I’m developing a next-generation Bitcoin miner, internally labelled “400,000,” and I need an engineer or small team to drive the research-and-development phase. My priorities are clear: push Energy efficiency as far as current silicon will allow, unlock higher Processing power than today’s leading rigs, and experiment with new or optimised Mining algorithms. I also want the design to remain flexible enough to switch over to Bitcoin Cash should comparative profitability shift. At this stage the unit’s final home is undecided—my form literally says “Dinner,” which simply means I’ll be bench-testing the prototype in an ordinary room rather than a purpose-built data centre. Noise, thermal load and power draw therefore have to stay within l...
The existing board is finished and working; the only task still open is replacing two connectors: • Change the current USB connector to a USB-C footprint that I have already created. • Replace the end-of-board black connector with an IDC-Connector-2x3 footprint, also ready to drop in.

I don’t have to hit a formal CISPR or FCC limit this time, so yo...
I am looking for an expert Electronics Design Engineer to review, optimize, and finalize a draft KiCad schematic for a custom, battery-powered audio logging device. The core architecture relies on an ESP32-S3-WROOM-1-N16R8-1U module paired with a TDK T5838 digital microphone featuring Acoustic Activity Detection (AAD). The device operates primarily in an ultra-low power standby mode: the ESP32-S3 stays in deep sleep with Wi-Fi completely turned off, while the TDK T5838 remains always-on to monitor the acoustic environment. When a sound trigger occurs, the microphone must wake the ESP32-S3 using an AAD interrupt (via D1, D2, or Analog AAD mode) to record audio onto a microSD card. The ESP32-S3 will wake up its Wi-Fi radio only during a specific, firmware-defined time window to transmit the ...

Two of my grill-sensor cables lost their 3.5 mm tips when the plugs were yanked out. The conductors are still intact, so the job is a straightforward re-termination: remove the damaged ends, solder on brand-new 3.5 mm connectors, and add proper strain relief and heat-shrink so the leads can handle outdoor use. I don’t yet have the replacement plugs and would appreciate your guidance on the exact TRS/TRRS style and brand that will mate cleanly with the grill’s jack. Once I order (or you supply) the parts, I’ll ship the cables to you—or, if you’re local, drop them off—to have the work done. Deliverables • Two fully functional cables with new 3.5 mm connectors, electrically verified for continuity and short-free operation • Photo (or brief vid...

Compact size is the top priority, so I expect smart component selection, tight transformer design, and a PCB layout that keeps both footprint and height to an absolute minimum while still meeting creepage, clearance, and EMI/EMC requirements. Although efficiency and low standby losses matter (this will ...
My laptop’s battery plummets from full charge to near-zero in under an hour even with light browsing, so I’m certain the issue is hardware-related rather than software bloat. I need a technician who can confirm the health of the battery pack, inspect the charging circuit, and swap in a quality replacement if that proves to be the culprit. Ideal workflow: run a quick diagnostic, show me the results, replace or re-cell the battery, then calibrate and stress-test so we can verify that normal run-time has been restored. A brief report after testing will wrap things up. If you have the tools and parts on hand and can offer at least a short warranty on the fix, let’s get this sorted.
I have a batch of 51-100 boards that need careful through-hole soldering, plus a small run of matching wire harnesses and a few damaged PCBs that require touch-up repair.
