rocket launch control

thingiverse

After many weekends of watching my younger cousin fail to be able to squeeze the launcher safety and smash the launch button all while screaming the countdown is long over!! I used an existing Estes launcher and overhauled it with our own style. heavy duty safety switches and a 9v battery to really get those igniters going! I used the led light/resistor circuit board from an Estes style launcher and soldered a positive and negative wire to the board inner square being the positive and the outer ring being the negative. also used the long leads with the alligator clamps already attached. 12mm momentary push button switch https://www.amazon.com/Twidec-Waterproof-Momentary-Modification-Switch%EF%BC%88Quality/dp/B07P93X4BW/ref=sr_1_10?dchild=1&keywords=push+button+switch+red&qid=1628168058&sr=8-10 Nilight 90014E Heavy Duty Rocker Toggle Switch 12V 20A Red Cover SPST ON/Off 2Pin Car Truck Boat-5 Pack, 2 Years Warranty https://www.amazon.com/Nilight-90014E-Rocker-Toggle-Warranty/dp/B07QKFD7Z7/ref=sr_1_3?crid=2LCS0OK5DGLY6&dchild=1&keywords=nilight+90014e+heavy+duty+rocker+toggle+switch+12v+20a+red+cover&qid=1628168188&sprefix=nilight+90014%2Caps%2C190&sr=8-3 9v battery t style connector https://www.amazon.com/Battery-Connector-Plastic-Experiment-Equipment/dp/B08SL9X2YC/ref=sr_1_1_sspa?crid=35X9T7E7V7UP4&dchild=1&keywords=9v+battery+connector&qid=1628168274&sprefix=9v+batter%2Caps%2C204&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExMTZDM1JCSkxVSTA5JmVuY3J5cHRlZElkPUEwNTAyNDg2M1RPN0lRU09QSFM4SyZlbmNyeXB0ZWRBZElkPUEwNzIwOTMzMlRCVFJLTUxQQzNXUiZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU= 1x M3x14mm button head screw and one nut for handle 1x m3x8mm button head screw for cover
