I wanted to make a terminal connection to the BeagleBone AI board I have, just to make sure I could still do things if I messed up elsewhere - which is something I have done with other boards. I am using a FTDI232 board to make the connection to the BBAI terminal connector. As I was buying one of these boards for the BBAI I decided to buy one as part of a package with an ESP32 CAM and some Dupont cables for later fun.   I was able to obtain a suitable cable (thanks shabaz ) that connects t ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   The Artificial Neural Network that I want to use with the LDR camera and the BeagleBone AI is one derived from a book by H Pao. As it has been some time since I used this programme I thought it would be beneficial to refresh my memory of how it works. Fortunately I have a cop ...
I am trying to find a connector and wires for the 3 pin TTL serial connector on the BeagleBone AI. I know that it is 1.27 mm spacing but I have not been able to locate anyone who can sell me a connector with wires and connector. I have purchased a FTDI USB to serial convertor with 0.1 inch spaced pins for Dupont connecting wires so I just need to convert from 1.27 mm to 0.1 inches (2.54 mm). I know they exist, I just cannot find any.   I can remember reading about this in a comment on one ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   As I cannot think of any more excuses for not powering up the BeagleBone AI so that I can use it to run the ANN for my LDR Camera, I decided to try and get it going. I thought I had a Raspberry Pi 3 power supply that came with a Type C connector but as it turns out, I haven't ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   As I am currently restricted to my home office at the moment (the plaster is in doing his thing) I have spent some time progressing the LDR camera, which is now working on all 64 pixels. I had one non working pixel and rather than try to fix the hardware wiring rat's nest, I ...
Vision Thing Enter Your Project for a chance to win an Oscilloscope Grand Prize Package for the Most Creative Vision Thing Project! Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   The LDR camera is working! Well, almost. 98% = 63 of the 64 pixels are working. Just one is refusing to work properly which is not too bad as it has only just been finished constructing and wiring everything together. It is probably  loose or broken connection somewhere, ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   All the parts I needed for the LDR camera have now arrived, well almost - the correct Dupont connectors have not yet arrived but I think I might just about have enough existing ones to be able to connect everything together. As my 3D printer is still not working (I haven't tr ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   The parts to make the 64-to-4 analogue multiplexer arrived this afternoon so I immediately put them together. It is not quite finished yet as I have to parallel up the control inputs to the all the boards. Still, it looks OK. I just hope it works. I now have enough LDRs to ma ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   I was excited today to be handed a small parcel by UPS just as I was going to Tescos to buy some shopping, thinking it would be the LDRs and stripboard I need to create the full 8x8 pixel LDR camera. Eventually I returned home from shopping and let some time pass before openi ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   Following on from getting the 1x8 LDR array to display on the 8x8 LED matrix display with just two levels (ON and OFF) I tried implementing my idea of multiplexing the whole display in software to create a sort of PWM effect that might mimic grey scale display. The GFX librar ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   While I was waiting for the analogue multiplexers to come that I need to make the rest of the LDR camera I decided to add an 8x8 array LED display as I just happened to have one (thanks shabaz ). This is a fun display using a HT16K33 to drive an 8x8 LED array using the SPI in ...

Back to The Project14 homepage Project14 Home Monthly Themes Monthly Theme Poll   Having thought for a while about what I might be able to achieve for the Vision Thing Project14 competition I have decided to try and create a system that uses Artificial Neural Networks (ANN) to recognise images or shapes from a simple grid array camera. I didn't want to use ...
