An open-source Arduino base remote controller (transmitter) with many customization options for robots and drones.
Project in progress by syamil_zaini and alirezasafdari
This project aims to provide insight into the workings of a digital oscilloscope. This project is designed to be an education tool.

Timing the processor is going to be the most challenging part of this project. Good Luck.
"we have already THE JUMPER TX multiprotocol, and the ATMEGA MULTIPROTOCOL"
"JUMPER TX multiprotocol" It is great but we are not doing the same thing
"ATMEGA MULTIPROTOCOL" It is great too but we are not doing the same thing
The mentioned products are good for working with various RC protocols but this is not the goal of Alpha V1. The goal of Alpha V1 is to give users a simple and reliable remote controller that can be easily modified and customized.
Let me know if you have any other question. I have answered A. Herlas questions in the previous comment. You may want to have a look.
Hi A. Herlas
Glad that you found it pretty nice.
Regarding your questions:
Q1) They are not different versions of Alpha V1. Although I understand where the confusion come from. Those 2 other configurations are just presented to show the possibilities with Alpha V1 when adding other input devices. I am going to change the caption and title to make sure the confusion does not happen for other readers.
Q2) We have spent many hours to design Alpha V1, Syamil has been/is a product designer for home appliances in Panasonic so he is very familiar with ergonomic aspects. We have built many prototypes and considered the ergonomic aspects in each iteration, so it is very unlikely that you would not like Alpha V1's feel. But if (for whatever reason) you do not like it, the mounting for the outer shell (the yellow part) is 3D print friendly. So you can 3D print your design or another design developed by the community. If you do not like the upper plate, all you need is a $30 laser cut acrylic with your design or a community developed design. Having said that, I doubt if you would not like Alpha V1 in its current shape. Also consider that the other transmitters in market do not give you any of these possibilities and many people with small hands find them hard to hold.
Different prototypes of Alpha V1 have been used in various robotic competitions and we have used all those experiences to improve the ergonomic aspects of Alpha V1,
Q3) As mentioned under "COMPONENTS AND SUPPLIES" we are using Xbee. Xbee is not compatible with any of the existing RC systems but it is a step forward because it outperforms them. We are currently not using Xbee 3, which has been released recently, but if we make sure that Xbee 3 has the same performance as the previous versions then we use Xbee 3. Xbee 3 has Zigbee, 802.15.4, DigiMesh and BLE all in one package.
Q4) The Xbee we use in Alpha V1 is 2.4GHz but DIGI (Xbee's manufacturer) has other products that can replace the 2.4 GHz version and they operate at 900MHz (For US) or 863-870MHz (For EU).
Q5) We have made 3 different receivers so far with different features. But we think that is going to be confusing for users. So we are working on a stacking solution. So based on the features you need, you will have to add stacks. This way the size of the receiver would be based on what you want to get out of it. In terms of feature, in our initial release we support almost everything from RC world + raw analog (more than the 2 available in some RC receivers) and digital inputs.
We expand the firmware to support more features in future to make the robot end easier. Meanwhile many robotics folks can develop their own code if they need very specific features and of course the community will be able to help too; because Alpha V1 is Arduino Base.
If you think this is a prototype, you are not wrong because it is a prototype by definition but it is very close to the final product. PCBs are done (for the remote end), Firmware development is at +80%, the fabrication and manufacturing process has been studied and analyzed too.
Sorry for the long reply but wanted to make sure everything has been clarified.
