20Pcs DIY FLA-1 Simple Flashlight Circuit Board Electronic Kit
A part of the review has been auto-translated.
Ventajas: Muy interesante con fines didácticos y para practicar la iniciación a la soldadura de componentes. El circuito es fácil de realizar y la linterna alumbra bastante. Gracias al tipo de circuito (ladrón de Joule) es capaz de extraer energía incluso de pilas bastante gastadas. Existen packs de menos unidades. Desventajas: El agujero frontal es demasiado pequeño para el LED, por lo que es necesario limar a cortar el plástico a mano. No incluye ningún tipo de instrucciones de montaje ni explicación del circuito.
this diy kit was just as described. i am totally happy and i will order it again. i use it on teaching electronics to my students and they are all impressed.
Really good piece of kit. Pretty easy to put together, but the battery holder springs are a little fiddly. We used these kits to introduce a group of childern (ages 9-11). Most of the kids got them to work- one or two needed some trouble shooting, but all worked. Really anjoyable exercise, though additional (adult) help needed with the battery holders.
Works as stated, a great little starter kit for anyone wanting to get into electronics and build something useful.

Light well!
The components appear to all be there. No instructions but easy enough to figure out. Students will be using them to learn to solder. Price is great. They came earlier than expected.
