I have been running a few experiments with my IN-12 nixies this evening, to try and decide how best to set pulse voltage/current.The IN12 Soviet data sheets do not specify any details for pulse operation, but the side-view IN14 nixies do. ...
The Cree XP-G3 and Luminus SST-20 are close contenders. Naturally the prize of the parts and thereby the final BOM is importand, but likewise the efficacy and real world foton flux. The final current consumption is a big consideration, since the switches...
There are now two new dialog boxes: an alert dialog and a choice dialog. They are nothing special; you can show 3 lines of text and show an icon on them. When the dialog is closed the application module can take the result of the dialog and handle it...
Thi project has to run in "real time" to be efficient. Here are the main considerations regarding hardware and software limits. encoder processing you MUST not miss any encoder step. reading is done by hardware using ESP2 PCNT device : The PCNT (Pulse...
This is for the original design and provides an overview.The TS350 was designed as a portable true sine inverter providing 350W @ 120VAC continuous in ambient environments of -20 to +50C. In boost mode it will source 500W until internal thermal...
Sunday, 09:06 (nice), 18/12/2022 I just wanted to share a little adventure that I had with the Open AI chat bot called "ChatGPT". Basically, it is a chat bot that can code, program and calculate a lot of stuff, and all you have to do is ask it if...
It's been 6 months with the jetson, with only the openpose based 2D tracker & the face recognizer to show for it. 1 problem is it takes eternity to train a model at 17 hours. The conversion to tensorrt takes another 2 hours, just to discover...
This is my first test of MOVI, the speech recognizer and synthesizer. It is very easy to set up and use.The shield works with Arduino and can be found here. I changed one of the sample programs so that the shield would recognize "Mato" when spoken. In...
Now the rev.2 of VHDL/Verilong training board is done!Basically the same circuit but now it's 3.3V operation with XC9572XL (72 macro-cells), which is double sized to the previous one. In addition, 8 Hz (not 8 kHz, also not 8 MHz) clock generator provided...
Custom efficientdet was officially busted on the jetson nano & it was time to try other models. The attraction to efficientdet might have been the speed of the .tflite model on the raspberry pi, the ease of training it with modelmaker.py & that...
Just now I received a very useful information from Hungary. One great user of VHDL training board, which is available at my tindie store, kindly sent me very useful information about .svf file uploader. I got the permission to share this information...
I've been getting amazing feedback about Tipo from all around the world! People seem to be really excited about this, and I underestimated its impact initially. Its is amazing to know that something like this isnt already in the market! Some of the things...
The DRVR code base and robot can now be operated with a cell phone to collect training data, and the training results in a neural network that produces what I think are good results. The code is in the git repository.---------- more ----------The DRVR...
The connector side is almost entirely covered with copper, which is the ground plane for all bus signals. This is essential, because it ensures every signal has identical controlled impedance. The STEbus specification states: 7.6.2 Characteristic Impedance...
I know we have some data accessible in the virufy repo, we need to process this data and workout the label scheme and get it ready for training. Downloading the samples First I need to create a notebook to do the data prep, this will download the samples,...
