advent of Code. These are all based around Christmas traditions (advent calendars)
Chris figured he'll be doing a lot of firmware this winter and asked for advice on Twitter about it.
Bunnie wrote an interesting article about the PCB for the Precursor phone (?) Involves past guests
- Bunnie
- Xobs and Mithro
The Arecibo Telescope has failed and is down for good. The final blow may have been a small earthquake. There are multiple views.
Dave and Chris pretty much agree on the Hyperloop
Train bridge construction in China. That was not from @MachinePix (by Kane Hsieh) but there are lots of great onese if you follow.
Parts
Chris is thinking about trying out the CM4. Not mentioned on the show, but Timon did a copper clad PCB breakout for it and it worked great.
High speed signal guide from TI
High speed getting more common? When Jay Carlson was on the show, he mentioned his intern doing a DDR3 layout easily.

Simulating Embedded Hardware with Michael Gielda Nov 30, 2020

Show notes

Welcome Michael Gielda of Antmicro and the CHIPS Alliance!

We were introduced to Michael by past guest Tim Ansell
Antmicro was a founding member of RISC V, which they first found out about at a workshop at CERN
Open RISC
Renode is "a simulator to build embedded systems faster"
Antmicro is a service organization at their core (contract/consulting services)
They built Renode for themselves
Edge AI systems
CI - Continuous Integration
Can simulate internal and external peripherals for a chip and board
Abstracting building blocks
Renode allows users to put things together in a config file
They have been described as "The Docker of embedded", which Michael says isn't quite true, but shows that Antmicro works within the concept of Containerization
Using Chris's ABC board as an example
We had previously talked about a remote testing setup on episode 512, and how Renode would replace that setup
Users load their compiled binary into Renode.
What can you "see" inside Renode?
Packet analyzer like Wireshark
There wasn't a way to produce trace data, so they built something that extracts it from the simulated processor
The Renode 1.11 release has metrics analysis
Trace tracking
Modeling an accelerometer
Renode Platform File
Everything becomes a test vector
TFlite - Tensor Flow Lite
esting gesture recognition
Pareto
Removing the human factor from the loop
Test driven development
Antmicro is "trying to make hardware boring"
Networking is tough. What if you want to work with a bunch of devices networked together? Renode allows you to simulate multiple high level devices (like a dev board) talking to one another over a simulated network.
Testing packet loss
How do you validate that the simulation represents reality?
Base the simulation data on datasheet
Most systems are only using 10% of the chip (system), in terms of all
Currently integrated into arduino
HDL simulation (transistor level) using Verilator
SiFive - FireSim
Closing the feedback loop
Silicon vendors didn't give what the software people want
Security domain - Dover use case. People prototyping performance.
Polarfire SOC
LiteX
Working with Quick Logic
PDK shuttle runs closing
Open Fabric
How do they decide on what to work on? "We look for things that are really broken and try to fix them"
Working out in the open on CI for TF Lite
"A society of tinkerers"
CHIPS alliance aims to promote open source cores, interconect, and more...but also open source tooling
It is a Linux Foundation project
Intel AIB - developed the spec and code at the same time
Would open source be possible in a place with vertical integration (ie Tesla), as we talked with Joris last week? "Open source achieves a common interface without the scale of Tesla"
For more informtion, check out Antmicro.com
Renode portable package
Check out documentation
One command to run the demo
Looking for marketing people, but more broadly they are looking for people that believe in the mission of open source

Not discussed on the episode:

Michael gave a talk/demo at FOSSi foundation
