Re: [TriEmbed] Triembed - Open Proposal

Hi Kevin,   What about a cheap but capable board that could host Android and provide a platform that could run many "smartphone apps" without the "smartphone cost"? Some kind of AI acceleration would be a plus. -Pete On 10/26/20 2:57 PM, Kevin Schilf via TriEmbed wrote: Triembed, From

[TriEmbed] Nucleo 32 board cautionary tale

I just wasted a good chunk of a day chasing weird sensor behavior with a Nucleo STM32F031K6 board. After seeing three flavors of other misbehavior on top of the little detail of the sensor giving goofy measurements it occurred to me to look at the sensor chip power supply fed from the 3.3v pin

[TriEmbed] stm32 bootloader interface for the rest of us

I'm investigating easy ways to flash a low end STM32 chip through it's UART and the (STM32F031x6) datasheet had about 10 words on the subject. But I found the 374 page doc below. Before I dive into that I wonder if there's a simple program that runs on Linux or Cygwin to take whatever binary

[TriEmbed] more detail to the "attaching to the copper tubes" Re: OT: RF questions

One more detail that might be of general interest. The place where you attach the xmit output and ground to the two dipole legs determines the feedpoint impedance. If you attach to the closest practical two positions near the center the impedance will be at or near what the model predicted

Re: [TriEmbed] OT: RF questions

I think it's going to be GREAT! And which end is down is perfectly arbitrary if there's no circuit ground path to the "outside". And if it were me I'd try it and if signal strength is poor then consider a balun.  I didn't spend much time with the datasheet but couldn't figure out what the

Re: [TriEmbed] OT: RF questions

I modeled 1/2" diameter elements with EZNEC and the length of each 1/4wl element comes out to 29.1 inches when cut for 98MHz with the antenna 10 feet up. The graph of SWR vs frequency from 88 to 108MHz is below. The closer to resonance the lower the
