I want a working prototype of a truly pocket-sized gadget that can run completely offline. The flow is straightforward: a standard-resolution camera captures a printed or handwritten question, an on-board OCR module extracts the text, a lightweight language model generates a full textual answer, and the reply appears on a small built-in screen. No cloud calls, no external power brick—everything must live inside the device itself. I am open on the exact OCR library; Tesseract OCR is the obvious first choice, but if you have a lighter or faster alternative that will compile on something like a Raspberry Pi Zero 2 W, an ESP32-S3, or any comparable single-board solution, I’m happy to discuss it. For the AI model, please keep it compact (e.g., TensorFlow Lite, ONNX, or sim...

Looking to design prototype simple thermostat with separately mountable LCD display. Two thermistor temp inputs. One 220V 10a relay output. Its to run a water chiller, set point is fixed at 6C. So one of the temp input measures water temp. Switches 230V 10A relay on if Water Temp >8 and off it temp is <6 C. (Hysteresis avoids rapid switching). The second temp input switches the relay OFF (regardless of the water temp) if its temperature input exceeds 35C. Ideal is to protect from overheating. Its just monitoring the air temp inside the unit. The LCD should display the two temperatures and the relay status, eg 10 28 1 Could mean water temp is 10C , air temp is 28C and the relay is ON. No temp adjustments are needed. We will pay for hardware and costs to...

I want to put together a quick-and-dirty paper prototype that proves one thing: textual instructions can be fed into an LLM, interpreted, and turned into accurate anatomical motion that I can later visualise in my copilot 3d js etc. The workflow I have in mind is simple on paper yet technically layered. First, the LLM receives short, structured cues (“Raise left arm to 90°”, “Rotate torso 15° right”, etc.). It must parse those sentences, identify the key actions, and output a sequence of joint-level positions. From there, the prototype should pass those positions to a lightweight Vision-AI / pose-estimation module so I can preview the motion as stick-figure frames and sanity-check anatomical correctness. Because this is an early prototype...
