Resources

Tools you can use right here, plus the guides and templates we use ourselves. Nothing to download to try a calculator.

Maker tools

Resistor colour codeRead a resistor's value straight off its coloured bands. 4-band and 5-band.
LED resistor calculatorSupply voltage and LED forward voltage in, the resistor you need to buy out.
Wire gauge & voltage dropCurrent and run length in, a safe AWG size and the voltage you'll lose over the run.
3D print cost estimatorFilament weight, print time and your rates in, a price to charge or budget out.
Unit converterLength, weight, volume and temperature — metric and imperial, either direction.
Ohm's law calculatorVoltage, current, resistance, power — fill in any two, get the other two.
Find a makerspacePick a city or state — see a CoMakers space nearby if there is one, and search the wider web either way.
Import landed costA supplier's price in dollars in, what the machine actually costs to get into your workshop out — freight, duty, VAT, levies, clearing and haulage.
G-code generator (laser)Laser-cutting G-code from a rectangle, circle, hole grid, or your own SVG's actual paths.
G-code generator (lathe)Turning G-code for a stepped or tapered shaft, a spherical end, and grooves.
G-code cheatsheetWhat every common G-code and M-code actually does, in plain English.
3D print troubleshootingStringing, warping, layer separation and more — causes, and what to fix before the next print.
Print settings by materialStarting nozzle and bed temps, speed and cooling for PLA, PETG, ABS, ASA, TPU and Nylon.

Files & guides

Guides

Maker Basics HandbookA grounding in workshop practice, measurement and safety for people starting out.
What a makerspace costs in NigeriaOpening one, and keeping it open — landed cost of imported equipment, where the capital goes, and the monthly line that decides whether you are still open in three years.

Safety

Safety HandbookOur workshop safety rules, machine by machine.

Reference

Conversions, tolerances and common thread sizes on one page.

Circuit Symbols ReferenceStandard schematic symbols for electronics work.

Templates

Workshop Tool Maintenance LogThe log template we use to keep machines serviced and safe.
Maker Project Documentation TemplateA structure for documenting a build so someone else can repeat it.
