Dem still dey develop am · dem neva release am
Open virtual engineering lab for pikin dem
Free engineering lab for every pikin
Pikin dem dey design machines, circuits and robots wit virtual parts, dem dey run engineering simulations, and dem dey see real results wey di lab calculate. If sometin no work, dem go find out why — and make am beta.
- No need for expensive kits
- Phones and computers wey no cost much
- Dem design am to work witout internet
- Plenty languages
Wetin be MEKALUMI?
Virtual lab for real engineering ideas
MEKALUMI na open education project. E bring interactive 2D/3D lab, engineering simulations and lessons wey teachers fit create and share, come one place.
-
Build wit virtual parts
Gears, wires, beams, logic gates, sensors, motors and oda tins: choose parts, connect dem and create your own device.
-
Run simulation and measure
Start di simulation and di lab go calculate wetin happen — forces, currents, motion and signals. You go see results, no be just animation.
-
Learn from your mistakes
If di bridge bend down or di lamp no gree light, dat one na useful information. Change one tin, test am again and understand why.
-
Lessons wey you fit share as files
Teachers go fit create lessons and pass dem give oda pipo as .mekapack files, even witout internet connection.
How e dey work
Five steps wey every engineer dey repeat
Engineering na loop, no be straight line. Every time wey you go round di loop, you go learn sometin new.
- 01
Imagine am
Tink of one device wey fit solve one problem: crane, night light, bridge, robot.
Example: one footbridge “I want small bridge wey fit carry heavy toy truck.”
- 02
Build am
Choose virtual parts and connect dem. Notin dey expensive, and notin go break for real.
Example: one footbridge Put beams across di gap and join dem togeda.
- 03
Run simulation
Start di simulation. Di lab go calculate forces, currents or motion, step by step.
Example: one footbridge Drive di truck climb di bridge.
- 04
Find out
Look di results well well. Wia e bend? How much current dey flow? Wetin move, and how fast?
Example: one footbridge Di middle of di bridge bend down too much.
- 05
Make am beta
Change di design, test am again and explain why di new version dey work beta.
Example: one footbridge Add triangles and di bridge go stiff. Now you sabi why real bridges dey use dem.
Then go back to di start, wit beta idea.
8 engineering areas
From di first gear reach di first robot
MEKALUMI cover eight engineering areas wey connect togeda. Each one get im own experiments, and togeda dem dey show how dem dey make real devices.
Mini lab
Try dis three small experiments
Dis small models dey run right here for your browser, and dem go still work witout internet once di page don load. Na teaching models wey dem simplify, no be di MEKALUMI simulation engine.
Model wey dem simplify E dey run for your browser
Tip: drag di gear for left to turn am wit your hand.
Gear train
Change di number of teeth for each gear. Watch how di speed and di turning force dey change.
- Gear ratio
- 1 : 2
- Output speed
- 15 rpm · 2× slower
- Turning force
- × 2
- Direction
- E dey turn opposite di motor
Wen small gear dey drive big one, di big gear go turn slower, but wit more force. Winches, bicycles and clocks dey use dis idea.
Model: ideal gears wey no get friction and no dey slip. Motor speed: 30 rpm.
Keep di LED safe
Choose battery and resistor, then close di switch. If di current too small, di LED no go light. If e too much, real LED fit burn out.
- Current
- 11.4 mA
- LED
- E dey shine, and e safe.
Resistor dey limit di current. Ohm’s law dey tell you how much: current = (battery voltage − LED voltage) ÷ resistance.
Model: ideal battery; red LED wey get fixed voltage drop of 2 V, and e dey safe up to about 20 mA.
Logic gate
Switch di inputs on and off, then choose one gate. Di lamp go show di output.
- Output
- Lamp dey off (0)
AND: di lamp go light only wen A and B both na 1.
| A | B | Output |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
Logic gates dey follow exact rules, so dis model dey behave like real digital logic.
Na for who?
For pikin dem wey like to sabi tins — and di adults wey dey support dem
-
Pikin and teenagers
Anybody wey dey ask “how e dey work?” and wan build sometin wey be dia own.
-
Parents and guardians
Safe place wia mistake no cost anytin, and every experiment dey teach sometin.
-
Teachers and clubs
You go fit create your own lessons, adjust dem make dem fit your class, and share dem as files.
-
Schools, libraries and communities
Build local libraries of lessons for di languages wey pikin dem dey speak.
Why e important
Talent dey everywhere. Equipment no dey everywhere.
-
Why e free?
Robot kits, lab benches and fast computers dey cost well well. Virtual lab dey comot dat barrier, so pikin chance no go depend on how much moni im family dey make, or on wia e dey live.
-
Why practice?
To read about lever no be di same as to shift im pivot and watch di load dey go up. Practice dey turn formula to understanding, and e dey build di confidence to try, fail and try again.
-
Why e open?
Dem dey develop MEKALUMI as open project, so dat schools, teachers and communities fit use am, adjust am and add to am.
Dem build am for real-life condition
Dem design am for phones wey no cost much and internet wey dey come and go
Plenty pikin dey learn wit Android phones wey no cost much, wey dem dey share wit oda pipo, and wey get small mobile data. Dem design MEKALUMI wit dis pikin dem for mind.
- Dem don test di Android version for emulator wey get 2 GB memory.
- Dem neva test am for real phones wey get 2 GB memory; dat one still dey come.
- Di engineering calculations dey run for di device itself.
- You fit share lessons as files, witout internet.
Di true status
Wia MEKALUMI dey today
- 8 engineering areas wey dem don develop
- 80 lessons wey dem don create and check locally
- 2D / 3D interactive lab
- Android version wey dem test for 2 GB emulator
- Creator Studio for teachers dey already, and e still dey change and grow.
- Dem neva release MEKALUMI for public, so notin dey to download today.
- Dem neva confirm say e dey work for real phones wey get small memory.
For your language
Learning dey start for di language wey you dey take tink
Dem dey prepare MEKALUMI for plenty languages, and dem dey give African languages special attention. Every translation dey show im real status, and native speakers fit help make am beta.
