All additional components purchased and ready to go. So far I have prepared the game cartridge cutting all required holes for ports and trimmed some plastic from the bottom to make the Raspberry Pi . First time cutting plastic to create port holes so...
The LG display allow to select the LVDS mapping between JEIDA and VESA. I encountered such issue again and images were generated to help diagnose the issue.The original image is pass through the conversion mapping to obtain the VESA and JEIDA images.----------...
It seems I have reached the base camp. The el-cheapo 7-inch LCD monitor on the right is connected to the output port of my breadboard TTL computer. The computer is now running at 6.3MHz and runs a software loop that generates a VGA test signal. The colors...
A80 Teardown The newer A80 with QHD at 30 fps and 4K24p capabiltiy (20MP still frames) has a lens shroud that is tucked under the front cover (left), which needs careful persuasion for its clips to release without breaking. The short sides appeared to...
For the Thor robot I use the Ultratronics v1.0 pro board which is basically an Arduino Due. The touch panel that I want to use is the Nextion 7" HMI panel. These are the steps that I had to take to make the panel work with the Ultratronics board.The...
Development on the V9958 board continues apace, and after a false start due to a silly mistake in the first revision things are back on-track with a revision 1 prototype. The design is now validated and working really well. So far it's baby-steps in...
This Blog will Cover How to build a cheap EC meter for your aquaponics/Hydroponics or water quality related projects. We are not going to get into what the ideal value of PPM or EC is, Just cover how to measure and quantify a fluid.We will be using this...
20200810: see 122. Updated Gray Counter for the rest of the story !I must make a Gray code counter ! It is not obvious why but it's an important piece of circuitry that is required by the debug/test port... Have a look there for some background :4. The...
Mechanical assembly- Stepper motors into parts A1 & A2- Ends B1 & B2 slot into A1 & A2 to make a rectangle (B2 has no tabs, it goes in at the hook ends of A1 & A2)
- A1,A2,B1,B2 assembly snaps into base C (line it up and pull the two spring clips back if necessary)- Tape a nut into slots on B1 & B2 (tape on one side should be enough to stop the nut falling out)
So I started to write the dependencies of components down and realised that Room > Frame > Gantry > Slime is wayyyyyy better than trying to go the other way around. Thus, I'm currently modelling the location in the room where the printer is going. I...
Wie schon im letzten Blog geschrieben, war ein Breadboardaufbau buggy. Tatsächlich war nur eine Adressleitung (A14) nicht richtig verbunden, direkt am CPU Pin. Also hab ich das Breadboard hinten aufgemacht, die entsprechende Kontaktleiste raus genommen...
Nun geht's richtig los. Jetzt wird ein EEPROM (AT28C64 8Kx8) angeschlossen. Und da das RAM ja eh auch bald dran ist, hab ich das gleich schon mal mit verkabelt. Zunächst aber nur Adress- und Datenleitung. Die Steuerleitungen vom RAM sind alle auf...
Principles of Linear Stepper Motor A linear motor is a transmission device that can directly convert electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotating electrical...
