24 alternatives to Joy
Most peptide calculators ask the wrong question. They ask: How much water are you adding? But in practice, what you actually know is your vial size and your target dose. The water amount should be the output, not the input. It should also make your dose land on a real syringe tick mark. Not something like 17.3 units. I built a peptide calculator that works this way: https://www.joyapp.com/peptides/ What’s different: - You pick vial size and target dose → reconstitution is calculated for you - Doses align to actual syringe markings - Common dose presets per peptide - Works…

diskprices.com, but for Protein Powder! Buying protein powder is a mess, and comparing different products is frustrating, since all brands choose their own serving sizes. By collecting nutrition facts, and normalizing the serving to contain 25 grams of protein, we can properly compare price/nutrients per serving. Inspired by diskprices.com, the idea is to provide an equally functional interface to compare products. The prices are collected once a day, currently from iHerb US. Aiming to improve the coverage soon. Any tips / suggestions / other feedback more than welcome :)…

The core question: how did HP's scientific calculators actually work at the gate level? That rabbit hole led to building one from scratch. The architectural decision everything else follows from: a decimal calculator should store numbers as BCD — one decimal digit per 4-bit nibble. A standard byte-oriented CPU (Z80, 6502) fights that layout constantly. So I designed a small custom CPU in Verilog where 4 bits is the natural data width and memory is nibble addressable. What the project covers: - Custom CPU: Harvard architecture, 12-bit ISA, 8-state execution FSM, hardware stack guard with a…
