Mechanical Haptic Heart Design

I am looking for a CAD/Product Designer to engineer an internal housing and mechanism for a small, functional haptic prototype. I am using a standard micro servo (SG90) as the power source. Requirements: The goal is to convert the rotational movement of a 360° SG90 servo into a strong, simultaneous physical pulse on both the left and right sides. The closed enclosure must form a stylized, emoji-like heart shape with a rounded bottom. like the example. And all parts must be optimized for 3D printing. So think of making it in parts instead of 1 piece

Product Engineer Needed. Mechanical / Injection Moulding

I’m developing a physical product and looking for a product/mechanical engineer to help bring it to life. This is not just a simple CAD job... the product involves a custom internal mechanical system, so I need someone who can help think through and refine the mechanism, not just draw it. Project involves: • Developing a functional mechanism (moving/interlocking parts) • Creating initial concept designs before final CAD • Advising on manufacturability (likely injection moulding) • Identifying potential design risks early Ideal experience: • Mechanical systems / moving parts • Snap-fit, locking mechanisms, or similar designs • Injection moulding / DFM (design for manufacture) I’d prefer to work in stages. Starting with concept development, then moving into CAD and refinement. Please include examples of similar work (mechanisms or physical products), not just general CAD. Looking for someone who can contribute ideas and problem-solve, not just execute instructions.

Looking for talented product designer

We are currently developing a sports app that combines the web and blockchain. We have already completed NitoGem, a basic demo version focused on the Web3 layer. NitoGem is already in service as a dApp, allowing users to register tokens and vote using ETH. Voting results directly impact rankings and exposure. The core system is already established, including wallet connectivity, smart contracts for voting and credit management, and an off-chain layer handling indexing and ranking logic. While it is currently operational, it is still in its early stages and requires improvements in terms of design and workflow. We are moving forward in a direction of evolution rather than a complete rebuild of the system. We plan to extend the same system beyond cryptocurrency to other fields, such as sports, where user engagement influences rankings and exposure in a similar manner. We will maintain the core mechanisms while gradually expanding use cases as the platform matures. We are looking for talented designers to help achieve these goals. If this project is successfully completed, we can develop a long-term partnership. It can be helpful you have knowledge of web3. When are you available to join? What are your strengths?

802.1x WiFi Setup for Schools

We need a network engineer to set up 802.1x WiFi across three school sites. Users utilize Entra ID and M365, and there are Netgear APs with no servers onsite, just firewalls and switches. The ideal candidate will have experience in network administration and be able to work with Entra and M365. I use Netgear Insights to manage the hotspots across all 3 sites. I can remote to each site via a PC on each site via Teamviewer. At moment I've set up WIFI ID and PW. However, the government say that this is not good enough and the wifi needs to use 8021x and be certification based. I've looked at using Cloud based authentication but there's a monthly cost, I want someone to provide me a solution where it's all internal, the devices are shared, so they must authenticate to the wifi and I don't want to subscribe to anything, just set up internally. Don't mind if a server is needed, I am phsyically close by to all 3 sites. London / Surrey UK based schools, please provide me with a fixed price for whole project. Devices are Win11 laptops and iPads. All devices are on Intune. Any other questions, please do not hesitate to ask...
