Two Good Reasons To Attend Tech Conferences | Voltlog #458

Going to tech conferences and events can be an incredibly rewarding experience, both professionally and personally. As someone who has attended several such events, I can attest to the invaluable benefits of networking and knowledge gain. Firstly, let’s talk about networking. These events bring together professionals from various companies and backgrounds, creating a unique opportunity to connect with like-minded individuals.

It’s a chance to exchange ideas, share experiences, and potentially forge new partnerships or collaborations. In fact, I’ve found that around 80% of the value I derive from attending conferences comes from the networking aspect. During my recent visit to The Things Conference in Amsterdam, I had the pleasure of meeting and conversing with representatives from companies like RAKWireless and Voltaic Systems.

These interactions not only allowed me to learn about their cutting-edge products but also opened doors for potential future collaborations or consulting opportunities. Moreover, the connections made at these events can be invaluable in solving technical challenges. I vividly recall an instance where reaching out to an STMicroelectronics engineer I met at the Embedded World conference in Nuremberg helped me resolve a complex issue within 24 hours – a task that would have taken significantly longer through traditional support channels.

Secondly, attending conferences is a fantastic way to gain knowledge and stay up-to-date with the latest trends and technologies in your field. The presentations, workshops, and exhibitions provide a wealth of information from industry experts and thought leaders. At The Things Conference, for example, I learned about Echostar’s innovative LoRa modules that can seamlessly switch between terrestrial and satellite communication, offering unlimited range capabilities.

In addition to the formal sessions, the informal conversations and networking opportunities often lead to valuable insights and knowledge sharing. I’ve made great friends, like Orkhan, a hardware engineer and fellow viewer of the Voltlog channel, with whom I’ve even collaborated on projects after meeting at a conference.

Overall, attending tech conferences and events is an investment in your professional growth and personal network. The knowledge gained and connections made can open doors to new opportunities, solve complex problems, and foster collaborations that might not have been possible otherwise.

Voltlog #78 – 2x25W Bluetooth 4.1 Stereo Amplifier TDA7492P

In this episode we are going to build a bluetooth speaker amplifier based on the TDA7492P class D audio amplifier coupled with a Bluetooth 4 module. We are not actually going to build the amplifier module because we can get that from China, very affordable, it only costs around $12 shipped which is way less that it would cost us to buy the bluetooth module and the TDA7492P individually not to mention the cost of fabricating a PCB of this size.

So we are actually going to use this module and build the final product with a nice enclosure and a suitable external power supply

Here are some links for the parts used to build this project:
