Hi Evan. I have a project that is 8051 based. Command set is well defined, but we need to overlay a bit-banged I2C command set using GPIO pins. If you accept the project, we will make a good budget for you. The project is an urgent one. Let me know your thoughts. I'm from Detroit.

Hi Ciro L., If you accept this project, we'd create a good budget for you. We have an assembly language assignment that is based on the 8051 microcontroller. We need to essentially recreate an I2C command set and 'bit-bang' I2C on some GPIO pins. Do you think you can do such a thing for us?

Design a device ...characters from internal ROM serially. The user of the device should turn the switch on or off. Initially the switch is ON. Write all your assumptions clearly. Use the 8051 for your design and use 1,200 baud rate. 3. Write a code that read characters from a device called line generator connected to the serial port of 8051 and convert the uppercase characters to lowercase. Use baud rate 19,200. 4. Design a device using 8051 to let the user choose between 9,600 or 19,200 baud rates. The user will print serially the information received to it through a device called MINE connected to port 1. The printer is connected to the serial port of the 8051. Force the user first to choose the baud rate, then allow the device to read MINE and print it serial...

I have a gaming mouse which I would like to have the mouse switches replaced. I required some desoldering and soldering experience which I have none.

Hi Muhammad B., I noticed your profile and would like to offer you my project. We can discuss any details over chat. My project is a very simple 2-sided 80mm x 17mm PCB which has two SMD RGB LED chips and a 7-conductor soldering pad footprint. I will provide a layout drawing, part data sheet, and footprint info.

Hello there! I need someone to help me implement a small program in Assembly. Here is the description: A stopwatch (minutes and seconds) is installed on a track for skying. The skier causes a start of time tracking on the stopwatch as soon as he starts skying and stops the timing at the finish. The following skier clears the previous result on the timer with his start and starts his time display. Write a handler for this system using timer 1 running without interrupts. Basically, I need to implement an Assembly program that works like an infinite stopwatch with minutes and seconds on it. The example with skiers is just for a better understanding of the task. There are no actual skiers involved in the program. :D It can work like, for example, we have a physical button and a table. When ...

I need replacement speakers fitted to my Roland Cube Street EX amp. Apparently only the Left one needs soldering.

I bought a dactyl case and now I need to wire up the key switches LED lights and trackball. Dactyl is an open source keyboard project, the version my keyboard case was modeled after: knowledge of how to follow a wire diagram and solder the parts accordingly. I unfortunately do not have that skill set and the wiring is a bit more complicated than just an average person would understand. The cost of a completed keyboard ranges from $350 - $600 per website: So admittedly the budget for this wiring & soldering is going to be closer to the $250 - $350 range. All parts required to complete the project are ordered on Wich include the Elite-C micro controller amongst other things. Thank you

Develop a microphone array unit using M5stack CORE2 or CORE Basic. Using LM393 MIC unit. I am planning to use: M5CORE 2 or M5BASIC and the MIC unit will be: LM393 Mic Unit or any analog Mic you think is better. using PaHUB (1 to 6 expansion hub) to connect up to 4 MIC unit. Also maybe using ADC unit for each MIC unit. I would prefer a simple hardware connection with little to no soldering involved. But if its necessary, we can talk about it. Would like to see what is your plan. Preferred coding language is Python, but C++ is fine if using ArduinoIDE. Looking forward to working with you!
