We are developing an advanced microscopy system and need an expert in high-speed circuit design to help optimize our laser diode control mechanism. Specifically, we aim to synchronize a laser diode with a camera's strobe signal to achieve fast and reliable switching without compromising stability or performance at high frequencies. Key Requirements: Experience designing MOSFET-based switching circuits for precision applications. Familiarity with gate driver circuits and ensuring stability in high-frequency operations (100 MHz and higher). Proficiency in minimizing turn-on and turn-off delays (10 ns or less) in diode control circuits. Strong understanding of logic-level signal integration (1.8V or 3.3V) and compatibility with higher voltage/current components (e.g., laser diodes requiring 5.4V, 50 mA). Ability to troubleshoot, optimize, and validate PCB designs for high-speed applications. Project Scope: Review our existing PCB design and schematics (provided after hiring). Identify and resolve stability issues in our gate driver and MOSFET switch circuit. Optimize the system for fast, reliable performance in synchronizing the diode with the camera’s strobe signal. Suggest alternative solutions if the current design cannot meet performance goals. Deliverables: Technical review report detailing issues and suggested improvements. Updated circuit design or schematics (if applicable). Guidance or testing procedures to validate the updated design. Preferred Qualifications: Strong background in electronics or electrical engineering. Proven experience with high-speed modulation or switching circuits, particularly for laser diodes or LEDs. Familiarity with CMOS camera interfacing and Jetson Nano GPIO control is a plus.
We are seeking a skilled electrical engineer to review the wiring descriptions and photos provided for a 17" by 13" enclosure in an effort to help us produce some digital wiring schematics. This is a relatively simple project with off-the-shelf components mounted on 35mm DIN rails, combining an AC power input with a few DC PSUs and relays. Some added detail: - open to a variety of schematic softwares, including SkyCAD, options with free versions preferred - current enclosure has a split-phase power setup, which we need to detail along with the three-phase adaptation - parts are already tabulated in an excel spreadsheet - physical positioning / panel layout is not important - a small review and engineering recommendation would be appreciated after diving in with our engineer on what is built If you have a strong background in electrical engineering and diagram assembly, we would love to hear from you!

Hello, Need assistance with setting up Keylab 49 key and Arturia Analog Pro VST. This keyboard and VST should be plug n play but for some reason it's not working. I need to simply fix the settings so that I can scroll my presets with the keyboard. Also, a bonus if you know how to scroll presets on other VSTs using my midi keyboard.
Steady state power flow analysis under minimum and peak loading. The generator connected to Bus 1 represents the grid in-feed • The fault level at the grid in-feed is 850 MVA. • Two 132/33 kV transformers connected between Bus 1 and Bus 2 supplies power from the 132 kV transmission system to the 33 kV distribution network. • A 33/24 kV transformer between Bus 7 and Bus 8 connects to the Renewables Farm (RF). • The renewables plant includes a 10 MW solar PV farm. For power system studies this may be modelled as a 10 MVA synchronous generator Carry out a load flow analysis on the network using the IPSA software package. Use a base power of 100MVA and assume Bus 1 as the slack bus. I'll share more details
The aim, in this phase, is to create a quick POC. It will be enriched and made more professionally operational at a later stage. Choose a microphone that connects via Bluetooth to the Android smartphone - Collect breath sounds continuously from the microphone, in a noiseless environment - Process the signal to create the envelope and count the peaks. This processing can be carried out in real time on a PC nearby. - Measure the frequency of these peaks - Display this frequency measurement, in real time, for example every 2 peaks, on a curve on the Android mobile, smoothing it out.
We are working on a smart mattress pad that can be configurable through our mobile app. And we are looking for somebody who can help us with the firmware development. The mattress pad has ESP32 module installed. The mobile app needs to be able to pair with the mattress pad via bluetooth and transfer the WiFi network credentials to the mattress pad. Then, the mobile app and the mattress will be communicating to each other via AWS IoT API. We already have the backend and the mobile app engineers, but we need help with the firmware for our ESP32 module. Our team is Russian speaking (located in Belarus and Poland). So we will need somebody who speaks fluent Russian to be able effectively communicate with the team members.
