Just ordered qNinjaLite:batch2/main with updates to reduce parts price. BOM will be updated later. Removed pricy and discontinued demodulator ADA2200 Adhoc FFC connector to choose best photodiodes. We already picked PDB-C152SM but other ones made by a company named OSRAM looks better and cheaper. All of their candidates are already soldered onto optical unit of … Read more
DNA chromatography chip for PCR was what I want to make in 2016 before pandemic. Now I need lyophilized chip of reagents for qPCR/qLAMP. Contact me if you can join.
Latest photos of $300 qNinja (qPCR+qLAMP) and $50 qNinjaLite (qLAMP) https://github.com/hisashin/qNinja https://github.com/hisashin/qNinjaLite
Received NinjaLite boards and metal parts from Shenzhen in lockdown (14th-20th). DHL transferred to Shanghai 16th afternoon and delivered within 2 days.
Current NinjaLite parts price is $68 for 1×8, $106 for 2×8. If we can find better alternatives of photodiodes, aluminium 3d printing and emission filter, it would be cheaper.
Just started converting qNinja (qPCR+qLAMP) to qNinja Lite (qLAMP) to be sent to Ukrainian citizens to prevent outbreak, water pollution and so on.
Here’s the wet result of qNinja optical sensors using fluorescein sodium solution that simulates COVID-19 sample. Shortly speaking, we can expect that even a single copy of target DNA per tube can be detected well enough. Actual amplification with DNA will be held by ourselves and 3rd-party soon. 1. In some papers, COVID-19 swab sample … Read more
Almost getting PoC, proof of concept of Ninja LAMP and qPCR. Total cost is roughly $26,000(JPY3,000,000) and 1.5 year of 2 engineers, I and my wife. ・$1621.37 for PCB (Seeed+PCBWay) ・$5020.83 for PCB parts (Digikey+Mouser+Verical) ・$7692.67 for other parts (Aliexpress and Thorlabs) ・$6248.26 for tools (laser cutter and others) ・$2424.83 for first evaluation by third … Read more
First fully assembled qNinja. Single/Dual optical unit is replacable for multiple wavelength. This prototype will be compared to commercial qPCR next month.
