IMU + USB-to-UART Pmod PCB for FPGA | KiCad + Giveaway - Phil's Lab #26

[@tomnicholls9162]

RP2040 - JLCPCB have recently started offering the RP2040, at the time of writing this they have 162 in stock at $1.1582 (£0.84) here in the UK. Awesome dual core M0+ micro for the price, with good documentation and still available whereas so many micros are on a long back order at present. Would be nice to have a larger development board than the Pico, with a suite of sensors and other components on board to have a play with and some digital signal processing.

Thanks for watching!

Any updates on the course

[@PhilsLab]

Hi Glen, still working on it - taking much longer than expected due to an overall heavy workload. Can't promise it'll be in the near future but it's definitely still in the works :)

[@mt5486]

@@PhilsLab maybe you could release lessons as you complete them. I’d be willing to pay on patreon for early access. Cheers

I'd love to see a design using something like the MCP3561R 24-bit (oversampling) ADC. Measuring ultra-small-scale signals has always fascinated me, but seems to have all sorts of black-magic rules: guard traces? split power supplies? split ground planes? Vref filtering? I would love to see your approach to the problem and see what kind of signals you can measure. As a motivating use case, you could hook one up to an analog accelerometer and try to detect e.g. low-frequency vibrations from cars passing outside without needing an amp.

A Flight Control Unit for small drones, maybe racing quads, with a stm32 would be really cool. Together with that mpu6050 and other sensors

[@thelethalmoo]

I'd love to see a flight controller and video transmitter done well together, I always feel like there are loose analogue cables floating around high-frequency digital stuff and would love to see how someone with knowhow would reduce interference of everything!

[@subramaniantr2091]

Probably one of the best channels. I have a few suggestions. I would expect a video on your lab setup. What are the tools and instruments you have and probably the price also.

[@PhilsLab]

Thank you! Might make a video on lab setup in the future, thanks for the suggestions.

[@krishnaswaroop4591]

What about the course?

[@666aron]

I love to play the guitar, and to design custom audio effects. I had an idea to create a cheap audio interface for smartphones, but I never got to do it. So... Here's an idea for a future project: stm32 based USB audio input card. The amplifier stage can be done with MCP6002, the ADC can be an ES8218, and the IC for audio class an STM32F407VGT6. This setup is enough for a decent audio input. The output can be routed to bluetooth for example.

[@monimonish302]

In two layer board If we do usb design means,how to calculate for the impedance or can you plz tell the trace width n space...if you already done

[@tenij000]

can you tell how did save this to make pick place file

[@FernandoCaT97]

Using any digital potentiometer IC from the JLC STM library to make a 0-10V analog input to 0-100% resistance value

[@denizcancgsar2810]

What happens if you connect UART_TX, UART_RX to FPGA etc, but do not connect the USB to the connector.. Does CH340E pull down the the TXD pin of FPGA?

I missed this, but I'm learning loads, so thanks Phil! Knowledge is so much more useful to me!

@@PhilsLab Thank you for your time Phil! Loving KiCad now after failing miserably the first time around!

Can you make a video of drawing the principle diagram and printed circuit of the wifi transceiver circuit used to broadcast wifi and then use it?

[@lugaidster]

Grab a XC6SLX9-2TQG144C and slap it on to a board with a VGA connector and a bit of ROM and make a simple VGA dumb buffer that outputs an image from a ROM chip on to a VGA display. I would suggest a more modern FPGA, but they seem to be out of stock and prices are somewhat ridiculous.

[@duduc998]

compact LIDAR based wind speed measurement modules for airplanes. It predicts turbulence or cross wind ahead of time so the plane can do some countermeasures. You could use this part e.g.: MFR.Part #STM32F030C8T6

[@gsisk911]

Maybe just the sensor module. To do this right you’d need for more processing power and a complete sensor suite. And it would be best to have this integrated with the flight control computer.

[@johnstephenson4428]

Really good stuff!! Thanks so much for sharing!

[@PhilsLab]

Thank you for watching, John!

Great looking board in black with the assembly service, I look forward to more board designs as I always take away a tip or two....cheers.

[@PhilsLab]

Thank you very much, Andy!

[@Gabi-ct3sz]

What about building a star tracker (and maybe with an image sensor) using an STM32, maybe a H series one for some image processing :>

[@NeuroMod]

FPGAs are fun but and challenging at the same time, I would like to see you design a Spartan 6 board (LCSC# C27408)

[@sebastianfalcone5046]

Loving your channel Phil, greatings from Argentina. What about a Secure key module that prevents the board from working, except when the correct drive is plugged in

[@rodneyosodo]

C69119. This is a SIM800C 24Mbit for 2G/3G/4G/5G connection. The idea is to create an IoT device that used GSM rather than WiFi.

[@mateusraitz1803]

It would be could if you get a CAN Bus transceiver, like one of the SN65HDV series from TI (JLCPBC Basic Part: C12084). I really want to learn more about implementing CAN with STM32. Integrating the transceiver on a PCB with the STM32 chip would be great.

[@Nebulorum]

I would really fin a break outboard based on MCP2515T-I/SO CANBUS would be nice. I'd love to have on that allows power via the CAN cable (say 12/24V) so you can have the power and CAN signal on the same cable and the breakout powering a 3.3V or 5.0V MCU. This would allow on to connect several cheap MCU with a single CAN cable and power the entire network using the breakout and 12V/24V.

[@lukaswalczak93]

I would love to see a Video on the popular ADAU1701JST Audio DSP. It Has several audio channels, high resolution ADC/DAC and can fully be configured with the great software called Sigma Studio. There you can easily design filters and audio effects which makes this IC an excellent choice for a low cost DSP without the need to programm all algorithms by yourself. Because it is widely used, JLC has thousands of them in stock. Keep up the great work.

[@PhG1961]

Great result ! Cool stuff !

Hi Phil, Is it possible for an embedded systems engineer to move from the post of system testing in automobile industry to embedded hardware design in the consumer electronics industry?

how about a video of creating logical gates using transistors ? it would be really interesting to see physical versions of differrent logical gates

I would love to see some digital audio related design. Maybe a development board with an adda and a fpga or something like that for experimenting with audio stuff and dsp on fpga. I don’t have time to look for parts that jlc have in stock so I guess I’m not participating in the giveaway. Instead I’m woting for the guy with the idea of a design with the ADAU1701.

[@mdroberts1243]

I would like a nice complementary PMOD board design that uses the WM8758B Codec from JLCPCB and provides line/mic level inputs and outputs

[@anamemana]

I would like to see someone who actually knows what they are doing like you make a tutorial on how to make the cheapest and smallest possible board around an esp32 so I know I am on the right track with my projects. Could just be one button that sends a message and one LED that displays received messages in morse code.

[@PhilsLab]

Thank you! Yeah, I wanted to have a play around with ESP32s for a while so maybe I'll give that a shot in the near future.

I would like to see something using an ATMega328P. It would be relatable to many beginners. Alternatively, if you are up for a challenge I would suggest an ATTiny85. With only 8 pins you need to get creative but there is a lot of things you can do using i2c. Thanks for making such interesting videos you really help a lot of people!
