From Jenny List on Hackaday:
Building things that fly is hard. The constraints on small, battery powered, radio-operated gear already presents a challenge, but adding weight, balance, and aerodynamic constraints takes it to a whole new level. Sophi Kravitz rises to the occasion and discusses each challenge of building a blimp from start to finish in her presentation at the 2018 Hackaday Belgrade conference.
One of the pleasures of writing for Hackaday comes through the incredible array of talent and experience to be found among our colleagues. We all do our own work, but one is humbled by that which flows from the benches of those one works alongside. Just such a project is the Remote Control Mini Blimp from our colleague Sophi Kravitz. It’s a game involving an obstacle course and a set of remote-controlled blimps. The challenges in such an endeavour have been pushing the limits of what is possible with off-the-shelf components.
So after a series of versions, she had a PCB with left and right motors on two arms and a lift motor pointing downwards, which she suspended beneath the helium bag. Her controllers are simple enough 3D-printed joystick housings, with another ESP8266 within. The blimp ESP8266 forms a wireless network to which the controller connects.
We’re still coming off the Hackaday Belgrade conference right now. If you were there, you know it was the greatest hardware conference ever. If you weren’t there, you missed out. Sorry. (Make sure you get in on the Hackaday Superconference in November.)
One of the many highlights of the Belgrade conference was, of course, the badge. The 2018 Hackaday Belgrade Badge is a masterpiece of hardware with a 55-key keyboard, RGB TFT LED, speaker, and a BASIC interpreter.
This badge is a masterpiece of electronic design by Voja Antonic. Just to take one small example from the design, check out the placement of the buttons. Think the slightly rotated buttons that make up the keyboard is only a stylistic choice? It’s not; by carefully rotating each button, the legs of each switch can fit in between each other. It’s brilliant.
